A rotator cuff tear is one of the most common traumatic and degenerative tendon injuries resulting in over 4.5 million physician visits in the US alone. Functional restoration of
Surgical repair of rotator cuff tears have high failure rates (20–70%), often due to a lack of biological healing. Augmenting repairs with extracellular matrix-based scaffolds is a common option for surgeons, although to date, no commercially available product has proven to be effective. In this study, a novel collagen scaffold was assessed for its efficacy in augmenting rotator cuff repair. The collagen scaffold was assessed in vitro for cytocompatability and retention of tenocyte phenotype using alamarBLUE assays, confocal imaging and real-time PCR. Immunogenicity was assessed in vitro by the activation of pre-macrophage cells. In vivo, using a modified rat
Introduction and Aims: Large or recurrent rotator cuff tendon tears are difficult to treat effectively. Collagen bio-scaffolds have become available to reinforce a tendon repair or as an interpositional graft. This study compares the suitability of two collagen bio-scaffolds for autologous tenocyte implantation, and assesses the in vivo rotator cuff healing response with these grafts in a rabbit model. Method: Tenocytes were isolated from rabbit tendon, cultured and seeded onto the Restore patch (DePuy), or the Matricel (Verigen) collagen membrane. Serial scanning electron microscopy examined tenocyte integration with the bio-scaffold, and extra-cellular matrix synthesis over time. A
Large and retracted rotator cuff tendon tears fail to repair, or re-tear following surgical intervention. This study attempted to develop novel tissue engineering approaches using tenocytes-seeded bioscaffolds for tendon reconstruction of massive
Purpose: With this retrospective study, the results of rotator cuff repairs in patients of 60 years and older were compared to patients younger 60. Methods: 76 patients with an average age of 65 years (60–78 years, group A) and 167 patients younger 60 years (group B) were clinical (Constant – score) and sonographical examined after follow-up of 2 years after reconstruction of the rotator cuff. Results: In group A, 24 one-, 37 two-, 11 three- and 4 four-tendon tears were treated and the average age and gender adjusted Constant-score was 90,4% (13–126%). 29% showed sonographical signs of a re-defect. In group B, 56 one-, 69 two-, 33 three-, and 9 four-tendon tears were treated and the average age and gender adjusted Constant-score was 81,1% (15–116%). 32% showed sonographical signs of a re-defect. Conclusion: Both groups did not show significant differences regarding clinical results in the Constant-score size of the
Various surgical treatment were reported on rheumatoid shoulder. However, there were no recommended surgeries in the Japanese 2. nd. basic published text of rheumatoid disease. We had performed total shoulder arthroplasty(TSA) and humeral head replacement (HHR) in patient with Rheumatoid shoulder from 1992. The aim of this study was to compare the outcome of humeral head replacement, 2. nd. generation TSA and 3. rd. generation TSA in patients followed more than 5 years with rheumatoid shoulder. Material & Method. From 1992–2007, we performed shoulder arthroplasty in 42 shoulders in 40 patients. Six cases were not able to follow due to die and lost. All 36 shoulders in 34 patients could be followed with x-ray examinations more than 5 years. Averaged follow-up period was 8.6 years (range 5–14.5). HHR with intact cuff performed in 10 shoulders, 2. nd. generation TSA with intact cuff in 10, 3. rd. generation TSA in intact cuff in 10 and HHR with muscle tendon transfer in 6 shoulders. The shoulder score of Japanese Orthopaedic Association)JOA score. Modified Neer classification, ROM, lucent lines in X-ray and complications were investigated. Results. In JOA score, 3. rd. generation TSA revealed highest score (84 points). Also, in Modified Neer classification, excellent results were obtained 50% of cases in 3. rd. generation TSA. On the other hand, HHR with muscle tendon transfer group has no cases of excellent results. In flexion & external rotation, 3. rd. generation TSA had achieved satisfactory results. In X-ray, all glenoid component had a lucent line around the keel type glenoid in 2. nd. generation TSA. However, only 1.6 points in Lazarus claasification revealed in peg type component in 3. rd. generation TSA. No nerve injuries and instability were found after surgery. However, two infections and two glenoid resurfacing need after surgery. Discussion. In this mid-term results, 3. rd. generation type of TSA system could get favorable results in RA shoulders with intact cuff. However, the treatment for rheumatoid shoulder cases which has masssive
Introduction: New biotechnologies create opportunities for gene therapy to promote rotator cuff healing. We have previously demonstrated that genetically engineered mesenchymal stem cells (MSCs) over expressing BMP-2 and SMAD8 signaling molecule differentiate to tenocytes in vitro and in vivo. Therefore, we hypothesized that
