Once again the Patellofemoral Foundation has generously supported the efforts of the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) to encourage research and expertise in the field of patellofemoral disorders. The Patellofemoral Research Excellence Award for 2009 has been won by C. Benjamin Ma and his colleagues Choongsoo Shin, Dana Carpenter and Sharmila Majumdar from the USA for their investigation of patellofemoral joint kinematics in anterior cruciate ligament deficient and reconstructed knees. The award consists of an honorarium whereby the research was presented at the Biennial ISAKOS meeting in Osaka, Japan and may be published in the Arthroscopy journal. For both this award and the Travelling Fellowship Awards, the number and quality of applications has increased substantially compared to two years ago, reflecting the success of the Patellofemoral Foundation in encouraging research and interest in disorders of the patellofemoral joint. ISAKOS is very grateful for the ongoing support of the Foundation. — Julian Feller FRACS Chair, ISAKOS Knee Committee

The Patellofemoral Foundation (PFF) Board of Directors met in San Francisco at the American Academy of Orthopedic Surgeons meeting on March 6, 2008. Representatives from our major benefactor, Smith and Nephew Endoscopy, attended as well as Lieve Van den Berghe, Vice Preident of DJO International and organizer of the Patellofemoral Consensus Group. The AAOS meeting was a great opportunity for Patellofemoral Board Members to fulfill part of our mission to enhance awareness of patellofemoral problems and provide focused educational opportunities for health care professionals about prevention and proper care of patients and athletes with patellofemoral pain and instability.
Patellofemoral General Agreement Statement from the PFF/ IPSG Consensus meeting sponsored by DJO International on March 6, 2008
- Focal loading can be a cause of PF pain.
- Overuse or at times cyclical overload of soft tissue or bone areas may explain the unusual and sometimes ill defined nature of anterior knee pain in some patients (Dye theory of envelope of load acceptance) Treatment should establish load reduction.
- Patellofemoral imbalance (including but not limited to malalignment) may cause pain by virtue of cyclical soft tissue and/or bone overload.
- Focal supraphysiological loading can, in some patients, be a cause of PF pain.
- Loss of vascular homeostasis (e.g. hypervascularity, ischemia, osseous hypertension) may be associated with anterior knee pain.
- Structural damage of articular cartilage does not always result in anterior knee pain. However, there is growing evidence that a subset of patients with chondral lesions may have a component of their pain related to that lesion.
There are many alternatives for non-operative PF pain treatment that should be considered some of which may include medications that affect neural pain transmission.
History, exam, imaging and response to treatment (differential injection, specific unloading, medication and multidisciplinary evaluation) should correlate well and be consistent in order to localize pathology and to make a precise diagnosis. Treatment should be developed based on the most precise diagnosis possible. Persistence of pain may be related to inaccurate appraisal of the cause of pain and/or inappropriate treatment decisions, patient non-compliance or complications of surgical treatment.
A patient’s active participation and understanding in his/her treatment is necessary for optimal results.
PFF/ISAKOS Travelling Fellowship Facts
Each year Patellofemoral Foundation (PFF) in conjunction with the International Society for Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) and the International Patellofemoral Study Group (IPSG) selects a young orthopedic surgeon with strong academic credentials and interest in pursuing an academic career related to the patellofemoral joint to be awarded a PFF/ISAKOS Travelling Fellowship.
The physician travels to various medical sites around the world to learn more about patellofemoral disease and how well respected expert physicians, surgeons and therapists are treating it. At each site the travelling fellow participates in patellofemoral research, patellofemoral surgical procedures, patient management or cadaver dissections in order to broaden their knowledge of the disease. The knowledge learned by the travelling fellow is invaluable and is then passed on to contemporaries, and patients.
The Travelling Fellow’s expenses are reimbursed by PFF. The physician is selected from a highly competitive international group of young orthopedic surgeons. Since 2004 Travelling Fellows have been from Belgium, France, Germany, Japan and the United States.

