Rotater cuff repair

PURPOSE: To determine the feasibility of shear wave elastography (SWE) with B-mode ultrasound in predicting the stiffness of the rotator cuff muscle before arthroscopic rotator cuff repair to evaluate the difficulty of the surgical procedure, as well as to compare SWE with the Goutallier stage on magnetic resonance imaging (MRI). METHODS: Thirty-eight patients with a full-thickness supraspinatus tear requiring arthroscopic rotator cuff repair participated. The Goutallier stage of fatty infiltration on MRI was measured before surgery, as was the SWE modulus of the anterior superficial, anterior deep, posterior superficial, and posterior deep (PD) regions of the supraspinatus muscle...

PURPOSE: This study aimed to evaluate the clinical outcomes and structural integrity of arthroscopic repair of intratendinous rotator cuff tear. METHODS: Patients who were diagnosed with an intratendinous tear but in whom conservative treatment failed were selected and underwent arthroscopic repair. Between 2008 and 2014, a total of 30 patients (6 men, 24 women; mean age, 59 ± 3.7 years) met the inclusion criteria and were followed up. The mean follow-up period was 26...

Purpose  The purpose of this study is to verify migration of mesenchymal stem cells of bursal tissue into the healing site after rotator cuff repair in rats. Methods  Fischer rats and green fluorescent protein (GFP)-transgenic rats were used. Bursal tissue from GFP rats was isolated and transplanted into tendon repair sites in Fischer rats. We examined the histology of the rotator cuff and the proportion of GFP-positive cells in the repaired rotator cuff 1, 3, and 6 weeks after surgery. Results  Cell migration was observed during the third and sixth week after surgery...

Study Design Clinical measurement. Background Recently, the Western Ontario Rotator Cuff Index (WORC) has been shortened; but few studies report measurement properties. Objective To compare the validity and responsiveness of disease-specific measures, short version of the Western Ontario Rotator Cuff Index (Short-WORC) and WORC with comparator measures (joint-specific: Shoulder Pain and Disability Index; SPADI, Simple Shoulder Test; SST); region-specific (Disabilities of the Arm, Shoulder and Hand; DASH); general health status (12-item short form health survey; SF-12v2)) in the patients undergoing rotator cuff repair (RCR)...

BACKGROUND: The comparison of clinical outcomes of arthroscopic footprint-preserving knotless single-row repair with the tear completion repair technique for articular-sided partial-thickness rotator cuff tears (PTRCTs) remains unclear. METHODS: A total of 68 patients diagnosed with articular-sided PTRCTs who underwent rotator cuff repair between December 2014 and June 2015 were included. Of the 68 patients, 30 received footprint-preserving knotless single-row repair (group 1) and 38 received the tear completion repair technique (group 2)...

PURPOSE: To evaluate the effects of rotator cuff muscle regeneration in sheep and establish an experimental model for the use of autologous stem cells as a treatment option for tendon injuries. METHODS: Infrared muscle tenotomies and Penrose drain implantation were performed on 12 shoulders of six clinically healthy adult sheep. After 60 days, the tendons were submitted to tissue repair, drainage removal, and divided into two groups according to the use of autologous stromal stem cells for treatment...

Since the introduction of reverse total shoulder arthroplasty (RTSA) in 1987 (in Europe) and 2004 (in the United States), the number of RTSAs performed annually has increased.Although the main indication for RTSA has been rotator cuff tears, indications have expanded to include several shoulder conditions, many of which involve dysfunction of the rotator cuff.RTSA complications have been reported to affect 19% to 68% of patients and include acromial fracture, haematoma, infection, instability, mechanical baseplate failure, neurological injury, periprosthetic fracture and scapular notching...

Purpose: Our aim was to identify predictors of construct selection and recent trends for arthroscopic knotless rotator cuff repair (RCR). Methods: A manual review of 1617 operative reports was performed. Results: A medium-sized tear had a threefold increase in odds of single row (SR) knotless repair (OR, 6.91; p = 0.009) versus SR knotted (OR, 3.05; p = 0.003). Generalist orthopaedic surgeons were 79% less likely to perform SR knotless repairs versus sports medicine trained specialists (p < 0...

Background: Radiological evaluation of rotator cuff tears are sensitive and specific. Accuracy may be low in diagnosing subscapularis tears. Materials and methods: We retrospectively reviewed shoulder arthroscopies performed by two surgeons over 45 months. We reviewed patients who had subscapularis repairs and their preoperative imaging. Result: 286 cases had imaging (193 MRIs, 93 USS) with 77 subscapularis repairs. MRI suggested 31 tears, arthroscopy confirmed 16 (30% sensitivity, 89% specificity)...

