Correction of a Squeaky Knee After ACL Reconstruction Surgery: A Case Report

A Squeaking Knee Is a Rare Complication of ACL Surgery: A Case Report

CASE

We report a rare case of a 36-year-old woman who underwent anterior cruciate ligament surgery (ACL), which was complicated by a squeaking knee postoperatively. The squeaking noise was likely due to migrating nonabsorbable suture engaging with the articular surface and created significant psychological stress but had no impact on the functional outcome of the patient. We eliminated the noise with an arthroscopic debridement of the suture that had migrated from the tibial tunnel.

CONCLUSION

A squeaking knee after ACL surgery due to migrating suture is a rare complication that, in this case, improved with surgical debridement and diagnostic imaging seems to have a limited role.

All-inside arthroscopic anterior cruciate ligament reconstruction with internal brace Ligament Augmentation using semitendinosus tendon autograft: A case series

Introduction and importance

Anterior Cruciate Ligament (ACL) reconstruction surgery has been proven to be closely related to the graft healing process, which can last up to 12 months after surgery. In recent years, through various biomechanical and clinical studies, Internal Brace Ligament Augmentation (IBLA) has been shown to protect the graft during these early postoperative stages and improve the outcome of ACL reconstruction. We present this case series of all-inside arthroscopic anterior cruciate ligament reconstruction with IBLA using semitendinosus tendon autografts, with the goal of evaluating postoperative clinical and patient-reported outcomes.

Case presentation

A total of 37 patients who underwent all-inside arthroscopic anterior cruciate ligament reconstruction with IBLA using only semitendinosus tendon autografts, were evaluated, in terms of patient reported outcome and clinical assessment, during the 3, 6 and 12 months post-operative follow-up. Results: The mean Lysholm Knee score at the final follow-up was 94,03 +- 3,65 with a difference of 34,59 +- 5,52 to the baseline level. International Knee Documentation Committee (IKDC) classification rated 30 cases of grade A and 7 cases of grade B. In terms of clinical tests and knee's range of motion, all patients have returned to normal, and no cases of re-rupture or other severe complications were found.

Clinical discussion

Early follow-up patient reported outcomes have provided good to great results for the 37 patients who underwent all-inside arthroscopic anterior cruciate ligament reconstruction with IBLA using semitendinosus tendon autografts and no cases of graft failure or other notable complication has been discovered. Clinical findings suggest improved knee's integrity and range of movement during the early stages, which may promote early rehabilitation, however future long-term comparative studies are needed.

Conclusion

IBLA with all-inside ACL reconstructions using only semitendinosus autograft has provided good to great results however, future long-term comparative studies are needed.

Nonabsorbable Suture of a PCL Allograft Resulting in a Squeaking Knee After PCL Reconstruction: A Case Report

CASE

This case report describes the occurrence of a squeaking knee joint on active flexion-extension in a 35-year-old man who had previously undergone posterior cruciate ligament (PCL) reconstruction surgery. The patient suffered from psychosocial distress because of the noise and complained of persistent left knee pain. After nonsurgical treatment failed to resolve the noise, arthroscopic surgery was performed to debride the interposed nonabsorbable suture located on the intra-articular surface, resulting in squeaking sound elimination.

CONCLUSION

Surgery was necessary to alleviate a squeaking knee joint caused by interposed nonabsorbable sutures after PCL reconstruction in this patient.
