45 Walldius knee joints have been reevaluated an average of 3 years after implantation. 75% were considered good to excellent when compared with the preoperative situation. Most failures were due to infection (11%). The end result depends largely on the condition of adjacent joints which frequently prevent a major improvement in walking ability inspite of a successful implantation of a Walldius prosthesis. The Walldius hinge joint was prefered over other designs because of its large weight-bearing flanges. It can absorb static forces better without sinking into the tibial or femoral shafts. Inspite of a resection of 3 cm, a fusion is still possible if necessary. The use of cement is emphasised to prevent migration of the prosthesis and fracture of the shafts. Inspite of a high complication rate the prosthestic replacement of a severely destroyed knee joint by a Walldius hinge is a promising procedure.
45个瓦尔迪厄斯膝关节在植入后平均3年进行了重新评估。与术前情况相比，75%被认为良好至优秀。大多数失败是由于感染（11%）。最终结果在很大程度上取决于相邻关节的状况，尽管瓦尔迪厄斯假体植入成功，但相邻关节状况常常妨碍步行能力的显著改善。由于其较大的承重凸缘，瓦尔迪厄斯铰链关节比其他设计更受青睐。它能更好地吸收静力而不会陷入胫骨干或股骨干。尽管切除了3厘米，但如有必要仍可进行融合。强调使用骨水泥以防止假体移位和骨干骨折。尽管并发症发生率很高，但用瓦尔迪厄斯铰链对严重受损的膝关节进行假体置换仍是一种有前景的手术。
