Study: Pulmonary Hypertension Linked to Post-TKA Complications and Mortality

Pulmonary hypertension is associated with increased risk of mortality and complications after total knee arthroplasty (TKA), according to a study published online in The Journal of Arthroplasty. The investigators assessed 887 patients with pulmonary hypertension (primary, n = 881; revision, n = 228). Ninety-day mortality was 0.7 percent and 4.8 percent for primary and revision surgery, nearly two-fold higher than in TKA patients without hypertension Ninety-day medical complications were 6.5 percent for primary and 14.0 percent for revision TKA. Ten-year revision was 5.0 percent and 16.0 percent, respectively.

Study: Modified McLaughlin Procedure for Chronic Locked Posterior Dislocation of the Shoulder

A retrospective study published online in the Journal of Shoulder and Elbow Surgery found favorable midterm outcomes of the Modified McLaughlin procedure for chronic locked posterior dislocation of the shoulder. Among 10 patients included in the study, the authors noted worse outcomes when the delay between injury to diagnosis was longer than six months. Mean follow-up was 59.4 months. Patients showed significant postoperative improvements in forward flexion external rotation, internal rotation, and functional assessments. Two cases with longer than six-month delays had poor functional outcomes and severe glenohumeral degenerative joint disease. No cases of recurrence, infection, or neurologic injury occurred.

Study: Characteristics and Management of Pediatric Pelvic Fractures at a Level I Trauma Center

An observational study of pediatric patients with pelvic fractures, published online in BMC Musculoskeletal Disorders, found these injuries are associated with high-impact trauma with multisystem injuries. In total, 119 cases from a single center (11 percent of pediatric admissions) were retroactively assessed (pelvic ring fracture, 91.6 percent; acetabular fracture, 8.4 percent). Compared to the conservative group, surgically managed patients tended to have more severe injury, type IV fracture, acetabular fracture, and closed triradiate cartilage. In-hospital complications and mortality were comparable between patients with closed and open triradiate cartilage. Overall mortality was 2.5 percent.

Study: Impact of Unstable Chondral Lesions on Five-year Outcomes of Arthroscopic Meniscectomy

Five-year outcomes after arthroscopic partial meniscectomy were significantly worse for patients with unstable chondral lesions, according to a study published online in Arthroscopy. Seventy-one patients with unstable lesions were compared to 47 patients without. Lesions were associated with significantly lower improvements in functional assessments of sport and recreation, pain assessments, and knee extension, as well as decreased quadriceps circumference. Rates of progressive radiographic joint space–narrowing and revision were comparable between groups.
