About
J. Christoph Katthagen is an orthopedic researcher whose work centers on the biomechanics of joint stability, with particular expertise in shoulder instability and knee ligament function. His research has significantly advanced understanding of glenohumeral joint mechanics, challenging longstanding clinical assumptions about how shoulder instability should be assessed and treated. Most notably, his 2021 study demonstrating that glenoid concavity exerts a greater influence on shoulder stability than defect size alone has garnered 47 citations and reshaped how surgeons conceptualize bony glenoid defects — shifting focus beyond simple threshold-based measurements toward the geometry of the joint surface itself. Complementing this work, his investigation of glenolabral articular disruption lesions identified these injuries as independent biomechanical risk factors for recurrent instability. Katthagen has also made meaningful contributions to knee biomechanics, with his 2023 study on anteromedial rotatory instability — already accruing 42 citations — clarifying the respective roles of the ACL and superficial medial collateral ligament. His cadaveric robotic-based research methodology reflects a rigorous, translational approach that bridges laboratory findings with clinical decision-making, making his work particularly valuable to orthopedic surgeons and sports medicine researchers alike.
