Abstract:

BACKGROUND: Patellar tendon plays a very important role in the movement of knee joint. Patellar tendon rupture is relatively rare in clinic, so the misdiagnosis rate is high. There are many ways for patellar ligament reconstruction and the therapeutic effect is very different. Improper treatment can lead to patella malposition that would seriously affect the function of the knee joint.
OBJECCTIVE: To explore the clinical efficacy of autologous tendon graft with preserved distal insertions on the treatment of old patellar tendon rupture.
METHODS: Eight patients with unilateral old patellar tendon rupture underwent reconstruction using semitendinosus-gracilis tendons with preserved distal insertions. After patellar ligament reconstruction, semi-circular gypsum was used for fixation and the knee joint was kept in flexion of 15° for 1 week. At 2 weeks after patellar ligament reconstruction, surgical incision suture was removed, and 2 weeks later, gypsum was removed for quadriceps isometric and isotonic exercises. At 6 weeks after reconstruction, adjustable knee brace was used for the range of motion exercise, three times per day, and the flexion angle was increased for 10° every week. The patients had fully weight-bearing walking at 3 months after patellar ligament reconstruction.
RESULTS AND CONCLUSION: All patients had no complications after patellar ligament reconstruction, and X-ray film showed that the patella returned to normal height. Function of knee joint had generally returned to normal. No patient had knee discomfort after walking for two kilometers in 24 months. Compared with that before patellar ligament reconstruction, Lysholm score of the patients at 24 months after reconstruction was increased significantly (P < 0.05). The results indicate that semitendinosus-gracilis tendons with preserved distal insertions used for patellar ligament reconstruction can reconstruct and treat old patellar tendon rupture.
