Abstract
Background Elbow arthroscopy is a difficult surgical technique. Objective metrics can be used to improve safe and effective training in elbow arthroscopy. Force exerted on the elbow tissue during arthroscopy can be a measure of safe tissue manipulation. The purpose of this study was to determine the force magnitude and force direction used by experts during arthroscopic elbow navigation in cadaveric specimens and assess their applicability in elbow arthroscopy training. Methods Two cadaveric elbows were mounted on a Force Measurement Table (FMT) that allowed 3-dimensional measurements (x-, y-, and z-plane) of the forces exerted on the elbow. Five experts in elbow arthroscopy performed arthroscopic navigation once in each of two cadaveric elbows, navigating through the posterior, posterolateral and anterior compartment in a standardized fashion with visualization of three to four anatomic landmarks per compartment. The total absolute force (Fabs) and force direction exerted (α and β) on the elbow during arthroscopy were recorded. α being the angle in the horizontal plane and β being the angle in the vertical plane. The 10th–90th percentiles of the data were used to set threshold levels for training. Results The median Fabs was 24 N (19 N – 30 N), 27 N (20 N – 33 N) and 29 N (23 N – 32 N) for the posterior, posterolateral and anterior compartment, respectively. The median α was - 29° (- 55° – 5°), - 23° (- 56° – -1°) and 4° (- 22° – -18°) for the posterior, posterolateral and anterior compartment, respectively. The median β was - 71° (- 80° – -65°), - 76° (- 86° – -69°) and - 75° (- 81° – -71°) for the posterior, posterolateral and anterior compartment, respectively. Conclusion Expert data on force magnitude and force direction exerted on the elbow during arthroscopic navigation in cadaveric specimens were collected. The proposed maximum allowable force of 30 N (smallest 90th percentile of Fabs) exerted on the elbow tissue, and the 10th–90th percentile range of the force directions (α and β) for each compartment may be used to provide objective feedback during arthroscopic skills training.

Abstract
BACKGROUND Arthroscopic debridement and microfracture are considered the primary surgical treatment for capitellar osteochondritis dissecans (OCD). Healing of the subchondral bone plays an essential role in cartilage repair, while lack of healing is related to the development of osteoarthritis. To date, it is unknown to what extent healing of the subchondral bone occurs after this technique in the elbow. PURPOSE To analyze defect size changes and subchondral bone healing with computed tomography (CT) after arthroscopic debridement and microfracture for advanced capitellar OCD. STUDY DESIGN Case series; Level of evidence, 4. METHODS Between 2009 and 2016, 67 patients underwent arthroscopic debridement and microfracture for advanced capitellar OCD. Fifty-four patients (81% follow-up rate) with CT scans were included (mean ± SD: preoperative, 4.0 ± 1.7 months; postoperative, 29 ± 9.0 months). OCD defect size was assessed by measuring the largest diameter in 3 directions: medial-lateral direction (coronal plane) and anterior-posterior direction and depth (both in sagittal plane). Healing of the OCD was divided into 3 categories: good-complete osseous union or ossification; fair-incomplete osseous union or ossification but improved; poor-no changes between pre- and postoperative scans. Postoperative clinical outcome was assessed with the Oxford Elbow Score (OES) at the same time as the postoperative CT scan. RESULTS There were 30 female and 24 male patients (age, 15.7 ± 3.2 years). Defect size decreased ( P < .001) in all 3 directions (medial-lateral × anterior-posterior × depth) at 29 ± 9.0 months: preoperatively, 7.9 ± 2.8 × 8.0 ± 3.2 × 4.1 ± 1.5 mm; postoperatively, 3.5 ± 3.3 × 4.0 ± 3.5 × 1.6 ± 1.4 mm. Healing of the subchondral bone was graded as good in 19 defects (35%), fair in 27 (50%), and poor in 8 (15%). The mean postoperative OES score was 40 ± 8.4. Neither postoperative defect size nor healing grade correlated with the OES ( P > .05). CONCLUSION Arthroscopic debridement and microfracture for advanced capitellar OCD result in improved (ie, decreased) defect size at a mean follow-up of 29 months, both in width and in depth. Healing of the subchondral bone was either good or fair in 85%. Interestingly, CT findings did not correlate with clinical outcomes.

