Unicompartmental knee arthroplasty was conceived for the treatment of osteoarthritic knees with deterioration of either the medial or lateral compartment of the knee. The Unicondylar prosthesis was used in 19 medial and 5 lateral compartment arthroplasties. A two to 4 year follow-up evaluation of these patients was somewhat disappointing as only 5 knees could be rated excellent and 6 rated a good result. The best results were seen in the lateral compartment arthroplasties. Such deformities may be the only future indication for the use of this operation as these knees do not do well when treated by tibial osteotomy. However, when only the medial compartment is involved, osteotomy may still remain the treatment of choice.
单髁膝关节置换术旨在治疗膝关节内侧或外侧间室退变的骨关节炎膝关节。在19例内侧间室和5例外侧间室关节置换术中使用了单髁假体。对这些患者进行的2至4年随访评估结果有些令人失望，因为只有5例膝关节被评为优，6例被评为良。外侧间室关节置换术的效果最佳。此类畸形可能是该手术未来唯一的适应证，因为这些膝关节采用胫骨截骨术治疗效果不佳。然而，当仅内侧间室受累时，截骨术可能仍是首选治疗方法。
