Function and Pain Following Knee Replacement

The goal of this interventional study is to compare pain management techniques (femoral nerve block, intra-articular block, none) in TKA patients. The main questions it aims to answer are: * Are there differences in postoperative outcomes? * Does preoperative quadriceps muscle strength predict early functional ability? Participants underwent TKA and assessments. Researchers compared pain management techniques to assess effects on postoperative outcomes and identified the importance of preoperative quadriceps muscle strength as a predictor of early functional ability. Further research is required to refine postoperative pain management strategies.
