Cementless knee arthroplasty becomes more and more popular worldwide. At the beginning of endoprosthetics era, cementless implants showed unsatisfactory results. However, surgical technologies develop rapidly and nowadays the cementless fixation shows better outcomes.
To analyze the experience of total knee arthroplasty using cementless fixation for the treatment of advanced arthritis of the knee.
We operated on 130 patients. The mean follow-up duration was 36 months. In 70 patients we used cementless fixation and in 60 patients we used implants with cemented fixation. To evaluate the results, we used KOOS scale and WOMAC scale. We also evaluated the mean duration of surgical intervention and blood loss.
In the cementless group WOMAC and KOOS scales scores before the operation were 198,2 (±35.7) and 23,1 (±3.4), respectively, and in the cemented group it was 199.3(±36.8) and 24.9 (±2.1), respectively(p > 0,05). One year after the operation, KOOS and WOMAC scores were 54.5(±12.6) and 83.6(±8,.2) in the cementless group and 78.9(±4.6) and 66.9(±5.7) in the cemented group(p < 0,05)., respectively. Intraoperative blood loss was 255(±89,3) in the cemented group and 315(±52,1) in cementless group(p < 0,05). Postoperative blood loss was 515(±119, 5) and 440(±129,3)) (p < 0,05), respectively. Mean duration of intervention was 78 min (±6,8) in cemented group and 64 min (±8,7) in cementless group(p < 0,05).
1We have better functional results using implants with cementless fixation.2There was a greater intraoperative and postoperative blood loss in cementless group.3Cementless knee arthroplasty associated with shorter duration of intervention than cemented.
非骨水泥型膝关节置换术在全球范围内越来越受欢迎。在假体植入时代初期，非骨水泥型植入物的效果并不理想。然而，手术技术迅速发展，如今非骨水泥固定显示出更好的效果。
分析采用非骨水泥固定进行全膝关节置换术治疗晚期膝关节关节炎的经验。
我们对130例患者进行了手术。平均随访时间为36个月。70例患者采用非骨水泥固定，60例患者采用骨水泥固定植入物。为了评估结果，我们使用了KOOS量表和WOMAC量表。我们还评估了手术干预的平均持续时间和失血量。
非骨水泥组术前WOMAC和KOOS量表评分分别为198.2（±35.7）和23.1（±3.4），骨水泥组分别为199.3（±36.8）和24.9（±2.1）（p>0.05）。术后一年，非骨水泥组KOOS和WOMAC评分分别为54.5（±12.6）和83.6（±8.2），骨水泥组分别为78.9（±4.6）和66.9（±5.7）（p<0.05）。骨水泥组术中失血量为255（±89.3），非骨水泥组为315（±52.1）（p<0.05）。术后失血量分别为515（±119.5）和440（±129.3）（p<0.05）。骨水泥组平均干预持续时间为78分钟（±6.8），非骨水泥组为64分钟（±8.7）（p<0.05）。
