Project description:Arthroscopic rotator cuff repair is described as being a successful procedure. These results are often derived from clinical general shoulder examinations, which are then classified as 'excellent', 'good', 'fair' or 'poor'. However, the cut-off points for these classifications vary and sometimes modified scores are used.Arthroscopic rotator cuff repair is performed to improve quality of life. Therefore, disease specific health-related quality of life patient-administered questionnaires are needed. The WORC is a quality of life questionnaire designed for patients with disorders of the rotator cuff. The score is validated for rotator cuff disease, but not for rotator cuff repair specifically. The aim of this study is to investigate reliability, validity and responsiveness of WORC in patients undergoing arthroscopic rotator cuff repair.An approved translation of the WORC into Dutch is used. In this prospective study three groups of patients are used: 1. Arthroscopic rotator cuff repair; 2. Disorders of the rotator cuff without rupture; 3. Shoulder instability. The WORC, SF-36 and the Constant Score are obtained twice before therapy is started to measure reliability and validity. Responsiveness is tested by obtaining the same tests after therapy.
Project description:In this study, we collected rabbit supraspinatus muscle tissue with higher temporal resolution (1, 2, 4, 8 weeks)after 8 wk tear followed by repair (n=4/group), to determine time-depenet transcriptional changes after repair. RNA sequencing and analyses were performed using standard techniques to identify a transcriptional timeline of rotator cuff muscle changes and related morphological sequelae.
Project description:A histologically normal insertion site does not regenerate following rotator cuff tendon-to-bone repair, which is likely due to abnormal or insufficient gene expression and/or cell differentiation at the repair site. Techniques to manipulate the biologic events following tendon repair may improve healing. We used a sheep infraspinatus repair model to evaluate the effect of osteoinductive growth factors and BMP-12 on tendon-to-bone healing. Magnetic resonance imaging and histology showed increased formation of new bone and fibrocartilage at the healing tendon attachment site in the treated animals, and biomechanical testing showed improved load-to-failure. Other techniques with potential to augment repair site biology include use of platelets isolated from autologous blood to deliver growth factors to a tendon repair site. Modalities that improve local vascularity, such as pulsed ultrasound, have the potential to augment rotator cuff healing. Important information about the biology of tendon healing can also be gained from studies of substances that inhibit healing, such as nicotine and antiinflammatory medications. Future approaches may include the use of stem cells and transcription factors to induce formation of the native tendon-bone insertion site after rotator cuff repair surgery.
Project description:PurposeTo compare patient-reported and surgical outcome measures in patients with and without secondary shoulder stiffness (SSS) undergoing rotator cuff repair (RCR).MethodsPatients undergoing rotator cuff repair from 2014 to 2020 with complete patient-reported outcome measures (PROMs) by the short-form 12 survey (SF-12) were retrospectively reviewed to identify if operative intervention for SSS was performed alongside the RCR. Those patients with operative intervention for SSS were propensity matched to a group without prior intervention for stiffness by age, sex, laterality, body mass index, diabetes mellitus status, and the presence of a thyroid disorder. The groups were compared by rotator cuff tear (RCT) size, surgical outcomes, further surgical intervention, rotator cuff retear rate, postoperative range of motion (ROM), and SF-12 results at 1 year after surgery. Delta values were calculated for component scores of the SF-12 and ROM values by subtracting the preoperative result from the postoperative result.ResultsA total of 89 patients with SSS were compared to 156 patients in the control group at final analysis. The patients in the SSS group experienced a significant improvement in the delta mental health component score (MCS-12) of the SF-12 survey that was not seen in the control group (P = .005 to P = .539). Both groups experienced significant improvement by the delta physical health component score (PCS-12) of the SF-12 survey (SSS: 7.68; P < .001; control: 6.95; P < .001). The SSS group also experienced greater improvement of their forward flexion (25.8° vs 12.9°; P = .005) and external rotation (7.13° vs 1.65°; P = .031) ROM than the control group.ConclusionsOperative intervention of SSS at the time of RCR has equivalent postoperative SF-12 survey outcome scores when compared to patients undergoing RCR without preoperative stiffness despite those patients having lower preoperative scores.Level of evidenceLevel III retrospective comparative study.
Project description:Transosseous repair has been used safely and effectively for primary and revision rotator cuff repair for decades; as a result, it is considered by many the historical gold standard of open repair techniques. Transosseous repair offers the advantage of excellent biology, double-row anatomic footprint reconstruction, and the ability to create multiple low-cost fixation points per surface area of tendon with high-strength suture, while avoiding anchor pullout, cyst formation, and imaging artifact. More recently, in arthroscopic applications, transosseous-equivalent anchor-based repairs have been introduced that have shown satisfactory clinical and biomechanical results; however, these attributes have been coupled with increased cost, nonbiologic burden to the healing interface of the tendon, and new catastrophic failure modes including tendon transection, anchor pullout, and bone voids. This article delineates a technique for arthroscopic true transosseous hybrid cuff repair that combines the use of anchors and transosseous techniques to maximize the benefits and minimize the detriments of both techniques. Level 1 (shoulder); level 2 (rotator cuff).
