Despite being one of the most commonly diagnosed causes of hind limb lameness, much controversy persists regarding the diagnosis and treatment of patellar luxation. While the diagnosis is generally easily made during an orthopedic examination, assessment of the associated limb deformities can be challenging. Precise qualification and quantification of the skeletal abnormalities contributing to the luxation is critical in planning correction of said deformities, in achieving accurate realignment of the quadriceps mechanism and in reducing postoperative complication rates.

Most surgeons agree that patients with lameness or hind limb deformity are candidates for surgical correction. However, there remain several areas of debate when considering patellar luxation management including, but not limited to, the following:

· Management of asymptomatic dogs

· Indications for advanced imaging

· Treatment of patellar luxation in juvenile dogs

· The ideal method of tibial tuberosity fixation

· The use of abrasion trochleoplasty and patellar groove replacement

· Threshold alignment values indicating a requirement for femoral or tibial osteotomy

· The need to alter surgical treatment in cats

In this session, the panel will discuss these controversial topics and detail the approaches that they take to ensure accurate measurement of conformational deformities and subsequent appropriate corrective surgery that is tailored to the individual.


* Participants are encouraged to send in questions to prior to the panel discussion. There will also be the opportunity to raise questions during the discussion.

    Sorrel graduated from the Royal Veterinary College (RVC), London. She then spent three years in private practice where she gained her Certificate in Small Animal Orthopaedics. She then returned to the RVC where she undertook a three-year residency in Small Animal Orthopaedics.

    She gained her RCVS diploma in Small Animal Orthopaedics in 1997 and then spent six months as a lecturer at the University of Pennsylvania before returning to take up a post as University Surgeon at Cambridge University Veterinary School. She gained her ECVS diploma in Small Animal Surgery in 1999 and became a European Specialist in Small Animal Surgery. She was appointed Chair in Small Animal Orthopaedic Surgery in 2013 at the University of Bristol.

    She is interested in all aspects of small animal orthopaedic surgery with particular interests in fracture repair, cruciate disease and hip replacement. She also has a particular interest in feline orthopaedics and she has published widely in this field and is frequently invited to lecture on feline orthopaedics both in this country and abroad. She has co-edited a textbook on Feline Orthopaedic Surgery and Musculoskeletal Disease and a partner textbook on Feline Soft Tissue & General Surgery.

    Sorrel is heavily involved in undergraduate and post graduate veterinary surgery teaching. Clinical research interests include feline patella fractures and feline cruciate disease.  In September 2019 Sorrel became a Fellow of the Royal College of Veterinary Surgeons for her outstanding contribution to the veterinary profession.

    Michael Kowaleski
    DVM, BS, Dipl.ACVS

    United States

    American Specialist in Veterinary Surgery
    More Info

    As a member of the Foster Hospital for Small Animals’ surgical team,Dr. Michael Kowaleski specializes in joint replacement, arthroscopy, stifle (knee) surgery, corrective osteotomy and fracture treatments. Although his most common patients are dogs and cats, he occasionally operates on exotic animals and, most recently, camelids such as alpacas. He serves as the course director for Principles of Surgery for second-year veterinary students and for an orthopedic elective in the third year, teaches small animal surgery for third-year students and serves as a facilitator for the school’s Problem Based Learning course for first year students.

    Dr. Kowaleski is a home-grown talent from a family of veterinarians. He grew up in nearby Sterling, Massachusetts and his father and sister are both veterinarians. He attended the Cummings School of Veterinary Medicine for his DVM studies and completed the dual residency in surgery at Tufts and Angell Animal Medical CenterThe practice of medicine has always intrigued me, Dr. Kowaleski says. I have always been adept at taking things apart and repairing them; thus surgery is a very good fit for me.

    Prior to joining the faculty at the Cummings School, Dr. Kowaleski was an assistant professor, then associate professor, of orthopedic surgery at The Ohio State University. He has enjoyed the demanding caseload here, as well as the opportunity to work on unique cases. Recently, he teamed up with the surgical team at the school’s Hospital for Large Animals to treat an alpaca with patellar luxation (looseness in the kneecap). In 2008, Dr. Kowaleski also adapted human instrumentation and implants to fix a middle-aged cocker spaniel with a poorly healing fracture in its elbow.

    Dr. Kowaleski also enjoys participating in the school’s clinical and basic science research projects (please see Dr.Kowaleski’s academic profile for the latest research publications) and travels nationally and internationally to present on the latest surgical techniques.

    Dr. Kowaleski and his wife, Lisa, have two young sons and enjoy boating, sailing, fishing, skiing and rock climbing.
