Sixty-six knees (sixty patients) that had had a proximal tibial osteotomy were evaluated to determine if any alteration of the patellar height had occurred as a result of the operation. Eighty-nine per cent of the patellae, as measured by the Insall-Salvati index, and 76.3 per cent, as measured by the Blackburne-Peel index, were observed to be lowered as they appeared on the postoperative lateral radiograph. This was probably due to shortening of the patellar ligament after prolonged immobilization in a cast, interstitial scarring of the patellar ligament, and new-bone formation in the area of insertion of the patellar ligament. There was no correlation between the postoperative height of the patella and the need for subsequent revision to a total knee replacement.
对66个接受胫骨近端截骨术的膝关节（60名患者）进行评估，以确定手术是否导致髌骨高度发生任何改变。通过Insall-Salvati指数测量，89%的髌骨在术后侧位X线片上显示降低；通过Blackburne-Peel指数测量，76.3%的髌骨显示降低。这可能是由于长时间石膏固定后髌韧带缩短、髌韧带间质瘢痕形成以及髌韧带附着区域新骨形成所致。髌骨术后高度与后续进行全膝关节置换翻修的必要性之间没有相关性。
