Registry Analysis Compares Risk of Revision in Mobile-bearing versus Fixed-bearing TKA
An analysis of the American Joint Replacement Registry, published in the Journal of Arthroplasty, found that patients who underwent mobile-bearing (MB) total knee arthroplasty (TKA) had higher risk of all-cause revision when compared with fixed-bearing (FB) designs. Overall, 485,024 TKAs in patients aged >65 years were analyzed. Of these, 93.2 percent were FB-TKAs and 6.8 percent were MB-TKAs. Using event-free survival curves, MB-TKAs were at an increased risk for all-cause revision, with an even greater increased risk up to eight years postsurgery. However, MB-TKAs were not found to be at an increased risk of revision due to infection.

| Study Finds Increased BMI Is a Risk Factor for PJI in Patients Undergoing THA via Anterolateral Approach
A propensity score-matched analysis in Archives of Orthopaedic and Trauma Surgery compared the differences in surgical and patient-related risk factors for periprosthetic joint infection (PJI) between patients undergoing total hip arthroplasty (THA) via either a minimally invasive (MIS) anterolateral or the transgluteal-modified Hardinge approach. Based on a retrospective review, 1,495 THAs implanted through the anterolateral approach and 2,687 THAs implanted via a transgluteal-modified Hardinge approach were included in the analysis. The rate of PJI was 1.1 percent in both cohorts. For the MIS anterolateral approach, BMI ≥35 was a risk factor for PJI, and operation times ≥121 minutes significantly increased the risk of PJI for both cohorts.

| Retrospective Study Identifies Lumbar Anterior Screw Breech as a Risk Factor for Postoperative Ileus in Adolescent Idiopathic Scoliosis
Orthopaedic Surgery published a retrospective study investigating the incidence of and risk factors for postoperative ileus (POI) following corrective surgery in patients with adolescent idiopathic scoliosis (AIS). Patient demographics, lowest instrumented vertebra (LIV), number of screws, length of stay (LOS), T10–L2 thoracolumbar kyphosis and height, and L1–5 height were compared between 318 AIS patients with and without POI. Postsurgery, 42 patients developed POI. POI patients had had a significantly longer LOS, more lumbar screws, and a lower LIV. Large changes in T10–L2 and L1–5 height and lumbar anterior screw breech were risk factors for POI following corrective surgery.

| Study: Rates and Risk Factors for Local Recurrence of Giant Cell Tumor of Bone
According to a study published in Current Orthopaedic Practice, soft-tissue invasion was a risk factor for local recurrence (LR) of giant cell tumor of bone following surgical treatment. Fifty-two patients were retrospectively reviewed with a minimum four-year follow-up. All LRs occurred within the first three years, and the highest recurrence rate was observed among those with lesions of the proximal femur. In addition to soft-tissue invasion, the occurrence of pathological fracture at presentation and utilizing curettage as a method of treatment were associated with significantly higher rates of LR.
