RESUMO

PURPOSE: The purpose of this study was to compare the percentage of native femoral anterior cruciate ligament (ACL) footprint covered by the 2 most clinically relevant bone plug/graft orientations used with interference screw fixation in ACL reconstruction. A secondary purpose was to assess whether a transtibial or tibia-independent drilling technique would affect this outcome. METHODS: Five matched pairs of cadaver knees were used. Each matched pair had 1 knee assigned to a 10-mm femoral socket prepared via a transtibial (TT) drilling technique and the other via an anteromedial (AM) drilling technique. The bone plug of each graft was press-fitted into the femoral socket with the graft collagen in 2 distinct clinically relevant orientations (collagen inferior or posterior). The digitized graft collagen cross-sectional area (CSA) in each orientation was overlaid onto the native femoral ACL footprint CSA to generate a percentage of native ACL footprint covered by graft collagen. RESULTS: The average native ACL femoral footprint CSA was 110.5 ± 9.1 mm2, with no difference between knees assigned to TT or AM drilling (112.6 ± 2.7 vs 108.4 ± 13.0 mm2, P = .49). The average femoral socket CSA was 95.4 ± 8.7 mm2, with no difference between TT and AM tunnels (95.5 ± 9.9 vs 95.3 ± 8.4 mm2, P = .96). There was no difference between the percentage of native footprint covered between TT and AM sockets (76.8% ± 7.8% vs 82.2% ± 13.7%, P = .47). Irrespective of drilling technique, there was significantly greater native ACL footprint covered by graft collagen when the bone plug was oriented with graft collagen inferior rather than posterior (75.6% ± 6.3% vs 65.4% ± 11.4%, P = .02). CONCLUSION: Orienting the femoral bone plug such that the graft collagen is inferior rather than posterior significantly increases native ACL femoral footprint coverage in bone-patellar tendon-bone ACL reconstruction. This effect is consistent across AM and TT drilling techniques. CLINICAL RELEVANCE: Surgeons attempting to restore an anatomic ACL footprint should consider bone plug-graft orientation when performing ACL reconstruction. STUDY DESIGN: Controlled laboratory study.

RESUMO

PURPOSE: To report outcomes after arthroscopic 360° capsular release in the lateral decubitus position for idiopathic glenohumeral adhesive capsulitis without manipulation under anesthesia. METHODS: A retrospective case series of patients who underwent arthroscopic capsular release in the lateral decubitus position for idiopathic adhesive capsulitis with minimum 2-year follow-up was conducted. Patient demographics, preoperative range of motion (ROM), postoperative ROM, and the postoperative outcome scores, visual analog scale for pain, Single Assessment Numeric Evaluation, Simple Shoulder Test, and American Shoulder and Elbow Surgeons scores, were recorded. Complications and reoperations were recorded. Paired t-tests were used to compare preoperative and postoperative ROM, with P < .05. RESULTS: Overall, 43 patients were identified, of whom 10 were excluded because of post-traumatic etiology. Of the remaining 33 patients, 27 (81.8%) completed a minimum follow-up of 2 years. The mean age was 54.8 with a standard deviation of 7.4 years and 78% were female, with the duration of symptoms of 16.2 ± 21.0 (range, 3-125) months. Hypothyroidism was present in 7% and diabetes present in 30%. Active forward flexion improved from 115.0° ± 21.9° to 156.2° ± 16.1° at the final follow-up (mean difference, 41.2; 95% confidence interval [33.7, 48.7]; P < .001). Active external rotation with the arm adducted improved from 28.1° ± 16.3° preoperatively to 56.8° ± 15.7° at the final follow-up (mean difference, 27.7; 95% confidence interval [19.1, 36.3]; P < .001). Significant ROM improvements were seen even as early as 2 weeks postoperatively (P < .001). Two patients (7%) had manipulation under anesthesia postoperatively due to early recurrent stiffness 4 to 6 weeks after arthroscopic capsular release. There were no revision surgeries or complications. CONCLUSIONS: Arthroscopic 360° capsular release in the lateral decubitus position for idiopathic adhesive capsulitis results in a significant early and lasting improvement in ROM, excellent functional outcomes, and low revision and complication rates. LEVEL OF EVIDENCE: Level IV, retrospective case series.

