Abstract
This report describes the use of arthroscopic fixation for five cases of tibial eminence fracture.
All the patients were male (average age 20.0 yr), and classified as Meyers-McKeever type 2 by X-ray imaging and computed tomography (CT). Displaced fragments were reduced arthroscopically, fixed with Ethibond sutures by the pull-out method in two cases, and fixed with cannulated cancellous screws in three cases. At ten days after surgery, range of motion (ROM) exercise and weight-bearing were started with an anterior cruciate ligament brace. Postoperative results were evaluated by X-ray, CT, MRI imaging, Lysholm score, and Kneelax arthrometer. At one year after surgery, bone union had been achieved all cases; the average Lysholm score was 98.6, and the knee-lax translation was 0.71 mm. None of the patients showed ROM limitation, anterior instability, or rotational instability. We have used pull-out fixation with Ethibond suture for small fragments, and screw fixation for large fragments. Both methods can be performed arthroscopically. In this series, all the cases were fixed with these two methods, and showed good postoperative outcomes.
