The results of 52 Groupe d'utilisation et d'expérimentation des prosthèses articulaires (GUEPAR) unicompartmental Lotus knee prostheses implanted for osteoarthritis of the knee are analyzed with a follow-up time exceeding five years (five to nine years). Thirty-five knees had no weight-bearing pain, six knees had slight pain, three knees had moderate pain, and eight knees had revisions. Except for one complication from infection, all the poor results (eight revisions and three knees with moderate pain) in terms of pain can be explained by mechanical causes, i.e., femorotibial subluxation, loosening of the tibial component, or narrowing of the nonprosthetic femorotibial space. Because the cause of these poor results appears to be due to malposition of the prosthesis component, or to components that are too thick with an inadequate mechanical axis, the precision of the surgical procedure is important.
对52例因膝关节骨关节炎植入单髁Lotus膝关节假体的Groupe d'utilisation et d'expérimentation des prosthèses articulaires (GUEPAR) 病例进行分析，随访时间超过5年（5至9年）。35例膝关节无负重疼痛，6例膝关节有轻微疼痛，3例膝关节有中度疼痛，8例膝关节进行了翻修。除1例感染并发症外，所有在疼痛方面的不良结果（8例翻修和3例中度疼痛的膝关节）均可用机械原因解释，即股骨胫骨半脱位、胫骨部件松动或非假体股骨胫骨间隙变窄。由于这些不良结果的原因似乎是假体部件位置不当，或部件过厚且机械轴不合适，手术操作的精确性很重要。
