In 42 patients with idiopathic chondromalacia patellae, the effect of anterior displacement of the tibial tuberosity was evaluated in a prospective and randomized study. The operation performed was a modified Bandi procedure, and it resulted in significant relief of the patellofemoral pains, compared with the effect of a standard shaving procedure. Shaving alone was done in 22 patients of whom 6 (27 per cent) were classified as good, a result which may have been due to the placebo effect. In another 20 patients shaving was combined with anterior displacement of the tibial tuberosity resulting in pain relief in 18 (9 degrees per cent). The lack of unambiguously good results may be due to the fact that, although an anterior displacement reduces the retropatellar pressure, it cannot by itself compensate for an abnormal, dynamic tracking pattern of the patella.
在一项前瞻性随机研究中，对42例特发性髌骨软骨软化症患者评估了胫骨结节前移的效果。所施行的手术为改良的班迪手术，与标准的髌骨表面切削术相比，该手术能显著缓解髌股关节疼痛。单独接受髌骨表面切削术的22例患者中，有6例（27%）效果良好，这一结果可能归因于安慰剂效应。另外20例患者接受了髌骨表面切削术联合胫骨结节前移手术，其中18例（90%）疼痛得到缓解。明确良好的结果较少，可能是因为尽管胫骨结节前移可降低髌后压力，但它本身无法弥补髌骨异常的动态轨迹模式。
