Combined tibial deflexion osteotomy and anterior cruciate ligament reconstruction improves knee function and stability: A systematic review.

IMPORTANCE: Patients with excessive posterior tibial slope (PTS) may have higher risks of anterior cruciate ligament (ACL) reconstruction (ACL-R) failure, and clinical outcomes after revision of ACL-R procedures are typically poor. OBJECTIVE: This study aimed to perform a systematic review of the literature summarizing the clinical and radiological outcomes of the surgical treatment of ACL insufficiency in the setting of excessive PTS using a tibial deflexion osteotomy combined with ACL-R. EVIDENCE REVIEW: A systematic review of the literature was performed using PubMed, Cochrane Library, and OVID Medline databases from 1990 to present. Inclusion criteria were studies of outcomes of isolated tibial deflexion osteotomies performed with primary or revision ACL-R in the English language. Data extracted included study demographic information, type of tibial deflexion osteotomy and concomitant procedures, radiological outcomes, patient-reported outcome scores, and postoperative complications. FINDINGS: Six studies, with 133 knees were identified. All included studies were retrospective case series, with a weighted mean follow-up of 3.39 years. In 106 of 133 (79.7%) knees, tibial deflexion osteotomy was performed concomitantly with an ACL-R, whereas in 27 of 133 (20.3%) knees, the procedures were staged. 22, 45, and 66 of 133 knees (16.5%, 33.8%, and 49.6%) underwent primary, first revision, and second or greater revision ACL-R, respectively. Three of 133 (2.25%) knees demonstrated recurrent ACL graft failure at the final follow-up. On average, PTS decreased from 15.2° preoperatively to 7.1° postoperatively. The mean International Knee Documentation Committee, Lysholm, and Tegner scores increased from 42.5, 46.4, and 4.2 preoperatively to 71.8, 89.0, and 6.7 postoperatively. CONCLUSIONS: The results of this review suggest that combined ACL-R and tibial deflexion osteotomy may be effective in decreasing PTS and improving knee function and stability.

The subcoracoid distance is correlated with pain and internal rotation after reverse shoulder arthroplasty.

Background: A proposed etiology of anterior shoulder pain and limited internal rotation after reverse shoulder arthroplasty (RSA) is impingement of the humeral component on the coracoid or conjoint tendon. The primary goal of this study was to investigate radiographic surrogates for potential coracoid or conjoint tendon impingement and their relationship to postoperative pain and internal rotation after RSA. Methods: A retrospective review of a clinical registry was performed to identify patients with (1) primary RSA, (2) minimum 2-year clinical follow-up, and (3) satisfactory postoperative axillary lateral radiographs. The primary radiographic measurement of interest was the subcoracoid distance (SCD), defined as the distance between the posterior aspect of the coracoid and the anterior glenosphere. Additional measurements were as follows: anterior glenosphere overhang, posterior glenosphere overhang, native glenoid width, lateralization of glenosphere relative to the coracoid tip, lateralization shoulder angle, and distalization shoulder angle. The primary clinical outcome of interest was the 2-year postoperative Visual Analog Scale score. Secondary outcomes were (1) internal rotation (IR) defined by spinal level (IRspine), (2) IR at 90 degrees of abduction, (3) American Shoulder and Elbow Surgeons score, (4) forward flexion, and (5) external rotation at 0 degrees of abduction. Linear regression analyses were used to evaluate the relationship of the various radiographic measures on the clinical outcomes of interest. Results: Two hundred seventeen patients were included. There was a statistically significant relationship between the SCD and Visual Analog Scale scores: B = -0.497, P = .047. There was a statistically significant relationship between the SCD and IRspine: B = -1.667, P < .001. Metallic lateralization was also positively associated with improving IRspine; increasing body mass index was negatively associated. There was a statistically significant relationship between the SCD and IR at 90 degrees of abduction: B = 5.844, P = .034. Conclusion: For RSA with a 135° neck shaft angle and lateralized glenoid, the postoperative SCD has a significant association with pain and IR. Decreasing SCD was associated with increased pain and decreased IR, indicating that coracoid or conjoint tendon impingement may be an important and potentially under-recognized etiology of pain and decreased IR following RSA. Further investigations aimed toward identifying a critical SCD to improve pain and IR may allow surgeons to preoperatively plan component position to improve clinical outcomes after RSA.

Treatment of Coxa Profunda With Open Surgical Hip Dislocation, Rim Resection, Cam Resection, and Labral Reconstruction.

