摘      要：BACKGROUND The posterior cruciate ligament(PCL) is important for cruciate-retaining(CR)total knee arthroplasty(TKA). Whether the entire PCL should be retained during CR-TKA is *** To evaluate the clinical outcomes of PCL preservation in CR-TKA and the methods used to deal with the PCL during *** A retrospective review of patients with osteoarthritis undergoing primary CRTKA(176 patients, 205 knees) in our institution between March 2012 and March 2014 was performed. A PCL protector was used to preserve the intact PCL bone block. The status of the PCL was recorded during surgery. Intact PCL preserved,pie-crusting and repairing were used to balance the tension of the PCL. Range of motion(ROM) and the Knee Society Clinical Rating system(KSS) were evaluated preoperatively and at the endpoint of *** The mean ROM of the knee was 103.2 ± 17.2°, KSS clinical score was 47.6 ± 9.5 and KSS functional score was 46.3 ± 11.9 before surgery. The mean ROM of the knee was 117.5 ± 9.7°, KSS clinical score was 89.2 ± 3.6 and KSS functional score was 84.6 ± 9.8 at 5 years follow-up. ROM, KSS clinical scores and KSS functional scores were significantly improved after surgery(P 0.05).CONCLUSION The clinical outcomes
