A Mason-Allen technique is feasible with open/mini-open cuff repair. Pierre et al. have developed an arthroscopic cruciate suture technique with a suture anchor, which is similar to the modified Mason-Allen technique. Their biomechanical study has demonstrated that the cruciate technique with a suture anchor has a higher load to failure than the modified Mason-Allen technique. With combination of the suture anchor and transosseous suture technique, we have developed a new method the Open Cruciate Suture (OCS) repair technique. In this study, the functional and structural outcome of the OCS technique was compared with those of open transosseous simple suture (OTSS) technique as conventional fixation method. From April 2005 to June 2007, 62 patients underwent open cuff repair: 32 with OCS and 30 with OTSS repair techniques. ROM, muscle strength, VAS, and JOA score were examined pre- and post-operatively. Postoperative cuff integrity was evaluated at postoperative 1 year, by MRI using Sugaya`s classification. Of 62 patients, 47 patients with more than 1 year follow-up were candidates for this study: 25 with OCS repair and 22 with OTSS repair. As well as the preoperative patient's profile, there was no significance between the 2 groups in postoperative functional outcome including ROM, muscle strength, VAS, and JOA scores. Postoperative MRI revealed. significantly less re-tear rate in OCS repair (8.3% vs 37.5%). Both techniques were comparable in terms of functional outcome, although the OCS repair technique produced superior structural outcome with significantly less re-tear rate.
