Study: Characteristics and Risk Factors of Postoperative Fever after TJA
BMC Musculoskeletal Disorders published a study investigating the characteristics and risk factors of postoperative fever (POF) after total joint arthroplasty (TJA). Overall, 2,482 patients undergoing total knee (TKA) or hip arthroplasty (THA) were respectively divided into non-fever or fever groups based on their body temperatures. POF was defined as body temperature >38 degrees Celsius. Forty-five TKA patients had fevers, and 38 percent of those had maximum temperature two days postoperatively. Six percent of THA patients had fever, of which 65 percent had maximum body temperature one day postoperatively. In both groups, high C-reactive protein was a risk factor for POF.

| Study Investigates Rates of Mortality and Perioperative Complications in Shoulder Arthroplasty Patients with a History of Stroke
Patients with a history of stroke with sequela undergoing primary shoulder arthroplasty (SA) had higher rates of perioperative complications and mortality, according to a study published in the Journal of Shoulder and Elbow Surgery. A matched cohort comprising 205 primary SA patients who sustained a previous stroke with sequela had a minimum follow-up of two years. Patients in the stroke cohort sustained 38 surgical and 42 medical perioperative complications. Subsequent incidences of death at five and 20 years postsurgery were 25.6 percent versus 14.7 percent and 92.6 percent versus 58.6 percent in the stroke and matched cohorts, respectively.

| Study: MPFL Repair after First-time Patellar Dislocation Led to Lower Redislocation Rates versus Rehabilitation
A systematic review published online in Knee Surgery, Sports Traumatology, Arthroscopy compared the rate of patellar redislocation and functional outcomes after medial patellofemoral ligament (MPFL) repair versus nonoperative rehabilitation treatment in patients with first-time patellar dislocations. A total of 25 studies and 1,361 patients were included in the review. The mean redislocation rate in the rehabilitation group was 30 percent compared with 7 percent in patients undergoing MPFL repair. Range of motion deficits were reported in 3.8 percent of patients in the rehabilitation group and 2.0 percent of MPFL repair patients.

| Study: Risk Factors of Lumbar Plexus Injury after Oblique Lumbar Interbody Fusion
The European Spine Journal published a retrospective review assessing the incidence and risk factors of lumbar plexus injury (LPI) after oblique lumbar interbody fusion (OLIF) surgery. OLIF patients (n = 110) were divided into either the group with LPI or the non-LPI group. Overall, 13 patients had short-term LPI-related symptoms, and six patients did not fully recover after one year. The anterior edge of left psoas major muscle overpassing the anterior edge of the surgical intervertebral disk on axial radiograph and narrow OLIF channel space were independently associated with LPI.

ICL Elucidates Regulatory Guidelines on Orthobiologics
In the Instructional Course Lecture (ICL) presented at the AAOS 2022 Annual Meeting titled “Orthobiologics Use and Marketing: U.S. Food and Drug Administration, Federal Trade Commission, and Ethical Compliance,” Scott Bruder, MD, PhD, founder and CEO of Bruder Consulting & Venture Group, discussed the complex regulations surrounding the use of orthobiologics. “We are now in the age of biology,” he said. Dr. Bruder called for physicians to hold themselves to a high standard, educate themselves and their patients, and encourage their peers to do the same.
