PFF Funded Research

The PF Foundation Board of Directors has awarded a $5000 grant to Dr John Elias at Akron General Hospital to study patella articular contact pressure alteration with lateral entry of the patella into the trochlea.

Dr Matthew Bollier, Assistant Professor of Orthopedic Surgery at the University of Iowa has been awarded a $5000 grant from the Patellofemoral Foundation to support a research project entitled: "The effect of patellar height on patellofemoral contact pressure and area after medial patellofemoral ligament reconstruction: a finite element analysis."

John Elias and Andrew Cosgarea have reported new and exciting results from their PFF funded research. In a computer model of knees with dysplastic trochleas, they have established that proximal realignment (MPFL reconstruction) creates greater patellofemoral articular loads than tibial tubercle transfer. This important work helps to further clarify the need for distal alignment in controlling patellar instability when the trochlea is flat and there is lateral tracking of the patella. Read More

Purpose: The purpose of this study was to evaluate the effect of surgical reinsertion of the medial patellofemoral ligament (MPFL) to the adductor tubercle compared with conservative treatment in patients with primary dislocation of the patella. Methods: Eighty patients with primary patella dislocation were included in the study. Delayed arthroscopy (mean, 50 days after injury) was performed to assess cartilage injury and status. During arthroscopy, patients were randomized to surgical reinsertion of the MPFL or to conservative treatment. Conservative treatment was use of a brace with 0° to 20° motion for the first 2 weeks after dislocation. Patients were followed up for 2 years. The incidence of recurrent patella dislocation was recorded along with the clinical Kujala scores and Knee Injury and Osteoarthritis Outcome Scores. Results: The redislocation rates were 17% and 20% in the operative and conservative treatment groups, respectively (P= not significant). Kujala scores were 85 and 78 in the operative and conservative treatment groups, respectively (P = .07). The patella stability subscore was significantly higher in the operative group. No difference in Knee Injury and Osteoarthritis Outcome Scores was found. Conclusions: Delayed primary repair of the MPFL by use of an anchor-based reattachment to the adductor tubercle without vastus medialis obliquus repair after primary patella dislocation does not reduce the risk of redislocation nor does it produce any significantly better subjective functional outcome based on the Kujala knee score. Only the specific subjective patella stability score was improved by MPFL repair compared with conservative treatment. Level of Evidence: Level I, therapeutic randomized controlled trial. Read More

The Hartman Patellofemoral Reseach Fund was established in recognition of Mr. J. William Hartman. Mr Hartman, president of Hartman Newspapers, Rosenberg, Texas, expressed unhesitating and early support of the concept and mission of the Patellofemoral Foundation with his generous Founding Benefactor pledge.  Mr. Hartman renewed his committment to Patellofemoral Foundation in July 2007 with pledge of support for the next five years. We truly appreciate his dedication to Patellofemoral Foundation's mission.

Christiansen's PFF/ISAKOS award winning research found that there is no advantage to acute repair of the medial PF ligament after acute dislocation of the patella.