Abstract
BACKGROUND The present study aimed to evaluate the methodological quality and determine the quality of reporting of randomized controlled trials (RCTs) that assess surgical treatment for shoulder instability. METHODS A Cochrane, Pubmed, EMBASE and Trip database search was performed, including the relevant literature, regarding RCTs that report on shoulder instability published between January 1994 and January 2017. Methodological quality was assessed with a modification of the Checklist to Evaluate A Report of a Nonpharmacologic Trial (CLEAR-NPT). Points were assigned based on 18 items regarding patient characteristics, randomization, care provider characteristics, surgical details and blinding, with a total score ranging from 0 points to 18 points. Missing items were verified with the corresponding authors of the studies. Quality of reporting corresponds to the total scores including the items that were additionally provided by the authors. RESULTS We included 22 studies. Of these, nine corresponding authors provided additional information. The average methodological quality was 16.9 points (11 studies) and the average quality of reporting was 9.5 points (22 studies). Items scoring worst included information regarding the surgeon's experience, the patients' level of activity, comorbidities, analyzing according to 'intention-to-treat' principles, and blinding of care providers, participants and assessors. CONCLUSIONS RCTs reporting on shoulder instability surgery are well performed but poorly reported.

Abstract
BACKGROUND Radiographs are part of routine clinical care after radial head arthroplasty (RHA). Therefore, the aim of this diagnostic study was to assess the interobserver reliability of radiographic assessment following RHA. METHODS Anteroposterior (AP) and lateral radiographs of 24 consecutive patients who underwent press-fit bipolar RHA were evaluated with respect to 14 parameters by 14 orthopaedic surgeons specializing in the elbow: shaft loosening (AP, lateral), subcollar bone resorption, nonbridging heterotopic ossification, capitellar erosion, capitellar osteopenia, implant size, ulnohumeral joint gapping, ulnohumeral joint degeneration, proximal radio-ulnar joint congruency, stem size, stem positioning (AP, lateral) and component dissociation or polyethylene wear of the head with increased angulation. Observer agreement was evaluated using the multirater kappa (κ) measure. RESULTS Nine of 14 parameters had poor interobserver agreement [κ = 0.0 to 0.20, confidence interval (CI) = 0.0 to 0.31). Four parameters had fair agreement: subcollar bone resorption (κ = 0.27, CI = 0.12 to 0.40), capitellar erosion (κ = 0.30, CI = 0.20 to 0.40), ulnohumeral joint degeneration (κ = 0.35, CI = 0.22 to 0.51) and stem positioning in AP view (κ = 0.24, CI = 0.14 to 0.36). One parameter had moderate agreement: nonbridging heterotopic ossification (κ = 0.47, CI = 0.31 to 0.64). CONCLUSIONS The overall interobserver reliability of radiographic assessment following press-fit bipolar RHA was poor among experienced elbow surgeons. Therefore, radiographic evaluation after RHA should be interpreted with caution when making treatment decisions.

Abstract
BACKGROUND The primary aim of the present study was to review, summarize and compare the redislocation risk for collision athletes and noncollision athletes after an open Bristow-Latarjet procedure. Our secondary aim was to summarize return to sport, satisfaction, pain and complications. METHODS We conducted a systematic review in PubMed and EMBASE of articles until 1 July 2016. We included all studies describing Bristow-Latarjet like procedures as a result of glenohumeral instability, mentioning redislocation rates in collision athletes with >2 years of follow-up. We pooled the data using random-effects meta-analysis for redislocation risk-differences (RD) between collision and noncollision athletes, and assessed heterogeneity with I2 and Tau2 tests. RESULTS From 475 titles and abstracts, 11 studies were included and eight studies were meta-analyzed. The pooled RD to develop a postoperative redislocation between collision athletes and noncollision athletes was -0.00 (95% confidence interval: -0.03 to 0.03, p = 0.370). Return to sports rates were high (67-100%), and patients reported high satisfaction scores (93-100% satisfied) and low pain scores (mean visual analogue scale score of 1.6); however, postoperative complication rates varied from 0.8% to 19.2%. CONCLUSIONS Collision athletes are not more at risk for redislocation rates after an open Bristow-Latarjet procedure compared to noncollision athletes. Overall postoperative outcomes were good, although numerous complications occurred.

