How to manage patellofemoral pain - Understanding the multifactorial nature and treatment options.

Phys Ther Sport 2018 Jul 12;32:155-166. Epub 2018 Apr 12.

Sports and Exercise Medicine, William Harvey Research Institute, School of Medicine and Dentistry, Queen Mary University London, London, United Kingdom; Sport and Exercise Medicine Research Centre, School of Allied Health, La Trobe University, Melbourne, Australia.

Patellofemoral pain (PFP) is one of the most prevalent conditions within sports medicine, orthopaedic and general practice settings. Long-term treatment outcomes are poor, with estimates that more than 50% of people with the condition will report symptoms beyond 5 years following diagnosis. Additionally, emerging evidence indicates that PFP may be on a continuum with patellofemoral osteoarthritis. Read More

Patellofemoral arthroplasty: Current concepts.

J Clin Orthop Trauma 2018 Jan-Mar;9(1):24-28. Epub 2017 Nov 22.

Department of Trauma & Orthopaedic Surgery, Lewisham & Greenwich NHS Trust, Queen Elizabeth Hospital, London, SE18 4QH, United Kingdom.

Isolated patellofemoral arthritis (IPA) is a debilitating condition characterised by a loss of articular cartilage on the patella facets, the trochlear groove or both. By definition, patients with IPA must have normal cartilage in the tibiofemoral compartments of their knee. It is therefore logical to pursue arthroplasty which corrects the abnormality while sparing healthy bone and preserving the knee's native kinematics, which is the premise underpinning patellofemoral arthroplasty (PFA).
