- Irritation occurs at the proximal attachment of the patellar tendon with pain and tenderness just distal to the distal pole of the patella.
- Can affect growing children involved in sports: as their body mass increases, more stress is placed on the tendon.
- Risk factors include corticosteroid use / abuse, rheumatoid arthritis and chronic renal failure.
Quadriceps tendinopathy may be due to overuse or may be secondary to age-related tendon degeneration
