Pilates for patellar tendinopathy (jumper's knee): loading the tendon, which moves to change, the pain rule, the evidence, and a routine

No trial has tested Pilates for patellar tendinopathy, which most people call patellar tendonitis or jumper's knee; there are two single case reports. What helps is loading the tendon in stages, holds first, then slow strength, then springy jumping and then sport, while keeping tendon pain at 3 out of 10 or less.

Lying and side-lying Pilates should put little load on the tendon (our reading, from a study that tested no Pilates moves), so Pilates helps most as the session around that plan: hip, trunk and calf work, with the plan's first-stage hold built in and the moves that strain a sore tendon changed. It doesn't replace the loading plan, the cut in jumping or a physiotherapist's assessment.

This guide covers what loads the patellar tendon, the pain rule, the reformer, what the evidence shows, which moves to change, a free 25-minute class, and the warning signs. Our jumper's knee guide has the full plan and its stages. If you felt a sudden pop below the kneecap and can't straighten your knee, go straight to the warning signs.

The short version

No Pilates trial

No trial has tested Pilates for patellar tendinopathy; there are two single case reports. Pilates is the session around the loading plan, not the treatment.

Sources 1, 2, 3

Loading the tendon in stages is the treatment

In the largest trial (76 athletes), a staged programme of holds, then slow strength, then springy jumping, then sport, beat painful decline squats at 24 weeks. Our jumper's knee guide has the plan.

Source 4

Keep tendon pain at 3 out of 10 or less

Keep it there during exercise and the rest of your day, settled by the next morning. Move on when one single-leg squat hurts 3 or less after at least a week at the current stage. That's stricter than the general rule for knee pain.

Source 4

No loading type clearly wins

Heavy and moderate slow lifting did equally well, so did one and three days a week, and a 2026 network meta-analysis found nothing clearly better than heavy slow resistance. The trials conflict on whether holds ease pain more than lifting.

Sources 5, 6, 7, 8

Change a few Pilates moves

Single-leg and decline squats and jumping loaded the tendon most in a lab study of rehab exercises. So jumping, including the reformer jumpboard, and deep loaded knee bends wait for the plan's later stages, and kneeling moves get padded or swapped (our reading).

Source 9

Hips and trunk belong alongside, not instead

Weaker hips go with the condition, and the largest trial gave hip and core exercises to everyone, but no trial has tested hip or trunk work as the treatment.

What patellar tendinopathy is

Pain at the bottom of the kneecapStrong evidence

Jumper's knee is pain at the lower tip of the kneecap, where the patellar tendon starts, that rises with load on the thigh muscles, especially jumping and landing. Diagnosis is clinical, because scans can show tendon changes in people without pain. Tendinopathy is the preferred term for persistent tendon pain linked to load; most people search for tendonitis, and the NHS knee pain page uses that word.

Sources 12, 13, 14

Look-alikesEmerging evidence

Pain at the top of the kneecap is quadriceps tendinopathy, and in children who are still growing, pain at the bottom of the kneecap is usually Sinding-Larsen-Johansson disease. Both have their own guides.

Sources 15, 16

Who gets itStrong evidence

Across 28 studies, 18.3% of athletes had it against 0.1% of the general population, with volleyball (24.8%) and basketball (20.8%) highest. In Norwegian elite athletes, 14.2% had it, 44.6% of volleyball players; in Dutch non-elite athletes, 8.5%. In junior singles figure skaters, 14.9% of girls and 16.1% of boys.

Sources 17, 18, 19, 20

Load is the risk you can changeEmerging evidence

In 141 young elite volleyball players, each extra weekly training hour and each extra set of matches a week raised the odds, and jump counts may matter more than total training time. A systematic review found no strong or moderate evidence for any single risk factor.

Sources 21, 22, 23

How long it lastsEmerging evidence

Symptoms had lasted 32 months on average in Norwegian elite athletes. Fifteen years on, 9 of 17 former athletes with jumper's knee had stopped their sport because of the knee. Five years after the largest trial, 76% felt recovered and 71% were back in their sport, but almost a quarter weren't recovered.