Coxa profunda presents a unique challenge in surgical treatment approach given global acetabular overcoverage. Arthroscopic treatment can be fraught with difficulty obtaining hip distraction for safe arthroscopic instrumentation, and limited arthroscopic access may prevent sufficient osseous resection of the excess acetabular rim. Although hip arthroscopy use has increased markedly over the past decades for all types of hip pathology, coxa profunda may represent one unique indication for surgical hip dislocation. This technique describes open surgical hip dislocation, rim resection, femoral osteoplasty, and labral reconstruction using anterior tibialis allograft for coxa profunda with combined-type femoroacetabular impingement syndrome and labral ossification.

Osteoporosis Screening Is Often Indicated but Overlooked Prior to Rotator Cuff Repair.

PURPOSE: To (1) report the percentage of patients undergoing rotator cuff repair (RCR) who were appropriately screened with dual-energy X-ray absorptiometry testing prior to surgery, if indicated, and (2) determine the percentage of patients properly prescribed osteoporosis medications within 6 months of surgery. METHODS: Consecutive patients aged 50 years or older who underwent elective RCR at a single tertiary-care center over a 1-year period were reviewed. Fracture risk was estimated using the Fracture Risk Assessment Tool (FRAX) with and without bone mineral density. The U.S. National Osteoporosis Foundation (NOF) criteria for screening and treatment were applied. Patients with acute fractures or revision surgery were excluded. RESULTS: Of the 218 patients included, 129 were women (58.1%). The mean age was 61.5 ± 7.2 years. One hundred thirty-one RCRs (60.1%) occurred within 3 months of injury. A total of 69 patients (31.7%) met the NOF criteria for bone mineral density screening. Of these patients, 23 (33.3%) were appropriately screened with a dual-energy X-ray absorptiometry scan. Primary care providers initiated bone health assessment in 18 of the 23 appropriately screened patients, with orthopaedic providers initiating the workup in 3 patients (13.0%). Thirty-two patients (14.7%) met the NOF criteria for pharmacologic management of osteoporosis. Of these patients, 5 (15.6%) were treated. Patients meeting the medication criteria were older (69.1 ± 7.7 years vs 60.2 ± 6.3 years, P < .001), had a lower body mass index (28.8 ± 6.1 vs 31.5 ± 6.5, P = .028), and had chronic rotator cuff tears (P = .015). CONCLUSIONS: Patients aged 50 years or older undergoing RCR are often not appropriately screened for osteoporosis. Even when appropriately screened, only 15.6% of patients meeting the indications for pharmacologic intervention for bone health optimization were prescribed appropriate medications. Although bone health optimization may or may not affect surgical timing, patient encounters related to rotator cuff tears can be used as an opportunity for providers to initiate osteoporosis screening and treatment protocols. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Creation of a Custom-Length, Humeral Antibiotic Cement Spacer for Use in Treatment of Shoulder Periprosthetic Joint Infection.

Periprosthetic joint infection of the shoulder is a challenging clinical situation to manage owing to the fastidious organisms often present and delayed clinical presentation. While several treatment options have been described, the mainstay of treatment remains a staged revision with the use of a humeral antibiotic cement spacer. Such spacers are commercially available or can be made by hand. When an extended humeral osteotomy is required to remove a well-fixed long stem humeral component, it may be advantageous to place an antibiotic spacer with a stem length approximately as long as the hardware being removed. This technique demonstrates creation of a custom length, humeral antibiotic cement spacer for use in treatment of shoulder periprosthetic joint infection.

The Effect of an Orthopaedic Surgeon's Attire on Patient Perceptions of Surgeon Traits and Identity: A Cross-Sectional Survey.

INTRODUCTION: In orthopaedic surgery, limited research is available addressing how attire, including white coats (WC) and feminine attire such as skirts, affects patient perceptions. It is unknown how surgeon appearance is associated with identification as a surgeon and perception of clinical skills, nor whether this differs between male and female surgeons. METHODS: An image-based survey was offered to all adult patients in four orthopaedic surgeons' sport medicine or foot and ankle clinics. Respondents viewed 10 photos of male and female models in varying attire and identified that individual's most likely role on the healthcare team. Then, in 10 photos pairs, respondents selected which surgeon showed more competence, ability to excel in performing the physical components of surgery, likelihood to provide a good surgical outcome, and trustworthiness. RESULTS: Two hundred thirty-eight patients participated in the survey. Men were identified as surgeons significantly more frequently than women in similar clothing (P < 0.05) for all attire except a business attire without a WC (men: 18.2% vs women: 11.2%; P = 0.252). Patients ranked physicians wearing a WC with any attire as more competent and more likely to give a good surgical outcome than those without (all P < 0.005). Patients found women in feminine attire significantly less likely to excel in performing the physical parts of surgery than women in scrubs (P = 0.001). DISCUSSION: Women surgeons who wear feminine business attire instead of scrubs may be perceived less able to perform the physical work of operating, but are otherwise rated comparably with their peers, both male and female. Surgeons wearing WC are generally perceived more favorably than those without WC, an effect that is magnified for perceptions of competence for female surgeons. Men are more readily identified as surgeons than women when wearing a similar attire, except for a business attire without WC. There are continuing differences in how patients perceive male and female orthopaedic surgeons based on their attire.

