Patellofemoral Center


What if you didn’t have to live with knee pain?

Patellofemoral injuries and conditions like “runner’s knee” and dislocations can affect anyone and cause debilitating pain or instability of the kneecap (patella) without proper treatment.

The physicians at the Patellofemoral Center at HSS specialize in the management of kneecap pain and deterioration, as well as the surgical interventions that can help you heal and regain mobility. Using the latest technology and increasingly less invasive methods, our specialists offer their many years of experience diagnosing and treating patients to provide optimal care for your specific needs.

Patellofemoral disorders, also known as kneecap disorders, refer to pain and instability issues arising from a variety of sources in the patellofemoral joint. Some common examples include anterior knee pain, osteoarthritis and recurrent dislocations or subluxations. These disorders are multifactorial in etiology and can greatly inhibit patients from maintaining their active lifestyles. Furthermore, these conditions affect patients of a wide range of ages and activity, although this population is predominantly female. Patients, physicians and physical therapists find the diagnosis and treatment of these conditions extremely challenging. Currently, patients with anterior knee pain, instability and arthritis have great difficulty understanding their problem and finding the correct clinician to treat their pathology. Many orthopaedic caregivers see these conditions frequently in their offices, though treatment is extremely variable.

Our group addresses the current lack of formalized research into patellofemoral disorders, treatments and outcomes. Our Patellofemoral Center focuses on clinical outcome studies in order to evaluate current surgical techniques as well as develop new ones and improve patient outcomes. The Center has taken a comprehensive approach to investigating patient outcomes in a variety of patellofemoral disorders and treatment procedures. By utilizing a combination of prospective, retrospective, and biomechanical projects our group assesses the efficacy of current procedures and improves upon them to develop even better treatment options. The Patellofemoral Center is also focused on conducting collaborative research efforts with other institutions in the form of multi-center studies in order to maximize the quality and power of the patellofemoral patient data available. The comprehensive research efforts of the Patellofemoral Center play a critical role in improving the quality of life of the many patients suffering from knee pain and instability.

The specific areas of investigation include:

  1. Analysis of factors that may help predict failure of patella stabilizing surgery
  2. Comparison of surgical versus non-surgical treatment in first time dislocators with open growth plates
  3. Evaluation of isolated medial patellofemoral ligament reconstruction to treat instability in the knee
  4. Evaluation of the effect of current surgical techniques on contact mechanics and pressures of different trochlear and patellar morphologies
  5. Evaluation of juvenile particulated cartilage to improve severe cartilage defects in the patella.
  6. Determining the effect of patellofemoral surgery on patella vascularity
  7. Measuring outcomes and quality of life in patients undergoing PFJ arthroplasty
  8. Determining outcomes including return to sport after MPFL reconstruction
  9. Evaluating tibial tubercle transfers in the management of patellar pain and arthritis

Support for our center helps us carry out our research program. Specific areas that can be supported include:

  1. Clinical research personnel including research assistants, coordinators, and biostatisticans
  2. Engineering support including biomechanical analysis, robotic testing, TekScan sensors, 3D printing, and cadaveric specimens
  3. Imaging such as MRI, ultrasound and x-rays and histology
  4. Advanced technologies including registry platforms and software programs that streamline data entry, storage, and analysis
  5. Research staff and technologies required to facilitate large multi-institution studies