Sources 18, 24, 25

What the evidence says

No trial has tested Pilates for patellar tendinopathy. Progressive tendon loading carries the evidence, at low certainty overall, and a Dutch guideline puts exercise first.

No Pilates trial: two single case reportsStrong evidence

Our searches of PubMed, Europe PMC and ClinicalTrials.gov on 1 November 2026, including all 107 registered patellar tendinopathy trials, found no Pilates, core or hip trial. In one 21-year-old professional basketball player, supervised reformer Pilates 3 times a week for 6 weeks, with springs set so pain stayed below 5 out of 10, went with his knee function score (VISA-P, 0 to 100) rising from 53 to 83; there was no comparison and no follow-up. An older Brazilian case report described one 16-year-old girl after rehabilitation, with no tendon-specific result.

Sources 1, 2, 3

Pilates in other knee painMixed evidence

In 34 adolescents with kneecap pain, adding Pilates-based core strengthening to physiotherapy for 3 months reduced pain more than physiotherapy alone, and in 36 young adults whose knees cave in, 6 weeks of Pilates improved knee alignment in a drop jump. A Turkish trial of Pilates for kneecap pain finished in 2023 with no results posted. None of these was tendinopathy; our Pilates for knee pain guide covers them.

Sources 26, 27, 28

The largest trial: staged loadingEmerging evidence

In 76 athletes in the Netherlands, a staged programme (holds, then slow strength, then springy jumping, then sport, each within pain of 3 out of 10 or less) beat painful eccentric decline squats at 24 weeks: the knee score improved by 28 points against 18. Return to sport at the previous level was 43% against 27%, not a clear difference, and only 40% to 49% stuck to the programme. Both groups also did flexibility, hip, calf and core exercises, and cut activities that caused considerable pain for about 4 weeks; the fastest return possible was after 4 weeks.

Source 4

Heavy or moderate, once or three times a weekEmerging evidence

Heavy slow resistance (squats, leg press and hack squats 3 times a week) kept its gains at 6 months, as did eccentric training, while the gains from a steroid injection faded. Heavy and moderate loads at the same volume gave the same results to a year; one exercise day a week did as well as three in 52 people; and light loads with blood-flow restriction matched heavy slow resistance in 36 men.

Sources 29, 5, 6, 30

Isometric holds: the trials conflictMixed evidence

One session of holds cut decline-squat pain from 7.0 to 0.17 out of 10 in 6 volleyball players, and holds gave more immediate relief than lifting in 20 in-season athletes. But in 29 in-season athletes both kinds reduced pain equally, and in a preregistered crossover in 21 people, pain fell only 0.9 out of 10 after either. A review found holds weren't better than lifting for tendinopathy, and a 2026 UK Defence consensus called them equally effective for short-term pain. Holds help some people and are easy in season; they're the plan's first stage, not the whole treatment.

Sources 31, 32, 33, 8, 34, 35

Eccentric decline squatsMixed evidence

Decline squats in season did nothing for elite volleyball players who kept playing. A 2021 network meta-analysis still called eccentric loading the first choice, on low or very low certainty, but two 2026 analyses found no exercise clearly better than heavy slow resistance, with a small signal for staged loading.

Sources 36, 37, 7, 38

A Cochrane review and a guidelineStrong evidence

A 2025 Cochrane review found only 7 trials (211 athletes) comparing exercise with no treatment, injections, surgery or other care, all at very low to low certainty, and no trial measured side effects; exercise and surgery gave a similar return to sport. The 2025 Dutch guideline, the first national one, recommends exercise therapy for 12 weeks as the first choice despite the low level of evidence, and advises against injections. A UK Defence consensus warns that steroid injections into the tendon have been linked with rupture.

Sources 39, 13, 35

PreventionMixed evidence

Across 11 studies, prevention programmes didn't significantly cut patellar tendinopathy; one youth programme that wasn't randomised halved new cases.

