Managing rotator cuff tear arthropathy: a role for cuff tear arthropathy hemiarthroplasty as well as reverse total shoulder arthroplasty.

BACKGROUND: Disabling cuff tear arthropathy (CTA) is commonly managed with reverse shoulder arthroplasty (RSA). However, for patients with CTA having preserved active elevation, cuff tear arthropathy hemiarthroplasty (CTAH) may offer a cost-effective alternative that avoids the complications unique to RSA. We sought to determine the characteristics and outcomes of a series of patients with CTA managed with these procedures. MATERIALS AND METHODS: We retrospectively reviewed 103 patients with CTA treated with shoulder arthroplasty, the type of which was determined by the patient's ability to actively elevate the arm. Outcome measures included the change in the Simple Shoulder Test (SST), the percent maximum improvement in SST (%MPI), and the percentage of patients exceeding the minimal clinically important difference for the change in SST and %MPI. Postoperative x-rays were evaluated to assess the positions of the center of rotation and the greater tuberosity for each implant. RESULTS: Forty-four percent of the 103 patients were managed with CTAH while 56% were managed with RSA. Both arthroplasties resulted in clinically significant improvement. Patients having RSA improved from a mean preoperative SST score of 1.7 (interquartile range [IQR], 0.0-3.0) to a postoperative score of 6.3 (IQR, 2.3-10.0) (P < .01). Patients having CTAH improved from a preoperative SST score of 3.1 (IQR, 1.0-4.0) to a postoperative score of 7.6 (IQR, 5.0-10.) (P < .001). These improvements exceeded the minimal clinically important difference. Instability accounted for most of the RSA complications; however, it did not account for any CTAH complications. The postoperative position of the center of rotation and greater tuberosity on anteroposterior radiographs did not correlate with the clinical outcomes for either procedure. CONCLUSION: For 103 patients with CTA, clinically significant improvement was achieved with appropriately indicated CTAH and RSA. In view of the lower cost of the CTAH implant, it may provide a cost-effective alternative to RSA for patients with retained active elevation.

Arthroscopic Transosseous Rotator Cuff Repair.

Open transosseous rotator cuff repair (RCR) was the original benchmark surgical technique for RCR. The advent of arthroscopic and suture anchor technology shifted the paradigm from open to arthroscopic surgery. Although technological advances have progressed, they come at a cost. Suture anchor technology is expensive, optimal constructs have yet to be determined, and the technology may lead to challenging complications and revision scenarios. In more recent years, a return to transosseous bone tunnels has been described with new arthroscopic techniques, eliminating the need for suture anchors. The purpose of this article is to review the historical, biomechanical, clinical, and economic literature surrounding arthroscopic transosseous RCR.

Factors associated with success of ream-and-run arthroplasty at a minimum of 5 years.

BACKGROUND: Ream-and-run arthroplasty offers improvements in shoulder pain and function for patients with primary glenohumeral arthritis who wish to avoid limitations associated with a polyethylene glenoid component. Longer-term clinical outcome assessments of the ream-and-run procedure are sparse in the literature. This study aimed to present minimum 5-year functional outcomes in a large cohort following ream-and-run arthroplasty to determine factors associated with clinical success and reoperation. METHODS: Patients who underwent ream-and-run surgery with a minimum of 5 years of follow-up were identified through a retrospective review of a prospectively maintained database from a single academic institution. To assess clinical outcomes, the Simple Shoulder Test (SST) was administered and assessed to determine achievement of the minimal clinically important difference, as well as the necessity for open revision surgery. Factors associated with P < .1 on univariate analysis were included in multivariate analysis. RESULTS: Of 228 patients who consented to undergo long-term follow-up, 201 (88%) were included in our analysis (mean follow-up period, 7.6 ± 2.1 years). The average age was 59.4 ± 8.8 years, and 93% of patients were men. The majority of patients had a diagnosis of osteoarthritis (79%) or capsulorrhaphy arthropathy (10%). SST scores improved from a mean of 4.9 ± 2.5 preoperatively to a mean of 10.2 ± 2.6 at latest follow-up. The minimal clinically important difference in the SST score of 2.6 was reached by 165 patients (82%). Male sex (P = .020), nondiabetic status (P = .080), and lower preoperative SST score (P < .001) were included in a multivariate analysis. Male sex (P = .010) and lower preoperative SST score (P < .001) were associated with clinically important improvements in SST scores on multivariate analysis. Open revision surgery was required in 22 patients (11%). Younger age (P < .001), female sex (P = .055), and higher preoperative pain score (P = .023) were included in a multivariate analysis. Only younger age was predictive of open revision surgery (P = .003). CONCLUSIONS: Ream-and-run arthroplasty can provide significant and clinically important improvements in clinical outcomes at minimum 5-year follow-up. Successful clinical outcomes were significantly associated with male sex and lower preoperative SST scores. Reoperation was more common in younger patients.

Malpractice against shoulder surgeons: what the data say.

