HSS Presents New Research at the AAOS 2022 Annual Meeting
At this year’s American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting, HSS physicians and scientists presented exciting new research related to clinical advancements for care and patient outcomes in orthopedics.
Highlights include gender and health disparities research in treating severe carpal tunnel syndrome and patient satisfaction related to hospital experience after knee or hip replacement; innovations in rotator cuff repair and the role of cell therapy; timelines for a patient’s return to activity after surgery to correct progressive collapsing foot deformity (PCFD); the use of biomechanics to improve joint replacement outcomes; new imaging technology to help guide the management of adolescents with scoliosis; a novel anterior cruciate ligament (ACL) reconstruction technique performed in children and adolescents at high risk for re-tears, and more.
An HSS study led by Scott J. Ellis, MD, foot and ankle surgeon, and colleagues, provides attainable goals for return to sports and related physical activities for patients who have undergone procedures to correct progressive collapsing foot deformity (PCFD), a severe musculoskeletal pathology that can drastically inhibit a patient’s daily function. Study data will be used to provide patients with realistic expectations and timelines to resume activities post-surgery and as a resource at the time when surgery is being discussed.
A thought leadership piece by Scott A. Rodeo, MD, sports medicine surgeon, discusses innovations in rotator cuff repair, specifically the role of cell therapy, and how the HSS Center for Regenerative Medicine has a robust research program that is investigating the basic cellular and molecular mechanisms of healing damaged tissue.
HSS research led by Duretti Fufa, MD, hand and upper extremity surgeon, suggests males presented with more severe carpal tunnel syndrome and were offered surgery more often than females with the condition. The study adds to a growing body of research by HSS investigators examining gender, racial/ethnic and socioeconomic disparities in diagnoses, treatment approaches and outcomes in a range of musculoskeletal conditions, including hip and knee replacement, lupus and rheumatoid arthritis.
A collaborative HSS study that included Susan M. Goodman, MD, rheumatologist, and Mark P. Figgie, MD, chief emeritus of the Surgical Arthritis Service, found that Black patients were less likely than white patients to be completely satisfied with the process of care following knee or hip replacement. Socioeconomic status was not found to play a role in patient satisfaction. The researchers reviewed the Press Ganey survey responses of more than 4,600 patients who had surgery at HSS from July 2010 to February 2012. Individuals having a primary knee or hip replacement who resided in New York, New Jersey or Connecticut were included in the study. Although Black patients indicated they were less satisfied with the process of care right after surgery, there was no difference in satisfaction with their joint replacement outcome. More research is needed to investigate other factors, such as perceived staff courtesy and baseline pain and function, to understand why disparities exist to achieve a high level of patient satisfaction for everyone.
In a study comparing outcomes of a modern cementless knee implant to the standard knee implant that requires bone cement for fixation, HSS hip and knee surgeons Geoffrey H. Westrich, MD, Brian P. Chalmers, MD, and colleagues found no difference in hospital length of stay, complications, hospital readmission within 90 days of surgery, or rates of revision surgery at two-year patient follow-up. With respect to time spent in the operating room (OR), researchers found that using the cementless implant reduced OR time by 25%, saving an average of 27 minutes.
HSS investigators present new research related to biomechanics and orthopedic surgery, highlighting the unique relationship surgeons have with the engineers to promote the highest quality in patient care and advancing joint replacement for the future. Three studies focus on how to optimize total knee arthroplasty (TKA) surgery using biomechanics and computer modeling, while another study discusses how three-dimensional (3-D) modeling can improve total hip arthroplasty (THA).
A collaborative study by Roger F. Widmann, MD, chief of the Pediatric Orthopedic Surgery Service at HSS and Howard J. Hillstrom, PhD, a biomechanical engineer at HSS, found that a technique called 3dMD, which uses an array of highly sensitive cameras and can image the entire body in a fraction of a second, generates extremely accurate and reliable models of the torso that can guide the management of adolescents with scoliosis.
HSS research by Daniel W. Green, MD, MS, FAAP, FACS, pediatric orthopedic surgeon and Frank A. Cordasco, MD, MS, sports medicine surgeon, evaluated the safety and efficacy of performing a lateral extra-articular tenodesis (LET) using a modified Lemaire technique (MLT) in conjunction with an ACL reconstruction in children and adolescents who are at an increased risk for a failed ACL reconstruction. Findings revealed the technique was associated with favorable patient-reported outcomes, high return to sports participation and low ACL re-tear rate.
