OAA is the oldest, private orthopedic practice in the Lehigh Valley area dating back to 1970. OAA made a prominent change in the treatments of orthopedics in the region through innovative procedures by former President and Founder Dr. Peter Keblish, and thus a reputation for cutting edge excellence began.

Dr. Peter Keblish, an extremely accomplished and internationally recognized orthopedic surgeon, specialized in hip and knee replacement. He was recognized as one of the major contributors to the development of total knee replacement surgery, and in 1971, was the first surgeon in the Lehigh Valley to perform a total joint replacement procedure.

Over the years, our practice has continued to increase the number of providers, musculoskeletal specialties, and providers, while maintaining our commitment to excellent patient care.
