Adult Reconstruction

The Adult Reconstruction Section provides comprehensive care for patients with a wide variety of hip and knee joint-related problems. Our expert clinicians combine the latest scientific research with innovative surgical techniques to relieve pain and improve joint function, helping to transform the lives of our patients. We treat a variety of conditions, including inflammatory arthropathy and degenerative osteoarthritis, congenital and post-traumatic injuries, infections, and fractures.

In addition to our central mission of providing outstanding patient care, our faculty serve on the core academic teaching faculty of the Yale University School of Medicine. We are authors and educators actively engaged in medical research, teaching medical students, residents, fellows, and visiting guest scholars from all around the world. We built our modern division on the tradition of surgical innovation inspired by our own Kristaps J. Keggi, MD, who was the first surgeon in the United States to utilize the Direct Anterior Approach (DAA) for Hip Reconstruction at Yale in the 1970s. That technique transformed the lives of patients using minimally invasive surgery (MIS) techniques and is the standard to this day.

We embrace the latest evidence-based non-operative treatments and conservative care strategies in our offices, including targeted injection of both short and long-acting steroid medications and visco-supplement (gel) injections. We offer open and arthroscopic assisted hip preservation surgery for femoroacetabular impingement (FAI) syndrome including peri-acetabular osteotomy (PAO) and corrective osteotomies for residual congenital and childhood hip deformities. For selected patterns of avascular necrosis (AVN) without joint space collapse, we offer decompression and stem cell injection strategies for hip preservation. For adult patients with degenerative joint disease (DJD) or avascular necrosis (AVN), we perform a high volume of total hip arthroplasty (THA) and total knee arthroplasty (TKA), partial hip replacement (hip hemiarthroplasty), and partial knee replacement (unicondylar knee arthroplasty or UKA). Our surgeons perform a large volume of revision hip and knee replacement for prosthetic implant failures, peri-prosthetic fractures, and prosthetic joint infections (PJI). We are one of the most advanced total joint replacement programs in the nation. Our surgeons use the latest technologies, including computer-based digital case planning, 3D printed models, patient-specific instrumentation (PSI), custom-designed implants for complex surgeries, computer-assisted surgical navigation, tele-rehabilitation software, and supercomputers for research and innovation in implant design. These resources allow us to develop specific, individualize care plans to address even the rarest and complex cases. Our physicians publish regularly in top-rated peer-reviewed journals such as the Journal of Arthroplasty, Arthroplasty Today, the Journal of Bone & Joint Surgery, and hold appointments in groups such as the American Association of Orthopaedic Surgeons (AAOS), the American Association of Hip and Knee Surgeons (AAHKS), the American Orthopaedic Association (AOA), and the International Congress for Joint Reconstruction (ICJR).
