Objective:To evaluate the surgical outcomes of recalcitrant medial epicondylitis combined with recalcitrant lateral epicondylitis or without.Methods:A retrospective study was conducted to analyze the clinical data of the 41 patients who had undergone suture repair of the flexor tendon via a small incision for recalcitrant medial epicondylitis between January 2010 and December 2023 at Department of Sports Medicine, Beijing Jishuitan Hospital, Capital Medical University. There were 13 males and 28 females, with an age of (52.4±7.6) years and duration of symptoms of 12 (6, 24) months. Of the patients, 26 suffered from simple recalcitrant medial epicondylitis (the simple group) and 15 recalcitrant medial epicondylitis combined with recalcitrant lateral epicondylitis (the combined group subjected to additional suture repair of the lateral tendon). The visual analogue scale (VAS) for pain, Mayo elbow performance score (MEPS), disabilities of the arm, shoulder, and hand (DASH) score, and grip strength level were evaluated at preoperation, postoperative 3 months, and the final follow-up to evaluate the surgical efficacy. Comparisons were made within the 2 groups.Results:The follow-up time for all patients was 12 (12, 16) months. At postoperative 3 months and the final follow-up, the VAS pain score [3.0 (1.8, 5.0) points, and 0.0 (0.0, 2.0) point], MPES [85.0 (81.3, 85.0) points, and 100.0 (85.0, 100.0) points], and DASH score [18.9 (12.7, 26.7) points, and 0.0 (0.0, 7.3) point] in the simple group were significantly improved compared with those at preoperation [5.0 (4.0, 7.0) points, 70.0 (65.0, 85.0) points, and 34.9 (23.2, 46.2) points] ( P<0.05). In the simple group, the grip strength at the final follow-up (88.4%±7.0%) was significantly improved compared with that at preoperation (50.2%±14.7%) ( P<0.05), but the difference in the grip strength was not statistically significant between that at postoperative 3 months (56.2%±12.3%) and that at preoperation ( P=0.137). In the combined group, at postoperative 3 months and the final follow-up, the VAS pain score [3.0 (3.0, 4.0) points, and 0.0 (0.0, 1.0) point], MPES [85.0 (85.0, 85.0) points, and 100.0 (85.0, 100.0) points], DASH score [16.7 (13.3, 23.3) points, and 3.3 (0.0, 7.0) points], and grip strength (58.9%±11.2%, and 86.9%±5.5%) were significantly improved compared with those at preoperation [5.0 (5.0, 7.0) points, 70.0 (60.0, 70.0) points, 45.6 (33.3, 46.6) points, and 43.7%±16.1%] ( P<0.05). Follow-ups revealed no complications requiring further treatment in all the patients. Conclusions:Early clinical follow-ups show that suture repair of the affected tendon through a small incision is an effective treatment of recalcitrant medial epicondylitis. Additional suture repair of the lateral tendon can also achieve good outcomes for those combined with recalcitrant lateral epicondylitis.