Abstract
This classic discusses the original publication ‘Treatment of recurrent dislocation of the shoulder’ on the Latarjet procedure. This surgical technique that has become one of the basics in shoulder-stabilising surgery, introduced by Latarjet in 1954 in the journal Lyon Chirurgical. Inspired by publications of colleagues in the field of shoulder surgery, Latarjet introduced a technique that transfers the coracoid process to the anterior glenoid rim in patients with anterior shoulder instability. Although being outrun in popularity by the Bankart repair for several decades, improved knowledge regarding long-term outcomes, surgical techniques and patient characteristics such as bone loss and participation in contact sports has led to renewed interest in the Latarjet procedure. This especially accounts for patients with significant glenohumeral bone loss or patients with a previously failed soft tissue repairs. Whereas the increase in popularity has led to many studies focussing on various aspects, the 15 basics of the initial procedure have virtually remained unchanged.

Abstract
BACKGROUND Low-intensity pulsed ultrasound (LIPUS) is frequently used to enhance or to accelerate fracture-healing, but its clinical role and effectiveness as a treatment modality remain uncertain. We performed a systematic review and meta-analysis of randomized controlled trials to determine the efficiency of LIPUS on bone-healing and/or fracture union, as well as on functional recovery. METHODS The databases of PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, CINAHL, Web of Science, and Embase were searched for trials concerning LIPUS stimulation and bone-healing or fracture repair, in any language, published from the inception of the database to January 2, 2015. Eligible studies were randomized controlled trials that enrolled patients with any type of fracture, delayed union, or nonunion and randomly assigned them to LIPUS treatment or a control group. Two reviewers independently agreed on eligibility, assessed methodological quality, and extracted outcome data. All relevant outcomes were pooled, and a meta-analysis was performed. RESULTS Twenty-four unique randomized trials were selected for analysis after the search of all databases and the inclusion of one trial by the senior author. Time to radiographic fracture union was the most common primary outcome measure evaluated. After pooling the data concerning time to radiographic healing in the combined patient population (n = 429), LIPUS treatment resulted in a mean reduction in healing time of 39.8 days (95% confidence interval, 17.7 to 62.0 days; I = 94%). The most reduction in time to radiographic union by LIPUS treatment was seen in fractures with a long natural healing tendency. Three trials evaluating the time to return to work or active duty, as a surrogate for functional recovery, were unable to demonstrate a beneficial effect of LIPUS (n = 179). Evidence from two high-quality trials implied that LIPUS enhances fracture-healing through increased bone formation in cases of delayed and/or impaired bone-healing. The prevention of delayed union or nonunion by LIPUS treatment could not be demonstrated. CONCLUSIONS LIPUS treatment effectively reduces the time to radiographic fracture union, but this does not directly result in a beneficial effect of accelerated functional recovery or the prevention of delayed union or nonunion. The increase in bone formation as a result of LIPUS treatment may provide a valuable tool in fracture repair, but it does not always lead to healing. Future studies should focus on reporting of a combination of subjective signs of clinical healing, functional recovery, and radiographic union to determine the effectiveness of LIPUS treatment in clinical fracture-healing.

