Abstract
ObjectiveTo study the repair effect of medial patellar ligament under arthroscopy in the treatment of traumatic patellar instability.
MethodsTwenty patients with traumatic patellar instability treated in our hospital from October, 2017 to October, 2018 were selected as the observation objects. Arthroscopy was performed on the patients during the operation, and the relationship between patella trajectory and joint dynamic matching was evaluated. The sites of the patients' injury were determine and repaired. After the operation, the knee joint function was evaluated by Laresn score after regular rehabilitation and two years’ follow up.
ResultsThe patellar suitable angle and lateral patellar angle were (6.75±2.84)° and (12.5±2.11)° after the operation, which were significantly better than those before the operation (both P<0.05). The Larsen score was (86.85±4.52) after the operation, which was higher than that before the operation (P<0.05). No patella dislocation occurred during the follow-up.
ConclusionRepair of medial patellar ligament is effective in the treatment of traumatic patellar instability, and there is no patellar redislocation. Arthroscopy plays an important auxiliary role in the process of operation.
