Objective To review the progress in the treatment and research of massive rotator cuff tears. Methods Recent l iteratures about the treatment and research of massive rotator cuff tears were reviewed. Results Treatment options of massive rotator cuff tears include nonoperative treatment, debridement, direct repair, tendon transfer, and repair with various substitutes, but the outcome is unpredictable. Recently, many experimental studies on the treatment of massive rotator cuff tears, such as gene therapy, cell therapy, and tissue engineering techniques, can provide cl inicians with new treatment strategies. Conclusion The treatment of massive rotator cuff tears pose a distinct cl inical challenge for the orthopaedist, depending on the overall presentation. The effect of traditional operation method to repair massive rotator cuff tears is limited. The treatment and research of massive rotator cuff tears still need to be studied.
Objective To discuss and evaluate the diagnose and surgical techniques of rotator cuff tear with arthroscopic repair and its cl inical results. Methods From November 2006 to April 2008, 22 patients with rotator cuff tear were treated by arthroscopic repair using 5 different methods. There were 13 males and 9 females, aged 28-51 years old (mean37.9 years old). The locations were left shoulder in 6 cases and right shoulder in 16 cases. Eleven cases underwent shoulder joint injury and other 11 cases had no inducement. According to Bigl iani acromion classificatioin, there were 12 cases of type II and 10 cases of type III. There were 5 bursa-side tear, 3 articular-side tear, and 14 full thickness tear. The disease course was 5 months to 6 years (mean 16.6 months). After all the patients underwent acromioplasty, 4 cases were treated by debridement of rotator cuff, 7 cases by single roll suture anchor, 4 cases by double suture anchors, 3 cases by trible suture anchors, and 4 cases by transosseous technique suture. Results Incision healed by first intention and no compl ications occurred in all patients. Twenty-two cases were followed up 12-26 months (mean 15.6 months). The active forward flexion and abduction at the last follow-up were over 150° in 21 cases, 90-l20° in 1 case. Postoperatively, the forward flexion strength was grade 5 in 20 cases and grade 4 in 2 cases. The score of University of Cal ifornia Los Angeles, the pain score, the function score, the forward flexion score, the forward flexion strength were improved significantly when compared with preoperation (P lt; 0.05). The results were excellent in 13 cases and good in 9 cases, the excellent and good rate was 100%. Conclusion Depending on the correct diagnoses, 5 different methods of rotator cuff repair are used according to the different changes of shoulders, the outcome is good in all cases.

Methods From March 2010 to April 2011, there were 38 patients with shoulder pain were separately scanned by MRI at the position of oblique coronal, oblique sagittal and transaxial planes. Otherwise, the MRI images completed with T1 weighted, T2 weighted, PDWI and TIRM technique. The 38 cases were divided into two groups (group A: to study the supraspinatus and infraspinous tendons of the 38 cases; group B: to study the musculus teres minor and musculus subscapularis tendons of the 38 cases). Afterwards, the diagnostic results were compared among images at different patient positions. Furthermore, the images at oblique coronal plane of T1WI+T2WI and PWI+TIRM technique in group A were compared; on the other hands, the images at transaxial plane of T1WI+T2WI and PWI+TIRM technique in group B were compared. Results The difference of diagnostic accuracy in group A at different patient positions and scan sequences were statistical significant (Plt;0.05), and oblique cornal plane was the best patient position with sensitivity of 88.9%, specificity of 81.8% and accuracy of 86.8%; at the same time, the PWI+TIRM sequence was better sequence with sensitivity of 88.9%, specificity of 90.9% and accuracy of 89.5%. The difference of diagnostic accuracy in group B at different patient positions and scan sequences were statistical significant (Plt;0.05), and transaxial plane was the best patient position with sensitivity of 87.5%, specificity of 86.4% and accuracy of 86.8%; at the same time, the PWI+TIRM sequence was better sequence with sensitivity of 100%, specificity of 83.3% and accuracy of 94.7%. Conclusion In low field MRI, the oblique cornal plane with PWI+TIRM sequence are a first-line method for diagnosing supraspinatus tendon tears or infraspinous tendon tears; on the other hands, the transaxial plane with PWI+TIRM sequence are a first-line method for diagnosing musculus teres minor hurt or musculus subscapularis hurt.
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.
