Patellar Tendinopathy
Patellar tendinopathy—often called jumper’s knee—is a load-related tendon problem. The classic presentation is focal pain at the lower edge of the kneecap during jumping, landing, acceleration or heavy knee-extension work. The diagnosis is made from that pattern and the examination, not from an abnormal scan alone.
The first job is to distinguish it from patellofemoral pain, fat-pad irritation, referred pain and a partial patellar tendon tear. Sudden pain with a pop, rapid swelling, loss of strength or inability to straighten the knee needs prompt assessment rather than a routine tendinopathy program.
Treatment starts with progressive loading
Exercise therapy is first line. The sequence usually begins with a tolerable way to load the quadriceps and tendon, then progresses strength through range, and finally restores the faster energy-storage demands of running, jumping, landing and change of direction. Complete rest can settle symptoms temporarily but does not prepare the tendon for sport.
A 2024 multidisciplinary guideline for patellar tendinopathy recommends exercise therapy first and reserves additional conservative treatments for cases without clinically relevant improvement after an adequate loading trial. Imaging has limited additional value in a typical presentation.
Shockwave or other procedures are adjuncts, not replacements for rehabilitation. If pain has persisted despite a well-structured program, the diagnosis, training dose and exercise progression should be reviewed before another treatment is added.
Common symptoms
- Focal pain at the lower edge of the kneecap or in the patellar tendon
- Pain with jumping, landing, sprinting, squatting or stairs
- Pain that may warm up during activity and return afterwards
- Local tenderness rather than diffuse pain around the kneecap

Evidence for twelve treatment options in patellar tendinopathy
This is not a fixed ladder or a package of treatments. Every option is assessed independently against this diagnosis, including treatments with limited direct research that may still be reasonable for a clearly defined tissue target. The evidence level, likely benefit, risks, cost and alternatives are weighed at consultation.
Foundation — diagnosis, education and rehabilitation
The part of care with the broadest relevance. For many people it is enough on its own; other options are judged against it, not automatically added after it.
Diagnosis, education and progressive rehabilitation Working out what is driving the pain, explaining what your imaging does and does not mean, and building a graded loading plan you can actually follow. Core care
What it involves
Assessment to identify the likely pain source, an explanation of what the diagnosis means, adjustment of the loads that aggravate it, and a progressive strength and conditioning plan — with weight management where that is clinically relevant.
What the evidence shows
Loading is the treatment, and the trials say adjuncts add little to it. A living network meta-analysis of 68 randomised trials across Achilles and patellar tendinopathy and gluteal tendinopathy found no convincing evidence that any adjunct, alone or added to exercise, beats exercise by itself — and recommended exercise alone for at least three months before an adjunct is considered (Challoumas, Sports Med Open 2023). A meta-analysis of 110 studies and 3,953 patients found greater effect where the programme added external load rather than body weight alone, and where sessions were less frequent than daily, allowing recovery (Pavlova, Br J Sports Med 2023). A 204-study synthesis found exercise safe, beneficial and acceptable to patients, with no clear superiority for the eccentric-only protocols long treated as standard (Cooper, Health Technol Assess 2023).
Pairing reviewed 2026-09-02.
Where it fits for you
This is the plan, not the preliminary. Expect a programme measured in months rather than weeks, with load progressed against your symptoms. Anything else offered here is an adjunct to it, and the evidence for adding one before three months of proper loading is weak.
Muscle and symptom-modifying options
Useful only when the examination identifies the tissue they target or when short-term pain control creates a useful rehabilitation window.
Wet needling and trigger point injection (trigger point injection) A fine needle into a tender band of muscle, with a small volume of dilute glucose solution injected through it. Only if relevant
What it involves
The needle is placed into the tender muscle band and a small volume of 5% glucose with 0.02-0.08% lignocaine is injected. Often done in the same visit as your assessment, and usable where the tender area sits deeper. Dry needling — the same technique with nothing injected — is not offered here.
What the evidence shows
Trigger-point injection reviews address confirmed myofascial pain and find heterogeneous, generally low-certainty results; they do not establish the technique as treatment for the underlying diagnosis. Condition reviewed: patellar tendinopathy.
Evidence source: Debrosse et al., trigger-point injection systematic review (2022)
Pairing reviewed 2026-08-30.
Where it fits for you
For patellar tendinopathy, this may be considered only when examination finds a separate tender muscle band reproducing part of the pain. It does not treat the primary pathology and is used to help movement or rehabilitation.
Ultrasound-guided injections Guidance means we can see the needle reach the target. What goes into the needle depends on the diagnosis. Plausible — no studies
What it involves
The injection is performed under ultrasound so the needle can be watched into the target structure. What is injected is decided by the diagnosis — and corticosteroid is used sparingly, for the reasons set out below.
