Knee Squeaking Secondary to Intra-articular Nonabsorbable Suture: A Report of 2 Cases

Joint squeaking has classically been described after total hip arthroplasty using a ceramic-on-ceramic bearing surface. This phenomenon has also been found to occur after total knee arthroplasty and can be associated with patient concern and dissatisfaction. However, it has not been described in the postsurgical native knee. We present 2 cases of knee squeaking after medial patellofemoral ligament (MPFL) reconstruction. In both cases, the squeaking sound was a result of nonabsorbable intra-articular suture. In this report, we present the cases as well as the surgical treatments, which ultimately resulted in the successful elimination of joint squeaking.
