Correction of a Squeaky Knee After ACL Reconstruction Surgery

Case: We report a squeaking knee complication on weight-bearing and active flexion-extension because of a migrating nonabsorbable FiberWire suture in a 16-year-old boy who underwent anterior cruciate ligament (ACL) reconstruction surgery. Although not physically limiting, the noise caused psychological distress in our patient as a young adult. As the noise did not resolve with nonsurgical treatment, we performed arthroscopic surgical correction and removed loose FiberWire strands protruding from the femoral tunnel which completely eliminated the sound. Conclusions: Squeaking knee complications because of migrating nonabsorbable sutures post-ACL reconstruction surgery do not heal with time and can be corrected surgically.
