Randomized Controlled Trial Comparative Study
Effectiveness of continuous versus single injection femoral nerve block for total knee arthroplasty: A double blinded, randomized trial.
Effective analgesia following total knee arthroplasty (TKA) is important for maximizing patient satisfaction, early participation in physical therapy and reducing the hospital stay. This trial compared continuous catheter femoral nerve block (cFNB) to single injection femoral nerve block (sFNB) in terms of analgesia, opioid consumption, and participation in physical therapy and associated side effects. ⋯ sFNB block provides equal pain relief compared with cFNB, after TKA with no significant difference in opioid consumption, hospital stay, physical therapy outcomes or associated side effects.

Until now, there has been a lack of in vivo analysis of the correlation between bony morphological features and laxity values after an anterior cruciate ligament (ACL) injury. ⋯ A higher antero-posterior laxity at 30° and 90° of flexion was found in those with a lateral tibial slope <5.5°.
