Quadriceps tendon rupture
Citation, DOI & article data
Quadriceps tendon rupture 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
- complication of total knee arthroplasty (very rare) 6
Most ruptures are thought to occur at or around the osseotendinous junction at the superior pole of the patella 4.
