The editor-in-chief also serves as chair of the AAOS Now Editorial Board. The application deadline is July 16.
Study: Cam-type FAI Is Associated with Altered Kinematics and Muscle Force Production
A systematic review published online in Arthroscopy found that patients with cam-type femoroacetabular impingement (FAI) exhibit altered sagittal and frontal plane parameters compared to control subjects. The 12 studies meeting inclusion criteria reported biomechanical data on 173 patients with cam-FAI and 177 healthy matched controls. Cam-FAI was associated with reduced sagittal plane range of motion and altered muscle force production during level gait compared to controls. Patients with cam-FAI walked at a slower pace compared to controls.
Study: Post-TKA Knee Flexion Angle and Patient Satisfaction in an Asian Population
Knee flexion angle >130 degrees after total knee arthroplasty (TKA) increased ease of high-flexion activities and patient satisfaction, according to a retrospective study of Asian patients published online in BMC Musculoskeletal Disorders. In total, 912 TKA cases in Asian patients were analyzed. Sixty-eight percent of patients achieved high knee flexion (>130 degrees) post-TKA. More than half of the high flexion group could not kneel/squat and 35 percent could not stand up from on the floor. High knee flexion, high-flexion activities, male gender, and bilateral TKA were significantly associated with patient satisfaction.
Randomized Trial Finds Comparable Long-term Outcomes for DRF Fixation Techniques
A randomized trial published online in JAMA Network Open did not find clinically meaningful outcome differences between various fixation techniques for distal radius fracture (DRF) In total, 304 patients were randomized to surgery (n = 187 [65 to volar locking plate system; 64 to external fixation with or without supplementary pinning, and 58 to percutaneous pinning]), while 117 opted for closed reduction and casting. At 24 months, between-group Michigan Hand Outcomes Questionnaire scores and pain scores were comparable.
Study: Two-stage Management of Calcaneal Fracture with Transarticular K-wire Pinning
A study published online in Foot & Ankle International found that temporary transarticular Kirschner wire (K-wire) pinning for staged calcaneal fracture treatment is safe, effective, and may decrease wound-related complications. Twenty fractures were treated with two-stage management. Temporary transarticular K-wire pinning was performed 24 hours post-injury, and then delayed ORIF (open reduction–internal fixation) was performed. At a mean follow-up of 17 months, average Böhler angle showed improvement from –22 to 25 degrees and no infections or wound complications occurred.
CDC Releases Interim Guidance on Care for Patients with Post-COVID Conditions
On Monday, the Centers for Disease Control and Prevention (CDC) released an interim guidance for health care providers regarding evaluation and care of patients experiencing post–COVID-19 conditions, including long-term illness and lingering signs and symptoms four or more weeks after SARS-CoV-2 infection. The CDC suggests that many of these conditions can be managed by primary care providers and encourages shared decision making and patient-centered management from other healthcare professionals treating patients with these symptoms.
AAOS members will soon receive the print edition of the June issue of AAOS Now, but the electronic edition is already available on the AAOS Now website. This month’s issue highlights how COVID-19 impacts athletes’ mental health, new protocols for evaluating the use of stem cells in orthopaedics, the #SpeakUpOrtho movement against harassment in medicine, and more.