2011 Travelling Fellows
2010 Travelling Fellows
The aim of the Patellofemoral Travelling Fellowship is to promote better understanding and communication regarding patellofemoral pain. A stipend is provided by the Foundation to permit visits to several centres worldwide that offer opportunities to learn about the complexities of patellofemoral pain. This year four surgeons will be given the opportunity to benefit from this fellowship. Philip Schoettle from Germany, Petri Sillanpaa from Finland and Christian Lattermann from the USA will travel with Nicola Maffulli from England acting as their “godfather.”
Traveling Fellow Elvire Servien Visits US and South Africa for Further Study
As part of her traveling fellowship, Elvire Servien of Lyon, France visited three different surgeons in two countries on two different continents. Her report is provided below:
In June of 2009, I went to the United States to meet Dr. John Fulkerson of Farmington, CT and Dr. Anthony Schepsis of Boston, MA. I saw different surgeries, including and MPFL procedure and Dr. Fulkerson’s osteotomy. But I also saw many patella-disorders I usually do not see in my practice. Indeed, when experiencing anterior knee pain in France, patients are referred to the physician for a rehabilitation protocol. We went to the lab with Dr. Fulkerson with his fellow and did an MPFL knee dissection on a cadaver. I also saw several antero-medialization osteotomies with a repeat of the anteromedial tibial tubercle transfer with Dr. Schepsis. The second interesting point was a very high rate of patients with previous lateral retinaculum release ( two or three recurrent procedures) coming to see a “patella surgeon expert.” With Professor Schepsis, the dynamic CT-scan was a very interesting exam and was performed in order to analyze patello-femoral tracking during flexion.
My second destination was South Africa , where I visited Dr. Spike Erasmus. I saw his technique for MPFL reconstruction and had an extensive discussion with him about MPFL isometry and graft fixation. The fellowship ended with an International PF Study Group meeting and fantastic Sabi Sabi
Dr. Christina Stukenborg-Colsman, Associate Professor of Orthopedic Surgery at the University of Hannover, Germany, was awarded the 2007 PFF/ISAKOS patellofemoral travelling fellowship a t the May 2007 ISAKOS meeting in Florence Italy.
Dr. Stukenborg-Colsman visited with Dr. Fulkerson in July 2007. The following picture shows a dissection of the MPFL and an anteromedial tibial tubercle transfer ostemotmy performed on a cadaver knee during Dr. Stukenborg-Colsman's visit.

With the support of DJOrtho, Dr. Almqvist organized an international consensus validation meeting on patellofemoral pain in Florence on May 26, 2007.
Dr. Joson Koh was sponsored by the Patellofemoral Foundation to do educational travel regarding the patellofemoral joint, as the 2004 Travelling Fellow. He visited with Dr. Donald Fithian in San Diego, Dr. Chris Ackroyd and Dr. Andrew Aims in the United Kingdom and attended the 2005 meeting of the International Patellofemoral Study Group (IPSG).
Patellofemoral Foundation Funded Research
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.
Computational Comparison of Tibial Tuberosity Anteromedialization vs. MPFL Reconstruction for Patellofemoral Instability

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.

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.

Patellofemoral Foundation Board of Directors meeting with Jack Bert, incoming president of the Arthroscopy Association of North America (AANA), in San Francisco on March 6, 2008. The Board of Directors welcomed Jack Bert, incoming president of the Arthroscopy Association of North America(AANA), to the meeting and discussed a strategic alliance of the PFF with AANA to promote education of orthopedic surgeons about the patellofemoral joint. A proposal regarding this relationship was submitted to the AANA Board of Directors At its Board of Directors meeting April 2008, The Arthroscopy Association of North America (AANA) approved a formal relationship with the Patellofemoral Foundation (PFF) as a way of fostering and promoting patellofemoral research and education.
The shared goal is to foster and promote more and better education for AANA members regarding patellofemoral problems, as these can be complex and difficult to treat at times. PFF hopes to help AANA assume a leadership role worldwide in patellofemoral education, particularly as anterior knee pain (AKA patellofemoral pain) is very common among athletes and workers, as well as the elderly.