Abstract
Purpose There is variability among surgeons on definitions regarding the degree of bone healing of long-bone fractures. A lack of consensus may negatively affect communication between surgeons, and lead to unintended and unwanted variability in treatment of patients suffering from abnormal healing of long-bone fractures. We aimed to identify differences between surgeons regarding their views on the degree of union of long-bone fractures. Methods We performed a survey among 114 surgeons who worked at 11 level I trauma centers and 68 level II/III hospitals in the Netherlands. We asked them to represent their institutional colleagues and answer questions regarding their views on the definition, factors influencing bone healing, clinical practice, views on scientific evidence, and the use or need of guidelines for non-union of long-bone fractures. A total of 26 trauma surgeons and 37 orthopedic surgeons responded (59%). Results Compared to trauma surgeons, more orthopedic surgeons maintain 6 months as the timeframe for classifying a fracture without healing tendencies as a non-union fracture (50 vs 70%; P = 0.019). Compared to orthopedic surgeons, trauma surgeons use the bone scan (46 vs 19%; P = 0.027) and the PET scan (50 vs 5.4%; P < 0.001) more often, and consider medication use to be a factor influencing bone healing more often (92 vs 69%; P = 0.040). Furthermore, they utilize bone marrow aspiration (35 vs 11%; P = 0.029), reaming of long bones (96 vs 70%; P = 0.010), synthetic bone substitutes (31 vs 5.4%; P = 0.012), bone morphogenetic proteins (58 vs 16%; P = 0.001), and the Diamond concept (92 vs 8.1%) more often as treatment modalities for non-union of long-bone fractures. Surgeons agreed on that intramedullary nail osteosynthesis was the treatment option supported by the highest level of evidence. 80% of the respondents feel a need for a clinical guideline on the management of long-bone non-union. Conclusion There is no consensus among surgeons on the definition, factors influencing healing, clinical practice, and scientific evidence regarding non-union of long-bone fractures. The vast majority of surgeons believe that their practice would benefit from (inter)national guidelines on this topic, and efforts should be made to reduce surgeon-to-surgeon variability in treatment recommendations and facilitate more homogenous scientific research on non-union of long-bone fractures.

Abstract
PURPOSE The purpose is to create more awareness as well as emphasize the risk of permanent nerve injury as a complication of elbow arthroscopy. METHODS Patients who underwent elbow arthroscopy complicated by permanent nerve injury were retrospectively collected. Patients were collected using two strategies: (1) by word-of-mouth throughout the Dutch Society of Shoulder and Elbow Surgery, and the Leiden University Nerve Centre, and (2) approaching two medical liability insurance companies. Medical records were reviewed to determine patient characteristics, disease history and postoperative course. Surgical records were reviewed to determine surgical details. RESULTS A total of eight patients were collected, four men and four women, ageing 21-54 years. In five out of eight patients (62.5%), the ulnar nerve was affected; in the remaining three patients (37.5%), the radial nerve was involved. Possible causes for nerve injury varied among patients, such as portal placement and the use of motorized instruments. CONCLUSIONS A case series on permanent nerve injury as a complication of elbow arthroscopy is presented. Reporting on this sequel in the literature is little, however, its risk is not to be underestimated. This study emphasizes that permanent nerve injury is a complication of elbow arthroscopy, concurrently increasing awareness and thereby possibly aiding to prevention.

Abstract
BACKGROUND Nontraumatic full-thickness rotator cuff tears are commonly initially treated conservatively. If conservative treatment fails, rotator cuff repair is a viable subsequent option. The objective of the present meta-analysis is to evaluate the shoulder-specific outcomes one year after arthroscopic or mini-open rotator cuff repair of nontraumatic rotator cuff tears. METHODS A literature search was conducted in PubMed and EMBASE within the period January 2000 to January 2017. All studies measuring the clinical outcome at 12 months after nontraumatic rotator cuff repair of full-thickness rotator cuff tears were listed. RESULTS We included 16 randomized controlled trials that met our inclusion criteria with a total of 1.221 shoulders. At 12 months after rotator cuff repair, the mean Constant score had increased 29.5 points; the mean American Shoulder and Elbow Score score increased by 38.6 points; mean Simple Shoulder Test score was 5.6 points; mean University of California Los Angeles score improved by 13.0 points; and finally, mean Visual Analogue Scale score decreased by 4.1 points. CONCLUSIONS Based on this meta-analysis, significant improvements in the shoulder-specific indices are observed 12 months after nontraumatic arthroscopic or mini-open rotator cuff repair.

