Arthroscopic Treatment for Acute Avulsion Fracture of Posterior Cruciate Ligament:Two Cases Report / 中国康复理论与实践

ABSTRACT

Objective To explore the efficacy of arthroscopic treatment for acute avulsion fracture of posterior cruciate ligament (PCL) using double titanium plate TightRope. Methods From December 2014 to January 2015, two cases with acute avulsion fracture of PCL were treated with double titanium plate TightRope under arthroscopy, after assessment of three dimensional reconstructive CT and MRI. Rehabili-tation was carried out after operation. Results One case succeeded with double titanium plate TightRope, and rehabilitation could be per-formed early postoperatively. Another case failed in TightRope fixation, and accepted two internal hollow screws fixation instead. Rehabili-tation was delayed until two weeks postoperatively. The function of the knee was satisfactory in the former patient after three months, who could extend the knee in a normal range, without pain or locking. The same effect was gained in the latter patient after four months. Conclu-sion For acute tibial avulsion fracture of PCL with larger and intact fragment without osteoporosis, arthroscopic restoration and fixation with double titanium plate TightRope offers the opportunity to achieve anatomic reconstruction and rigid fixation for early rehabilitation in adult patients.
