Clinical Outcomes After Reverse Total Shoulder Arthroplasty in Patients With Primary Glenohumeral Osteoarthritis Compared With Rotator Cuff Tear Arthropathy: Does Preoperative Diagnosis Make a Difference?

INTRODUCTION: The primary purpose of this study was to evaluate the clinical outcomes of patients who underwent reverse total shoulder arthroplasty performed for primary glenohumeral osteoarthritis (GHOA) with an intact rotator cuff compared with rotator cuff tear arthropathy (CTA). METHODS: This was a retrospective review of prospectively collected data including consecutive patients who underwent primary reverse total shoulder arthroplasty for GHOA or CTA with a minimum of 2-year follow-up. Baseline patient demographics and clinical outcomes including active range of motion, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numerical Evaluation, and visual analog scale for pain were collected. Univariate and multivariate regression analyses were performed to evaluate the effect of preoperative diagnosis on clinical outcomes. RESULTS: Patients with a preoperative diagnosis of GHOA demonstrated significantly better postoperative active forward elevation (138.6° versus 127.3°; P < 0.01), external rotation (54.2° versus 43.8°; P < 0.01), and change in internal rotation (Δ 2.1 points versus Δ 1.2 points; P < 0.01). Patients with GHOA demonstrated significantly better postoperative ASES (86.8 versus 76.6; P < 0.01), Single Assessment Numerical Evaluation (89.7 versus 78.5; P < 0.01), and visual analog scale scores (0.63 versus 1.2; P < 0.01). Minimal clinically important difference for ASES score was achieved by 97.5% of patients with GHOA compared with 86.7% of patients with CTA (P < 0.01), whereas substantial clinical benefit was achieved by 90.4% of patients with GHOA and 71.7% of patients with CTA (P < 0.01). After a multivariate linear regression analysis, postoperative ASES scores were independently associated with previous ipsilateral shoulder surgery (P = 0.042), preoperative ASES score (P = 0.01), and primary diagnosis of GHOA (P < 0.01). CONCLUSION: RTSA performed in patients with GHOA and an intact rotator cuff is associated with improved functional and clinical outcomes compared with those patients treated for CTA.

The Effect of State Legislation on Opioid Prescriptions Following Arthroscopic Rotator Cuff Repair.

New Jersey State Law, P.L. 2017 Chapter 28 22, C.24:21-15.2, passed in February 2017, is the most restrictive opioid legislation passed thus far in the United States. This study evaluated the effects of this legislation on the postoperative opioid prescriptions of patients undergoing arthroscopic rotator cuff repair (RCR). Opioid prescriptions were compared following arthroscopic RCR before and after implementation of the new law using the New Jersey Prescription Monitoring Program Aware Drug Database. A consecutive cohort of patients who underwent RCR during a 6-month period prior to the legislation was compared with a consecutive cohort of patients who underwent RCR during a 6-month period after the law went into effect. The primary outcome measure was prescribed postoperative milligram morphine equivalents (MME) and number of pills prescribed. There were 265 patients in the pre-law cohort and 198 patients in the post-law cohort. In the pre-law cohort, there was a median of 1250 MME (interquartile range [IQR], 900-1800 MME) and a median of 100 pills (IQR, 60-175 pills) prescribed postoperatively. In the post-law cohort, a median of 900 MME (IQR, 550-1050 MME) and a median of 60 pills (IQR, 60-90 pills) were prescribed postoperatively. A comparison of pre-law and post-law data for MME and number of pills prescribed was statistically significant (P<.001). The median opioid consumption MME and number of pills prescribed following RCR decreased significantly following the implementation of the New Jersey state law. Findings of this study indicate state regulations may play a role in reducing narcotic consumption following RCR. [Orthopedics. 2021;44(1):e80-e84.].

Content Relevance of the Foot and Ankle Ability Measure in Patients With Achilles Tendon Diseases.

BACKGROUND: The Foot and Ankle Ability Measure (FAAM) is among the most widely utilized and best psychometrically supported lower extremity-specific patient-reported outcome measures. However, its content relevance has never been directly subjected to patient assessment. METHODS: This was an institutional review board-approved, prospective, cross-sectional study of 75 patients with Achilles tendon diseases who ranked the relevance of the FAAM's items and subscales as 1 = Not relevant, 2 = Somewhat relevant, or 3 = Very relevant. Substantial content relevance was indicated by a minimum mean item or subscale score of 2.0. Nonsurgical and surgical subgroups were compared. RESULTS: At the whole group level, the mean score was above 2.0 for each individual item and subscale. Subgroup analysis revealed that the mean relevance was above 2.0 for each of the items and subscales with the exception of the "Personal Care" item, which nonsurgical patients ranked significantly lower than did surgical patients (mean = 1.74 vs 2.23, P = .02). Additionally, this was part of a general trend across items with more 95% confidence intervals crossing below 2.0 in the nonsurgical data set (15 items, 52%) than the surgical data set (1 item, 3%). CONCLUSION: These data confirm that the FAAM has substantial content relevance to patients with Achilles tendon diseases. However, it is unclear why the surgical subgroup consistently ranked items higher than did the nonsurgical subgroup. Future work should address how a patient's content relevance perception is influenced by the relative effects of their Achilles disease type and their perceived level of disease-related functional impairment.

Predicting Failure of Nonoperative Treatment for Insertional Achilles Tendinosis.

Nonoperative treatment for midportion Achilles tendinosis is well defined by the literature. Multiple modalities are described for the management of insertional Achilles pathology, but no consensus exists regarding efficacy. Surgical intervention for insertional Achilles tendinosis (IAT) is successful greater than 80% of the time. Our objective was to risk stratify patients who would fail nonsurgical management of IAT and thus benefit progressing to surgery. We reviewed the records of 664 patients with IAT. The cohort was 53% male and 80% obese. Mean age was 53.7 years (standard deviation 14.7 years). Average duration of symptoms was 10.4 months (standard deviation 28 months). Of the parameters collected, 4 were found to correlate with failing nonoperative treatment: visual analog scale, limited ankle range of motion, previous corticosteroid injection, and presence of Achilles tendon enthesophyte. We found that as the number of risk factors increased so did the chance of failing nonoperative treatment. With all 4 parameters, chance of failing conservative treatment was only 55%. Thus, nonoperative management should be exhausted until surgery is the only remaining option. However, the presence of one of the aforementioned risk factors can aid a surgeon in the decision to pursue surgery in the appropriate clinical scenario.
