Musculoskeletal impairments affect one-third of the adult population, are one of the major contributors to lost time from work, and account for one-third of a general practitioner's caseload. These injuries respond well to physiotherapy, but access can be limited in a publicly funded health care system. Improved access to physiotherapy occurs in a collaborative model of care in orthopedic clinics however the extent to which the patient receives similar diagnoses and treatment recommendations has not been reported. The purpose of this study was to determine diagnostic concordance and accuracy, and treatment concordance between a physiotherapist and orthopedic surgeons. Twenty-five subjects in an orthopedic clinic were assessed by a physiotherapist and an orthopedic surgeon. Diagnosis and treatment recommendations were made by each separately. These were compared for concordance between professionals and diagnostic accuracy. The physiotherapist and the orthopedic surgeon had 90% concordance in diagnoses of knee and shoulder impairments, and 75% accuracy when compared to definitive diagnostic methods. They had 87% agreement in treatment recommendations, however, the physiotherapist gave three treatment recommendations per patient where the surgeon gave two. In a collaborative care context therefore, this study suggests, that physiotherapists have similar diagnostic capabilities to orthopedic surgeons, and they will enhance the conservative treatment options offered to orthopedic patients.
