Extensor mechanism disruption, either from tendon rupture or patellar fracture, is uncommon — typically occurring in less than 2% of patients after total knee arthroplasty. However, the implications of an extensor mechanism disruption are at the top of the pyramid in terms of the potential ill consequences and resulting functional deficits.

While I am a firm believer that aspirin is effective for the majority of our patients as a form of DVT and thromboembolism prophylaxis after total knee and total hip arthroplasty, I am not militant in my approach.
