Arthroscopy 2024:S0749-8063(24)00485-7. [PMID: 38986853 DOI: 10.1016/j.arthro.2024.06.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 06/06/2024] [Accepted: 06/18/2024] [Indexed: 07/12/2024]
Abstract
PURPOSE To compare postoperative clinical outcomes at the 3-month, 6-month, 12-month, and latest follow-up in patients undergoing supervised physical therapy (PT) or a home-based exercise program after arthroscopic repair (ARCR) of massive rotator cuff tears (MRCTs). METHODS A retrospective review was conducted on a prospectively maintained database of patients who underwent either supervised PT or home-based therapy after ARCR of MRCTs between January 2015 and December 2018 at a single center with a minimum 24-month follow-up. At their 2-week postoperative routine follow-up, patients were allowed to choose between home-based and supervised PT. Patient-reported outcomes (PROs) and range of motion (ROM) were collected and compared between cohorts preoperatively and at the 3-month, 6-month, 12-month, and latest follow-up. The percentage of patients reaching or exceeding the minimal clinically important difference (MCID) and patient accepted symptomatic state (PASS) for visual analog scale for pain, American Shoulder and Elbow Surgeon (ASES) score, and Subjective Shoulder Value was recorded for both cohorts at each time point. Complications, healing, satisfaction, and return to work were reported. Healing was evaluated via ultrasound at the latest follow-up. RESULTS Ninety-nine patients met the study criteria: 61 in the supervised PT cohort and 38 in the home-based cohort. The supervised PT and home-based cohorts returned to the clinic for their most recent follow-up at 53 ± 20 and 55 ± 16 months (P = .496) after surgery, respectively. There was no difference when comparing tendon involvement (supraspinatus, P = .574; infraspinatus, P = .288; subscapularis, P = .592), tear retraction (P = .603), or high-grade fatty infiltration (supraspinatus, P = .684; infraspinatus, P = .397; subscapularis, P = .473) based on preoperative magnetic resonance imaging assessment and surgery-related factors, including anterior (P = .473) or posterior (P = .386) slides, fixation constructs (P = .829), or complete repair (P = .912). Both cohorts showed similar PROs and ROM at baseline. Postoperative PROs and ROM were similar among groups at the 3-month, 6-month, 12-month, and latest follow-up. However, ASES (71.4 vs 61.2; P = .013) and forward flexion (135° vs 118°; P = .023) were significantly higher at 3-month follow-up in the home-based cohort. Both groups comparably achieved MCID and PASS for PROs at the 3-month, 6-month, and 12-month follow-up. At the latest follow-up, the supervised PT and home-based cohort achieved MCID and PASS for visual analog scale (75% vs 81%, P = .573; 70% vs 72%, P = .911), ASES (76% vs 74%, P = .777; 72% vs 72%, P = .873), and Subjective Shoulder Value (82% vs 84%, P = .734; 72% vs 66%, P = .489), respectively. Satisfaction, healing, complication, and return-to-work rates were similar. CONCLUSIONS Patients undergoing rehabilitation using a home-based protocol showed largely similar functional scores and healing to those with supervised PT after ARCR of MRCTs at the latest follow-up. Although patients with home-based therapy achieved higher forward flexion and ASES at the 3-month follow-up, these became comparable starting at the 6-month postoperative mark. MCID and PASS were achieved similarly for PROs at each time point. LEVEL OF EVIDENCE Level III, retrospective case series comparison.

Abstract
BACKGROUND Previous research has emphasized the effect of prognostic factors on arthroscopic rotator cuff repair (ARCR) success, but a specific focus on subscapularis (SSC) tendon repair healing is lacking. PURPOSE To identify prognostic factors for SSC healing after ARCR and develop the Subscapularis Healing Index (SSC-HI) by incorporating these factors. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS This was a retrospective study using prospectively maintained data collected from patients with isolated or combined SSC tears who underwent ARCR between 2011 and 2021 at a single institution with a minimum 2-year follow-up. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and visual analog scale (VAS) pain scale. SSC tendon healing was evaluated via ultrasound at the final follow-up. Multivariate logistic regression analysis was performed to determine the factors affecting SSC healing, and based on these factors, the SSC-HI, which ranges from 0 to 15 points, was developed using odds ratios (ORs). RESULTS Among 1018 ARCR patients, 931 met the inclusion criteria; 279 returned voluntarily for postoperative SSC ultrasound assessment. The overall healing failure rate was 10.8% (30/279). Risk factors for healing failure included female sex (P = .008; OR, 3.119), body mass index (BMI) ≥30 (P = .053; OR, 2.323), supraspinatus fatty infiltration ≥3 (P = .033; OR, 3.211), lower SSC fatty infiltration ≥2 (P = .037; OR, 3.608), and Lafosse classification ≥3 (P = .007; OR, 3.224). A 15-point scoring system comprised the following: 3 points for female sex, 2 points for BMI ≥30, 3 points for supraspinatus fatty infiltration ≥3, 4 points for lower SSC fatty infiltration ≥2, and 3 points for Lafosse classification ≥3. Patients with ≤4 points had a 4% healing failure rate, while those with ≥9 points had a 55% rate of healing failure. Patients with a healed SSC reported significantly higher ASES (healed SSC: ΔASES, 44.7; unhealed SSC: ΔASES, 29; P < .01) and SSV (healed SSC: ΔSSV, 52.9; unhealed SSC: ΔSSV, 27.5; P < .01) and lower VAS (healed SSC: ΔVAS, -4.2; unhealed SSC: ΔVAS, -3; P < .01) scores compared with those with an unhealed SSC. CONCLUSION The SSC-HI scoring system integrates clinical and radiological factors to predict SSC healing after surgical repair. Successful SSC healing was found to be associated with enhanced functional outcomes, underscoring the clinical relevance of SSC healing prediction in the management of these tears.

