What are the symptoms of patellar tendonitis?
The main symptom is pain at the front of the knee, in the tendon just below the kneecap. The NHS describes it as pain between your kneecap and shin, often caused by repetitive running or jumping. It is usually felt when the tendon takes load: jumping, landing, running, squatting, kneeling or walking down stairs.
Many people find the pain eases once they are warmed up and comes back after the session, and over time it can start earlier and linger longer. Tendonitis and tendinopathy are both used for this problem. Tendinopathy is the more accurate word, because long-running tendon pain of this kind is mainly a loss of capacity in the tendon, which is why extracorporeal shockwave therapy is only ever an addition to rebuilding that capacity.
