Total knee arthroplasty is one of the effective methods for the treatment of joint disease, which can effectively relieve knee pain, restore function and improve the quality of life. The goal of total knee arthroplasty is to relieve pain, restore function and obtain a long service life. Whether total knee arthroplasty can obtain good alignment is very important for the postoperative recovery of patients. The alignment of lower limb sagittal position is of great significance for evaluating whether the crowd is straightened or not, and can also evaluate and guide the TKA in sagittal position. At present, there are few studies on the sagittal position of the lower limb, and there is no clear definition of whether the lower limb is extended in the sagittal position. At the same time, there is no clear method to evaluate whether the lower limb is extended in the sagittal position in normal people and patients with OA. Therefore, it is urgent to develop a classification standard for the sagittal extension of the lower limb, which can be used in clinical evaluation and TKA operation evaluation. This study will be carried out in the first medical center of the Chinese PLA General Hospital, and a total of about 400 people are expected to be enrolled.",[59,60,61],"OA","TKA","EOS","NOT_YET_RECRUITING","2024-08-04",{"date":65,"type":66},"2024-08-06","ACTUAL",{"date":68,"type":54},"2024-09-01",{"date":70,"type":54},"2026-09-01",{"name":5,"class":6},1]
