Assessment of Biomarkers Associated with Joint Injury and Subsequent Post-Traumatic Arthritis
Abstract
The overall objective of this research effort is to identify biomarkers following articular fracture that may be predictive of the development of post-traumatic arthritis (PTA). PTA is a clinically important complication of joint injury with life-long effects for the patient. While PTA can occur rapidly after moderate to severe articular injuries, not every patient will go on to develop this condition. There are no effective screening methods to determine who is at risk. This proposal includes both a clinical observational study and a series of murine experiments, both with the goal of identifying biomarkers that are associated with development of PTA. Patients with knee joint fractures will be enrolled, and we will collect serum, urine, and synovial fluid early after injury. Radiographic imaging will be performed early after injury, again at 18 months, and analyzed to determine which patients developed PTA from those who did not. We will assess the ability of identified biomarkers in serum, urine, and synovial fluid to predict PTA following joint injury. Additionally, biomarkers will be assessed in a murine model of articular fracture using two strains in which one strain develops PTA and the other does not. Comparison of the human and mouse response to knee joint fracture will allow assessment of the potential use of the mouse model to evaluate future therapies to prevent PTA.