Abstract
BACKGROUND The goals of this study were to evaluate the reliability of a quantitative 3-dimensional computed tomography (Q3DCT) technique for measurement of the capitellar osteochondritis dissecans (OCD) surface area, to analyze OCD distribution using a mapping technique, and to investigate associations between Q3DCT lesion quantification and demographic characteristics and/or clinical examination findings. METHODS We identified patients with capitellar OCD who presented to our orthopedic sports medicine practice between January 2001 and January 2016 and who had undergone a preoperative computed tomography scan (slice thickness ≤1.25 mm). A total of 17 patients with a median age of 15 years (range, 12-23 years) were included in this study. Three-dimensional polygon models were reconstructed after osseous structures were marked in 3 planes. Surface areas of the OCD lesion as well as the capitellum were measured. Observer agreement was assessed with the intraclass correlation coefficient (ICC). Heat maps were created to visualize OCD distribution. RESULTS Measurements of the OCD surface area showed almost perfect intraobserver agreement (ICC, 0.99; confidence interval [CI], 0.98-0.99) and interobserver agreement (ICC, 0.93; CI, 0.86-0.97). Measurements of the capitellar surface area also showed almost perfect intraobserver agreement (ICC, 0.97;CI, 0.91-0.99) and interobserver agreement (ICC, 0.86; CI, 0.46-0.96). The median OCD surface area was 101 mm2 (range, 49-217 mm2). On the basis of OCD heat mapping, the posterolateral zone of the capitellum was most frequently affected. OCDs in which the lateral wall was involved were associated with larger lesion size (P = .041), longer duration of symptoms (P = .030), and worse elbow extension (P = .013). CONCLUSIONS The ability to quantify the capitellar OCD surface area and lesion location in a reliable manner using Q3DCT and a mapping technique should be considered when detailed knowledge of lesion size and location is desired.

Abstract
BACKGROUND Various surgical treatment techniques have been developed to treat capitellar osteochondritis dissecans; however, the optimal technique remains the subject of ongoing debate. PURPOSE To evaluate clinical outcomes after arthroscopic debridement and microfracture for advanced capitellar osteochondritis dissecans. STUDY DESIGN Case series; Level of evidence, 4. METHODS Between 2008 and 2015, the authors followed 77 consecutive patients (81 elbows) who underwent arthroscopic debridement and microfracture, and loose body removal if needed, for advanced capitellar osteochondritis dissecans. Seventy-one patients (75 elbows) with a minimum follow-up of 1 year were included. The mean age was 16 years (SD, ±3.3 years; range, 11-26 years) and the mean follow-up length was 3.5 years (SD, ±1.9 years; range, 1-8.2 years). Based on CT and/or MRI results, 71 lesions were classified as unstable and 4 as stable. Clinical elbow outcome (pain, function, and social-psychological effect) was assessed using the Oxford Elbow Score (OES) at final follow-up (OES range, 0-48). Range of motion and return to sports were recorded. Multivariable linear regression analysis was performed to determine predictors of postoperative OES. RESULTS Intraoperatively, there were 3 grade 1 lesions, 2 grade 2 lesions, 10 grade 3 lesions, 1 grade 4 lesion, and 59 grade 5 lesions. The mean postoperative OES was 40.8 (SD, ±8.0). An open capitellar physis was a predictor of better elbow outcome (5.8-point increase; P = .025), as well as loose body removal/grade 4-5 lesions (6.9-point increase; P = .0020) and shorter duration of preoperative symptoms (1.4-point increase per year; P = .029). Flexion slightly improved from 134° to 139° ( P < .001); extension deficit slightly improved from 8° to 3° ( P < .001). Pronation ( P = .47) and supination did not improve ( P = .065). Thirty-seven patients (55%) returned to their primary sport at the same level, and 5 patients (7%) returned to a lower level. Seventeen patients (25%) did not return to sport due to elbow-related symptoms, and 10 patients (13%) did not return due to non-elbow-related reasons. No complications were recorded. CONCLUSION Arthroscopic debridement and microfracture for advanced capitellar osteochondritis dissecans provide good clinical results, especially in patients with open growth plate, loose body removal, and shorter duration of symptoms. However, only 62% of patients in this study returned to sports.

