Abstract:
BACKGROUND:From the biological structure, the posterior cruciate ligament is surrounded by the synovial folds of posterior capsule, arising from the inner side of the medial femoral condyle to the posterior part of tibial intercondyloid spine. The main traditional treatment method for posterior cruciate ligament tibial avulsion fracture is open operation, but it is difficult in anatomic reduction, cannot ful y restore knee joint stability and has a great negative impact on the normal function of posterior cruciate ligament. OBJECTIVE:To investigate the effects of arthroscopic implant internal fixation in the treatment of tibial avulsion fracture of the posterior cruciate ligament. METHODS:120 patients with tibial avulsion fracture of the posterior cruciate ligament were randomly assigned into treatment group and control group, with 60 cases in each group. The control group was given the traditional open surgery, and the treatment group was given the arthroscopic surgery. After 3 months, International Knee Documentation Committee (IKDC) scores and Lysholm scores were detected in the two groups;the knee joint range of motion was determined before and 3 months after treatment. RESULTS AND CONCLUSION:Wounds were healed at stage I in al patients with no serious complications. There was no difference in the knee joint range of motion between the two groups before treatment, but the range of motion was increased significantly in both two groups at 3 months after treatment (P<0.05), meanwhile which was higher in the treatment group than the control group (P<0.05). At 3 months after treatment, the excel ent knee function rate was significantly higher in the treatment group (97%) than the control group (88%) according to the Lysholm scores;the IKDC scores were significantly higher in the treatment than the control group in terms of claudication, support, pain, swel ing, and squat (P<0.05). These results indicate that the arthroscopic implant fixation of tibial avulsion fracture of the posterior cruciate ligament has better short-term effects to promote recovery of knee joint function, but no serious complications.
