Abstract:
BACKGROUND: Artificial total knee arthroplasty in the treatment of knee osteoarthritis can effectively eradicate the late knee pain, correct deformity, improve joint function, but the use of patel a is not conducive to the recovery, and it is easy to cause postoperative complications. Therefore, patel ar lateral shift, instead of patel a minimal y invasive therapy, has attracted more and more people’s attention, which increased excel ent and good rate of operation. OBJECTIVE: To investigate the effects of patel ar turnover and patel ar lateral displacement on knee function recovery and complications of elderly patients with total knee arthroplasty. METHODS: A total of 80 knees of 40 elderly patients with bilateral knee osteoarthritis were selected. Al patients according to the random number table method were divided into two groups with 40 knees of 20 cases in each group. The patients in the study group received patel ar lateral shift operation, while the patients in the control group received the patel ar turnover. Curative effects, the recovery of knee joint function and occurrence of complications were compared between the two groups at 1 week, 3 months, 6 months and 1 year after arthroplasty. RESULTS AND CONCLUSION: No significant difference in 90° flexion time in the knee was detected between the two groups after replacement (P > 0.05). Active straight leg raising time was shorter in the study group than in the control group (P < 0.05). No significant difference in passive range of motion was detectable between the two groups at 6 months after replacement. Active and passive ranges of motion were significantly better in the study group than in the control group at various time points (P < 0.05). There were no significant differences in Visual Analog Scale pain scores and postoperative complications between the two groups (P > 0.05). These results verified that patel ar lateral displacement for elderly patients with total knee arthroplasty is conducive to early knee function recovery after surgery, and it is safe and reliable.