What the evidence shows
No trial has compared guided with unguided injection at this site. The general finding is that guidance improves accuracy everywhere but only improves outcomes where the target is small or deep (Aly, Br J Sports Med 2014; Fan, Arthroscopy 2021).
Pairing reviewed 2026-08-30.
Where it fits for you
Injection is not first-line for this problem. Where one is indicated and the target is small, guidance is used.
V-ACTOR vibration therapy (vibration therapy) Low-frequency vibration applied over tender muscle. Not a shockwave, despite sharing the machine. Plausible — no studies
What it involves
A vibration handpiece is moved over the tender muscle and fascia for a few minutes. It runs from the same STORZ MASTERPULS icon console as radial shockwave but is a separate handpiece delivering a different, gentler form of energy. No needles, no anaesthetic, no downtime.
What the evidence shows
No published clinical trial of this device in this condition. It is a vibration handpiece delivered from the same console as radial shockwave, and the rationale is myofascial rather than tendon- or bone-directed.
Pairing reviewed 2026-08-30.
Where it fits for you
A comfort measure used within a session where muscular tightness is limiting movement. Never the reason for the appointment, and not a substitute for the treatments that do have evidence.
Energy-based treatment options
Radial pressure wave, focused shockwave and EMTT have different targets and different evidence. They are assessed separately rather than treated as one category.
Radial or focused shockwave? Read the overviewRadial shockwave (radial pressure wave) Broad treatment across tender muscle and fascia, close to the surface. Evidence mixed
What it involves
A handpiece is moved over the tender tissue while ballistic pressure pulses are delivered, using a transmitter head chosen for the tissue — including heads shaped for fascia and for the muscle either side of the spine. The pulse is strongest at the skin and weakens with depth, so this is mainly a myofascial treatment, though it can reach deeper in some areas. No anaesthetic, no downtime, usually a course of sessions about a week apart.
What the evidence shows
Radial shockwave was null for both function and pain in a Level I network meta-analysis of patellar tendinopathy (Chen, Arthroscopy 2019).
Pairing reviewed 2026-08-30.
Where it fits for you
Eccentric and slow heavy loading is first-line here and shockwave has not been shown to add to it.
Focused shockwave (ESWT) A true shock wave converging at depth — for tendon, joint, ligament and bone. Evidence mixed
What it involves
A focused system generates an acoustic shock wave that converges at a focal point set at a defined depth, concentrating the energy where the target is. This is the form we use for tendon, joint, ligament and bone. Typically four to six sessions about a week apart, no anaesthetic and no formal downtime.
What the evidence shows
Three independent syntheses agree it does not add to loading. A Level I network meta-analysis found focused shockwave null for both function (VISA change -1.28, 95% CI -6.25 to 3.68) and pain, with radial no better (Chen, Arthroscopy 2019). A living network meta-analysis found moderate-strength evidence that adding shockwave to eccentric exercise gives no short-term benefit (Challoumas, Sports Med Open 2023).
Pairing reviewed 2026-08-30.
Where it fits for you
Eccentric and slow heavy loading is first-line and shockwave has not been shown to add to it. Discussed only where a proper loading programme has been done and has stalled.
EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Painless, no contact. Plausible — no studies
What it involves
You sit with the applicator positioned over the area for a short session. Painless, no gel or contact required, and usually delivered as a course — commonly alongside shockwave.
What the evidence shows
There are no published randomised trials of EMTT in this condition, or in any musculoskeletal condition, that we can point to. The supporting work is laboratory work: EMTT increased tenocyte proliferation, migration and collagen expression in cultured human tendon cells (Mancini, Int J Mol Sci 2025). The nearest human evidence for a related electromagnetic therapy is negative — a randomised trial of pulsed electromagnetic field therapy added to eccentric exercise for Achilles tendinopathy found no improvement in outcome scores or tendon neovascularity over eccentric exercise alone (Ko, Orthop J Sports Med 2024).
Pairing reviewed 2026-08-30.
Where it fits for you
Offered only as an adjunct alongside treatment that does have evidence, never as the plan itself, and only after that gap is explained. Much of the EMTT literature is manufacturer-affiliated, which is part of why we describe it this way.
Biologic and joint injection options
Each injection is assessed independently for the named diagnosis. Cost, uncertainty, likely benefit, risks and alternatives are part of the decision.
Platelet-rich plasma (PRP) Your own blood, concentrated and injected under ultrasound guidance. Good support
What it involves
Blood is taken from your arm, spun to concentrate the platelets, and injected into the target under ultrasound guidance in the same appointment.
What the evidence shows
Leukocyte-rich PRP ranked best of nine non-surgical options for both functional improvement and pain reduction in a Level I network meta-analysis (Chen, Arthroscopy 2019). A separate meta-analysis of 70 studies found eccentric exercise best in the short term but MULTIPLE PRP injections best at long-term follow-up, ahead of both shockwave and eccentric exercise (Andriolo, Am J Sports Med 2019).
