This excellently illustrated book adopts an evidence-based approach to evaluate the efficacy of different techniques for the imaging and treatment of patellofemoral pain, instability, and arthritis. The aim is to equip practitioners with an informative guide that will help them to manage disorders of the patellofemoral joint by casting light on the many issues on which a consensus has been lacking. The opening chapters supply essential background information and explain the role of various imaging modalities, including radiography, CT, MRI, and bone scan. The various conservative and surgical treatment approaches for each of the three presentations - pain, instability, and arthritis - are then described and assessed in depth, with precise guidance on indications and technique. Postoperative management and options in the event of failed surgery are also evaluated. Throughout, careful attention is paid to the literature in an attempt to establish the level of evidence for each imaging and treatment method. The new edition has been thoroughly updated, with inclusion of additional chapters, in order to present the latest knowledge on biomechanics, diagnosis, surgical techniques, and rehabilitation.
