Arthroscopic rotator cuff repair (ARCR) is one of the most common surgical procedures performed in the shoulder. It is useful to predict post operative functional recovery period for accurate evaluation of surgical effect. However, there was little known about the postoperative functional recovery period after ARCR. The aim of this study was to evaluate functional recovery period post ARCR and elucidate preoperative affecting factors. We retrospectively evaluated 201 patients (126 male and 75 female), who had undergone ARCR. The average age at the surgery was 61.4 years old (33-83 years old). Patients were evaluated by using the Japanese Orthopaedic Association (JOA) shoulder scoring system. A well functioned shoulder was determined when the score was more than 25 points in pain, more than 8 points in function, more than 8 points in ADL and more than 25 points in ROM by JOA scoring system. A well recovery period was the required time to the well functioned shoulder conditon. The well recovery periods were divided into 3 groups: group A (63 cases) was less than 3 months, group B (81 cases) was between 3 and 6 months, group C (57 cases) was more than 6 months. We statistically evaluated relations among the following items: age, sex, stiffness, rotator cuff tear morphology and rotator cuff tear size in each group of the well recovery periods. There was a significant difference among age, stiffness, rotator cuff tear size and the well recovery periods. An early recovery was expected when they were young people, no stiffness and smaller size rotator cuff tear. There was no significant difference among sex, rotator cuff tear morphology and the well recovery periods. Age, stiffness and rotator cuff tear size are the main affecting factors for functional recovery periods.
