Patellar tendinopathy treatment
Patellar tendinopathy develops when the tendon connecting the kneecap to the shin bone is loaded beyond its capacity. It is common in jumping sports, and its treatment is based not on rest but on graded loading.
Also known as: Jumper's knee, patellar tendinitis
What is it?
A tendon is dense connective tissue transferring the force a muscle produces to bone. During jumping and landing the patellar tendon carries loads well above body weight. When that load exceeds the tendon's capacity to adapt, its structure changes and pain appears.
For years this was called 'tendinitis' and assumed to be inflammatory. It is now known that the real problem is not classic inflammation but disruption of collagen structure and failure of the tissue to adapt to load. That understanding changed treatment: controlled loading replaced ice and rest.
The pain has a characteristic behaviour: it is marked at the start of activity, eases with warming up, then increases again afterwards, with stiffness the next morning. This 'warms up with activity' pattern is the most typical feature of tendinopathy and strongly supports the diagnosis.
Symptoms
- Point pain just below the kneecap
- Pain marked at the start of activity that eases with warming up
- Symptoms worse after activity and the following morning
- Pain accentuated by jumping, landing and squatting
- Tenderness on pressing the tendon
- Stiffness after prolonged sitting
- Pain increased descending stairs
Causes and risk factors
- A sudden increase in jumping and landing volume
- Training on hard surfaces with insufficient recovery
- Weakness in the quadriceps and hip muscles
- Poor landing technique
- Restricted ankle range, shifting load onto the knee
- Rapid increases in load at the start of a season
The assessment
The behaviour of the pain is explored in detail; a pattern that eases with warm-up then worsens afterwards strongly suggests tendinopathy. Point tenderness over the tendon is sought and pain reproduced with a single-leg squat.
Quadriceps and hip strength, ankle range and landing technique are assessed. Changes in training volume are recorded in detail — loading history is an inseparable part of the diagnosis here. Patellofemoral pain and fat pad irritation are ruled out.
Course of treatment
Weeks 0–2
Regulating load
Jumping volume is temporarily reduced, but the tendon is not fully rested — inactivity weakens it further. Isometric loading is started, as this type of contraction markedly reduces pain.
Weeks 2–8
Heavy slow loading
Slow-tempo, heavy resistance training is applied. This is the approach with the strongest evidence for reorganising tendon structure. Hip strength is developed in parallel.
Weeks 8–16
Energy storage loading
Jumping and landing are progressively reintroduced. The tendon's adaptation to rapid loading happens in this phase and is required for return to sport.
Maintenance
Load management
Training volume is managed with gradual weekly increases. Strength work continues through the season; if stopped, tendon capacity falls and symptoms return.
How long does it take?
Tendinopathy requires patience. Clear improvement is not expected before twelve weeks and full return to sport can take three to six months, with a programme of 12–20 sessions. Early return is the most common cause of recurrence, while outcomes are good with a correct loading programme.
When to see a doctor
The findings below fall outside the scope of physiotherapy and require medical assessment.
- Sudden severe pain with inability to straighten the knee — possible tendon rupture
- The kneecap appearing to sit higher than normal
- Fever, redness and warmth
- Large swelling developing rapidly after injury
- Pain not relieved by rest at night and steadily increasing
Frequently asked questions
Is rest alone not sufficient?
Complete rest weakens the tendon and pain recurs more easily on return. The right approach is not removing load but setting it at a level the tendon tolerates and building up from there.
Is it possible to exercise with pain?
Yes, within acceptable limits. Mild pain during exercise is not a problem; the criterion is that pain returns to baseline by the next morning. If it does not, the load was too high and that step is scaled back.
Is it advisable to ice it?
Ice can reduce pain temporarily but does not improve tendon structure. In tendinopathy the actual treatment is loading; ice is only used as support during very painful periods.
Why does it take so long?
Tendon tissue adapts far more slowly than muscle and has a poorer blood supply. Structural change takes weeks to months. There is no shortcut, and returning early only lengthens the process.