Sources 40, 41

What loads the tendon

A loading index of 35 exercisesEmerging evidence

In 20 healthy adults, the single-leg decline squat loaded the patellar tendon most, then a running cut, a single-leg jump and a single-leg forward hop; running, two-leg jumps and drop jumps, single-leg full squats, the Spanish squat, lunges and two-leg full squats sat in the middle; and a 20 cm step up, a two-leg squat to 60 degrees and a 20 cm step down loaded it least. Past about 60 degrees of knee bend, the force behind the kneecap rises more than the force in the tendon. The study tested no Pilates moves.

Sources 9, 42

What it means for a Pilates class

Our reading: lying, side-lying and all-fours Pilates should load the patellar tendon very little; standing squats, lunges and single-leg work load it more as the knee bends and the speed rises; and jumping, including the reformer jumpboard, loads it most.

Source 9

Hips, trunk and landingEmerging evidence

Athletes with patellar tendinopathy had 27% lower hip extensor strength and weaker hip abductors and outward rotators, and thigh strength is lower too. Landing with more forward trunk lean reduced tendon force in one lab session, and in one volleyball player, hip strengthening and landing retraining left him pain-free at 6 months. But a review of landing studies found no clear link with trunk or hip angles, and all those studies had a high risk of bias. Hip, trunk and calf work belongs alongside the tendon loading, not instead of it.

Sources 10, 11, 43, 44, 45, 46, 47

The pain rule

Our jumper's knee guide's ruleEmerging evidence

The largest patellar tendon trial kept exercise pain at 3 out of 10 or less, a lower ceiling than for joint pain. Keep the rest of your activity within the same limit, and expect the tendon to settle back to its usual level by the next morning.

The progress test from that trial: do one single-leg squat and rate the tendon pain. Move to the next stage when it is 3 or less and you have done at least a week at the current stage.

Source 4

Other trials used other limitsMixed evidence

The heavy slow resistance trial allowed sport up to 30 out of 100, and the reformer case kept pain below 5 out of 10. In Achilles tendinopathy, carrying on running and jumping with a pain-monitoring model did no harm.

Sources 29, 2, 48

In a Pilates class

Use the 3 out of 10 rule for tendon loading, standing work and anything springy; the lying and side-lying moves shouldn't bother the tendon at all. If the tendon is sorer the next morning, cut back the standing and loaded work first (our suggestion).

The reformer, footwork and the jumpboard

Footwork is a light leg pressEmerging evidence

Spring settings didn't predict the force on the footbar accurately in the one study that measured it, and the direction of the push changed which muscles did the work. Nobody has measured how much reformer footwork loads the patellar tendon.

Sources 49, 50

How to use it

Treat footwork as a light leg press within the 3 out of 10 rule, with a smaller knee bend at first, and tell your teacher about the tendon. Leave the jumpboard out until our jumper's knee guide's spring stage, then start with two legs on light springs (our suggestion). In the one reformer case, jumpboard work came after week 3, with pain kept below 5 out of 10.

Sources 2, 9

Pilates around the loading plan

From our jumper's knee guide's first stage, which follows the largest trial (Breda 2021); fitting a Pilates class around it is our suggestion, untested.

  1. For about 4 weeks, cut down jumping and anything that causes considerable tendon pain, and keep the rest of your activity within 3 out of 10.
  2. Every day, do the plan's first-stage hold: a Spanish squat, wall sit or leg extension, about 5 holds of 30 to 45 seconds at a hard-but-OK effort, with 1 to 2 minutes' rest.
  3. Add glute bridges and slow calf raises, 3 sets of 12 each, as the guide's first stage does.
  4. Two or three times a week, do the Pilates class around it: hip, trunk and balance work with no kneeling, shallow knee bends and no jumping.
  5. Rate the tendon during exercise and the next morning: keep it at 3 out of 10 or less, and back to its usual level by the next morning.
  6. After at least a week, do one single-leg squat. When it hurts 3 out of 10 or less, move on to the guide's slow strength stage.
  7. Leave jumping, including the reformer jumpboard, until the guide's spring stage.

