Inflammatory Response Following Intraarticular Fracture

The purpose of the study is to investigate a relationship between the inflammatory response following intraarticular fracture and post-traumatic osteoarthritis. The investigators plan to evaluate the inflammatory cytokine profile in knee joint synovial fluid and blood serum in patients who sustain an intraarticular tibial plateau fracture and ankle joint synovial fluid and blood serum in patients who sustain an intraarticular tibial plafond fracture. This information will be combined with radiographs and patient outcome measures to determine a correlation between intraarticular inflammatory response and post-traumatic osteoarthritis.