Abstract
PURPOSE In this anatomical cadaver study, the distance between major nerves and ligaments at risk for injury and portal sites created by trainees was measured. Trainees, inexperienced in elbow arthroscopy, have received a didactic lecture and cadaver instruction prior to portal placement. The incidence of iatrogenic injury from novice portal placement was also determined. METHODS Anterolateral, direct lateral, and anteromedial arthroscopic portals were created in ten cadavers by ten inexperienced trainees in elbow arthroscopy. After creating each portal, the trajectory of the portal was marked with a guide pin. Subsequently, the cadavers were dissected and the distances between the guide pin in the anterolateral, direct lateral, and anteromedial portals and important ligaments and nerves were measured. RESULTS The difference between the distance of the direct lateral portal and the posterior antebrachial cutaneous nerve (PABCN) (22 mm, p < 0.001), the lateral antebrachial cutaneous nerve (4.0 mm, p < 0.001), and the radial nerve (25 mm, p < 0.001) was different from the average reported distances in the literature. A difference was found between the distance of the anterolateral portal and the PABCN (32 mm, p < 0.001) compared to previous studies. Three major iatrogenic complications were observed, including: laceration of the posterior bundle of the medial ulnar collateral ligament, lateral ulnar collateral ligament midsubstance laceration, and median nerve partial laceration. CONCLUSION Surgeons increasingly consider arthroscopic treatment as an option for elbow pathology. In the present study a surgical complication rate of 30 % was found with novice portal placement during elbow arthroscopy. Furthermore, as the results from this study have indicated, accurate, precise, and safe portal placement in elbow arthroscopy is not easily achieved by didactic lecture and cadaver instruction session alone. Level of evidence V.

Abstract
Posterior shoulder dislocations are accompanied by high forces and can result in an anteromedial humeral head impression fracture called a reverse Hill-Sachs lesion. This reverse Hill-Sachs lesion can result in serious complications including posttraumatic osteoarthritis, posterior dislocations, osteonecrosis, persistent joint stiffness, and loss of shoulder function. Treatment is challenging and depends on the amount of bone loss. Several techniques have been reported to describe the surgical treatment of lesions larger than 20%. However, there is still limited evidence with regard to the optimal procedure. Favorable results have been reported by performing segmental reconstruction of the reverse Hill-Sachs lesion with bone allograft. Although the procedure of segmental reconstruction has been used in several studies, its technique has not yet been well described in detail. In this report we propose a step-by-step description of the technique how to perform a segmental reconstruction of a reverse Hill-Sachs defect.

Abstract
BACKGROUND Total elbow arthroplasty is a relatively uncommon type of arthroplasty, which has undergone several design changes in the past four decades. However, research on improvement requires knowledge of failure mechanisms that can be addressed. Therefore, we conducted a systematic review on modes of failure of total elbow arthroplasty. METHODS We conducted searches on PubMed/Medline, Embase and Cochrane databases to identify studies describing modes of failure of primary total elbow arthroplasties. The results were coupled per type of total elbow arthroplasty and individual arthroplasty models. RESULTS A total of 70 articles were included in this systematic review. 9308 individual total elbow arthroplasties were identified with 1253 revisions (13.5%). Aseptic loosening was the most prevalent reason for revision (38%), followed by deep infection (19%) and periprosthetic fractures (12%). CONCLUSION Revision rates have been found similar to a systematic review published in 2003. The revision percentage of total elbow arthroplasty for rheumatoid arthritis is significantly higher than for trauma and post-traumatic osteoarthritis. Aseptic loosening was seen less in linked implants. Infections and periprosthetic fractures did not differ between linkage design groups. Aseptic loosening remains the most frequent cause for revision of primary total elbow arthroplasty. Therefore, more research on the occurrence, progression and risk factors of aseptic loosening should be performed and lead to higher implant survival.