Suture Technique Influences the Biomechanical Integrity of Pectoralis Major Repairs.

Pectoralis major ruptures occur in large, muscular individuals, and repair constructs may experience significant tension. Four different suture techniques were evaluated biomechanically to determine the effect of suture technique on optimizing fixation strength. Forty fresh-frozen cadaveric shoulders were repaired using endosteal buttons. The control group was repaired with #2 polyblend suture in a modified Mason-Allen stitch configuration. The triple group was repaired using the same suture and configuration, but with the addition of triple-loaded buttons. The configuration group was repaired using the same suture in a Krackow/Bunnell configuration. The tape group was repaired using 2-mm polyethylene tape and #5 polyblend suture in the Krackow/Bunnell configuration. Under cyclic loading, there was no significant difference between groups. Under load-to-failure testing, the tape group withstood a significantly greater maximum load (726.0±90.0 N) than the control and triple groups (330.2±20.2 and 400.2±35.2 N, respectively; P<.005), and similar load to the configuration group (509.9±68.6 N; P=.16). The configuration group failed via suture breakage (9/10); the other groups failed via suture pullout, in which suture pulled through tendon (26/30). Pectoralis major repair in a running, locked configuration appears to improve biomechanical performance by preventing suture pullout. Use of a polyethylene tape construct demonstrates the potential for improved failure loads, but its role remains undefined.

Subpectoral biceps tenodesis for bicipital tendonitis with SLAP tear.

The purpose of this study was to evaluate the outcomes of patients undergoing subpectoral biceps tenodesis for bicipital tendonitis with a superior labral anterior-posterior (SLAP) tear. Patients undergoing primary subpectoral biceps tenodesis for arthroscopically confirmed SLAP tears with signs or findings of bicipital tendonitis were included. An independent observer collected data prospectively as part of a data repository, which was then analyzed retrospectively. Primary outcome measures were the American Shoulder and Elbow Surgeons (ASES) score and pain relief via visual analog scale (VAS). Secondary outcome measures included the Simple Shoulder Test (SST), Constant, Single Assessment Numeric Evaluation (SANE), and Short Form 12 (SF-12) scores. Twenty-eight patients with a mean±SD age of 43.7±13.4 years and a mean±SD follow-up of 2.0±1.0 years met inclusion criteria. Workers' compensation was involved with 43% of cases, and 46% of the included patients were manual laborers. Eight (32%) patients were athletes, and 88% of the athletes were overhead athletes. Intraoperatively, 15 (54%) patients had type I SLAP tears, 10 (36%) had type II SLAP tears, 1 (3%) had a type III SLAP tear, and 2 (7%) had type IV SLAP tears. Significant improvements were seen in the following outcome measures pre- vs postoperatively: ASES score (58±23 vs 89±18; P=.001), SST score (6.3±3.6 vs 10.6±3.3; P=.001), SANE score (54±24 vs 88±25; P=.003), VAS score (3.8±2.0 vs 1.1±1.8; P=.001), SF-12 overall score (35±6 vs 42±6; P=.001), and SF-12 physical component score (39±6 vs 50±10; P=.001). Overall satisfaction was excellent in 80% of patients. Subpectoral biceps tenodesis demonstrates excellent clinical outcomes in select patients with SLAP tears. [Orthopedics. 2015; 38(1):e48-e53.].

Feasibility of an osteochondral allograft for biologic glenoid resurfacing.

