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. 

Research highlights include advancements in accelerating recovery after knee surgery, a preclinical study which found earlier anterior cruciate ligament (ACL) reconstruction is associated with lower risk of knee osteoarthritis, and a 40-year study demonstrating active patients who had total knee replacement are unlikely to require revision surgery in their lifetime. 

HSS Presents Innovative Research Aimed at Faster Recovery After Knee Surgery at AAOS Annual Meeting

HSS investigators presented several significant studies, three of which focused on new ways to help patients recover faster after total knee arthroplasty (TKA), also known as knee replacement surgery. 

Preclinical Study Finds Earlier ACL Reconstruction is Associated with Lower Risk of Knee Osteoarthritis 

A preclinical study by HSS investigators led by sports medicine surgeon Scott Rodeo, MD, found that earlier ACL reconstruction led to lower immune cell activity, less inflammation and fewer joint changes associated with knee osteoarthritis compared to delayed surgery.

New Study Reveals Young, Active Patients Who Have Total Knee Replacements are Unlikely to Need Revision Surgery in their Lifetime

A 40-year study by HSS researchers led by hip and knee surgeon William J. Long, MD, FRCSC, has found that active young adults who underwent total knee replacement were unlikely to require knee replacement revision in their lifetime.