RESUMO

STUDY DESIGN: Retrospective study. OBJECTIVE: Evaluate the effect of age on the efficacy of allograft/demineralized bone matrix (DBM) enriched with concentrated bone marrow aspirate (BMA) in posterolateral lumbar fusions (PLFs). SUMMARY OF BACKGROUND DATA: Cell-based therapies such as concentrated BMA have been developed as a potential alternative to iliac crest bone graft (ICBG). BMA contains mesenchymal stem cells (MSCs) and growth factors that can confer osteogenic and osteoinductive potential to osteoconductive scaffolds such as DBM/allograft. To date, no studies have examined the role of age on fusion outcomes when BMA is utilized despite the well-established deleterious effects of advanced age on bone marrow and MSC potential. MATERIALS AND METHODS: Fifty-one patients that underwent PLF were divided into 3 groups. Group A (n=14) composed of patients age 65 years and older who received BMA with DBM. Group B (n=17) consisted of patients younger than 65 years of age who received BMA with DBM. Group C (n=20) composed of patients age 65 years and older who received ICBG. Fusion rates and clinical outcomes were assessed. RESULTS: Fusion was significantly lower in group A (35.7%) compared with both groups B (76.4%) and C (80%) (A vs. B, P=0.03; A vs. C, P=0.01). There were no differences in clinical outcomes among all groups except for pseudarthrosis which occurred in 28.6% of patients in group A compared with none and 5% of patients in groups B and C, respectively (A vs. B, P=0.03; A vs. C, P=0.13). CONCLUSIONS: Elderly patients undergoing PLF using DBM enriched with BMA achieved lower radiographic fusion success compared with their nonelderly counterparts and compared with elderly patients that had fusion with ICBG. This may be partly due to the effect of advanced age on MSC potential.

RESUMO

PURPOSE: To determine the patient compliance in completing electronically administered patient-reported outcome (PRO) scores following shoulder arthroscopy, and to determine if dedicated research assistants improve patient compliance. METHODS: Patients undergoing arthroscopic shoulder surgery from January 1, 2014, to December 31, 2014, were prospectively enrolled into an electronic data collection system with retrospective review of compliance data. A total of 143 patients were included in this study; 406 patients were excluded (for any or all of the following reasons, such as incomplete follow-up, inaccessibility to the order sets, and inability to complete the order sets). All patients were assigned an order set of PROs through an electronic reporting system, with order sets to be completed prior to surgery, as well as 6 and 12 months postoperatively. Compliance rates of form completion were documented. Patients who underwent arthroscopic anterior and/or posterior stabilization were excluded. RESULTS: The average age of the patients was 53.1 years, ranging from 20 to 83. Compliance of form completion was highest preoperatively (76%), and then dropped subsequently at 6 months postoperatively (57%) and 12 months postoperatively (45%). Use of research assistants improved compliance by approximately 20% at each time point. No differences were found according to patient gender and age group. Of those completing forms, a majority completed forms at home or elsewhere prior to returning to the office for the clinic visit. CONCLUSIONS: Electronic administration of PRO may decrease the amount of time required in the office setting for PRO completion by patients. This may be mutually beneficial to providers and patients. It is unclear if an electronic system improves patient compliance in voluntary completion PRO. Compliance rates at final follow-up remain a concern if data are to be used for establishing quality or outcome metrics. LEVEL OF EVIDENCE: Level IV, case series.

RESUMO

PURPOSE: To compare the initial fixation stability, failure strength, and mode of failure of 5 different screw types and fixation methods commonly used for the classic Latarjet procedure. METHODS: Thirty-five fresh-frozen cadaveric shoulder specimens were allocated into 5 groups. A 25% anteroinferior glenoid defect was created, and a classic Latarjet coracoid transfer procedure was performed. All grafts were fixed with 2 screws, differing by screw type and/or fixation method. The groups included partially threaded solid 4.0-mm cancellous screws with bicortical fixation, partially threaded solid 4.0-mm cancellous screws with unicortical fixation, fully threaded solid 3.5-mm cortical screws with bicortical fixation, partially threaded cannulated 4.0-mm cancellous screws with bicortical fixation, and partially threaded cannulated 4.0-mm captured screws with bicortical fixation. All screws were stainless steel. Outcomes included cyclic creep and secant stiffness during cyclic loading, as well as load and work to failure during the failure test. Intergroup comparisons were made by a 1-way analysis of variance. RESULTS: There were no significant differences among different screw types or fixation methods in cyclic creep or secant stiffness after cyclic loading or in load to failure or work to failure during the failure test. Post-failure radiographs showed evidence of screw bending in only 1 specimen that underwent the Latarjet procedure with partially threaded solid cancellous screws with bicortical fixation. The mode of failure for all specimens analyzed was screw cutout. CONCLUSIONS: In this biomechanical study, screw type and fixation method did not significantly influence biomechanical performance in a classic Latarjet procedure. When performing this procedure, surgeons may continue to select the screw type and method of fixation (unicortical or bicortical) based on preference; however, further studies are required to determine the optimal method of treatment. CLINICAL RELEVANCE: Surgeons may choose the screw type and fixation method based on preference when performing the Latarjet procedure.

