Some modifications to the treatment of valgus and varus deformities caused by gonarthrosis, and a new radiological technique, for normal and pathological patterns of valgus and varus, which give more security and simplify the procedure, are presented. With this technique it has been established that the normal knee should have a valgus-angle of between +3 degrees and -7 degrees. Outside these values, the knee condition is pathological. Valgus is considered positive (+) and varus negative (-). A new, simple double-angle retractor for the knee and very thin osteotomes are presented in order to facilitate the operation. There are also some variations to the surgical technique, two incisions being made. The fibular osteotomy is made in the head rather than the diaphysis, with elimination of the superior tibiofibular joint to give space for retractor placement. A resistant and simple metal appliance is presented; it allows early mobilization of the knee, thus reducing the cast period from six to two and a half weeks.
本文介绍了对膝关节炎引起的膝外翻和膝内翻畸形治疗方法的一些改进，以及一种新的放射学技术，用于观察膝外翻和膝内翻的正常及病理模式，该技术能提供更高的安全性并简化手术过程。通过这项技术已确定，正常膝关节的外翻角应在 +3度至 -7度之间。超出这些值，膝关节状况即为病理状态。外翻被视为正值（+），内翻为负值（-）。本文还介绍了一种新型、简单的膝关节双角度牵开器以及非常薄的骨凿，以方便手术操作。手术技术也有一些变化，采用两个切口。腓骨截骨在腓骨头而非骨干进行，并切除上胫腓关节，以便为牵开器放置留出空间。还展示了一种坚固且简单的金属器具；它能使膝关节早期活动，从而将石膏固定期从六周缩短至两周半。
