NCT04111276

Brief Summary

In vivo knee kinematics will be assessed for 20 subjects that have been clinically diagnosed with substantial unicompartmental osteoarthritis (OA) by one of the surgeons of Colorado Joint Replacement; this is the location from which participants will be recruited. The objective of this study will be to analyze subjects with symptomatic unicompartmental osteoarthritis under in vivo dynamic, weight-bearing conditions using video fluoroscopy to determine if present-day OA knee braces provide separation of the femoral condyle from the tibial plateau, thus avoiding excessive loads on the degenerative compartment.

Researchers would like to retain this study data in our secure database so as to continue to add relevant, current data to our digital collection to help us work with manufacturers in the future to create better implants that last longer and will not require revision surgery. Participants will be asked if their study data may remain a part of the University of Tennessee's Center for Musculoskeletal Research data collection for use in future studies in the IC. Identifiers are automatically removed from the database upon entry into the secure server. Data shared with sponsors is de-identified.