Objective To investigate effectiveness of rotator cuff repair with manipulation release and arthroscopic debridement for rotator cuff tear with shoulder stiffness. Methods A retrospectively study was performed on the data of 15 patients with rotator cuff tear combined with shoulder stiffness (stiff group) and 24 patients without stiffness (non-stiff group) between January 2014 and December 2015. The patients in the stiff group underwent arthroscopic rotator cuff repair with manipulation release and arthroscopic debridement while the patients in the non-stiff group only received arthroscopic rotator cuff repair. The patients in the stiff group were older than the patients in the non-stiff group, showing significant difference (P<0.05). There was no significant difference in gender, type of rotator cuff tear, side of rotator cuff tear, and combined with diabetes between 2 groups (P>0.05). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) were used to evaluate the effectiveness after operation. Results All incisions healed by first intention without any complication after operation. The patients were followed up 13-31 months in the stiff group (mean, 19.2 months) and 13-23 months in the non-stiff group (mean, 20.3 months). There was no significant difference in follow- up time between 2 groups (t=–0.573, P=0.570). The VAS score in the stiff group was higher than that in the non-stiff group before operation (t=–2.166, P=0.037); there was no significant difference between 2 groups at 3, 6, 12 months and last follow-up (P>0.05). The forward flexion and external rotation were significantly lower in the stiff group than those in the non-stiff group before operation and at 3 months after operation (P<0.05); there was no significant difference between 2 groups at 6, 12 months and last follow-up (P>0.05). At last follow-up, the internal rotation was beyond L3 level in 2 groups. The preoperative UCLA score was significant lower in the stiff group than that in the non-stiff group (P=0.037); but there was no significant difference in UCLA score at last follow-up between 2 groups (P=0.786). There was no significant difference in pre- and post-operative ASES scores between 2 groups (P>0.05). Conclusion Satisfactory effectiveness can be achieved in the patients with rotator cuff tear combined with shoulder stiffness after rotator cuff repair with manipulation release and arthroscopic debridement, although the patients with shoulder stiffness had slower postoperative recovery of ROM until 6 months after operation.
ObjectiveTo review the research progress of treatment for massive rotator cuff tears. MethodsThe domestic and foreign literature about the treatment of massive rotator cuff tears was reviewed. The methods and effectiveness were extensively summarized.ResultsThe treatment of massive rotator cuff tears still needs long-term research to promote its continuous improvement. The main goal of treatment is to relieve the symptoms and improve the shoulder joint function. With the development of arthroscopic technique, arthroscopic repair of rotator cuff tears has become a mature surgical protocol. Among these techniques, superior capsule reconstruction and patch augmentation for massive rotator cuff tears acquire more attention in recent years. As for rotator cuff arthropathy, reverse shoulder arthroplasty is considered to be a final choice. ConclusionSurgical treatment is the main choice for massive rotator cuff tears. Patients’ age and muscle condition should be taken into consideration to decide the surgical technique.
ObjectiveTo investigate the effect of unilateral rotator cuff repair on the contralateral shoulder in patients with bilateral rotator cuff tears.MethodsA clinical data of 46 patients with bilateral rotator cuff tears met the criteria between May 2016 and May 2019 was retrospectively analyzed. Of 46 patients, 23 patients underwent bilateral conservative treatment (conservation group), 23 patients underwent unilateral arthroscopic rotator cuff repair, and conservative treatment on the contralateral side (operation group). There was no significant difference in gender, age, disease duration, degree of rotator cuff tear, and comorbidities between 2 groups (P>0.05). Before operation and at 6 and 12 months after operation, the degree of the rotator cuff tear was measured by MRI, and the shoulder function was evaluated by the visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) (forward flexion, external rotation, external rotation at 90° of abduction, and internal rotation). The evaluation results of the non-surgical side of shoulders in the operation group were compared with one side of shoulders in the conservation group.ResultsAll incisions healed by first intention without any complication after operation. All patients were followed up 12 months. MRI reexamination showed that the degree of rotator cuff tear of the contralateral shoulder in the operation group increased significantly after operation (P<0.05). There was no significant difference between the operation group and the conservation group before operation (P>0.05), but the rotator cuff tear of the contralateral shoulder in the operation group was more serious than that of the conservation group at 6 and 12 months after operation (P<0.05). At 6 and 12 months after operation, the VAS score, UCLA score, and ASES score significantly improved when compared with the preoperative scores in 2 groups (P<0.05). There was no significant difference in the VAS score, UCLA score, and ASES score between 2 groups before operation (P>0.05). The function scores in the conservation group were better than those in the operation group at 6 and 12 months after operation (P<0.05). There were significant differences in the ROM of shoulder between pre- and post-operation in 2 groups (P<0.05). And there was no significant difference between 2 groups at pre- and post-operation (P>0.05).ConclusionFor patients with bilateral rotator cuff tears, the unilateral rotator cuff repair can aggravate the rotator cuff tear of contralateral shoulder.
ObjectiveTo evaluate the clinical effectiveness and safety of platelet-rich plasma (PRP) in the arthroscopic repair of full-thickness rotator cuff injury.MethodsRelevant randomized controlled trials were identified from Cochrane Library, PubMed, Embase, China Biology Medicine Database, Chongqing VIP Database, China National Knowledge Infrastructure, and Wanfang Database (from the dates of establishment to September 2020). A systematic review was performed to compare the short-term and mid-term retear rates, the scores of the University of California at Los Angeles (UCLA) Shoulder Rating Scale, and the scores of Visual Analogue Scale (VAS) between the two groups. Analyses were conducted using RevMan 5.2.0 software.ResultsNine studies with low heterogeneity were included in the meta-analysis involving 610 cases (305 in the PRP group and 305 in the control group). There were significant differences in the short-term retear rate [relative risk (RR)=0.29, 95% confidence interval (CI) (0.13, 0.65), P=0.003], the short-term and the mid-term UCLA scores [standardized mean difference (SMD)=0.35, 95%CI (0.14, 0.56), P=0.000 9; SMD=0.87, 95%CI (0.53, 1.21), P<0.000 01], the short-term and the mid-term VAS scores [SMD=−0.29, 95%CI (−0.51, −0.07), P=0.009; SMD=−0.35, 95%CI (−0.66, −0.03), P=0.03] between the two groups. There was no significant difference in the mid-term retear rate [RR=0.88, 95%CI (0.48, 1.63), P=0.69] or complication rate [RR=1.40, 95%CI (0.78, 2.54), P=0.26] between the two groups.ConclusionsPRP injection can effectively improve the clinical outcomes following arthroscopic repair of full-thickness rotator cuff tears, thus reducing the short-term retear rate, alleviating pain, and improving patients’ shoulder function.
