A rupture of the anterior cruciate ligament (ACL) leads to instability and disability in the knee. There is in the current situation different opinions about treatment methods for this injury. Whether the injury is dealt operative or conservative the physiotherapist has an important role in rehabilitation. Patients can choose where they want to get their care, which may lead to different experiences of the injury among physiotherapists. This can result in different perceptions of operative versus conservative treatment. The purpose of this study was to investigate the experiences and perception of conservative versus operative treatment of ACL rupture and whether they differed between physiotherapists at health centers and private/sports clinics. Method: A computer survey was sent out to 355 physiotherapists at health centers and private/sports clinics throughout Sweden. Results: Physiotherapists in private/sports clinics was found to have more experience of ACL rehabilitation than physiotherapists at health centers, p <.001, and they collaborated more frequently with orthopedic surgeons at this injury, p <0.001. The majority of physiotherapists (96%) felt that surgery is sometimes needed and that high levels of training are more often an indication of surgery than age and risk of secondary injury. The three most important factors for successful rehabilitation appeared to be motivated individual, personalized and progressive exercise program. Surgery was considered to be most necessary in contact sports, and the physiotherapists were generally positive to recommend athletes to return. Conclusion: The results indicate that the physiotherapist's view of operative versus conservative treatment is similar regardless of workplace or experiences of ACL rupture.