BACKGROUND: Concerns regarding insufficient press fit and glenoid vault cortical blowout make glenoid osteochondral allografting uncommon. We used 3-dimensional computed tomography modeling to test glenoid osteochondral allografting feasibility. MATERIALS AND METHODS: Sixteen cadaveric shoulders without osteoarthritis underwent computed tomography scans to create 3-dimensional models. The diameter of circular center-based reaming reaching the medial endosteal surface at depths of 4, 6, and 8 mm and the clock face position of the most shallow points were calculated. Demographic factors associated with graft diameter were analyzed by step-wise multiple regressions. RESULTS: Shallower graft depths allowed larger graft diameters (P < .001). With a graft depth of 4 mm, 56% of glenoids allowed 20-mm-diameter grafts and 94% accommodated 16-mm grafts versus 31% and 75%, respectively, for a graft depth of 6 mm and 13% and 38%, respectively, for a graft depth of 8 mm. Increasing graft depth decreased graft glenoid coverage: mean coverage was 51.9% ± 12.2%, 36.3% ± 12.9%, and 23.8% ± 14.2% for 4-, 6-, and 8-mm depths, respectively. The glenoid's most shallow point was between the 1:30 clock face position and 3-o'clock position in reference to a right shoulder in 69%, 75%, and 44% of glenoids for 4-, 6-, and 8-mm depths, respectively. Although female gender, patient height, and glenoid height and width were associated with graft diameter, multiple regression analysis showed that patient height was the only independent variable associated with accommodated graft diameter at depths of 4, 6, and 8 mm (P = .001, P = .001, and P = .003, respectively). CONCLUSION: Most glenoids support center-based grafts of 16 to 20 mm in diameter at a depth of 4 mm, covering an average of 51.9% of the glenoid. Accommodated graft size decreases as reaming depth increases.

Clinical outcomes of hemiarthroplasty and biological resurfacing in patients aged younger than 50 years.

BACKGROUND: Total shoulder arthroplasty as a treatment for glenohumeral degenerative joint disease is well accepted but has been less predictable with regard to outcomes and durability in a younger aged population, typically aged younger than 50 years. This younger population has a greater potential for glenoid component loosening. This has led surgeons to perform hemiarthroplasty or hemiarthroplasty with biological resurfacing of the glenoid in an effort to avoid the potential problems with a polyethylene glenoid and obtain durable and acceptable results for these patients. METHODS: The study included 44 patients, with 23 undergoing hemiarthroplasty alone and 21 undergoing hemiarthroplasty with biological resurfacing of the glenoid. All patients were aged younger than 50 years. Preoperative diagnoses, comorbidities, demographics, and range of motion were collected. Preoperative and postoperative radiographs were obtained. Preoperative and postoperative objective scoring measures (Single Assessment Numeric Evaluation, American Shoulder and Elbow Surgeons score, visual analog scale, Simple Shoulder Test, Constant-Murley) were used. RESULTS: Mean follow-up was 3.8 years for the hemiarthroplasty group and 3.6 years for the biological resurfacing group. Six patients in the hemiarthroplasty and 12 patients in the biological resurfacing group were considered failures due to revision surgery or an American Shoulder and Elbow Surgeons score <50. The hemiarthroplasty group had significantly better visual analog scale and Single Assessment Numeric Evaluation scores. CONCLUSIONS: There was a significant failure rate in the hemiarthroplasty and the biologic resurfacing groups compared with results in the literature. Improved outcomes and lower failure rates were observed in the hemiarthroplasty group compared with the biological resurfacing group in this study.

Subpectoral biceps tenodesis for failed type II SLAP repair.

Superior labrum anterior-posterior lesions are a common cause of shoulder pain. The diagnosis, classification, and indications for surgical intervention remain controversial, and mixed outcomes are associated with primary repair. Given the increasing prevalence of primary superior labrum anterior-posterior repairs in the United States, more surgeons will need to treat patients with poor primary results. A retrospective review of prospectively collected data was performed on patients who underwent subpectoral biceps tenodesis for failed type II superior labrum anterior-posterior repair by a single surgeon between January 2008 and December 2011. Primary outcome variables included pain via the visual analog scale, American Shoulder and Elbow Surgeons score, and Short Form 12 score. Secondary outcome variables included the Simple Shoulder Test and Single Assessment Numeric Evaluation scores. Demographic and intraoperative information was recorded for each patient. A paired t test statistical analysis was performed with a P value less than .05 considered statistically significant. A total of 11 patients met the inclusion criteria. Of these patients, 9 (82%) completed postoperative surveys at a mean 26-month follow-up. Mean visual analog scale scores improved from 4.1 to 2.5 (P=.03), Simple Shoulder Test scores from 5.4 to 9.3 (P=.005), American Shoulder and Elbow Surgeons scores from 54.5 to 78.0 (P=.002), and Single Assessment Numeric Evaluation scores from 42.5 to 70.4 (P=.001). Mean SF-12 (physical component) improved from 35.5 to 47.9 (P=.018). No failures or peri- or postoperative complications occurred. No patients required additional surgery. The findings suggest that subpectoral biceps tenodesis as a salvage for failed type II superior labrum anterior-posterior repair demonstrates improved results. Larger scale comparative studies are required to justify this technique.