Abstract
BACKGROUND Compared with total shoulder arthroplasty (TSA), total shoulder surface replacement (TSSR) may offer the advantage of preservation of bone stock and shorter surgical time, possibly at the expense of glenoid component positioning and increasing lateral glenohumeral offset. We hypothesized that in patients treated for osteoarthritis with a sufficient rotator cuff, TSA and TSSR patients have comparable functional outcome, glenoid component version, and lateral glenohumeral offset. METHODS We conducted a retrospective cohort study with a minimum of 2 years of follow-up. Patients in the TSA and TSSR groups received a cemented, curved, keeled, all-poly glenoid component. A cemented anatomical humeral stem was used in TSA. TSSR involved a humeral surface replacement (all components from Tornier Inc., St Ismier, France). Patients were assessed for functional outcome. Radiographs were assessed for radiolucent lines. Glenoid component position and lateral glenohumeral offset were assessed using computed tomography images. RESULTS After 29 and 34 months of mean follow-up, respectively, TSA (n = 29) and TSSR (n = 20) groups showed similar median adjusted Constant Scores (84% vs. 88%), Oxford Shoulder Scores (44 vs. 44), Disabilities of the Arm, Shoulder and Hand scores (22 vs. 15), and Dutch Simple Shoulder Test scores (10 vs. 11). Glenoid components showed similar radiolucent line counts (median, 0 vs. 0), similar anteversion angles (mean, 0° vs. 2°), and similar preoperative to postoperative increases in lateral glenohumeral offset (mean, 4 vs. 5 mm). One intraoperative glenoid fracture occurred in the TSSR group. CONCLUSION Short-term functional and radiographic outcomes were comparable for TSA and TSSR.

Abstract
Elbow arthroscopy is a technical challenging surgical procedure because of close proximity of neurovascular structures and the limited articular working space. With the rising number of elbow arthroscopies being performed nowadays due to an increasing number of surgeons performing this procedure and a broader range of indications, a rise in complications is foreseen. With this editorial we hope to create awareness of possible complications of elbow arthroscopy, particularly nerve injuries, and provide a guideline to avoid complications during elbow arthroscopy.

Abstract
PURPOSE To determine the rate of donor-site morbidity after osteochondral autologous transplantation (OATS) for capitellar osteochondritis dissecans. METHODS A literature search was performed in PubMed/MEDLINE, Embase, and Cochrane Library to identify studies up to November 6, 2016. Criteria for inclusion were OATS for capitellar osteochondritis dissecans, reported outcomes related to donor sites, ≥10 patients, ≥1 year follow-up, and written in English. Donor-site morbidity was defined as persistent symptoms (≥1 year) or cases that required subsequent intervention. Patient and harvest characteristics were described, as well as the rate of donor-site morbidity. A random effects model was used to calculate and compare weighted group proportions. RESULTS Eleven studies including 190 patients were included. In eight studies, grafts were harvested from the femoral condyle, in three studies, from either the 5th or 6th costal-osteochondral junction. The average number of grafts was 2 (1-5); graft diameter ranged from 2.6 to 11 mm. In the knee-to-elbow group, donor-site morbidity was reported in 10 of 128 patients (7.8%), knee pain during activity (7.0%) and locking sensations (0.8%). In the rib-to-elbow group, one of 62 cases (1.6%) was complicated, a pneumothorax. The proportion in the knee-to-elbow group was 0.04 (95% CI 0.0-0.15), and the proportion in the rib-to-elbow group was 0.01 (95% CI 0.00-0.06). There were no significant differences between both harvest techniques (n.s.). CONCLUSIONS Donor-site morbidity after OATS for capitellar osteochondritis dissecans was reported in a considerable group of patients. LEVEL OF EVIDENCE Level IV, systematic review of level IV studies.
