We report about CRPS type 1 after arthroscopic rotator cuff repair. From June 2004 to June 2010, 209 patients underwent arthroscopic rotator cuff repair in our hospital. We studied about the rate of CRPS type 1 and the term from operation to the appearance of symptoms. We also checked the relationship between the phase of exercise of range of motion and the moment of onset of CRPS type 1. Moreover, we changed the policy of physical examination in painful cases to a slow plan of rehabilitation and relaxation program. We examined the difference of rate of CRPS type 1 between the two groups of before the change, and after it. The rate of CRPS type 1 is 11.0% (23 cases of 209 cases). 52.2% (13/23 cases) of CRPS type 1 showed the onset of symptoms up to 1 week after the change of the phase of exercise. We decreased the rate of CRPS type 1 after the change of policy in rehabilitation from 10.1 % to 4.9 %. We suppose that an increase of load in exercise causes CRPS type 1. We may prevent it by using a slow plan of rehabilitation and relaxation program.
