Permanent resection or excision arthroplasty of the knee involves the removal of any infected prosthetic material and thorough debridement, with no further reimplantation. The more common alternatives to permanent resection arthroplasty include knee arthrodesis or above-knee amputation (AKA).
We describe two cases of complex periprosthetic infections of the knee associated with subsequent osteomyelitis, which were unsuitable for re-revision arthroplasty. Both patients chose to remain with an excision arthroplasty, rather than undergo arthrodesis or AKA, respectively, and were satisfied with their quality of life at long-term follow-up.
Although permanent resection arthroplasty of the knee is rarely performed, it remains a limb salvage option in certain cases where bone loss is limited, functional demands are low, and further surgery may present a significant risk.
膝关节永久性切除或切除成形术包括去除任何感染的假体材料并进行彻底清创,不再进行重新植入。永久性切除成形术更常见的替代方法包括膝关节融合术或膝上截肢(AKA)。
我们描述了两例膝关节复杂的假体周围感染并随后发生骨髓炎的病例,这两例均不适合再次翻修关节成形术。两名患者分别选择保留切除成形术,而不是接受融合术或膝上截肢,并且在长期随访中对其生活质量感到满意。
尽管膝关节永久性切除成形术很少进行,但在某些骨丢失有限、功能需求低且进一步手术可能存在重大风险的情况下,它仍然是一种肢体挽救选择。
