Quadriceps tendon rupture
Rupture of the quadriceps tendon is usually associated with forced flexion of the knee or a direct blow, although spontaneous ruptures are reported.
Predisposing illnesses include:
- connective tissue disorders
- renal impairment
- corticosteroid use
Most ruptures are thought to occur at around the osseotendinous junction at the superior pole of the patella 4.