Objective:To explore the early curative effect of reverse shoulder arthroplasty in treatment of irreparable rotator cuff tear.Methods:Twenty-three patients with irreparable rotator cuff tears treated with reverse shoulder arthroplasty at Beijing Jishuitan Hospital from January 2020 to December 2022 were retrospectively analyzed, including 4 males and 19 females; age 69.3±8.6 years (range, 51-89 years), of which 8 patients were over 70 years and 15 patients were under 70 years; 5 patients were on the left side and 18 patients were on the right side; the duration of symptoms was 24 (4, 36) months; 7 patients with rotator cuff arthritis (CTA) and 16 with non-CTA. Functional scores including the American Shoulder and Elbow Surgeons (ASES), University of California Los Angeles (UCLA), simple shoulder test (SST), Constant - Murley scores, visual analogue scale (VAS) of pain, and range of motion including forward elevation, external rotation and internal rotation were collected to evaluate the postoperative efficacy of the treatment. ASES was considered as primary outcome, which was greater than 11.6 as for the minimal clinically important difference (MCID). The stratified analysis according to CTA or not and age greater than 70 years or not were performed to compare the efficacy of the two groups respectively.Results:Twenty-three patients were included with a follow-up time of 14.9±2.2 months (range, 12-19 months). The ASES, UCLA and Constant-Murley score improved from 46.6±14.8, 15.4±5.3 and 51.1±18.7 preoperatively to 87.3±4.5, 28.3±2.2 and 78.1±7.6 at the final follow-up, SST improved from 2(1, 4) preoperatively to 9(8, 10) at the final follow-up, VAS score decreased from 4(3, 5) preoperatively to 0(0, 1) at the final follow-up, and forward flexion supination improved from 77.1°±35.8° preoperatively to 125.2°±19.5° at follow-up; the difference between pre- and post-operative for all of the above metrics was statistically significant ( P<0.05). External rotation improved from 29.5°±22.2° preoperatively to 35.0°±13.5° at the final follow-up, and internal rotation improved from 5.0±3.0 points preoperatively to 5.3±2.8 points at the final follow-up, but none of the differences were statistically significant ( P>0.05). Minimal clinical important difference (100%) in postoperative improvement was achieved in all patients. CTA and non-CTA patients, although there was a significant difference between the two groups in preoperative ASES, Constant-Murley, SST, and VAS scores, the differences in each index were not statistically significant postoperatively ( P>0.05); the differences in all indexes between the two age groups, preoperatively and postoperatively, were not statistically significant ( P>0.05). Conclusion:Reverse total shoulder arthroplasty can achieve satisfactory clinical results in the early postoperative period in patients with irreparable rotator cuff tears. Although there are some preoperative functional differences, significant improvement can be achieved with reverse total shoulder arthroplasty regardless CTA or non-CTA patients. There was no significant difference in early postoperative outcomes between patients over 70 years and relatively younger patients.

Objective:To evaluate the outcome of arthroscopic surgical treatment for recalcitrant tennis elbow combined with degenerative lateral ulnar collateral ligament (LUCL) lesions.Methods:A retrospective case series study was made on clinical data of 27 patients with recalcitrant tennis elbow combined with degenerative LUCL lesions admitted to Beijing Jishuitan Hospital from June 2014 to December 2020. There were 19 males and 8 females, with the age range of 39-56 years [(49.8±6.9)years]. The degenerative LUCL lesions were evaluated arthroscopically. Arthroscopic LUCL debridement and shrinkage combined with repair of extensor carpi radialis brevis (ECRB) were performed in all patients. The operation time, intraoperative bleeding volume and length of hospital stay were recorded. The visual analogue scale (VAS), Mayo elbow performance score (MEPS), patient-rated tennis elbow evaluation (PRTEE) scale, and disability of the arm, shoulder and hand (DASH) questionnaire were evaluated and compared preoperatively and at the final follow-up.Results:All patients were followed up for 12-73 months [(24.1±9.7)months], with the operation time of 0.75-1 hours [(0.8±0.2)hours], intraoperative bleeding volume of 5-10 ml [(7.2±1.5)ml], and length of hospital stay of 4-12 days [(6.2±2.1)days]. The VAS, MEPS, PRTEE and DASH scores were significantly improved at postoperative 1 year [1(1,2)points, 95(85,100)points, 8(6,12)points and 12.9(8.9,15.8)points] when compared with those preoperatively [5(3,6)points, 70(65,85)points, 47(42,62)points and 43.8(36.8,49.0)points] (all P<0.01). No patients had limited range of motion, wound infection, heterotopic ossification, traumatic arthritis and other complications. Conclusion:For recalcitrant tennis elbow combined with degenerative LUCL lesions, arthroscopic LUCL debridement and shrinkage combined with ECRB repair can achieve pain relief and elbow function recovery.
