摘　　要：目的通过测量，观察胫骨内侧高位截骨术对胫骨后倾角等相关角度的影响，探讨其临床意义。方法1997～2002年，对33例（36膝）膝关节内侧间室骨性关节炎患者行胫骨内侧高位截骨术。男6例，女27例；年龄45～72岁，平均58岁。在手术前后X线片上测量胫骨后倾角，Insall—Salvati指数，胫骨结节高度。采用配对t检验进行统计学分析。结果胫骨内侧高位截骨，术后胫骨后倾角、胫骨结节高度无丢失，差别有显著意义（P〈0．05）。结论胫骨内侧高位截骨术后，胫骨后倾角无减小，无低位髌骨等并发症出现，提示该术较胫骨外侧截骨术具有优势。Objective To investigate the effect of the high medial tibial osteotomy on the changes of related angles of proximal tibia. Methods From 1997 to 2002, 33 patients including 6 men and 27 women with medial unicompartmental osteoarthritis in 36 knees underwent high medial tibial osteotomy. The age of the patients ranged from 45 to 72 years with 58 years old on average. The posterior slope angles of tibia and Insall - Salvati index were measured both preoperatively and postoperatively on lateral radiographs. The alteration of the above features was calculated and analyzed statistically with the paired test. Results The mean tibial posterior slope angle was 5.53°± 1.0°preoperatively and 6.73° ± 1.8°postoperatively. The tibial posterior slope angle was averagely increased by about 1.20° ± 2.2°. The height of tibial tuberosity was averagely increased by 0.34 ±0.19 cm. Statistical analysis indicated that there was significant difference in the posterior slope angle （P 〈 0.05） and the height of tibial tuberosity （P 〈 0. 001 ） between preoperatively and postoperatively. There was no significant difference in Insall- Salvati index in time （P 〉0.05）. Conclusion There are no complications such as the decrease of tibial posterior slope angle and patellar Baia after high medial tibial osteotomy, which indicates that this operation is better than high lateral tibial osteotomy.
