The authors describe an original procedure, the patella thinning osteotomy, as an alternative to advancement of the tibial tuberosity or patellectomy in cases of severe anterior knee pain. They present an experimental study on cadaveric knees prior to a clinical trial. This study on 13 knee specimens, using Fujifilm Prescale barosensitive film, shows that thinning of the patella by 7 mm diminishes to a significant degree the patellofemoral contact areas from 16.07% at 60 degrees of flexion to 27.90% at 30 degrees of flexion. Patellofemoral joint reacting forces, measured in 12 knees, also diminish in both medial and lateral surfaces at 30 degrees, 60 degrees and 90 degrees of flexion, the level of statistical significance being over 0.05, except for the lateral surface at 60 degrees of flexion. This technique decompresses the patellofemoral joint, and produces the biological effects found after other osteotomies.
作者描述了一种原创手术方法——髌骨变薄截骨术，作为严重膝前疼痛病例中胫骨结节前移或髌骨切除术的替代方法。他们在临床试验前进行了一项尸体膝关节实验研究。这项对13个膝关节标本的研究使用富士胶片Prescale压敏胶片，结果显示髌骨变薄7毫米可使髌股接触面积在屈膝60度时从16.07%显著减小至屈膝30度时的27.90%。在12个膝关节中测量的髌股关节反作用力在屈膝30度、60度和90度时，内外侧表面均减小，除屈膝60度时外侧表面外，统计学意义水平均超过0.05。该技术可减轻髌股关节压力，并产生与其他截骨术后相同的生物学效应。
