Study Compares Clinical and Functional Outcomes of Isolated versus Full Component Revision TKA for Aseptic Loosening
The Journal of Arthroplasty published a retrospective cohort study comparing the outcomes of aseptic revision of both femoral and tibial components versus only one loose component of total knee arthroplasty (TKA). Outcomes included surgical complications, time to prosthesis failure, and functional outcomes. A total of 238 TKA patients had a mean follow-up time of 61 months. Of the 105 patients undergoing full revision, 9.5 percent had subsequent prosthesis failure compared with 14.5 percent of isolated revision patients. No significant differences were noted between groups in respect to surgical complications or clinical results five years postsurgery.
Study: Incidence and Risk Factors Associated with Stress Fractures after Periacetabular Osteotomy
The Bone & Joint Journal published a study online characterizing the incidence and risk factors associated with stress fractures following periacetabular osteotomy (PAO). The retrospective review of 331 patients undergoing PAO for developmental dysplasia of the hip collected pelvic radiographs and demographic and surgical data with a minimum one-year follow-up Overall, 56 patients experienced stress fractures, and 86 percent of those patients healed without intervention. Stress fractures occurred more frequently in females and older patients. Seventy-six percent of patients with stress fractures had healed osteotomies at the one-year follow-up, compared to 96 percent of patients without stress fractures.
Study: Comparing Low- or High-Molecular-Weight Hyaluronate versus Physical Therapy for Shoulder Tendinopathy
A randomized controlled study published in the Clinical Journal of Sports Medicine compared the effects of subacromial high- or low-molecular-weight hyaluronate injection with physical therapy (PT) in shoulder tendinopathy. Researchers administered a 20-mg injection of hyaluronate and 10 sessions of physiotherapy and exercise. Patients were randomized to high-molecular-weight (n = 27), low-molecular-weight (n = 28) hyaluronate, or just PT (n = 24). Compared to just PT, hyaluronate injections were more effective in controlling pain, decreasing disability, increasing range of motion, and improving the quality of life. Reported pain at the injection area was less likely in those receiving low-molecular-weight hyaluronate.
Study: Outcomes and Return to Sport Rates with Accelerated Rehabilitation after Arthroscopic Ankle Lateral Ligament Repair
The Orthopaedic Journal of Sports Medicine published a case series online that included 23 ankles of 22 patients undergoing arthroscopic ankle lateral ligament repair (ALLR) for chronic lateral ankle instability with a three-day postoperative ankle immobilization and proactive early weight bearing. Clinical outcomes included pre- and postoperative instability and pain symptoms, anterior drawer distance on stress radiograph, and return to sport (RTS). Instability and pain improved in all patients postsurgery. Comparing pre- and postsurgery measurements, mean anterior drawer distance significantly improved from 8.2 mm to 4.4 mm, respectively. Overall, 75 percent of patients achieved RTS at eight weeks postoperatively.
Study: Survival and Complications in Daytime versus Overnight Digit Replantation
The time of surgery for digit operations was not associated with replantation success, according to a study published online in JAMA Network Open. Outcome measurements included number of complications and duration of surgery with a minimum one-month follow-up. Data were retrospectively collected from 98 patients and 147 digits. The overall success rate was 55 percent. Overnight replacements (between 4 p.m. and 7 a.m) were associated with 0.4 fewer complications and 90.7 minutes shorter operative times compared with daytime replacements. Results also indicated that, regardless of surgical time, there were no significant differences in digit survival.
RJOS President Mary K. Mulcahey, MD: ‘Be Intentional, Be Visible, and Be Fierce’
Current president of the Ruth Jackson Orthopaedic Society (RJOS) Mary K. Mulcahey, MD, FAAOS, FAOA, urged attendees of the RJOS Annual Meeting on March 22 in Chicago to be fearless in the pursuit of their goals. Dr. Mulcahey emphasized owning your own narrative and having a clear sense of purpose when defining and striving toward your career goals. She encouraged attendees to “Be intentional, be visible, and be fierce. Go after what you want. We’re here to support you.”
