[Abstract] Objective〖HTSS〗〓To compare the clinical efficacy about the reform triple combined operation and tradition triple combined operation for curing recurrent patellar dislocation by using arthroscopy.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Thirtyseven patients with recurrent patellar dislocation were divided into control group(18 patients with 21 knees) and research group(19 patients with 23 knees), the patients in control group were treated with tradition triple combined operation by using arthroscopy(lateral retinaculum release surgery, medial retinaculum compression surgery, tibial tubercle osteotomy move inside and shift surgery), and the patients in research group were treated with reform triple combined operation by using arthroscopy(lateral retinaculum release surgery, medial patellofemoral ligament reconstruction, tibial tubercle osteotomy move inside and shift surgery). The tilt angle, patellofemoral angle, lateral shift, Kujala scores, Tegner scores, Lyshoim scores were compared in two groups before and after treatment.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Compared with pretreatment treatment, the tilt angle, patellofemoral angle, lateral shift were decreased in two groups after treatment, but the Kujala scores, Tegner scores, Lyshoim scores were increased, the difference was statistically significant(P<005). Compared with after 3 months′ treatment in control group, the tilt angle, patellofemoral angle, lateral shift were decreased in research after 3 months′ treatment, but the Kujala scores, Tegner scores, Lyshoim scores were increased, the difference was statistically significant(P<005). The excellent and good rate of research group was significantly higher than that of the control group, the difference was statistically significant(Z=-2.085, P=0.037).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓There are more effective about restoration of patellofemoral structure, biomechanical structure and improvement of patellofemoral joint function by reform triple combined operation than these of tradition triple combined operation, which reflects the advantage of patellar ligament reconstruction, and it is worthy of clinical application.
