Abstract:
Objective:To investigate the early clinical efficacy of arthroscopic suture and transoral tunnel Versalok anchor fixation in the treatment of acute posterior cruciate ligament (PCL) femoral avulsion fractures in adults.Methods:A retrospective study was conducted to analyze the clinical data of 4 patients with acute PCL femoral insertion avulsion fracture who had been treated at Sports Medicine Center, Xi'an Honghui Hospital from January 2019 to June 2023. They were 1 male aged 49 years old and 3 females aged 39, 44, and 59 years old. Their time from injury to surgery was 3, 4, 9, and 12 days, respectively. All patients underwent arthroscopic suturing of the PCL femoral avulsion ligament junction. The sutures were pulled towards the medial femoral condyle through a bone tunnel created in the area of the medial femoral condyle ligament footprint and fixated with the Versalok anchor. Magnetic resonance imaging (MRI) was performed at 6 months postoperatively to assess union of the avulsion fracture and PCL continuity. The postoperative active knee flexion and extension, ligament tension, knee stability and knee functional recovery were recorded at the final follow-up.Results:One female patient sprained her knee while walking 6 months after surgery and then gradually developed knee pain and instability symptoms with a positive posterior drawer test (grade Ⅲ). She underwent PCL ligament reconstruction 7 months after surgery so that her follow-up was terminated. The remaining 3 patients were followed for 6, 12 and 13 months, respectively. Their active knee extension and flexion activities were comparable to those on the unaffected side and within the normal range at the last follow-up. Two patients had a negative posterior drawer test and 1 patient a positive posterior drawer test (grade I) but no symptoms of knee instability.Conclusion:Arthroscopic suture and bone tunnel Versalok anchor fixation technique in the treatment of acute femoral PCL avulsion fractures in adults is feasible and effective.
