Abstract

|
|
An absence or compromise of the medial collateral ligament that occurs after primary total knee arthroplasty is achallenging reconstructive problem. Treatment usually requires unlinked-constrained total knee arthroplasty. Revision with unlinked-constrained prostheses often causes more bone loss and transmits increased stress to the bone-cement and prosthesis-cement interfaces which can increase the risk of aseptic loosening. However, there are no treatment options other than constrained prostheses. We present a 47-year-old female who suffered from medial instability that occurred after total knee arthroplasty, which was treated successfully by a medial collateral ligament reconstruction.
