Summary
Bilateral patellar tendon rupture, though uncommon, can cause knee extensor mechanism failure. Prompt surgical repair and rehabilitation can restore function and mobility.
Area of Science:
- Orthopedic Surgery
- Trauma Care
- Musculoskeletal Research
Background:
- Bilateral patellar tendon rupture is a rare cause of knee extensor mechanism dysfunction.
- Predisposing factors include systemic diseases and certain medications, but spontaneous cases occur.
- Clinical presentation involves inability to extend the knee, pain, swelling, and a high-riding patella.
Observation:
- A case of a 44-year-old male with no prior risk factors is presented.
- The patient experienced bilateral patellar tendon rupture after minor trauma.
- Treatment involved bilateral primary transosseous end-to-end tendon repair.
Findings:
- Post-operative immobilization was brief, followed by intensive rehabilitation.
- Six months after surgery, the patient achieved unaided walking without pain.
- Full range of motion and unimpeded daily activities were regained in both knees.
Implications:
- Early diagnosis and surgical intervention are critical for extensor mechanism failure.
- Effective management leads to favorable functional recovery.
- This case highlights successful outcomes even without predisposing risk factors.
