A low patella is frequently a complication of a lesion of the knee but it can also present secondary symptoms of its own. The authors describe an original method for assessment of the vertical level of the patella. They have tried to establish a relationship between the low situation of the patella and pain of a certain type associated with limited flexion of the knee. Physiopathological and biomechanical evidence is taken into account. In most instances, a low patella is secondary either to a mechanical cause, natural or iatrogenic, or to an inflammatory cause such as algodystrophia. 29 patients out of 128 observed cases have been operated on. 17 of these were due to excessive transplantation of the anterior tibial tubercle. In most of the cases the tibial tubercle was transplanted upwards in association with a joint release. In only 3 cases a patellectomy was done. The results were excellent or good in half of the cases and unsatisfactory in the other half.
低位髌骨常常是膝关节损伤的并发症，但它也可能有其自身的继发症状。作者描述了一种评估髌骨垂直位置的原始方法。他们试图建立髌骨低位与某种类型的、与膝关节屈曲受限相关的疼痛之间的关系。同时考虑了生理病理学和生物力学证据。在大多数情况下，低位髌骨继发于机械性原因，包括自然的或医源性的，或者继发于诸如骨萎缩性肌痛等炎症性原因。在128例观察病例中，有29例接受了手术。其中17例是由于胫骨结节过度移位。在大多数病例中，胫骨结节向上移位并同时进行关节松解。仅3例行髌骨切除术。结果一半病例为优或良，另一半病例不理想。
