ObjectiveTo investigate the effectiveness of reversed arthroscopic subacromial decompression in the treatment of rotator cuff tears. MethodsBetween November 2012 and January 2015, 53 patients with rotator cuff tears were treated with reversed arthroscopic subacromial decompression and rotator cuff repair. Of 53 patients, 38 were male and 15 were female, with the age of 47-61 years (mean, 53.4 years). The injury was caused by falling in 36 cases and other in 17 cases without an obvious history of trauma. All patients had shoulder pain and limited shoulder movement before operation. Visual analogue scale (VAS) was 6.4±0.9, and University of California at Los Angeles (UCLA) score was 16.3±1.9. MRI showed that distal supraspinatus tear was observed in 41 cases and distal infraspinatus tear in 12 cases; partial-thickness rotator cuff tear was observed in 9 cases and full-thickness tear in 44 cases. And the tear size was from 1 to 3 cm (mean, 1.9 cm). Combined injuries included tendinitis of long head of biceps brachii in 31 cases, Bankart lesion in 5 cases, and superior labrum anterior and posterior lesion in 2 cases. ResultsIncision healed by first intention in all patients; no infection or nerve injury occurred. Forty-nine cases were followed up from 12 to 35 months (mean, 22.8 months). After operation, shoulder pain relief was achieved in 42 cases; 7 cases had anterior shoulder pain at 3 months after operation, which was relieved after symptomatic treatment. At last follow-up, VAS score was significantly decreased to 0.5±0.6 (t=40.565, P=0.000). UCLA score was significantly increased to 33.8±1.7 (t=-79.799, P=0.000). The results were excellent in 42 cases, good in 6 cases, and fair in 1 case; the excellent and good rate was 98.0%. ConclusionReversed arthroscopic subacromial decompression can avoid coracoacromial arch injury and achieve good recovery of joint function, so it can be used in rotator cuff tears procedure.
ObjectiveTo investigate the effectiveness of Tang’s arthroscopy approach in treatment of anterior and posterior ankle impingement syndrome.MethodsBetween August 2010 and September 2017, 92 patients with anterior and posterior ankle impingement syndrome were retrospectively analyzed. There were 58 patients were treated with Tang’s arthroscopy approach under floating decubitus (group A) and 34 patients were treated with standard anterior and posterior approaches (group B). There was no significant difference in gender, age, body mass index, side, disease duration, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, and preoperative visual analogue scale (VAS) score between the two groups (P>0.05).The operation time, AOFAS score, VAS score, and Roles-Maudsley score were recorded to evaluated the pain and function of the ankle, and patient subjective satisfaction. The X-ray film and MRI at 12 months were used to observe the ankle impingement.ResultsMedian operation time of group A was 50.5 minutes ［95%CI (49.3, 54.6)］, which was significantly shorter than that of group B ［88.5 minutes, 95%CI (76.5, 92.8)］ (Z=−4.685, P=0.000). All incisions in group A healed by first intention; while the incisions of 2 cases in group B delayed healed after debridement. The follow-up time of group A was (54.7±18.8) months, while that of group B was (55.4±17.9) months, and there was no significant difference between the two groups (t=−0.178, P=0.859). The lateral X-ray films at 12 months showed that the talus process was removed incompletely in 2 cases (3.4%) of group A and 1 case (2.9%) of group B. There was no significant difference in the incidence between the two groups (χ2=0.014, P=0.699). At last follow-up, the AOFAS scores were 83.1±6.6 in group A and 85.2±6.4 in group B; the VAS scores were 1.3±1.1 in group A and 1.6±1.0 in group B. The AOFAS and VAS scores at last follow-up were superior to preoperative ones (P<0.05), but there was no significant difference between the two groups (P>0.05). The median subjective satisfaction score of group A was 2.0 ［95%(1.4, 1.7)］, which was better than that of group B ［2.0, 95%(1.6, 2.2)］ (Z=−2.480, P=0.013).ConclusionArthroscopic treatment of anterior and posterior ankle impingement syndrome through Tang’s approach can shorten the operation time, simplify the procedures, and obtain good effectiveness and patient satisfaction.
