Quick answer (60 sec read) Patellar tendinopathy ("jumper's knee") is sharp pain just below the kneecap, worse with jumping, deep squatting, and descending stairs. It's a tendon-capacity problem, not a tear. Management centres on progressive loading (isometric → heavy slow resistance → energy storage) — typically 8–12 weeks for symptom change, 4–6 months for full return to jumping and cutting sport. Most patients keep training in modified form throughout. AHPRA OST0004003860 · Educational content, not medical advice.

Is this runner's knee or patellar tendinopathy? Both cause anterior knee pain but they're distinct:

Patellar tendinopathy — localised pain at the tendon below the kneecap; worse with jumping, squatting, descending stairs. The painful spot is one specific point.
Runner's knee (patellofemoral pain) — diffuse pain *around* or *behind* the kneecap; worse with running, prolonged sitting, descending stairs. Hard to point to one spot.

If your pain is sharp and pinpoint just below the kneecap → keep reading. If your pain is diffuse and worsens with running → see runner's knee →.

Patellar tendinopathy (jumper's knee) — assessment and management

Patellar tendinopathy — often called "jumper's knee" — is anterior knee pain at the patellar tendon, common in jumping, squatting, and change-of-direction sports. It responds to progressive loading and structured rehabilitation. Max sees patellar tendinopathy across all three Sydney clinics, particularly in weight-training, basketball, volleyball, tennis, and CrossFit athletes.

What patellar tendinopathy is

The patellar tendon connects the kneecap (patella) to the shinbone (tibia) and transmits the force of the quadriceps muscle through the knee. Tendinopathy here means the tendon has become painful and less able to handle the loads it usually does — particularly the high-load, fast-loading demands of jumping, squatting, and decelerating.

The painful spot is usually at the inferior pole of the patella — where the tendon attaches to the kneecap — but can also be at the tibial tuberosity end. As with other tendinopathies, the underlying process is structural and load-related rather than primarily inflammatory.

How it typically presents

Sharp or aching pain at the front of the knee, just below the kneecap
Worse with jumping, deep squatting, descending stairs, or holding a sustained squat
Pain on palpation of the tendon at the lower edge of the patella
Often "warms up" at the start of activity and worsens later or the next day
Stiffness after sitting for a long time
Symptoms typically build over weeks, often after a change in training (more jumping, more volume, new programme)

How Max assesses patellar tendinopathy

Initial assessment covers:

History — sport and training load, onset, behaviour with activity, previous knee injuries
Examination — palpation of the patellar tendon, decline single-leg squat (a sensitive load test for patellar tendinopathy), step-down test, quadriceps and hip strength screening, hop test where indicated
Differential consideration — patellofemoral pain (different pain location and behaviour), fat pad irritation, Osgood-Schlatter or Sinding-Larsen-Johansson in adolescents, meniscal or ligament involvement if there are mechanical symptoms

Most patellar tendinopathy is a clinical diagnosis. Imaging is considered when the picture is unclear or symptoms haven't responded to a reasonable trial of loading.

How osteopathy may help — the management approach

The management framework mirrors other tendinopathies — progressive loading is the central principle.

Isometric quadriceps loading — holding a knee bend (Spanish squat, leg-extension hold) for pain modulation and early-stage adaptation
Heavy slow resistance — slow, loaded squats and leg-press work
Energy-storage loading — jumping, landing, cutting — reintroduced in stages

Alongside loading:

Manual osteopathic therapy — quadriceps, hip, and surrounding tissues
Activity modification — reducing aggravating volume rather than stopping the sport entirely where possible
Shockwave therapy (ESWT) — one option considered for selected patellar tendinopathy presentations
Strength work above and below — hip, glute, and calf strength all influence knee load
Imaging or referral — if the picture suggests something else

What a course of care typically looks like

Patellar tendinopathy is often slow to settle — meaningful change usually takes 8–12 weeks of consistent loading, and return to full jumping/cutting sport often runs to 4–6 months. A staged return-to-sport plan structures that final bridge.

Most patients can continue training through rehab at modified intensity. Max will work with you on what to modify (volume, depth, jumping frequency) rather than what to stop entirely.

When to see your GP or A&E instead

Most patellar tendinopathy is non-emergency. See your GP or A&E if:

You had a sudden, severe knee injury with significant swelling, an inability to weight-bear, or a feeling that the knee gave way — this may indicate a ligament, meniscal, or tendon rupture
Locking or catching of the knee suggests an internal joint problem
Numbness, tingling, or weakness in the leg suggests nerve involvement
Symptoms come with systemic signs (fever, night pain not related to activity, unexplained weight loss)

Frequently asked

Q. Should I stop jumping? Usually not entirely. Reducing the volume and intensity of jumping while loading the tendon progressively is more effective than stopping completely. Max will help you work out what's tolerable.

Q. Is "jumper's knee" the same as patellar tendinopathy? Yes. "Jumper's knee" is the common name; patellar tendinopathy is the clinical term.

Q. How long until I can train again? Most patients can keep training in a modified form throughout — the question is usually "what kind of training," not "should I stop." Return to full jumping and cutting sport often runs 4–6 months.
