A series of 51 patients (55 knees) with implanted GUEPAR totally constrained endoprosthesis was followed up clinically and radiologically for a mean of 5.0 years (range 1.5-11.8 years). Good relief of pain, increased range of knee movement and of walking capability were observed. There was, however, an unacceptable amount of severe complications. Three endoprostheses had to be removed and arthrodesis performed. Revision arthroplasty was carried out in 8 cases due to aseptic loosening of the prosthesis. In 25 cases lateral displacement or total dislocation of the patella was confirmed with tangential patellar X-ray projections. We suggest that the GUEPAR totally constrained total knee endoprosthesis and similar constructions should be chosen in only special cases, when aged patients have extremely damaged and unstable knee joints and non-constrained prostheses are not considered suitable.
对51例（55膝）植入GUEPAR全限制型膝关节假体的患者进行了平均5.0年（范围1.5 - 11.8年）的临床和放射学随访。观察到疼痛得到良好缓解，膝关节活动范围和行走能力增加。然而，出现了数量不可接受的严重并发症。3个假体不得不被取出并进行关节融合术。8例因假体无菌性松动进行了翻修关节成形术。通过髌骨切线位X线片证实25例存在髌骨外侧移位或完全脱位。我们建议，GUEPAR全限制型全膝关节假体及类似结构仅应在特殊情况下选用，即老年患者膝关节严重受损且不稳定，而非限制型假体被认为不合适时。
