Platelet-rich Plasma Versus Corticosteroid Injection for the Treatment of Femoroacetabular Impingement

Platelet-rich Plasma Versus Corticosteroid Injection for the Treatment of Femoroacetabular Impingement

The purpose of this study is to compare the clinical response of intra-articular platelet rich plasma (PRP) versus corticosteroid injection in patients affected by femoroacetabular impingement (FAI).

This study will determine if PRP treatment of FAI improves (i) patient reported outcome scores and (ii) hip functional stability compared to standard corticosteroid treatment and if PRP treatment of FAI reduces (i) radiographic and (ii) biochemical markers of joint inflammation and cartilage degradation.

Inclusion Criteria:

• Patients with symptomatic FAI
• Clinical and radiographic evidence of FAI
• Patients able to provide consent to study participation
• Completion of 6 weeks of physical therapy program

Exclusion Criteria:

• Established Osteoarthritis (Kellgren-Lawrence > 3)
• Minimum joint space > 2 mm as measured on AP radiograph
• Hip dysplasia (center edge angle < 20° on AP radiograph)
• Patients with clinically significant cardiovascular, renal, hepatic, endocrine disease, cancer or diabetes
• Patients with ongoing infection including HIV and Hepatitis
• Patient with history of osteomyelitis/septic arthritis
• Anticoagulation therapy
• Patients who are pregnant or breast feeding
• Patients with systemic, rheumatic or inflammatory disease of the knee or chondrocalcinosis, hemochromatosis, inflammatory arthritis, arthropathy of the knee associated with juxta-articular Paget's disease of the femur or tibia, hemophilic arthropathy, infectious arthritis, Charcot's knee joint, villonodular synovitis, and synovial chondromatosis
• Patients taking immunosuppressant medication
• Patients with abnormal hematology or serum chemistry lab results
• Patients receiving injection to treatment knee within 2 months of study enrollment
• BMI greater than 35 or less than 20
