Arthroscopy-assisted reduction of posteromedial tibial plateau fractures with buttress plate and cannulated screw construct.

Purpose: To present the radiologic and clinical results of posteromedial fractures treated with arthroscopy-assisted reduction and buttress plate and cannulated screw fixation.

Methods: Twenty-five patients with posteromedial tibial plateau fractures treated by the described technique were included in this study. According to the Schatzker classification, there were 5 type IV fractures (20%), 2 type V fractures (8%), and 18 type VI fractures (72%).

Arthroscopic suture fixation for avulsion fractures in the tibial attachment of the posterior cruciate ligament.

Purpose: The purpose of the study was to highlight our surgical technique of arthroscopic suture fixation for acute tibial eminence posterior cruciate ligament (PCL) avulsion fractures, clinical and radiographic outcomes, and complication rates.

Methods: This prospective study enrolled patients who had undergone arthroscopic reduction and suture fixation by use of 4 No. 5 Ethibond sutures (Ethicon, Somerville, NJ) for image-proven displaced PCL attachment fractures of the tibial eminence with posterior knee instability of grade II or higher.
