超重患者通常被认为不适合全膝关节置换术。为了评估这一禁令的有效性，我们分析了109例患者的两年随访数据。记录特殊外科医院评分，检查x线片放射率，并进行等速强度测试。手术时间、放射率的存在和严重程度以及关节的等动强度与患者体重有统计学意义的正相关。研究发现，特殊外科医院评分与体重低于80公斤的患者的体重呈负相关，与患者体重超过理想体重的比例呈负相关。然而，多元回归分析表明，这些相关性是由患者性别引起的，而不是由体重引起的任何独立影响。从临床角度来看，本研究的结果表明，骨科医生可以预期，他们的全膝关节超重患者在术后最初两年的时间里，不会因为体重而处于明显的术后功能劣势。
Overweight patients are often considered poor candidates for total knee arthroplasty. For assessment of the validity of this proscription, two-year follow-up data from 109 patients were analyzed. Hospital for Special Surgery Scores were recorded, roentgenograms were inspected for radiolucencies, and isokinetic strength tests were conducted. Surgical time, the presence and severity of radiolucencies, and isokinetic joint strength were found to have statistically significant, positive correlations with patient weight. The Hospital for Special Surgery Score was found to have negative correlations with weight for those patients weighing less than 80 kg, and it was found to have negative correlations with the percentage by which patients were heavier than their ideal weights. However, multiple regression analyses indicated that these correlations were caused by patient gender and not by any independent effect due to weight. From a clinical point of view, the results of this study suggest that orthopedists can expect their overweight total knee patients not to be at a significant postoperative functional disadvantage because of their weight during the initial, two-year postoperative period.
