Study Compares Outcomes Between TKA Inserts
A study published online in Knee Surgery, Sports Traumatology, Arthroscopy observed comparable outcomes between ultra-congruent (UC) versus posterior cruciate ligament-stabilized (PS) inserts in PCL-sacrificing total knee arthroplasty (TKA). Sixty-six primary knee osteoarthritis patients were randomized to receive either UC or PS inserts. Preoperative Knee Society Score (KSS) and isokinetic performance did not differ between the groups. Both groups demonstrated gradual KSS improvements, with no significant differences observed during follow-up. Peak extension and flexion torque values normalized to body weight were similar at three, six, and 12 months postoperatively.

| Study Measures Predictive Value of Supervised Machine Learning Algorithms for TSA Satisfaction
A study published online in the Journal of Shoulder and Elbow Surgery detailed the development of supervised machine learning (SML) algorithms to predict two-year total shoulder arthroplasty (TSA) satisfaction. Five SML algorithms were trained. Of 413 TSA patients, 331 (82.6 percent) were satisfied two years postoperatively. When assessing the independent testing cohort not used to train the algorithms, the support vector machine model had the best performance. The most significant factors for predicting satisfaction were baseline Single Assessment Numeric Evaluation score, exercise and activity, workers compensation status, diagnosis, symptom duration prior to surgery, BMI, age, smoking status, anatomic versus reverse TSA, and diabetes.

| Study: Which Skin Suture Pattern Is Associated with Greatest Incision Perfusion After Ankle Surgery?
A randomized clinical trial published in the October issue of the Journal of Orthopaedic Trauma compared five skin suture patterns in ankle fracture surgery patients to determine which allowed for the greatest incision perfusion. Seventy-five patients were stratified by suture type: simple, vertical mattress, horizontal mattress, Allgöwer–Donati (AD), or running subcuticular (n = 15 in each group). The mean incision perfusion and mean perfusion impairment were both assessed. Mean incision perfusion was significantly better in the running subcuticular group compared to the other cohorts; mean perfusion impairment was significantly lower for this group as well compared to all the other groups, except AD.

| Study Reviews Normal Pediatric Wrist Development
A retrospective study published in the October issue of the Journal of Pediatric Orthopaedics analyzed normal geometric wrist development in children and adolescents. Radiographs of 896 children aged one to 16 years with normal wrists were stratified by yearly age and sex. The ulna minus variance dominated in this patient cohort. Steady increases during growth were observed in radial height and inclination and radiocarpal angle; expected values were reached at the start of the pubertal growth spurt. Carpal height continuously increased, but carpal height ratio was not different from adults. Volar tilt did not develop until 12 years.

| Study Measures Value of MRI to Forecast Spinal Cord Injury Outcomes
A study published in the October issue of the European Spine Journal evaluated the correlation between MRI findings and cervical spinal cord injury outcomes. A systematic review yielded six articles eligible for inclusion. In two of three studies, the maximal spinal cord compression was predictive of poor neurological outcome. Intradural factors associated with poor neurological recovery included length of the cord edema, intramedullary hemorrhage, and the length of intramedullary hemorrhage.

AAOS Presidential Symposium: The Goal Is Value
This article is the final installment of a three-part series recapping the Presidential Symposium that took place on May 27 titled “Successful MSK Care in the New Age: It’s All About Value and Outcomes,” during which Elizabeth Teisberg, PhD, provided a viewpoint from the outside addressing issues facing orthopaedic surgeons. Dr. Teisberg, who holds a PhD in engineering from Stanford University, has been involved in initiatives in many countries to reengineer the way health care, including orthopaedic surgery, is delivered.
