Objective To investigate the effectiveness of “hybrid” suture with en masse combined with double-layer repair under arthroscopy in repair of delaminated rotator cuff tear by comparison with en masse suture. MethodsFifty-six patients with delaminated rotator cuff tears met selection criteria between June 2020 and January 2022 were included in the study. Patients were divided into two groups (n=28) using a random number method. The patients in trial group underwent arthroscopic “hybrid” suture with the combination en masse and double-layer suture. The patients in control group underwent en masse suture under arthroscopy. There was no significant difference between the two groups (P>0.05) in terms of gender, age, rotator cuff tear side, tear size, cause of injury, disease duration, and preoperative American Association of Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles (UCLA) shoulder scoring, visual analogue scale (VAS) score, and shoulder range of motion (forward flexion and lateral external rotation). The operation time, the difference of ASES score, UCLA score, VAS score, and shoulder range of motion (forward flexion and lateral external rotation) between pre- and post-operation were recorded and compared between the two groups (P>0.05). The rotator cuff healing was examined by MRI and evaluated based on the classification criteria of rotator cuff healing proposed by Sugaya et al. Results Three cases (1 case in the trial group and 2 cases in the control group) were excluded from the study due to loss of follow-up. Twenty-seven cases in the trial group and 26 cases in the control group were included in the final study analysis. All operations of the two groups were completed successfully. There was no significant difference in the operation time between groups (P>0.05). The follow-up time was 10-12 months (mean, 10.9 months) in the trial group and 10-13 months (mean, 11.4 months) in the control group. All incisions healed by first intention. No surgery-related complications occurred. The UCLA score, ASES score, VAS score, and shoulder range of motion (forward flexion and lateral external rotation) of both groups at 9 months after operation were significantly superior to those before operation (P<0.05). The difference of UCLA score, ASES score, and VAS score between before and after operation in the trial group were significantly better than those in the control group (P<0.05). There was no significant differences between the two groups in the difference of shoulder range of motion (forward flexion and lateral lateral rotation) (P>0.05). At 9 months after operation, according to the classification criteria of rotator cuff healing proposed by Sugaya et al, MRI showed that the rotator cuff healing of the trial group was significantly better than that of the control group (P<0.05). Conclusion Compared with en masse suture, arthroscopic “hybrid” suture for the repair of delaminated rotator cuff tear has advantages in relieving pain and improving shoulder joint function, and the rotator cuff healing is better.
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.
ObjectiveTo investigate early effectiveness of arthroscopic superior fulcrum reconstruction in the treatment of irreparable massive rotator cuff tear (IMRCT). Methods A retrospective analysis was conducted on the clinical data of 24 patients with IMRCT who met the inclusion criteria between January 2020 and April 2022. Among them, there were 11 males and 13 females with an average age of 56.2 years (range, 42-68 years). There were 12 cases of falling injuries, 3 cases of traction injuries, and the other 9 cases had no obvious causes. The disease duration ranged from 1 to 25 months (median, 6 months). The rotator cuff tears were classified as Hamada grade 2 in 18 cases and grade 3 in 6 cases, and Goutallier grade 1 in 3 cases, grade 2 in 20 cases, and grade 3 in 1 case. All patients were treated with arthroscopic superior fulcrum reconstruction. Visual analogue scale (VAS) score, Constant-Murley score, the University of California at Los Angeles (UCLA) score, and the American Shoulder and Elbow Surgeons (ASES) score were recorded before operation and at 1, 3, 6, and 12 months after operation. Results The operations were all successfully completed. The incisions healed by first intention and no related complications occurred. All patients were followed up 12-33 months (mean, 24.6 months). The VAS, Constant-Murley, UCLA, and ASES scores at different time points after operation were superior to those before operation (P<0.05). All of the above indicators further improved with time. Except for no significant difference in VAS and Constant-Murley scores between 6 and 12 months (P>0.05), the differences between the other time points were significant (P<0.05). At 12 months after operation, according to UCLA scoring standard, shoulder joint function was rated as excellent in 4 cases, good in 19 cases, and poor in 1 case, with an excellent and good rate of 96.0%. MRI showed that there was no graft re-tear and the transplanted tendon and bone tunnel healed. Conclusion The arthroscopic superior fulcrum reconstruction for IMRCT can effectively relieve the pain, improve the shoulder range of motion, and restore good shoulder function.
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.
