Abstract

Objective

The posterior cruciate ligament (PCL) avulsion fracture from its tibial insertion is not a rare condition in west China. Despite the further technical advent in refixation of avulsion fractures, the reported failure rate of current approaches remains high and the optimal surgical technique has not been elucidated yet. The purpose of this study is to introduce an all-inside arthroscopic operation technique for bony tibial avulsion fractures of the PCL and its initial clinical outcomes.
Method(s):
A retrospective analysis of 12 cases (12 knees) of acute PCL avulsion fracture on the clinical date between February 2014 and January 2016. 9 males and 3 females, aged(37.96±5.47)years on average(range, 29-52 years). Two conventional arthroscopic approaches were used to observe the avulsion fracture and place the PCL tibial locator. A proximal medial tibial mini incision was used to drill bone tunnel (Arthrex, USA) through the fracture segment. A pair of TightRope device (Arthrex, USA) were pulled through the bone tunnel from the medial conventional arthroscopic approach and fixed the fracture. The Clinical effectiveness was evaluated by using Lysholm knee functional score. Radiographic imaging studies included DR and CT scans for assessment of fracture healing and anatomic reduction of the bony avulsion.
Result(s):
All patients underwent the operation successfully, type of surgical incision I. All were followed-up 6 to 12 months, average (8.12±1.65). All patients showed complete fracture healing and anatomic reduction of the bony avulsion, and a negative posterior drawer test. The fracture healing time was 4~8 weeks,average(4±2.01). Lysholm knee functional score is 89 ~ 100,average (93.2± 4.35) at the latest follow-up. Total surgical time was(36.15±5.68)min.
Conclusion(s):
All-inside arthroscopic operation technique of tibial avulsion fractures of the posterior cruciate ligament provides satisfactory clinical results. It is a relatively easy technique, which minimizes soft tissue damage and avoids a second operation for hardware removal.