Pairing reviewed 2026-08-30.
Where it fits for you
Where a proper loading programme has stalled, this has better evidence than shockwave for this particular tendon. Multiple injections rather than one.
Prolotherapy (dextrose) A course of dextrose injections into and around the structure and its attachments. Plausible — no studies
What it involves
Hypertonic dextrose is injected at the tender ligament and tendon attachments, and into the joint where relevant, usually as a series of treatments a few weeks apart.
What the evidence shows
No randomised trial of prolotherapy in this condition. The evidence base sits in lateral epicondylitis, rotator cuff tendinopathy, plantar fasciitis and knee osteoarthritis (Capotosto, Orthop J Sports Med 2024). A network meta-analysis of 87 trials across chronic soft-tissue injury found prolotherapy had no statistically significant pain advantage over other therapies overall, though its effect size was consistently better than non-injection treatment and corticosteroid (Goh, PLoS One 2021).
Pairing reviewed 2026-08-30.
Where it fits for you
Can be discussed on the same rationale as the studied tendon and ligament problems, with the absence of direct trials stated plainly.
Viscosupplementation (hyaluronic acid) A gel-like injection into an arthritic joint. Widely used, and genuinely contested. Plausible — no studies
What it involves
One or a short series of hyaluronic acid injections into the joint under ultrasound guidance.
What the evidence shows
A meta-analysis of 19 randomised trials found hyaluronic acid produced short and mid-term pain benefit across several soft-tissue indications including rotator cuff, elbow, ankle sprain, Achilles and patellar tendinopathy — but with very high heterogeneity, mostly single trials per indication, and uncertain benefit for trigger finger (Khan, Sports Health 2022).
Pairing reviewed 2026-08-30.
Where it fits for you
Not a routine option outside the knee. Mentioned where someone asks about it, with the weakness of the data stated.
Nerve-targeted options
Relevant when examination identifies a superficial neuropathic pattern or a compressed peripheral nerve—not simply because pain is present.
Lyftogt perineural therapy (perineural injection therapy) A series of small dilute dextrose injections just under the skin, over tender superficial nerves. Only if relevant
What it involves
Small injections of low-concentration dextrose, usually 5%, placed just beneath the skin along tender superficial nerves. Given as a series of short sessions.
What the evidence shows
Perineural dextrose evidence is concentrated in diagnosed peripheral compression neuropathies, particularly the upper limb; no direct evidence was identified for this diagnosis itself. Condition reviewed: patellar tendinopathy.
Evidence source: Perineural dextrose for upper-limb entrapment neuropathy review (2025)
Pairing reviewed 2026-08-30.
Where it fits for you
For patellar tendinopathy, perineural treatment may be considered only if a separate superficial neuropathic pain pattern is found on examination. It is not treatment of the primary diagnosis.
Ultrasound-guided nerve hydrodissection Fluid placed around a nerve to free it from the surrounding tissue. Only if relevant
What it involves
Under ultrasound, fluid is placed in the plane around the nerve to separate it from the tissue that is tethering or compressing it.
What the evidence shows
Hydrodissection evidence is concentrated in ultrasound-confirmed peripheral nerve entrapment, especially carpal tunnel syndrome; no direct evidence was identified for this diagnosis itself. Condition reviewed: patellar tendinopathy.
Evidence source: Buntragulpoontawee et al., hydrodissection injectate review (2021)
Pairing reviewed 2026-08-30.
Where it fits for you
For patellar tendinopathy, hydrodissection may be considered only if ultrasound and examination identify a separate compressed or tethered peripheral nerve. It is not treatment of the primary diagnosis.
This is general information only and suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of the uncertainty, the expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
Every treatment above is described in full on the non-surgical treatments page, including what each one is used for and what the evidence supports. Ratings apply to the named diagnosis; an adjacent muscle, tendon, joint or nerve problem is assessed as a separate target.
Corticosteroid injection is reviewed separately for each diagnosis.
Cortisone reliably reduces pain in the short term, and that can be genuinely useful when pain is stopping you sleeping or moving enough to rehabilitate. Beyond that window the picture changes. Evidence in tendon problems suggests early relief can be followed by worse outcomes at a year than exercise alone, and repeated injections into a joint have been associated with cartilage loss. It does not repair anything.
So we do not build treatment plans around it. Where an injection is the right call, we review the specific diagnosis and target, discuss what is being injected and why, keep the number low, and pair it with the loading work that changes the longer-term course.
When we would still consider it
- Pain severe enough to block rehabilitation
- A clear inflammatory or bursal target on imaging
- A specific short-term goal — a trip, a procedure, a return to work
- Diagnostic use, where the response tells us where the pain is coming from
When a cortisone injection is worth doing, and when it is not
Other knee conditions
Pain in the same area can come from more than one source, and the label matters less than what the examination and history point to. These are the other guides for this region.