ObjectiveTo investigate the effect of asymptomatic hyperuricemia on the effectiveness of arthroscopic rotator cuff repair.MethodsThe clinical data of 80 patients who underwent arthroscopic rotator cuff repair and met the selection criteria between March 2018 and December 2019 were retrospectively analyzed. According to the serum uric acid level, the patients were divided into hyperuric acid group (46 cases, the serum uric acid level was more than 417 μmol/L in males and was more than 357 μmol/L in females) and normal group (34 cases, serum uric acid level was lower than the above standard). There was no significant difference in gender, age, side, body mass index, blood glucose level, total cholesterol level, rotator cuff tear size, and preoperative shoulder motion, visual analogue scale (VAS) score, University of California-Los Angeles (UCLA) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and other general data between the two groups (P>0.05). The range of motion of abduction, forward flexion, and external rotation at 90° abduction were recorded and compared between the two groups before operation and at last follow-up; the improvement of shoulder pain was evaluated by VAS score; the improvement of shoulder function was evaluated by UCLA score, Constant score, and ASES score; and the shoulder joint MRI grade was evaluated according to Sugaya evaluation criteria.ResultsAll patients were followed up 9-16 months, with an average of 11.9 months; there was no significant difference in the follow-up time between the two groups (t=0.968, P=0.336). There were 2 cases of retear in the hyperuric acid group (including 1 case of severe tear) and 1 case of light retear in the normal group. The remaining patients in the two groups had no early-related complications. At last follow-up, the range of motion of the shoulder joints (abduction, forward flexion, external rotation at 90° abduction), VAS score, UCLA score, Constant score, and ASES score of the two groups were significantly improved when compared with preoperative ones (P<0.05); the above indicators in the normal group were significantly better than those in the hyperuric acid group (P<0.05). The MRI grade of the shoulder joint in the normal group was significantly better than that in the hyperuric acid group (Z=–2.000, P=0.045).ConclusionCompared with patients with normal serum uric acid level, asymptomatic hyperuricemia can lead to worse recovery after arthroscopic rotator cuff repair in patients with rotator cuff tears.
Objective To observe and evaluate the short-term effectiveness of superior capsular reconstruction using autologous fascia lata graft for irreparable massive rotator cuff tears. Methods The clinical data of 9 patients with irreparable massive rotator cuff tears treated with arthroscopic superior capsular reconstruction by using autologous fascia lata graft between September 2019 and April 2020 were retrospectively analysed. There were 4 males and 5 females with a median age of 66 years (range, 55-70 years). The disease duration was 6-60 months with an average of 19.1 months. According to Hamada classification, the patients were classified as grade 1 in 2 cases, grade 2 in 2 cases, grade 3 in 2 cases, and grade 4 in 3 cases. Before and after operation, the visual analogue scale (VAS) score was used to evaluate the improvement of shoulder joint pain, the American Shoulder and Elbow Surgeons (ASES) score, Constant score, and the University of California Los Angeles (UCLA) shoulder function score were used to evaluate the improvement of shoulder joint function. The active range of motion of shoulder joint was recorded, including forward flexion, abduction, lateral external rotation, and internal rotation. The changes of subacromial space were recorded by anteroposterior X-ray film of shoulder joint. Sugaya classification was used to judge the integrity of rotator cuff immediately after operation and at last follow-up. ResultsThe operation time was 210-380 minutes, with an average of 302.3 minutes. All incisions healed by first intention after operation, and there was no complication such as infection and nonunion of incisions. Two patients had numbness of the upper limbs on the surgical side after operation, and the numbness completely relieved at 6 weeks after operation; 5 cases with preoperative pseudoparalysis symptoms recovered after operation. Nine patients were followed up 12-17 months, with an average of 14.1 months. At last follow-up, the patient’s active range of motion of shoulder joint (forward flexion, abduction, lateral external rotation, and internal rotation), subacromial space distance, VAS score, ASES score, Constant score, and UCLA score significantly improved when compared with preoperative ones (P<0.05). There was no significant difference in the Sugaya classification between at last follow-up and immediately after operation (Z=−1.633, P=0.102). ConclusionSuperior capsular reconstruction using autologous fascia lata graft can restore the superior stability and achieve a good short-term effectiveness for irreparable massive rotator cuff tears.