Orthop J Sports Med 2024; 12:23259671241229429. [PMID: 38390399 PMCID: PMC10883133 DOI: 10.1177/23259671241229429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 12/06/2023] [Indexed: 02/24/2024] Open
Abstract
Background Few studies have reported clinical outcomes and tendon healing rates after arthroscopic isolated subscapularis (SSC) repair (AISR). Purpose/Hypothesis The primary purpose of this study was to evaluate clinical outcomes and tendon healing after AISR. It was hypothesized that AISR would result in satisfactory clinical outcomes along with a high rate of tendon healing at the midterm follow-up. The secondary purpose was to assess the influence of tear size and muscle atrophy on SSC tendon healing and patient-reported outcomes. It was hypothesized that both would be negatively correlated with healing but would have no effect on clinical outcomes . Study Design Case series; Level of evidence, 4. Methods A retrospective analysis was conducted on prospectively collected data for 77 patients who underwent primary AISR between 2011 and 2021 at a single institution, with a minimum 2-year postoperative follow-up for all patients. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, the Subjective Shoulder Value (SSV), and the visual analog scale for pain. Repair techniques and concomitant procedures were also collected. SSC tendon healing was evaluated via ultrasound at the final follow-up. Linear regression analysis was performed to determine factors affecting SSC healing. Results The mean follow-up was 58.1 ± 3.3 months. ASES scores significantly improved from 41.5 to 81.6, and the SSV improved from 38.2 to 80.5 (P < .01 for both). Among the 40 patients (51.9%) who underwent postoperative ultrasound, 87.5% showed complete tendon healing. There were no significant differences in outcome scores between healed and unhealed tendons. Increased muscle atrophy and larger tears were correlated with failure of SSC healing (β = -0.285 [P = .015] and β = -0.157 [P = .045], respectively). Conclusion Improved clinical outcomes and an overall high rate of tendon healing were seen at the midterm follow-up after AISR. Smaller tear sizes with less muscle atrophy were correlated with improved tendon healing. However, even when the tendon incompletely healed, the procedure improved functional outcomes.

Abstract
Purpose To assess functional outcomes and healing 4 years after arthroscopic repair of massive rotator cuff tears (MRCTs). Methods We conducted a retrospective study of patients who underwent arthroscopic rotator cuff repair of an MRCT-defined as a complete 2-tendon tear or a tear greater than 5 cm in any dimension-performed by 2 surgeons at different institutions between January 2015 and December 2018. At a minimum of 4 years postoperatively, patient-reported outcomes collected included the visual analog scale pain score, American Shoulder and Elbow Surgeons (ASES) score, Veterans RAND 12 (VR-12) score, and Subjective Shoulder Value (SSV) score. Repair technique and concomitant procedures were also gathered. Tendon healing was evaluated via ultrasound at final follow-up. Results Functional outcomes were available for 101 patients at a mean of 63.6 ± 8.8 months (range, 48-82 months) postoperatively. Mean ASES scores improved from 40.1 to 78 (P < .001); VR-12 scores, from 37.1 to 47.7 (P < .001); and SSV scores, from 36.7 to 84.6 (P < .001). Forward flexion improved from 126° to 144° (P = .001), external rotation remained unchanged (from 47° to 44°, P = .268), and internal rotation improved by 2 spinal levels (from L4 to L2, P = .0001). Eighty-eight percent of patients (89 of 101) were satisfied with the procedure, and only 5% underwent reverse shoulder arthroplasty within the study period. Among the 39 patients who underwent postoperative ultrasound to assess healing, 56% showed complete tendon healing. There was no difference in healing or outcomes according to tear pattern. Additionally, tendon healing did not affect outcomes. Conclusions Arthroscopic repair of MRCTs leads to functional improvements and patient satisfaction in most cases at 4-year follow-up. The rates of patients achieving the minimal clinically important difference were 77.5%, 87.6%, 59.7%, and 80.6% for the ASES score, SSV score, VR-12 score, and visual analog scale pain score, respectively. Complete tendon healing is difficult to achieve but does not appear to limit functional improvements. Level of Evidence Level IV, therapeutic case series.

