Search for: [Abstract = "Rotator cuff \(RC\) injuries are the most common cause of pain and movement impairment of the shoulder. The aim of arthroscopic treatment is to achieve strong and durable junction between bone and tendon while allowing both structures to heal. Single row implantation technique is simpler, faster and requires less artificial material. Some believe that using fewer sutures with excellent results of repair is a great advantage of this technique. Double row technique is more challenging, however can produce RC junction similar to anatomical. Physiological movements of shoulder postoperatively are fully restored which was confirmed by biomechanical studies. Unfortunately double row technique requires more artificial material to build up junction and for some it is disadvantage of technique. It will also lead to increased cost of operation. The main aim of study was to compare arthroscopic treatment of shoulder with single or double technique and answer the following questions\: What was most common type of injury to RC treated with minimal invasive technique\? What were results of RC injury treatment when using two different techniques\? What was recovery time when using two different techniques\? Is age a risk factor for patients treated with two different techniques\? From 2005 to 2007 184 patients \(mean age 58±9.3, range 27\-79\) underwent arthroscopic reconstruction of injured RC. There was 99 male \(mean age, range\) and 85 females in the groups. Females were statistically significantly older. Patients were randomised to two groups. JR group\-single row technique DR group\-double row technique Results of surgery were assessed 3,6,12 months postoperatively. USG, Constatnt score, forward flexion range test, Job and Neer tests were used to evaluate results and recovery post surgery. Conclusions based on our results are\: Isolated, complete rupture of supraspinatus muscle tendon was the most common type of injury in both groups. Better results according to Constant test were observed in DR group. Better results were observed in patients with isolated injury to SNG than to SPG. There was twice less re\-injures confirmed by USG examination in DR group 12 months postoperatively. Better results 3 and 6 months postoperatively in DR group patients according to Constant score suggest less pain and wider range of arm’s movements. Similarly better range of arm flexion 12 months post surgery is suggesting faster recovery. Older patients \(>65 years old\) despite surgical technique used had worst results. Limited movements of arm and pain were still present 12 months postoperatively however improvement to preoperative status was still satisfactory according to Constant score."]
