Study: Outcomes for Knee Arthroscopy After TKA

A study published in the December issue of The Journal of Arthroplasty reported outcomes for patients who underwent knee arthroscopy (KA) after total knee arthroplasty (TKA). Using the PearlDiver Medicare database, 192 patients who underwent KA after TKA (TKA + KA) were identified and matched 3:1 to 571 TKA patients who did not undergo KA (TKA – KA). The main endpoints were revision for infection and all-cause revision. The TKA + KA group, compared to the TKA – KA group, had higher incidence rates of revision for infection (6.3 percent versus 2.2 percent) and all-cause revision (18.8 percent versus 5.1 percent)

Study: Outcomes for In Situ Fixation Versus Fixation After Reduction in Valgus-impacted Femoral Neck Fracture

A retrospective study published online in Injury compared femoral neck shortening (FNS) and outcomes between in situ fixation versus fixation following reduction for severe valgus-impacted femoral neck fractures. Patients underwent internal fixation with three parallel screws and either in situ fixation (in situ group, n = 28) or fixation after reduction (reduction group, n = 27). All patients achieved union. Each group had two patients who sustained avascular necrosis. At one year postoperatively, the reduction group had significantly lower FNS. At one and two years postoperatively, the reduction group had a significantly higher Harris Hip Score (HHS). FNS and HHS were negatively correlated.

Study: Long-term Scaphotrapeziotrapezoid Arthrodesis Outcomes

A study published online in HAND assessed 10-year outcomes in patients who underwent scaphotrapeziotrapezoid (STT) arthrodesis. Between 1995 and 2016, 58 STT arthrodeses were performed in 54 patients; mean follow-up was 120 months. In 69 percent of cases, Kirschner wires (K-wires) were used as the fixation method. Secondary procedures performed included total wrist arthroplasty (n = 5) and revision STT arthrodesis (n = 1). Four patients underwent procedures for nonunion. K-wire removal was performed in 24 patients. Opioid use within 90 days preoperatively, smoking history, race, comorbidity count, and BMI were not correlated with increased reoperation risk.

Study Analyzes Correlation Between Tendon Gap Size and PROs in Achilles Tendon Rupture

A study published in the November issue of The Bone & Joint Journal observed that increased gap size in patients with Achilles tendon rupture (ATR) who underwent functional rehabilitation was associated with lower patient-reported outcomes (PROs). A total of 82 patients (mean age, 51 years) with completed ATR scores (ATRS) were evaluated. Mean follow-up was 20 months after injury, at which time the mean ATRS was 76. An inverse association was observed between gap and ATRS.

Study: Changes in Pelvic Incidence After Spinal Deformity Correction with S2-alar-iliac Screws

A retrospective study published online in the European Spine Journal reported changes in pelvic incidence (PI) in patients who underwent spinal deformity correction with S2-alar-iliac screws. Sixty-eight patients (82.3 percent were female) were stratified by preoperative PI: high PI (H-PI), ≥ 60 degrees; normal PI, 41—59 degrees; and low PI, ≤ 40 degrees. The average change in PI was 46 degrees. Twenty-five patients (36.8 percent) had a PI change ≥ 6 degrees; H-PI patients were the most likely to experience significant PI changes. Pelvic tilt, lumbar lordosis (LL), and PI-LL mismatch significantly improved in patients with a PI change ≥ 6 degrees, as well as some subgroups.
