Total knee arthroplasty is a common treatment of osteoarthritis, although unicompartmental knee arthroplasties are frequently used to retain unaffected compartments. Joint space width (JSW) is a major factor in determining treatment. We examined the relationship between JSW and cartilage quality in 60 patients undergoing total knee arthroplasty to assess its accuracy in representing cartilage degradation. Radiographic JSW was recorded, whereas the unaffected compartment of each tibial plateau was examined postoperatively using Collins, Mankin, and Kellgren and Lawrence scores. No correlation was seen between visual or histologic grading and JSW. Histology more accurately represented cartilage quality, yet it is impractical to obtain preoperatively; thus, JSW is the main mode of assessment. However, using JSW solely to indicate unicompartmental knee arthroplasty may overlook disease in apparently unaffected compartments.
全膝关节置换术是治疗骨关节炎的常用方法，尽管单髁膝关节置换术常用于保留未受影响的关节间室。关节间隙宽度（JSW）是决定治疗方法的主要因素。我们研究了 60 例全膝关节置换术患者的 JSW 与软骨质量之间的关系，以评估其在代表软骨降解方面的准确性。记录了放射学 JSW，而在术后使用柯林斯（Collins）、曼金（Mankin）和克里格伦和劳伦斯（Kellgren and Lawrence）评分对每个胫骨平台的未受影响的关节间室进行了检查。视觉或组织学分级与 JSW 之间没有相关性。组织学更准确地反映了软骨质量，但在术前获得是不切实际的；因此，JSW 是主要的评估方式。然而，仅使用 JSW 来指示单髁膝关节置换术可能会忽略明显未受影响的关节间室的疾病。
