Patellar tendinopathy — commonly called jumper's knee — is one of the most stubborn sports injuries a physiotherapist sees. Rest makes it feel better but doesn't fix it. The only thing that works long-term is the right loading program, applied at the right time.
What Is Patellar Tendinopathy?
The patellar tendon connects the patella (kneecap) to the tibia (shin bone) and is the primary transmitter of force from the quadriceps to the lower leg. When the tendon is repeatedly overloaded beyond its capacity to recover — as happens with jumping, sprinting, and rapid changes of direction — the tendon structure degenerates rather than adapts.
This is not a simple inflammation problem. Established tendinopathy involves structural changes within the tendon tissue: disorganised collagen fibres, increased tendon volume, and the ingrowth of new, pain-sensitive nerve and blood vessels. Anti-inflammatory treatments alone don't work because inflammation is not the primary driver.
Who Gets Patellar Tendinopathy?
Despite the nickname "jumper's knee," patellar tendinopathy affects anyone whose sport or activity involves repetitive high loads through the knee extensor mechanism. Common presentations include:
- Basketball and volleyball players (high jump load volume)
- AFL footballers
- Runners increasing mileage quickly
- Weightlifters with heavy squat programs
- Anyone returning to sport after a period of reduced activity
Symptoms and Diagnosis
Patellar tendinopathy typically presents as:
- Pain at the bottom pole of the patella (kneecap), often described as a sharp point of tenderness
- Pain that is worse with running, jumping, and squatting
- Pain that may be worse at the start of activity then eases, only to return after cooling down
- Morning stiffness and localised tenderness on palpation
Diagnosis is clinical — a physiotherapist can diagnose patellar tendinopathy from the history and physical examination alone. Ultrasound or MRI can confirm tendon changes but are rarely needed to guide treatment.
The Evidence-Based Treatment: Progressive Loading
The most robust evidence for patellar tendinopathy treatment supports heavy slow resistance (HSR) training — exercises that load the quadriceps and patellar tendon with high force at slow speed. This approach outperforms eccentric-only programs, cortisone injections, and PRP in long-term studies.
A typical rehabilitation program progresses through:
- Stage 1 — Isometric loading: Wall sits and isometric leg press for pain relief. Provides immediate analgesia and is suitable during reactive phases or before competition.
- Stage 2 — Isotonic loading: Heavy slow leg press and squat variations building to 80–85% of maximum load.
- Stage 3 — Energy storage: Gradual reintroduction of running, jumping, and change of direction.
- Stage 4 — Return to sport: Full sport-specific loading with objective testing criteria.
How Many Sessions Will I Need?
Physiotherapy appointments are used to monitor your progress, progress your loading program, and manage flare-ups. Most athletes need 6–10 sessions over 8–12 weeks, with daily home exercises carrying the bulk of the rehabilitation. Athletes with chronic (3+ months) tendinopathy may require a longer program.

Frequently Asked Questions
How long does patellar tendinopathy take to recover?
Mild cases improve in 6–8 weeks with a progressive loading program. Chronic or reactive tendinopathy can take 3–6 months. Skipping straight to rest and stretching — without progressive strengthening — is the most common reason recovery stalls.
Can I keep playing sport with patellar tendinopathy?
Depends on severity. A physiotherapist will use a simple pain-monitoring model: pain up to 5/10 during activity that returns to baseline within 24 hours is generally acceptable. Pain that spikes above that or takes more than 24 hours to settle indicates the load is too high.
Do I need a cortisone injection?
Cortisone injections are not recommended for patellar tendinopathy. Evidence shows they weaken tendon tissue and increase re-injury risk. Platelet-rich plasma (PRP) has more evidence but is still less effective than a well-executed heavy-load rehabilitation program.
What is the best exercise for patellar tendon pain?
Heavy slow resistance (HSR) training — such as slow leg press or Spanish squat — is the gold standard. Isometric quadriceps exercises (wall sits) are highly effective for pain relief in the short term, especially before sport.
