ABSTRACT
Objective To observe the clinical features of posterior cruciate ligament rupture and compare the efficacy of arthroscopic surgery and conservative treatment. Methods 128 patients, including 63 patients treated by arthroscopic surgery and 65 patients treated by conservative operation were included in the study. Statistical analysis was performed using SPSS 17.0 statistical software package. Results In the present study, after 24 month follow up, the PDT grade in the arthroscopic surgery group was better than that in conservative treatment group. The Lysol score in the arthroscopic surgery group was significantly higher that observed in the conservative treatment group (P < 0.05). There was no significantly difference for the Tiger score between the arthroscopic surgery group and conservative treatment group. Conclusion Arthroscopic treatment of posterior curiae ligament rupture is more effective than conservative treatment, especially in the treatment of joint stability and so on.