See the movement on the 3D figure: Spanish squat (band squat hold)

The loading plan's first stage

Spanish squat, 4 to 5 holds of 30 to 45 seconds at a hard-but-OK effort, with 1 to 2 minutes' rest, once a day in the isometric stage (the move page's dose); wall sit, 5 holds of 30 to 45 seconds (our jumper's knee guide, stage 1), an untested home option, as the guide says; leg extension, 5 holds of 30 to 45 seconds with about 2 minutes' rest, the knee bent about 60 degrees (our jumper's knee guide, stage 1), if you have a gym; glute bridge, 3 sets of 12 (our jumper's knee guide, stage 1); slow calf raise, 3 sets of 12 (our jumper's knee guide, stage 1).

Hips, light on the knee

Side kick, 8 to 10 each side (the move page's dose), with the bottom knee bent; clamshell, 10 each side (our Pilates for knee pain class); side-lying leg raise, 8 each side, heel leading (our Pilates for knee pain class); shoulder bridge, 3 to 5 kicks each leg (the move page's dose), once the glute bridge is comfortable; wall bridge, 8 to 10 reps; one-leg version, 5 each side (the move page's dose).

Trunk, knees kept shallow

Hundred, 50 beats to start, building to 100 (the move page's dose), knees bent in a tabletop; single-leg stretch, 6 each side with your hands behind the thigh (our Pilates for knee pain class); dead bug, 6 each side (our Pilates for tennis players class); knee side plank, 2 holds of 20 seconds each side (our Pilates for tennis players class), or on your forearm and feet if kneeling presses on the tendon (our suggestion).

The back of the body and balance

Swimming, 2 sets of 20 seconds (our Pilates for basketball players class), with a folded towel under your thighs if your kneecap presses on the mat; single-leg stand, 2 holds of 20 seconds each leg (our Pilates for knee pain class); hip airplane, 2 sets of 5 slow turns each leg (the move page's dose), with the standing knee only slightly bent.

What to change or leave out

Jumping, including the reformer jumpboard

Leave it out until our jumper's knee guide's spring stage, then start with two-leg jumps on light springs (our suggestion, from the staged plan and the loading index).

Sources 4, 9

Deep loaded knee bends

Keep squats, lunges, step-downs and reformer footwork in a shallower range at first and within 3 out of 10. Deep bends past about 60 degrees load the kneecap joint more, and single-leg and decline squats load the tendon most. The leg extension's page already says to start light and work from about 90 to 45 degrees of bend if the kneecap complains.

Sources 42, 9

Kneeling

Pad the knees or swap to lying and standing versions of the knee hover, kneeling side kick and bird dog, as our Pilates for knee pain guide says; the kneeling side kick's page says to avoid it with knee problems and pad the kneeling knee.

The single-leg kick and rocking

Kick through a smaller range in the single-leg kick if deep knee bending hurts the kneecap, as its page says; rocking's page says to avoid it with back or knee injuries.

Decline squats and painful eccentric work in season

Not in a Pilates class: in-season decline squats did nothing for players who kept playing, and painful eccentric training did worse than staged loading.

Sources 36, 4

Stretching instead of loading

In the largest trial, flexibility exercises were an add-on in both groups, not the treatment being tested. Keep stretches short and comfortable, and keep the loading going.

Source 4

Children with pain at the bottom of the kneecap

This is usually Sinding-Larsen-Johansson disease, not tendinopathy: see its guide.

Source 16

Classes to follow

Our 25-minute tendon-friendly class builds in the first stage of the jumper's knee guide's loading plan, with hip, trunk and calf work, no kneeling, no deep knee bends and no jumping. The tendon strengthening workout is the gym-style version of the loading; the knee pain classes suit other knee problems.

When to stop and get help

This is general information, not a diagnosis. A&E means accident and emergency; in the US, call 911 for 999, and use your doctor's urgent line or urgent care for NHS 111.

A sudden pop below the kneecap

A sudden pop at the front of the knee, after which you cannot straighten the knee or lift the straight leg. This can be a torn patellar tendon: see our torn kneecap tendons guide.

