From the reviews:

„The book of V. Sanchis-Alfonso is … welcome. … The chapters follow on the clinical examination, the differential diagnosis, the risk factors and the preserving treatment of the femoro-patellar syndrome extremely quite detailed with a very rich bibliography. … This excellent work is very complete, accessible to the non-specialist. It is a model which should be a work of specialized orthopaedists, essential to any surgeon being interested in pathology of the knee.“ (Patrice Diebold, European Journal of Orthopaedic Surgery and Traumatology, Vol. 19, 2009)