Project description:Rotator cuff repair techniques continue to evolve in an effort to improve repair biomechanics, maximize the biologic environment for tendon healing, and ultimately improve patient outcomes. The arthroscopic transosseous-equivalent technique was developed to replicate the favorable tendon-bone contact area for healing seen in open transosseous tunnel repair. In this technical note and accompanying video, we present our all-arthroscopic transosseous-equivalent rotator cuff repair technique with a focus on technical pearls.
Project description:PurposeThe purpose of this study was to use a novel scoring system to evaluate the content and grade the quality of websites that patients may use to learn about rotator cuff repair.MethodsTwo search terms ("rotator cuff repair" and "rotator cuff surgery") were entered into 3 Internet search engines (Google, Yahoo, and Bing). We scored the quality of information using a novel scoring system. Website quality was further assessed by the Journal of the American Medical Association (JAMA) benchmark criteria and Health on the Net Foundation (HON) code certification. The readability of the websites was evaluated with the Flesch-Kincaid score.ResultsWe evaluated 47 websites. The average quality for all websites was 6.47 ± 5.21 (maximum 20 points). There was a large difference in scores between the top 5 websites and the remaining websites (16.30 vs 5.51, P < .001). There was no difference in scores when comparing the 3 different search engines (P = .85). The mean reading level was 10.17 ± 2.24. Reading level was not significantly correlated with quality (rs = 0.14, P = .36). The average JAMA benchmark criteria score for all websites was 2.34 ± 1.11 (maximum 4 points). JAMA criteria score was not significantly correlated with quality (rs = 0.02, P = .91). Sites without HONcode certification had higher quality scores (8.33 ± 4.80) than sites with HONcode certification (6.18 ± 4.66), but this difference was not statistically significant (P = .15).ConclusionThe quality of patient-level information on rotator cuff repair on the Internet is both incomplete and written at a reading level higher than current recommendations. Information quality is not significantly correlated with reading level or JAMA criteria, and does not depend on the search term used or HONcode certification.Clinical relevancePatients having rotator cuff repair may seek information on the Internet; the information may require surgeon clarification.
Project description:Massive rotator cuff tears are particularly challenging to treat and severely limit the function of the shoulder. Compared with a small rotator cuff tear, massive tears are more unpredictable and usually present with low tendon quality. When performing an anatomical repair of the rotator cuff, the surgical treatment is often associated with failure of the construct. An alternative procedure that can be performed in the setting of a massive tear is superior capsular reconstruction (SCR), using an autograft or allograft. This procedure has been shown to be effective and is associated with positive treatment outcomes. Moreover, the combination of an SCR with an anatomic repair of the rotator cuff tendon may provide a stronger fixation for the rotator cuff and ultimately lead to a lower likelihood of retear and failure. The purpose of this Technical Note is to describe our preferred procedure for the treatment of a massive rotator cuff tear through SCR with superimposition of the repair of the native rotator cuff tendons.
Project description:This Technical Note presents an arthroscopic technique to repair rotator cuff tears using a constant intra-articular (glenohumeral) portal for visualization. The smoothness of both the humeral head cartilage and the articular side of the rotator cuff offers a cleaner arthroscopic approach, while the absence of a subacromial bursa also reduces bleeding, turbidity, and the need for iterative soft tissue debridement. It also facilitates the recognition and repair of certain tear patterns. The intra-articular perspective allows the surgeon to visualize how stitches pierce the tissue in a desired and resistant area of the tendon. During knot tying, instead of watching the knot compressing against the bursal side of the tendon, the surgeon monitors how the articular side of the tendon is compressed and attached against the footprint while pushing the knot until the desired level of reduction is achieved.
Project description:Although open transosseous repair was historically used as a gold-standard surgical solution for rotator cuff tears, this procedure was largely replaced by anchor-based techniques because of the advancement of arthroscopic surgery. However, the ability of anchor-based repair to achieve similar biomechanical fixation remains uncertain. Despite the proposals of numerous methods over the last decade, there remains demand for a standard, reliable technique that integrates the biomechanical advantages of transosseous fixation within the realm of arthroscopy. We describe a technique for transosseous rotator cuff repair using the Omnicuff, a needle-based transosseous suture-passing device that minimizes the risk of failure of suture passage between the bone tunnels. With potential advantages of this design including automated-assisted suture passage, improved bone-tendon healing, and anchorless fixation, surgeons may be inclined to consider these biomechanical and cost-saving benefits. Future studies are warranted to determine clinical outcomes of this technique and its suitability for tears of varying degrees and patterns.
