AAHKS Symposium: State-of-the-Art Management of Tough and Unsolved Problems in Hip and Knee Arthroplasty

Background Incompletely solved problems in hip and knee arthroplasty present ongoing practice challenges. Methods Content experts summarized treatment options and preferred treatment methods for 4 incompletely solved problems in hip and knee arthroplasty. Results The problems chosen for discussion in this symposium included 2 soft tissue problems: chronic extensor mechanism deficiency after total knee arthroplasty and abductor deficiency after total hip arthroplasty (THA), recurrent infection after a 2-stage procedure for infected THA or total knee arthroplasties, and pelvic discontinuity after THA. Conclusion The approaches outlined may provide guidance on management of these different problems. For surgeons and others in the orthopedic community interested in innovation, these challenges also present ripe opportunities to improve the care of patients with unmet needs.
