Abstract:
[Objective]To discuss the efficacy of medial wedged proximal tibial osteotomy for treating genu varus deformity.[Methods]From July 1998 to October 2007,49 patients with genu varus deformity were treated by medial wedged proximal tibial osteotomy combined with internal fixation.Full-length anterior-posterior radiographs were taken preoperatively at 8 weeks and 1.5 years postoperatively.The parameters including the femorotibial angle and the medial joint space were measured on the radiographs.The pre-and postoperative function of knee were evaluated according to the HSS score system of the knee.[Results]All the 49 patients were followed up from 18 to 128 months.The mean postoperative femorotibial angle decreaced from 187.5??5.3? to 172.6??3.6?.The mean postoperative HSS score significantly improved from 83.2?15.3 to 47.2?17.6 points after 1.5 years of operation.The medial joint space increased from(2.4?1.2) mm to(4.3?1.2) mm.There were complications in 5 cases: 3 cases of intra-articular fracture during operation and 2 of postoperative superficial wound infections.There were no delayed union,no recurrence of varus deformity,and no blood vessels or nerves injury in all cases.The pain relieved and walking function improved significantly postoperativly.[Conclusion]Medial wedged proximal tibial osteotomy combined with internal fixation is an effect approach to treat genu varus deformity.
