In a prospective evaluation of 165 consecutive patients (228 knees), intraoperative evaluation of the knees was performed at the time of total knee arthroplasty. Each of the three knee compartments was independently graded for arthritic changes depending on the extent of articular degeneration visualized. Patients were believed to be suitable candidates for unicondylar knee arthroplasty (UKA) if they fulfilled the Kozinn and Scott criteria. Specific attention was given to patient age, weight, preoperative range of motion, angular deformity, as well as the extent of intraoperative cartilage erosions seen. Thirty-five knees (15%) were candidates for UKA based solely on inspection of the articular surfaces at the time of surgery. Further analysis revealed that of these 35 knees, 22 failed to meet the other selection criteria. Thus, of the original 228 knees, only 13 knees (6%) fulfilled all of the stringent selection requirements and were considered suitable candidates for UKA. With proper patient selection, the number of UKAs performed could become relatively small.
在一项对165例连续患者（228个膝关节）的前瞻性评估中，在全膝关节置换术时对膝关节进行了术中评估。根据可见的关节退变程度，对三个膝关节间室中的每一个进行关节炎变化的独立分级。如果患者符合科津（Kozinn）和斯科特（Scott）标准，则被认为是单髁膝关节置换术（UKA）的合适候选者。特别关注患者年龄、体重、术前活动范围、角畸形以及术中所见软骨侵蚀的程度。仅根据手术时关节表面的检查，有35个膝关节（15%）是UKA的候选者。进一步分析显示，在这35个膝关节中，有22个未满足其他选择标准。因此，在最初的228个膝关节中，只有13个膝关节（6%）满足所有严格的选择要求，并被认为是UKA的合适候选者。通过适当的患者选择，进行的UKA数量可能会相对较少。
