Extensor mechanism disruption after total knee arthroplasty is a significant complication. Patients experiencing this issue demonstrate worse functional outcomes, necessitating intensive management and rehabilitation strategies.

Area of Science:

  • Orthopaedic Surgery
  • Biomedical Engineering

Background:

  • Extensor mechanism disruption is a challenging complication following total knee arthroplasty.
  • Treatment options range from observation to complex reconstructive procedures.

Purpose of the Study:

  • To review current literature on extensor mechanism disruptions after total knee arthroplasty.
  • To analyze functional outcomes in patients with this complication.

Main Methods:

  • Computerized systematic review and literature search.
  • Analysis of a multi-center prospective study of failed total knee arthroplasty patients.
  • Utilized validated health-related quality of life measures.

Main Results:

  • Six of 290 patients (2.07%) in the study cohort experienced extensor mechanism disruption.