Shoulder rotator cuff tears can be very debilitating and painful. Whilst massive tears may defy attempts at surgical repair due to the size of the defect, various biological materials have been proposed to reinforce tenuous repairs; initial results have been promising. It has been suggested that these materials may be used to bridge defects in the rotator cuff as a ‘patch’ or ‘interposition implant’ to provide pain relief and even offer some hope of functional recovery. A porcine dermal collagen implant (Permacol ©) has been engineered and introduced for the repair and reconstruction of soft tissues in the human body. In orthopaedics, it has been successfully used in the reinforcement and augmentation of rotator cuff repairs by suturing it over the repaired tendon. Proper et al reported good short term results in using this implant to bridge defects in massive rotator cuff tears and suggested it was good solution for this group of patients, reporting improvement in all aspects of the Constant Score. We have used Permacol © to reinforce cuff repairs with satisfactory results and thus considered its use as a salvage procedure to bridge massive
Background: The purpose of this study was to evaluate the mid and long-term results of the open repair of the rotator cuff tears in patients where pain of the shoulder was the primary and function the secondary consideration. Material – Method: the study includes 48 patients, out of a total 64, operated on during the period 1985–2001 for full-thickness massive tears of the rotator cuff. The average age was fifty-two years. In all but six the main symptom was persistent pain resulting from a chronic tear. This group had clinical evidence of a
Aim: To evaluate the role and outcome of FFTSA in shoulders with arthritis and/or irreparable rotator cuff tears. Materials. The records of 60 consecutive patients with FFTSA were retrospectively reviewed. Primary FFTSA (group 1) was performed in 29 (48%), revision FFTSA (group 2) in 26 (43%), and re-revision FFTSA (group 3) in 5 (9%) patients. The mean age at primary FFTSA was 70 years (37 – 82), and at revision FFTSA, 67.6 years (38 – 89) at a mean interval of 38 months after primary intervention. In re-revision FFTSA the interval between the primary (mean age 64 years) and final (mean age 68.4 years) interventions varied from 20 to 148 months. Primary FFTSA was performed for cuff arthropathy in 18 (62%) and after trauma in 5 (17%): all 29 patients had rotator cuff insufficiency. Revision FFTSA was performed for failure of humeral head replacement (HHR) after fracture in 17 (65%) of which 14 had rotator cuff insufficiency. All those in group 3 had rotator cuff insufficiency. The dominant indication for intervention was pain in 59 cases. The glenoid component was uncemented in all cases. The humeral component was cemented in 27 of the 29 Primary FFTSA. CADCAM variations of the standard humeral design were used in 8 cases. Results. At a mean follow-up of 25 months, 81% of primary FFTSA had no or mild pain, and 87.5% were satisfied or very satisfied with the outcome: both outcomes were independent of the original

Introduction. Definition-in this presentation, the discussion will not include reparable cuff deficiency, as this is handled with standard arthroplasty techniques combined with cuff repair. Factors that affect decision-making. Kinematics-fixed fulcrum or not. Bone loss. Deltoid integrity. Coracoacromial arch integrity. Age. Activity level. Options. Hemiarthroplasty. “ Extended head” hemiarthroplasty. Arthroplasty + tendon transfer. Constrained arthroplasty – currently not FDA approved in USA. Arthrodesis. Evaluation. History and physical examination. ? Prior surgery. ? Overhead function – does fixed-fulcrum kinematics exist even if the head is not centred. ? Anterosuperior instability – lack of fixedfulcrum kinematics. Cuff strength. Deltoid integrity. Radiographs – bone loss, especially glenoid. Other imaging studies not necessary. Arthroplasty. Hemiarthroplasty. Best if fixed fulcrum kinematics exists – intact CA arch, intact deltoid, at or above shoulder elevation. Technical considerations. Preserve deltoid. Preserve coracoacromial ligament, acromion. ? Preserve remaining subscapularis – make humeral cut superiorly, through the
We report a long term experience on massive rotator cuff tears treated by the means of a nonresorbable transosseously fixed patch combined with a subacromial decompression. From December 1996 until August 2002, a total of 41 patients were treated with a synthetic interposition graft and subacromial decompression. All patients had a preoperative ultrasound evidence of a primary massive full-thickness tear that was thought to be irreparable by simple suture. All patients were evaluated pre- and postoperatively using the Constant and Murley score, DASH questionnaire, Simple Shoulder Test, VAS scale for pain, ultrasound and plain radiographs. The patients consisted of 23 men and 18 women aged 51–80 years (mean 67 years). We had a lost of follow up of 6 patients. One patient had a total shoulder arthroplasty at 7.7 years and one patient had a redo with a new synthetic graft at 9.6 years. They were followed up for a mean of 7.2 years. Their mean preoperative Constant and Murley score improved from 25.7 preoperatively to 69.6. Similar improvements were seen with the DASH score (56.6 to 23.3), SST (1.2 to 7.9) and VAS scale (75.4 to 14.1). Anatomically, the repair resulted in mean acromio-humeral interval of 6.6 mm. Ultrasound showed a further degeneration of the rotator cuff with tears posteriorly from the interposition graft. In 67.7% of all patients the graft was continuous present. Histology – obtained from one patient scheduled for a reversed shoulder arthroplasty- showed partial ingrowth of peri-tendinous tissue. Despite ongoing degeneration of the cuff in nearly half our population, restoring a massive