BACKGROUND: The authors have sometimes encountered postoperative new-onset pseudoparalysis (PONP) after arthroscopic repair for large to massive rotator cuff tear (ARCR). As there are insufficient data regarding PONP, the authors aimed to determine whether such a condition is characterized by obvious risk factors, as well as to assess the conditions under which it can be reversed. PURPOSE: To evaluate the predictors of PONP development after ARCR and its reversal and to integrate these predictors into a scoring system that can be applied in clinical practice...

Background: Limited literature exists regarding the influence of rotator cuff tear morphology on patient outcomes. Purpose: To determine the effect of rotator cuff tear pattern (crescent, U-shape, L-shape) on patient-reported outcomes after rotator cuff repair. Study Design: Cohort study; Level of evidence, 3. Methods: Patients undergoing arthroscopic repair of known full-thickness rotator cuff tears were observed prospectively at regular intervals from baseline to 1 year...

Biceps autograft can be a viable option for biological augmentation of massive rotator cuff repair, albeit results of this procedure might depend on the surgical technique. In the present qualitative systematic review, 8 case series were analyzed, in which biceps autograft was used as a scaffold or tissue bridge. Indeed, leaving the proximal portion intact and fixing it onto the greater tuberosity can simulate a superior capsule reconstruction, with potentially high biologic and mechanical advantages.

Distal mononeuropathy can be a pre-existing condition in patients undergoing arthroscopic rotator cuff repair. It can also develop after the surgical procedure.

"Breaking the fourth wall" is a theater convention where the narrator or character speaks directly to the audience. As an Assistant Editor-in-Chief, as I comment on a recent basic science study investigating rotator cuff repair, I break the fourth wall and articulate areas of basic science research excellence that align with the vision that we hold for our journal. Inclusion of a powerful video strengthens the submission. We prefer to publish clinical videos in our companion journal, Arthroscopy Techniques, and encourage basic science video submissions to Arthroscopy...

Understanding the type and rate of complications after shoulder rotator cuff repair could help surgeons to focus their quality improvement efforts. This is of great current relevance because value in health care is defined as the ratio of outcomes over cost, and complications increase cost significantly. A particular focus could be on lowering the rate of complications associated with "riskier" patients and "riskier" surgical techniques.

Propionibacterium acnes has long been known to play a detrimental role in shoulder surgery. This thoughtful and revealing study found significant evidence of lower rates of P. acnes cultured during arthroscopic rotator cuff repair with the use of an adhesive drape and chlorhexidine skin preparation.

Shoulder surgeons must carefully interpret literature that compares outcomes and complications of open and arthroscopic rotator cuff repair techniques. It is important for shoulder surgeons to be facile with both techniques.

Are we doing too many reverse total shoulder replacements and not fixing enough repairable rotator cuff tears? A convincing argument can be made for attempting to repair most, not all, very large rotator cuff tears in patients who do not have a significant arthritic change in the shoulder. My experience over more than 25 years of arthroscopic rotator cuff repair (ARCR) is that the only good way to know if it is repairable is to try. But some patients really do not pass my "eyeball test" as to whether they can rehabilitate and heal enough to make an ARCR reasonable...

BACKGROUND: Clinically, onto-surface repair is commonly used for rotator cuff tears. The retear rate after rotator cuff repair (RCR) is relatively high, with failure occurring mostly at the tendon-bone connection site. For anterior cruciate ligament (ACL) reconstruction, into-tunnel reconstruction is commonly employed. The retear rate after ACL reconstruction is relatively low, with retears seldom occurring at the tendon-bone interface. No study on into-tunnel RCR has been conducted. HYPOTHESIS: Into-tunnel RCR could promote fibrocartilage regeneration at the tendon-bone interface and has biomechanical advantage over onto-surface repair in a rabbit rotator cuff tear model...

OBJECTIVE: To evaluate whether augmentation grafts using autologous fascia lata improve functional results for rotator cuff repairs and reduce the retear rate compared to those without augmentation. MATERIAL AND METHODS: This is a prospective evaluation comprising 20 patients with a complete symptomatic rotator cuff tear. The operations were carried out from a superior approach performing a total cuff repair, for 10 patients we used a suture augmented with an autologous graft taken from their own fascia lata while unaugmented sutures were used for the other 10 patients...