Abstract
BACKGROUND. It is unclear which, MRI or ultrasound (US), is the most useful imaging tool to diagnose rotator cuff retears. OBJECTIVE. The objective of this study was to evaluate MRI and US in terms of diagnosing retear of a repaired rotator cuff tendon using a systematic review and meta-analysis. EVIDENCE ACQUISITION. A comprehensive literature search was performed on the main concepts of MRI (including noncontrast MRI and MR arthrography), US, and rotator cuff repairs. Inclusion criteria consisted of original research studies that assessed the diagnostic accuracy of MRI and US (index tests) for the diagnosis of rotator cuff tendon retear after prior rotator cuff repair using surgical findings as the reference standard. QUADAS-2 was used to assess methodologic quality. Meta-analyses were performed to compare MRI and US studies in the diagnosis of all retears and of full-thickness retears. Study variation was analyzed using the Cochran Q test and I2 statistic. EVIDENCE SYNTHESIS. Eight studies (MRI, n = 6; US, n = 2) satisfied inclusion and exclusion criteria, consisting of 304 total patients (MRI, n = 221; US, n = 83) and 309 shoulders (MRI, n = 226; US, n = 83). Years of publication ranged from 1993 to 2006 for the MRI studies and from 2003 to 2018 for the US studies. Two studies had high risk of bias in terms of applicability to clinical practice because of patient selection. Five studies had potential risk of bias in two categories, whereas two had potential risk of bias in three categories. For all retears, mean sensitivity and specificity for MRI were 81.4% (95% CI, 73.3-87.5%) and 82.6% (95% CI, 76.3-87.5%) and 83.7% (95% CI, 67.4-92.7%) and 90.7% (95% CI, 73.6-97.1%) for US. For full-thickness retears, mean sensitivity and specificity for MRI were 85.9% (95% CI, 80.2-90.2%) and 89.1% (95% CI, 84.6-92.4%) and 89.7% (95% CI, 75.6-96.1%) and 91.0% (95% CI, 75.5-97.1%) for US. There was no significant difference in terms of sensitivity or specificity for either comparison (p = .28-.76). CONCLUSION. Our analyses revealed no significant difference between US and MRI for the diagnosis of rotator cuff tendon tears after prior cuff repair. CLINICAL IMPACT. Either MRI or US can be considered a first-line imaging option to assess suspected rotator cuff retear after prior repair.

Abstract
AbstractRotator cuff pathology is a commonly encountered clinical and radiologic entity that can manifest as tendinopathy or tearing. Magnetic resonance imaging (MRI) and ultrasonography offer similar sensitivity and specificity for the evaluation of the native rotator cuff, and the chosen modality may vary, depending on local practice and accessibility. MR arthrography is frequently used in the postoperative setting as a problem-solving tool. Key findings to include in the preoperative MRI report include the size and location of the tear, thickness of the tendon involved (partial versus full thickness), and overall tendon quality. The report should also address features associated with poor surgical outcomes, such as fatty atrophy, a decreased acromiohumeral interval, and evidence of rotator cuff arthropathy. Musculoskeletal radiologists should be familiar with the various surgical techniques and expected postoperative imaging appearance of rotator cuff repairs. Imaging also plays a role in identifying recurrent tearing, graft failure, hardware loosening, infection, and other complications.

Abstract
BACKGROUND The relationship between the imaging parameters on postoperative ultrasound (US) other than repaired tendon integrity with clinical outcome such as postoperative residual pain has not been well defined. PURPOSE To investigate whether the repaired tendon thickness and subdeltoid fluid collection after rotator cuff repair are correlated with early postoperative clinical outcome. MATERIAL AND METHODS This retrospective study included 54 patients who underwent repair of the arthroscopic rotator cuff either by suture-bridge or single-row technique and postoperative US. We assessed the relationship between the sonographic parameters, including repaired supraspinatus tendon thickness and subdeltoid fluid collection, with the clinical outcome represented by the Korean Shoulder Scoring system (KSS) score using correlation coefficients (R). Also, the subgroup analysis was done to assess the differences by surgical technique and patients' age. RESULTS There was a significant inverse relationship between the amount of subdeltoid fluid collection and degree of self-assessed pain improvement of the patients (P < 0.05), although every KSS category showed statistically insignificant tendency of inverse relationship with the fluid thickness. However, there was no statistically significant relationship between the thickness of repaired supraspinatus tendon and KSS scores. In patients aged >60 years, a statistically significant inverse relationship between thickness of subdeltoid fluid collection and difference value of the KSS scores in category of function was observed with both interpreters (P = 0.015 and P = 0.04, respectively). CONCLUSION Subdeltoid fluid collection measured on US after repair of the arthroscopic rotator cuff in the early postoperative period has significant association with the patients' subjective clinical outcome.

Abstract
The aim of this article is to review the use of magnetic resonance imaging (MRI) for the evaluation of shoulder pain, which is a common clinical complaint of the musculoskeletal system. MRI is an essential auxiliary tool to evaluate these patients because of its high resolution and high sensitivity in depicting the soft tissues. This article will review the imaging technique, normal imaging anatomy, and most common imaging findings of disorders of tendons, labrum, and ligaments of the shoulder. It will also discuss common systemic diseases that manifest in the shoulder as well as disorders of the acromioclavicular joint and bursae. New advances and research in MRI have provided additional potential uses for evaluating shoulder derangements.