Same day: a pop or tearing feeling at the front of the knee after a fall, stumble, jump or landing, then you can't straighten the knee or lift the straight leg off the bed, there's a dent above or below the kneecap, or the kneecap sits higher or lower than on the other side. Go to A&E or an urgent treatment centre, or get help from NHS 111. A torn quadriceps or patellar tendon does best when it's repaired soon.

Sources 51, 14

A child or teenager

A child or teenager: after a jump, landing or fall, a pop or sudden severe pain below the kneecap, and the knee will not straighten or take weight. Get it checked the same day: the bony bump below the kneecap can break away instead of the tendon tearing, or a sleeve of bone and cartilage can pull off the lower kneecap.

Sources 51, 16

A hot, swollen knee

Get advice from NHS 111 now: a hot, red or swollen knee with sudden severe pain, a very high temperature (although not everyone has one), or feeling hot, cold or shivery. This can be a joint infection.

Sources 14, 52

Other urgent knee signs

Get advice from NHS 111 now: you cannot move the knee or put any weight on it, or it is very painful, badly swollen or has changed shape.

You hurt your knee and cannot take 4 steps, or you are 55 or over and have injured it: get it checked the same day for a broken bone.

See a doctor or physiotherapist if

Knee pain that has not improved within a few weeks of looking after it at home. Many areas offer NHS physiotherapy without a GP referral.

During Pilates: the pain rule

The largest patellar tendon trial kept exercise pain at 3 out of 10 or less, a lower ceiling than for joint pain. Keep the rest of your activity within the same limit, and expect the tendon to settle back to its usual level by the next morning.

Source 4

What to cut back while it settles

For about 4 weeks, cut down the activities that cause considerable tendon pain, jumping volume especially. Keep the rest of your activity within 3 out of 10.

Chest pain or fainting: call 999

Call 999 if:

  • You get sudden pain or discomfort in your chest that doesn't go away; it can feel like squeezing or pressure, burning or indigestion.
  • The pain spreads to your left or right arm, or your neck, jaw, stomach or back.
  • You have chest pain and feel sweaty, sick, light-headed or short of breath.
  • Someone faints while exercising, can't be woken within 1 minute, or has chest pain or a pounding, fluttering or irregular heartbeat.

Sources 53, 54

Unusual breathlessness

Call 999 or go to A&E (accident and emergency) straight away for severe difficulty breathing (gasping, choking or not able to get words out), a chest that feels tight or heavy, pain that spreads to your arms, back, neck and jaw, lips or skin turning very pale, blue or grey, or sudden confusion. If you're more short of breath than usual, or your heart is racing, fluttering or skipping beats, contact NHS 111.

Source 55

Stop the session if

You feel any pain or become unwell, as the NHS advises for its Pilates videos, and especially for chest pain or pressure, unusual breathlessness, dizziness or fainting. If you have a health problem, an injury or any symptoms, get advice from a healthcare professional, such as a GP, before you start.

Before you start

The NHS advises getting advice from a healthcare professional first if you have a health problem, an injury or symptoms, or have recently had a heart attack or an operation.

Myths

"Rest cures jumper's knee"Emerging evidence

The treatment that works is loading the tendon in stages, and the trials ran 12 to 24 weeks; in season, the approach is cutting jumping while loading the tendon. Rest alone hasn't been tested as a treatment, symptoms often last months to years, and exercise beat no treatment for pain in one small trial, at very low certainty.

Sources 4, 29, 18, 39

"Pilates heals patellar tendonitis"Strong evidence

No trial has tested Pilates for patellar tendinopathy; there are two single case reports, one in a basketball player. The loading plan is the treatment, and Pilates is the session around it.

Sources 1, 2, 3

"It's tendonitis, so stretch the quads and ice it"Mixed evidence

Tendinopathy is the preferred name for persistent tendon pain linked to load. In the largest trial, flexibility exercises for the thigh and calf muscles were an add-on in both groups, not the treatment being tested; the plan is load, not stretch.

