Obesity is a global epidemic of 2.1 billion people and a well known cause of osteoarthritis. Joint replacement in the obese attracts more complications, poorer outcomes and higher revision rates. It is a reversible condition and the fundamental principles of dealing with reversible medical conditions prior to elective total joint replacement should apply to obesity. The dilemma for orthopaedic surgeons is when to offer surgery in the face of a reversible condition, which if treated may obviate joint replacement and reduce the risk and severity of obesity related disease in both the medical arena and the field of orthopaedics.

The August 2013 Foot & Ankle Roundup³⁶⁰ looks at: mobility, ankles and fractures; hindfoot nailing: not such a bad option after all?; little treatment benefit for blood injection in tendonitis; fixed bearing ankles successful in the short term; hindfoot motion following STAR ankle replacement; minimally invasive calcaneal fracture fixation?; pes planus in adolescents; and subluxing peroneals and groove deepening

The April 2013 Knee Roundup³⁶⁰ looks at: graft tension and outcome; chondrocytes at the midterm; pre-operative deformity and failure; the designer effect; whether chondroitin sulphate really does work; whether ACL reconstruction is really required; analgesia after TKR; and degenerative meniscus.
