To assess functional outcome of posterior cruciate ligament tibial avulsion fracture treated with open reduction internal fixation by cancellous screws with washer through Burk’s and Schaffer’s posteromedial approach

Abstract

Posterior Cruciate Ligament (PCL) tibial avulsion fracture is relatively rare injury. PCL is main posterior stabilizer of the knee. There is controversies in literature about surgical indication for PCL Injuries treatment. But if PCL tibial avulsion fracture left untreated if may leads to chronic instability and early degenerative changes. Numerous technique for treatment of PCL tibial avulsion Fracture have been Described in literature from closed reduction to definite fixation, both open and arthroscopically assisted fixation. Objective of study, to access functional Outcome of Posterior cruciate ligament tibial avulsion fracture treated with open reduction internal fixation by cancellous screws with washer through Burk’s and Schaffer’s Posteromedial approach. Functional outcome measure with Lysholm score. Total thirty patient cases of PCL tibial avulsion fracture were included for study from January 2015 to November 2018, which were operated in our Institute Smt. Kashibai navale medical college and General hospital, Narhe, Pune. Assessment with help of clinically, Radiologically and functional outcome by Lysholm score. We got result like, age of the patients was between 20-50years (Avg. 35.6years).Total follow up months between 6-12 months (Avg. 8.3 Months). Preoperative Lysholm score between 25-35 (Avg. 29.8). Postoperative Lysholm score between 84-100 (Avg. 96 which is excellent). Male to Female incidence ratio was 2.7:1. There were 3 patients with Postoperative Laxity with Mild grade (< 5 mm). There three patients with Residual pain after last follow up but on radiographic study found union. There Four patients with Superficial infection which were treated with oral antibiotics and cure that only no need operative procedure for same. We concluded as, PCL tibial avulsion treated with open reduction and internal fixation by one cancellous screws with washer through Burk’s and Schaffer’s posteromedial approach leads to excellent clinical results, radiological findings and functional outcome.
