Randomized Study Assesses Adductor Canal Block with IPACK for TKA
A randomized study published in The Journal of Arthroplasty found that an adductor canal block (ACB) plus an infiltration between the popliteal artery and capsule of the posterior knee (IPACK) block during total knee arthroplasty (TKA) is safe and led to a small but statistically significant improvement in immediate postoperative pain compared to ACB alone. In total, 120 patients received either ACB alone, IPACK alone, or ACB plus IPACK. ACB plus IPACK led to the lowest pain scores within eight hours postoperatively, both at rest and with knee maximum flexion. Pain at 24 hours, function, and postoperative complications were comparable for all methods overall.

Study: Medialized versus Lateralized Implant RTSA in Pseudoparalysis with Massive RC Tear
A retrospective study published online in the Journal of Shoulder and Elbow Surgery compared outcomes with medialized versus lateralized humeral implants for pseudoparalysis in patients undergoing reverse total shoulder arthroplasty (RTSA) for repair of massive rotator cuff (RC) tear. Fifty-one patients were followed for an average of 49 months (lateral, n = 25; medialized, n = 26). Postoperative lateral humeral offset and deltoid wrapping offset were significantly larger for lateral implants, and acromiohumeral distance was larger for medialized implants. Both groups demonstrated significant improvement in active range of motion. Postoperative pseudoparalysis recovery in the medialized and lateral groups were 96.2 percent and 100.0 percent, respectively.

| Study: High Rate of Return to Sport after Hip Arthroscopy for FAI in Athletes
A systematic review published online in the American Journal of Sports Medicine reported a high rate of return to sport among athletes treated with hip arthroscopy for femoroacetabular impingement (FAI). In total, 130 studies were included, comprising 14,069 patients. Average follow-up was 29.7 months. Of 81 studies reporting return to play, the overall rate of return was 85.4 percent over a mean of six months. Forty-nine studies reported a 72.6 percent rate of return to play at preinjury level and 45 studies reported return to play was advised at three to six months postarthroscopy.

| Study: Investigating Cartilage Damage after Intra-articular Ankle Fracture
In intra-articular ankle fracture, anti-inflammatory agents may improve cartilage damage caused by inflammatory cytokines in the synovial fluid fracture hematoma (SFFH), according to an in vitro study published online in Foot & Ankle International. Cultures from 54 fractures were assessed. Cultures with SFFH from days one to two, from days three to nine, and from days 10 to 14 after fracture demonstrated increased production of cytokines, metalloproteinases, and extracellular matrix breakdown products compared to controls and cultures which received interleukin-1 receptor antagonist (IL-1Ra) or doxycycline. Adding either IL-1RA or doxycycline partially attenuated the negative effects on cartilage. Chondrocyte survival was similar overall.

| Study: Perioperative Complications in Single-position Lateral versus Supine ALIF
Single-position lateral decubitus anterior lumbar interbody fusion (ALIF) with percutaneous posterior fixation led to reduced perioperative complications compared to supine ALIF with percutaneous pedicle screws for degenerative pathologies, according to a retrospective study published online in The Spine Journal. In total, 321 patients were evaluated (lateral, n = 124; supine, n = 197), including 248 propensity-matched pairs. Lateral ALIF significantly reduced operative time (132.95 versus 261.79 min), blood loss (120.44 versus 224.29 mL), length of stay (2.07 versus 3.47 days), and ileus rates (0.00 versus 6.45 percent) compared to supine ALIF. Radiation dose, 90-day readmissions, and other complications were similar between groups.
