Eleven Joints, One Error
An orthopedic thesis argues that several specialties mistook population averages for patient-specific joint references.
Field notes
The programme uses a common six-question structure to compare eleven joint-specific instruments, then sorts them into three families based on the patterns found during construction. Its central workflow is to measure the loaded joint across its arc, define the functional envelope, replace a population-average reference, and address residual problems with geometry. The page reports one refuted hypothesis and no real operation planned by an instrument, while also identifying cross-specialty parallels such as hip two-position testing and the ankle Coleman block.