RESUMO

BACKGROUND: Increasing emphasis is placed on patient-reported outcomes (PROs) after common orthopaedic procedures as a measure of quality. When considering PRO utilization in patients with rotator cuff tears, several different PROs exist with varying levels of accuracy and utilization. HYPOTHESIS/PURPOSE: Understanding which disease-specific PRO may be most efficiently administered in patients after rotator cuff repair may assist in promoting increased patient and physician adoption of these useful scores. Using a novel assessment criterion, this study assessed all commonly used rotator cuff PROs. We hypothesize that surveys with fewer numbers of questions may remain comparable (with regard to comprehensiveness) to longer surveys. STUDY DESIGN: Systematic review. METHODS: Commonly utilized rotator cuff PROs were analyzed with regard to number of survey components, comprehensiveness, and efficiency. Comprehensiveness (maximum score, 11) was scored as the total number of pain (at rest/baseline, night/sleep, activities of daily living [ADLs], sport, and work) and functional (strength, motion/stiffness, and ability to perform ADLs, sport, and work) metrics included, along with inclusion of quality of life/satisfaction metrics. Efficiency was calculated as comprehensiveness divided by the number of survey components. RESULTS: Sixteen different PROs were studied. Number of components ranged from 5 (University of California at Los Angeles score [UCLA]) to 36 (Short Form-36 [SF-36], Japanese Orthopaedic Association score [JOA]). The Quality of Life Outcome Measure for Rotator Cuff Disease (RC-QoL) included all 5 pain components, while 7 PROs contained all 5 functional components. Ten PROs included a quality of life/satisfaction component. The most comprehensive scores were the RC-QoL (score, 11) and Penn (score, 10), and the least comprehensive score was the Marx (score, 3). The most efficient PROs were the UCLA, the Quick Disabilities of the Arm, Shoulder, and Hand score (QuickDASH), and Constant scores. The least efficient scores were the JOA and SF-36 scores. CONCLUSION: Many commonly utilized PROs for rotator cuff tears are lacking in comprehensiveness and efficiency. Continued critical assessment of PRO quality may help practitioners identify the most comprehensive and efficient PRO to incorporate into daily clinical practice.

RESUMO

Patient reported outcomes (PROs) serve an integral role in clinical research by helping to determine the impact of clinical care as experienced by the patient. With recent initiatives in health care policy and pay for performance, outcome reporting is now recognized as a policy-driven requirement in addition to a clinical research tool. For outcome measures to satisfy these regulatory requirements and provide value in understanding disease outcomes, they must be responsive and efficient. Recent research has uncovered certain concerns regarding traditional PROs in patients with upper extremity disability and injury. These include lack of consensus regarding selection of PROs for a given diagnoses, inconsistent techniques of administration of the same PROs, and the administrative burden to patients and providers of completing these forms. To address these limitations, emphasis has been placed on streamlining the outcomes reporting process, and, as a result, the National Institutes of Health (NIH) created the Patient Reported Outcomes Measurement Information System (PROMIS). PROMIS forms were created to comprehensively and efficiently measure outcomes across multiple disease states, including orthopedics. These tools exist in computer adaptive testing and short forms with the intention of more efficiently measuring outcomes compared with legacy PROs. The goals of this review are to highlight the main components of PROMIS reporting tools and identify recent use of the scores in the upper extremity literature. The review will also highlight the research and health policy potentials and limitations of implementing PROMIS into everyday orthopedic practice.

