Medial patellofemoral ligament reconstruction with semitendinosus tendon autograft for the treatment of patellar dislocation with arthroscopic-assisted / 中国医师进修杂志

ABSTRACT

Objective To evaluate the clinical effects of medial patellofemoral ligament reconstruction using the semitendinosus tendon autograft for the treatment of the patellar dislocation.Methods From January 2007 to January 2010,16 cases of patellar dislocation were included in this group.Lysholm score was averaged preoperatively.Arthroscopic-assisted in the semitendinosus tendon autograft reconstruction of the medial patellofemoral ligament,the central graft were fixed on the inner edge of the patellar in the upper 1/3 and the mid-point location,the end were fixed on the channel of femoral epicondyle and adductor tubercle.Results All the patients that lined progressive knee rehabilitation after operation,returned to normal walking for 3 months,6 months could be sports.Followed up for 7-54( 26.36 ± 20.48 ) months,all of patients incision were healed as grade Ⅰ,knee function were normal.Postoperative Lysholm score (93.21 ± 4.68) scores compared with preoperative ( 76.53 ± 8.35 ) scores was significant difference (P ＜ 0.05 ).Conclusions Using the semitendinosus tendon autograft for the treatment of the patellar dislocation method is simple and can effectively restore normal patellar trajectory.At the same time,which is an effective surgical method to treat recurrentdislocation of the patellar.
