Comparative StudyFemoral Nerve Block vs Periarticular Bupivacaine Liposome Injection After Primary Total Knee Arthroplasty: Effect on Patient Outcomes.
Patients receiving femoral nerve blocks for total knee arthroplasty (TKA) have been shown to have a high incidence of postoperative falls, which has been attributed to weakening of the quadriceps muscles. Local injection of analgesic medication that allows for full motor function of the quadriceps and, therefore, better progress through inpatient physical therapy and decreased hospital stay, has been suggested as an option for postoperative pain relief. ⋯ Compared with femoral nerve block, periarticular injection of analgesia was found to quicken postoperative recovery in patients hospitalized for TKA. The use of periarticular injections in patients undergoing TKA could yield substantial cost savings given the high frequency of this procedure.

ReviewPosterolateral Corner Knee Injuries: Review of Anatomy and Clinical Evaluation.
The structures in the posterolateral corner of the knee, which stabilize the joint, are often involved in injuries to the posterior cruciate ligament. Familiar structures include the anterior cruciate ligament, posterior cruciate ligament, tibial collateral ligament, and menisci. ⋯ The purpose of this review is to highlight the posterolateral corner of the knee and injuries to its structures so that physicians can more accurately diagnose these injuries and provide appropriate treatment. Management focuses on restoring the fibular collateral ligament, popliteofibular ligament, and, in certain cases, the popliteus tendon.
