Aseptic loosening is a considerable complication that affects the longevity of total knee arthroplasty (TKA) implants. Surgeon technique may help minimize aseptic loosening after TKA. Meticulous cementation of the prosthesis and the bone surface during various stages of cement polymerization will maximize cement adherence to the prosthesis and the bone, respectively. Pressurization of the cement in the canal and at the cut surface to achieve at least 2 mm of cement depth penetration has been reported to increase TKA implant longevity.
无菌性松动是影响全膝关节置换术（TKA）植入物使用寿命的一个重要并发症。外科医生的技术可能有助于减少 TKA 后的无菌性松动。在水泥聚合的各个阶段，仔细地将假体和骨表面固定在一起，将分别使水泥最大限度地附着在假体和骨上。据报道，对水泥管内和切割面进行加压，以达到至少 2 毫米的水泥深度渗透，可增加 TKA 植入物的使用寿命。
