Treatment of avulsion fracture of posterior cruciate ligament at tibial plateau with small transverse popliteal fossa incision:a report of 23 cases
Objective To observe the short-term clinical effect in the treatment of avulsion fracture of posterior cruciate ligament(PCL)at tibial plateau through a small transverse popliteal incision.Methods The clinical and follow-up data of 23 patients with avulsion fracture of PCL at tibial plateau,treated by popliteal transverse small incision in our hospital from March 2018 to June 2021,were retrospectively analyzed.The operation time,bleeding volume,incision condition after operation,fracture reduction and healing were observed.The knee joint flexion and extension before and after operation were compared,and the knee joint function was evaluated by Lysholm score.Results All 23 patients were followed up for an average of 13.2 months.The operation time of this group was 25-50 minutes,with an average of 32 minutes.The average intraoperative bleeding volume was 7.8 ml.All incisions healed normally without complications.In this group,X-ray examinations 1-3 days after operation,3 and 6 months after operation showed that the fractures were well restored without loss of reduction.The fracture line was blurred at 3 months,and basically disappeared at 6 months.The flexion and extension of the knee joint after operation was significantly improved compared with that before operation.Lysholm score was significantly improved 6 months after operation.Conclusions The treatment of avulsion fracture of PCL at tibial plateau with small transverse popliteal fossa incision and direct vision channel has the advantages of rapid exposure,short operation time,less bleeding,less disturbance to popliteal fossa tissue,blood vessels and nerves,fewer complications,rapid recovery,good function,and satisfactory short-term clinical effect.