Objective To investigate the effectiveness of arthroscopic long head of biceps tendon (LHBT) transposition combined with Swivelock anchor double fixation in treatment of massive and irreparable rotator cuff tears. Methods Between June 2019 and November 2021, 25 patients with massive and irreparable rotator cuff tears were treated by arthroscopic LHBT transposition combined with Swivelock anchor double fixation. There were 12 males and 13 females. The age ranged from 47 to 74 years (mean, 62.4 years). The disease duration ranged from 1 to 62 months (median, 7 months). The rotator cuff tears were classified as Hamada grade 2 in 25 cases and Goutallier grade 1 in 2 cases, grade 2 in 22 cases, and grade 3 in 1 case. Pre- and post-operative shoulder range of motion (ROM), visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, and Constant-Murley score were recorded. Postoperative complications were observed. The reconstructed tissue integrity was confirmed by MRI. Results All operations were successfully completed. The operation time was 120-330 minutes (mean, 189.6 minutes). All incisions healed by first intention. All patients were followed up 10-36 months (mean, 22.0 months). At last follow-up, the ROM in forward flexion, abduction, and external rotation, VAS score, UCLA score, and Constant-Murley score were superior to those before operation, and the differences were significant (P<0.05). According to UCLA scoring standard, shoulder joint function was rated as excellent in 5 cases, good in 18 cases, and poor in 2 cases, with an excellent and good rate of 92.0%. No other complications occurred except shoulder joint adhesion in 2 cases. At last follow-up, MRI examination showed no retear of rotator cuff, and LHBT was intact. Conclusion For massive and irreparable rotator cuff tears, arthroscopic LHBT transposition combined with Swivelock anchor double fixation can increase the force of pressing the humeral head, effectively relieve the pain, improve the ROM of joints, maximize the recovery of shoulder function, and do not increase the number of anchor nails.
Objective To review the research progress of arthroscopic long head of biceps tendon (LHBT) transposition in treatment of irreparable massive rotator cuff tears. Methods The domestic and foreign related literature in recent years on the treatment of irreparable massive rotator cuff tears with different LHBT transposition methods under arthroscopy was reviewed and analyzed. Results Arthroscopic LHBT transposition is an effective method for irreparable massive rotator cuff tears, which mainly includes “proximal cut”, “both two cuts”, “distal cut”, and “no cut”. Different methods of LHBT transposition can achieve good effectiveness, but its long-term effectiveness needs further follow-up. Conclusion Arthroscopic LHBT transposition in treatment of irreparable massive rotator cuff tears is simple and effective. The patients can recover quickly after operation with less injury. But the technique has higher requirements for surgeons, and the indications must be strictly controlled.
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 effectiveness of arthroscopic superior capsular reconstruction using a “sandwich” patch combined with platelet-rich plasma (PRP) injection in treating massive irreparable rotator cuff tears. Methods A clinical data of 15 patients (15 sides) with massive irreparable rotator cuff tears, who were admitted between September 2020 and March 2023 and met the selective criteria, was retrospectively analyzed. There were 8 males and 7 females with an average age of 62.1 years (range, 40-80 years). The rotator cuff tears were caused by trauma in 7 cases and other reasons in 8 cases. The disease duration ranged from 5 to 25 months, with an average of 17.7 months. According to the Hamada grading, the rotator cuff tears were rated as grade 1 in 2 cases, grade 2 in 8 cases, and grade 3 in 5 cases. All patients were underwent superior capsular reconstruction using the “sandwich” patches (autologous fascia lata+polypropylene patch+autologous fascia lata) combined with PRP injection on patches. The pre- and post-operative active range of motion (ROM) of the shoulder joint, American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, University of California, Los Angeles Shoulder Rating Scale (UCLA) score, and visual analogue scale (VAS) score were recorded. The subacromial space was measured on the imaging and rotator cuff integrity was assessed based on Sugaya grading. Results All incisions healed by first intention after operation without any complications such as infection. All patients were followed up 12-18 months (mean, 14.4 months). At last follow-up, the active ROMs of flexion, abduction, external rotation, internal rotation of the shoulder joint, subacromial space, ASES score, Constant-Murley score, and UCLA score increased, and VAS score decreased, showing significant differences when compared with preoperative values (P<0.05). There was no significant difference in the Sugaya grading between last follow-up and immediately after operation (P>0.05). Conclusion For massive irreparable rotator cuff tears, arthroscopic superior capsular reconstruction using the “sandwich” patches combined with PRP injection can restore stability of the shoulder joint, relieve pain, promote rotator cuff healing, and achieve good short-term effectiveness.

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.
