The Impact of Preoperative Muscle Mass on Postoperative Functional Outcomes Following Total Knee：An Investigation under a Criteria-Based Protocol

Key Points

• This research aims to analyze the relationship between preoperative muscle mass and postoperative functional outcomes following total knee arthroplasty.
• Applied a criteria-based protocol for early mobilization after total knee arthroplasty
• Assessed preoperative muscle mass levels
• Evaluated postoperative functional outcomes
• Findings indicate a correlation between higher preoperative muscle mass and improved postoperative function
• Patients with lower muscle mass experienced delayed recovery
• Implications suggest monitoring muscle mass before surgery may enhance rehabilitation outcomes