BACKGROUND: Thousands of orthopedic surgeons in the United State face medical malpractice claims annually; however, little is known regarding the common causes for litigation against shoulder surgeons. In addition, the current analysis does not take into consideration how surgical frequency affects the litigation likelihood. The purpose of our investigation was to identify the most common causes of litigation against shoulder surgeons in the United States adjusting for surgical frequency. METHODS: The VerdictSearch database was used using the search terms "medical malpractice," "shoulder," and "NOT cancer." Results were queried, and all studies pertaining to orthopedic shoulder surgery included. Data gathered included cause of lawsuit, indemnity paid, type of surgery performed, results of the cases, verdict or settlement, and, if applicable, technical error. A query of a multisurgeon institutional database was conducted to determine how frequently surgeries were performed. Then the frequency of litigation was adjusted by the procedure frequency to determine which surgery has the greatest likelihood to be litigated relative to rotator cuff surgery. RESULTS: Forty-five cases were included in our study. After adjusting for the procedure frequency, the most likely procedure to be litigated, relative to rotator cuff repair, was manipulation under anesthesia (MUA), 251 times more likely to be litigated, and washout/lavage procedures, 17 times more likely to be litigated. Injection and total shoulder arthroplasty were 23 and 14 times less likely to be litigated relative to rotator cuff repair, respectively. In addition, the average age of the patients was 47 years, and 53% of the cases involved a male plaintiff. The most commonly litigated procedures were rotator cuff repair (42%), MUA (13%), and humeral open reduction and internal fixation (9%). The most commonly cited symptoms for litigation against shoulder surgeons were pain (60%) and loss of range of motion (40%). Of the 45 cases, 44% ended in physician loss, with the average indemnity paid via verdict being $1,118,714 vs. $416,875 for settlement. CONCLUSIONS: This study identifies that MUA and lavage/washout procedures are much more likely to be litigated relative to rotator cuff repair. Rotator cuff repair is actually one of the least likely procedures to be litigated. Furthermore, settlement may represent a method of decreasing the indemnity paid for malpractice cases for which surgeons are implicated.

Biomechanical comparison of elbow stability constructs.

BACKGROUND: Despite surgical stabilization of complex elbow trauma, additional fixation to maintain joint congruity and stability may be required. Multiple biomechanical constructs include a static external fixator (SEF), a hinged external fixator (HEF), an internal joint stabilizer (IJS), and a hinged elbow orthosis (HEO). The optimal adjunct fixation to surgical reduction is yet to be determined. METHODS: Eight matched cadaveric upper extremities were tested in a biomechanical model. Anteroposterior stress radiographs were obtained of the elbow in full supination at 0° and 45° of elbow flexion with the weight of the hand serving as a varus load as the baseline. A 360° capsuloligamentous soft-tissue release was performed around the elbow. The biomechanical constructs were applied in the same sequential order: SEF, HEF, IJS, and HEO. For each construct, 0 kg (0-lb) and 2.3 kg (5-lb) of weight were applied to the distal arm. At both weights, radiographs were obtained with the elbow at 0° and 45° of flexion, with subsequent measurement of displacement, congruence at the ulnohumeral joint, and the ulnohumeral opening angle. Statistical analysis was performed to quantify the strength and stability of each construct. RESULTS: Compared with the control group at 0° with and without 2.3 kg (5-lb) of varus force and at 45° with and without 2.3 kg (5-lb) of varus force, no difference was noted in the medial ulnohumeral joint space, lateral ulnohumeral joint space, or ulnohumeral opening angle between the SEF, HEF, and IJS. The gap change after exertion of a 2.3-kg (5-lb) force between the control condition and application of each construct demonstrated no difference between the SEF, HEF, and IJS. Comparison among destabilized elbows showed no significant difference between the SEF, HEF, and IJS. The HEO catastrophically failed in each position at 0 kg (0-lb) of weight. CONCLUSION: The SEF, HEF, and IJS are neither superior nor inferior at maintaining elbow congruity with the weight of the arm and 2.3 kg (5-lb) of varus stress. The HEO did not provide additional stability to the unstable elbow.

Reliable Pain Relief But Variable Return to Play After Arthroscopic Elbow Debridement in Baseball Players.

PURPOSE: We sought to determine the rate of return to play (RTP) in baseball players following arthroscopic elbow debridement for the management of the symptomatic elbow. METHODS: A retrospective case series with prospectively collected data via questionnaire was conducted on all baseball players who underwent an arthroscopic elbow debridement, from July, 15, 2004 to November 1, 2017. A postoperative questionnaire was released at an average 7.25 year follow-up. Data collected included age, gender, laterality, preoperative diagnosis, range of motion, duration and characterization of symptoms, visual analog scale (VAS) pain score, complications, level of play, and RTP. RESULTS: Follow-up data were available on 18 baseball players. Average age was 19.7 years (range 16-24). Seventeen were pitchers, and 1 was a catcher. Level of play included 12 collegiate athletes, 2 high school athletes, 2 recreational athletes, 1 minor league athletes, and 1 major league athlete. Rate of RTP was 61% (11/18) with 6 returning to a greater level and 5 to an equal level. The length of time to RTP following surgery was most commonly within 6-8 months (44.4%, 8/18). Mean VAS pain score improved from 6.9 to 0.75 (P = <.001). 27.8% (5/18) had repeat surgery secondary to recurrent/persistent stiffness or heterotopic ossification. 77.8% (14/18) of patients rated their final outcome as either "very satisfied" (9/18), or "satisfied" (5/18). CONCLUSIONS: Pain can reliably be relieved following arthroscopic elbow debridement in baseball players. Although patient satisfaction may be high, patients do not always return to their previous level of play. Patients must be counseled on the risk of limited postoperative athletic capacity before the time of surgery. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

