— ​Patrick K. Horst, MD​

Orthopaedic surgeon Patrick K. Horst, MD, has joined the University of Minnesota Health orthopaedics team. Horst, a graduate of University of Minnesota Medical School, returns to Minnesota after completing his residency in orthopaedic surgery at Stanford University and a fellowship at University of California, San Francisco. Horst specializes in partial and total knee and hip replacement procedures, including anterior and posterior approaches to total hip arthroplasty. He has published studies on interventions that resulted in improvements in patient mood and activity level following knee surgery. In his research, he plans to assess the relationship between pre-surgical counseling and patient outcomes following hip replacement surgery.

Research partnership aims to improve joint analysis

University of Minnesota Health orthopaedic specialists and University of Minnesota’s Center for Magnetic Resonance Research (CMRR) have joined forces in a research partnership aimed at better identifying when a joint might benefit more from repair or replacement. As part of the CMRR Musculoskeletal Research Program, clinical and basic scientists are designing MRI sequencing algorithms that can quantify the amount of articular cartilage remaining at the ends of bones. Researchers believe the new MRI technology may ultimately allow orthopaedic surgeons to determine which patients will benefit most from hip replacement and which from repair procedures. Orthopaedic surgeons believe MRI, rather X-ray, technology may provide a better means of determining the extent of joint damage. University of Minnesota Health orthopaedic surgeon Patrick M. Morgan, MD, serves as a member of the research team, and the research partnership has secured preliminary funding. The researchers will conduct cartilage assessment at 3 tesla with later testing of bilateral hip MRI at 7 tesla—an ultra-high resolution magnetic field strength that increases signal-to-noise ratio and spatial resolution.