RESUMO

Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The beach chair position is a reliable, safe, and effective position to perform nearly all types of shoulder arthroscopic procedures. The advantages of the beach chair position include the ease of setup, limited brachial plexus stress, increased glenohumeral and subacromial visualization, anesthesia flexibility, and the ability to easily convert to an open procedure. This position is most commonly used for rotator cuff repair, subacromial decompression, and superior labrum anterior-to-posterior repair procedures. To perform arthroscopy surgery in the beach chair position successfully, meticulous care during patient positioning and setup must be taken. In this Technical Note, we describe the necessary steps to safely and efficiently prepare patients in the beach chair position for arthroscopic shoulder surgery.

RESUMO

Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The lateral decubitus position allows for excellent exposure to all aspects of the glenohumeral joint and is therefore frequently employed in procedures such as stabilization, in which extensive visualization of the inferior and posterior aspects of the joint is required. Improved visualization is imparted due to applied lateral and axial traction on the operative arm, which increases the glenohumeral joint space. To perform arthroscopy surgery in the lateral decubitus position successfully, meticulous care during patient positioning and setup must be taken. In this Technical Note, we describe the steps required to safely, efficiently, and reproducibly perform arthroscopic shoulder surgery in the lateral decubitus position.

RESUMO

Hamstring tendon autograft remains a popular graft choice for anterior cruciate ligament (ACL) reconstruction. Although there are a variety of autograft and allograft options available for ACL reconstruction, advantages of hamstring tendon autografts include decreased postoperative knee pain and an overall easier surgical recovery compared with bone patellar tendon bone autograft. In addition, 4-stranded (quadruple) hamstring grafts are among the strongest grafts biomechanically (at time equals zero). Although the technique of hamstring autograft harvest is relatively straightforward, it is critical to pay attention to several technical steps to avoid iatrogenic neurovascular damage as well as to avoid premature amputation of the graft while using a tendon stripper. In this Technical Note, we describe a technique of hamstring autograft harvest for ACL reconstruction for a quadruple (4-strand) hamstring graft using the gracilis and semitendinosus tendons.

RESUMO

BACKGROUND: Multiple studies have demonstrated that a significant amount of variability exists in various demineralized bone matrix (DBM) formulations, which casts doubts on its reliability in consistently promoting fusion. Bone marrow aspirate (BMA) is a cellular based graft that contains mesenchymal stem cells (MSCs) and growth factors can confer osteogenic and osteoinductive potential to DBM. The goal of this study was to describe the outcome of DBM enriched with concentrated BMA in patients undergoing combined lumbar interbody and posterolateral fusion. METHODS: Eighty patients with a minimum of 12 months of follow-up were evaluated. Fusion and rates of complication were evaluated. Functional outcomes were assessed based on the modified Odom's criteria. Multiple logistic regression analysis was used to examine the effects of independent variables on fusion outcome. RESULTS: The overall rate of solid fusion (i.e patients with both solid posterolateral and interbody fusion) was 81.3% (65/80). Specifically, the radiographic evidence of solid posterolateral and interbody fusions were 81.3% (65/80) and 92.5% (74/80), respectively. Seven (8.75%) patients developed hardware-related complications, 2 (2.5%) patients developed a postoperative infection and 2 (2.5%) patients developed clinical pseudarthrosis. Charlson comorbidity index (CCI) scores of 3 and 4 were associated with non-solid unions (CCI-3, p = 0.048; CCI-4, p = 0.03). Excellent or good outcomes were achieved in 58 (72.5%) patients. CONCLUSIONS: Patients undergoing lumbar fusion using an enriched bone graft containing concentrated BMA added to DBM can achieve successful fusion with relatively low complications and good functional outcomes. Despite these findings, more studies with higher level of evidence are needed to better understand the efficacy of this promising graft option.

RESUMO

Idiopathic adhesive capsulitis of the shoulder is a relatively common condition that results in pain and loss of motion due to capsular thickening and fibrosis. Most cases are successfully treated with conservative management including physical therapy and intra-articular steroid injections. If conservative management fails, arthroscopic capsular release allows precise release of thickened capsular tissue with a lower risk of complications and less soft-tissue trauma than manipulation under anesthesia alone. Arthroscopic capsular release in the beach-chair position typically requires some degree of manipulation to release the inferior capsule, which is often not visualized intraoperatively. In this technique article and video, we describe and demonstrate a technique of arthroscopic capsular release in the lateral decubitus position, providing a clear view of the inferior capsule, which facilitates a complete, 360° capsular release and mitigates the need for any manipulation under anesthesia.