Sources 13, 4

"Pain means stop all exercise"Emerging evidence

The largest trial kept exercise pain at 3 out of 10 or less and loaded the tendon throughout, as our jumper's knee guide does.

Source 4

"Squats are bad for jumper's knee"Mixed evidence

Squats and leg presses done slowly within the pain rule are treatment (heavy slow resistance). It's deep, fast or jumping loads in the early weeks that need cutting back.

Sources 29, 4

"Reformer footwork is perfect jumper's knee rehab"Mixed evidence

Footwork works the thigh against springs, but no study has measured how much it loads the patellar tendon, and spring settings didn't predict footbar force accurately in the one study that measured it. Treat it as a light leg press within the pain rule.

Source 49

"You need a reformer for real Pilates"Mixed evidence

In the one trial that compared them in athletes (footballers), both mat and reformer Pilates improved tests, the reformer slightly more on three. Use what you can get to, within the pain rule.

Source 57

Questions people ask

Is Pilates good for patellar tendonitis?

Pilates hasn't been tested for it: there are two single case reports and no trial. What treats it is loading the tendon in stages; Pilates is a good way to keep training around that, with the loading plan's first-stage hold built in.

Can I do Pilates with jumper's knee?

Yes. Lying and side-lying Pilates should put little load on the patellar tendon, since squats and jumps loaded it most in a study of rehab exercises (our reading). Keep tendon pain at 3 out of 10 or less, settled by the next morning, leave out jumping and deep loaded knee bends for now, and pad or swap kneeling moves.

Is reformer Pilates good for patellar tendonitis?

It can be, with care. Footwork is a light leg press, so use lighter springs, a smaller range and the 3 out of 10 rule; nobody has measured how much it loads the tendon, and spring settings don't predict footbar force accurately. The jumpboard waits for the plan's spring stage.

Which Pilates moves should I avoid with patellar tendonitis?

For now: the jumpboard and any jumping, deep squats and lunges under load, deep single-leg bends, and long kneeling. Single-leg and decline squats and jumps load the tendon most.

Which Pilates exercises help jumper's knee?

Bridges, side kicks, clams and side-lying leg raises for the hips, the hundred and dead bug for the trunk, and calf raises; the largest trial gave hip, calf and core exercises to everyone alongside the loading. Add the plan's daily hold, such as a wall sit or Spanish squat.

Do isometric holds help?

They ease pain for a while in some people and are easy to do in season, but the trials conflict and they haven't been reliably better than slow lifting. They're the first stage of our jumper's knee guide's plan, not the whole treatment.

Should I rest jumper's knee completely?

No. Cut down jumping and anything that hurts a lot for about 4 weeks, and keep loading the tendon within the pain rule; symptoms often last months or years without it. The Dutch guideline puts exercise first for 12 weeks.

How much pain is OK in Pilates with jumper's knee?

Keep tendon pain at 3 out of 10 or less during exercise and the rest of your day, back to its usual level by the next morning, as the largest trial did. Move on when one single-leg squat hurts 3 out of 10 or less and you've done at least a week at the current stage.

How long does patellar tendinopathy take to get better?

The trials ran 12 to 24 weeks, the quickest return in the largest trial's programme was 4 weeks, and 5 years later 76% felt recovered. Many people need months; keep the strength work going after you're back.

Do steroid injections help jumper's knee?

In one trial an injection helped at first, but the gains faded by 6 months while those from exercise held. The Dutch guideline advises against injections, and steroid injections into the tendon have been linked with rupture.

Is it patellar tendonitis or tendinopathy?

Both names describe the same problem. Tendinopathy is the preferred term in current guidelines, for persistent tendon pain and loss of function linked to load. Pain at the top of the kneecap is quadriceps tendinopathy, and in children, pain at the bottom of the kneecap is usually Sinding-Larsen-Johansson disease.

When should I see a doctor about knee tendon pain?

The same day for a sudden pop below the kneecap with a knee you can't straighten, and urgently for a hot, swollen knee with a fever. See a GP or physiotherapist if it hasn't improved within a few weeks of looking after it at home.
