We research products from makers' specs and health sources; we do not run hands-on tests. Links to Amazon may earn us a commission at no cost to you. How this works.
- Adjustable patellar tendon strap. Best for: Pain below the kneecap during running, jumping or squats. See options on Amazon
- Dual knee strap, above and below the kneecap. Best for: People whose single strap keeps sliding down. See options on Amazon
- Knee sleeve with silicone kneecap pad. Best for: Front-of-knee aches when you also want general compression. See options on Amazon
- Resistance band loop for isometric holds. Best for: The early isometric exercises in an NHS-style rehab plan. See options on Amazon
What patellar tendinopathy is
The patellar tendon links the kneecap to the shin bone. An NHS physiotherapy leaflet from Kingston and Richmond explains that tendinopathy means the tendon is injured because it cannot cope with the load placed on it. Contributing factors it lists include lots of running or jumping, a sudden increase in training, weak knee or hip muscles, being overweight and reduced ankle movement.
Typical signs: pain over the tendon just below the kneecap, pain that builds gradually, stiffness after rest, and pain after strenuous activity such as running or jumping.
Brace options compared
| Type | How it works | Best for | Trade-off |
|---|---|---|---|
| Patellar tendon strap | Narrow band presses on the tendon below the kneecap | Pain during jumping, running, squats | Must sit in exactly the right spot |
| Dual strap (above and below kneecap) | Two bands frame the kneecap | People who find a single strap slips | Bulkier |
| Knee sleeve with kneecap pad | Compression plus a shaped pad | All-round support, front-of-knee aches | Less focused on the tendon |
| Kinesiology tape | Tape applied over or around the tendon | Sport, if you know the method | Skill needed; skin irritation possible |
Mayo Clinic says strapping or taping can help take pressure off the patellar tendon. Mueller describes its jumper's knee strap as an adjustable tube that applies mild pressure below the kneecap. Cleveland Clinic includes patellar tendinitis among the conditions braces may be used for.
How to fit a patellar tendon strap
- Find the tendon. Sit with the knee bent. The tendon is the firm band between the bottom of the kneecap and the bump on the shin.
- Place the strap. Center the strap's pad over the tendon, just below the kneecap, not on the kneecap itself.
- Check the size. Mueller's jumper's knee strap is one size, fitting knees that measure 10 to 22 inches (25 to 55 cm) around. Measure if you are near either end.
- Tighten for activity only. Snug enough to feel pressure on the tendon, never enough to cause tingling or color change below.
- Recheck during sport. Straps can slide down the shin. Reposition between sets or periods.
The part that does the work: loading the tendon
The Kingston and Richmond leaflet lays out a staged plan your physiotherapist adapts:
- Isometric holds first. Straightening the knee against a resistance band, then wall sits, held for 15 to 45 seconds, repeated 3 to 5 times, 3 times a day.
- Then squats. 8 to 15 repetitions for 3 sets, with 1 minute rest, once a day, progressing to single-leg squats.
- Progress by symptoms. Move to the next phase when pain or discomfort settles within 24 hours, and stop an exercise that significantly increases pain.
Mayo Clinic also lists regular stretching of the thigh muscles and strengthening that gradually increases load on the tendon, plus ice after painful activity and reducing or switching away from sports that aggravate it.
Common mistakes
- Wearing the strap on the kneecap, where it presses the wrong structure.
- Using the strap to keep jumping through rising pain instead of reducing load.
- Wearing it all day. A strap is for the activity that hurts.
- Skipping the strengthening, which both Mayo Clinic and the NHS leaflet put at the center of care.
If your pain is around or behind the kneecap rather than below it, see our patellofemoral knee brace guide.
What to look for when you buy
Adjustable patellar tendon strap
Best for: Pain below the kneecap during running, jumping or squats
Concentrates pressure on the tendon. Mayo Clinic lists strapping as a way to take pressure off the patellar tendon.
Watch out: Only helps if it sits on the tendon. One size may not fit very small or large knees.
See options on AmazonDual knee strap, above and below the kneecap
Best for: People whose single strap keeps sliding down
Two linked bands hold each other in place and frame the kneecap.
Watch out: Bulkier and warmer than a single strap.
See options on AmazonKnee sleeve with silicone kneecap pad
Best for: Front-of-knee aches when you also want general compression
Cleveland Clinic includes patellar tendinitis among the conditions knee supports may be used for, and a sleeve adds general compression.
Watch out: Less targeted than a strap for pain right on the tendon.
See options on AmazonResistance band loop for isometric holds
Best for: The early isometric exercises in an NHS-style rehab plan
The NHS leaflet's first phase uses a band to hold the knee straight for 15 to 45 seconds.
Watch out: Let your physiotherapist set the starting phase.
See options on AmazonQuestions people ask
- Do patellar tendon straps work?
- They may ease pain during activity. Mayo Clinic says strapping or taping can help take pressure off the patellar tendon, but strengthening is the main treatment.
- Where should a patellar tendon strap go?
- Just below the kneecap, with the pad over the tendon, not on the kneecap itself.
- Should I wear a knee strap all day for jumper's knee?
- Usually no. Wear it for the activity that provokes pain and take it off afterward.
- How long does patellar tendinopathy take to get better?
- It varies. The NHS leaflet moves you through stages as pain settles within 24 hours after exercise, and your physiotherapist sets the pace.
- Is patellar tendonitis the same as jumper's knee?
- Yes, both names describe pain in the tendon below the kneecap. Many clinicians now say tendinopathy.