RESUMO

The preoperative assessment of anterior glenoid bone loss is a critical step in surgical planning for patients with recurrent anterior glenohumeral instability. The structural integrity of the glenoid has been identified as one of the most important factors influencing the success of operative repair. The currently accepted gold standard for glenoid structural assessment among most orthopaedic surgeons is the use of 3-dimensional reconstructed computed tomography images with the humeral head digitally subtracted, yielding an en face sagittal oblique view of the glenoid. This view allows for evaluation of glenoid morphology and quantitative assessment of glenoid bone loss. In this article, we describe the practical application of ImageJ software (National Institutes of Health, Bethesda, MD) to quantify the amount of glenoid bone loss reported as a percentage of either total surface area or diameter. The following equations are used in this technical note for the diameter-based method and surface area method, respectively: Percent bone loss = (Defect width/Diameter of inferior glenoid circle) × 100% and Percent bone loss = (Defect surface area/Surface area of inferior glenoid circle) × 100%.

RESUMO

The Bankart lesion, in which the anteroinferior labrum is detached from the glenoid, is the critical anatomic lesion in the majority of patients with anterior glenohumeral instability. Some patients with anterior glenohumeral instability will have Bankart lesions with posterior extension beyond the 6-o'clock position, and achieving anatomic labral repair in these cases can present a technical challenge. In our experience, the lateral decubitus position and use of accessory portals allow superior visualization of the inferior half of the glenohumeral joint for glenoid and labral preparation, anchor placement, and suture management. The use of double-loaded suture anchors at the inferior glenoid provides multiple points of fixation at this challenging location while limiting the number of anchors required. The purpose of this article is to present a simple and reproducible technique for arthroscopic repair of Bankart lesions with posterior extension, emphasizing the use of accessory 5-o'clock trans-subscapularis and 7-o'clock portals.

RESUMO

PURPOSE: Cell-based therapies such as concentrated bone marrow aspirate (BMA) with allograft and demineralized bone matrix (DBM) have been developed as a potential alternative to iliac crest bone graft (ICBG) in spinal fusion. BMA contains mesenchymal stem cells (MSCs) and growth factors that confer osteogenic and osteoinductive potential to osteoconductive scaffolds like allograft and DBM. It is well established that there is an age-related decline in bone marrow MSC population and efficacy. This might be problematic in spine arthrodesis when utilizing BMA derived from elderly patients as a fusion aide. The goal of this study was to describe the outcomes of concentrated BMA with allograft and DBM in elderly patients undergoing posterolateral and interbody lumbar fusion. METHODS: Thirty-one patients, age 65 and older, with a minimum of 12 months follow-up underwent combined primary posterolateral and transforaminal lumbar interbody fusion. Radiographic fusion, complications, reoperation rates and clinical outcomes were assessed. Multiple logistic regression analysis was used to examine the effects of variables such as patient age, gender, smoking, osteoporosis, Charlson co-morbidity index score, single versus multilevel fusion, length of hospital stay, and length of follow-up time on fusion outcome. RESULTS: The overall rate of a solid fusion (i.e. the concomitant presence of solid posterolateral and interbody fusion in a patient) was 83.9 % (26/31). Specifically, radiographic evidence of a successful posterolateral fusion was 83.9 % (26/31) while the radiographic evidence of a successful interbody fusion was 96.8 % (30/31). Using logistic regression analysis, none of the variables of interest had an association with non-solid unions. One (3.2 %) patient developed a seroma and one (3.2 %) patient developed clinical pseudarthrosis. None of the patients developed hardware-related complications or graft donor site morbidities. Five (16.1 %) patients required reoperation. Excellent or good results were achieved in 83.9 % of patients. CONCLUSIONS: Despite the concerns of reduced fusion potential in elderly patients, autologous concentrated BMA mixed with allograft and DBM in posterolateral and interbody fusions can achieve successful fusion rates with good clinical outcomes and low complication rates.