The effect of preoperative education on opioid consumption in patients undergoing arthroscopic rotator cuff repair: a prospective, randomized clinical trial-2-year follow-up.

BACKGROUND: With the recent opioid epidemic in the United States, measures by both government and medical providers are being taken to decrease the opioid dependence rate. Different methods have been proposed, including patient education and multimodal pain therapies. The purpose of this study was to determine whether preoperative opioid education reduces the risk of opioid dependence at 2 years following arthroscopic rotator cuff repair (ARCR). METHODS: This study was a 2-year follow-up of the 2018 Neer Award study that demonstrated the use of preoperative opioid education as a means to reduce postoperative opioid consumption after ARCR at 3-month follow-up. This was a prospective, single-center, single-blinded, parallel-group, 2-arm, randomized clinical trial with a 1:1 allocation ratio. To study the effect of preoperative opioid education on opioid dependence at 2 years, we randomized patients into 2 cohorts, a study cohort and a control cohort. Data were obtained with a review of prescription data-monitoring software and a patient telephone interview. RESULTS: Opioid education (P = .03; odds ratio, 0.37; 95% confidence interval, 0.14-0.90) was found to be an independent factor that is protective against opioid dependence. Study patients had a lower rate of opioid dependence (11.4%, 8 of 50) than control patients (25.7%, 18 of 50) (P = .05). Significantly fewer prescriptions were filled by study patients (mean, 2.9) than by control patients (mean, 6.3) (P = .03). Additionally, fewer pills were consumed by study patients (median, 60; interquartile range [IQR], 30, 132) than by control patients (median, 120; IQR, 30, 340) (P = .10). Finally, fewer morphine milligram equivalents were consumed by study patients (median, 375; IQR, 199, 1496) than by control patients (median, 725; IQR, 150, 2190) (P = .27). CONCLUSION: Our study found that patients who were preoperatively educated on opioid use were less likely to become opioid dependent at 2-year follow-up. Therefore, we demonstrated that opioid education does impart significant long-term benefits to patients undergoing ARCR.

Bias in Prospective Research and How to Avoid it.

Prospective research studies answer clinical questions via randomized control studies or prospective cohort studies. Bias is defined as any deviation from the truth when interpreting data. Broadly speaking, bias is categorized into 3 categories: selection bias, information bias, and confounding bias. Furthermore, misinterpretation of presented statistics in research studies causes acceptance of conclusions which may not necessarily be true. This paper identifies sources of bias in prospective research and instructions to avoid bias.

How to Write an Effective Materials and Methods Section for Clinical Studies.

The Materials and methods section of a research paper is oftentimes the first and easiest part to write. It details the steps taken to answer a research hypothesis, the success of which determines whether or not the study can be replicated. Arranging the section in chronological order, writing succinctly, and consistently using the third-person passive voice adds clarity and improves readability. Furthermore, utilizing headers, tables, and flow charts to break down difficult and complex experiments into logical subsections makes it easier for the reader to grasp complicated designs.

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.

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.

Tibialis Anterior Tendon Reconstruction Using Augmented Half-Thickness Tendon Segment Transposition.

Tibialis anterior tendon rupture causes substantial morbidity. The present study describes the outcomes of augmented, half-thickness tibialis anterior tendon segment transposition, a novel reconstruction technique. This was an institutional review board-approved retrospective review of 3 patients with surgically treated attritional distal rupture with 1-year follow-up. The postdebridement tendon defect prohibited primary repair and was managed by distal transposition of a half-thickness healthy segment. This repair was augmented with human acellular dermal matrix allograft (Graftjacket, Wright Medical Technology, Memphis, TN). The mean age was 68 years (range, 59-73 years). Mean interval between injury and surgery was 59.3 days (range, 15-146 days). All patients regained symmetrical range of motion, motor power, and the ability to heel walk. Mean pain scores improved from 4.6 (range, 2.5-8.5) preoperatively to 0.7 (range, 0-2) postoperatively. Mean Foot and Ankle Ability Measure scores increased from 30.6 (range, 23.8-43.8) preoperatively to 78.7 (range, 72.6-97.6) postoperatively. No postoperative complications occurred. One patient was satisfied and 2 were very satisfied with their outcome. Although limited, the present findings appear to indicate that this technique produces short-term clinical results comparable to those described for other techniques for tibialis anterior tendon reconstruction.
