Background: Surgical repair of full thickness biceps tears has demonstrated adequate outcomes in short and mid-term studies. However, data on the long-term outcomes of full thickness distal biceps injuries and their treatment are currently lacking. Purpose/Hypothesis: The purpose of this study was to report on patient demographics, injury characteristics, and long-term outcomes for patients with full-thickness distal biceps tears. It was hypothesized that complete distal biceps tears managed operatively would demonstrate robust clinical success at long-term follow-up. Study Design: Case series; Level of evidence, 4. Methods: Patients with magnetic resonance imaging–confirmed, complete distal biceps tendon rupture sustained between 1996 and 2016 were identified. Patients were cross-referenced with a regional geographic database. Results: A total of 66 patients (3 female, 63 male) with a median age of 50.8 years (IQR, 41.5-60.4) and a median clinical follow-up of 14.7 years (IQR, 9.6-17.9 years) were included. Patients who sustained a full-thickness distal biceps tendon tear were likely to be in their early 50s, male, right-hand dominant, current/former smokers, and laborers with a history of traumatic injury during an intentional movement. Most of these patients had pain and supination weakness but no loss of range of motion. All included tears were treated operatively. At final follow-up, patients maintained a majority of near-normal range of motion (median total arc of flexion/extension 140° and supination/pronation 80°), excellent elbow flexion strength (91% of patients had full strength), and adequate elbow supination strength (76% of patients had full strength). The overall complication rate was 24%, with 16 out of 66 patients experiencing some type of complication between infection, rerupture, heterotopic ossification, reoperation, and nerve complications. Overall return to work was 98%, and 85% of those who returned to work did so without restrictions. Conclusion: Complete tears of the distal biceps were most common in patients 50 years of age, male sex, right-hand dominant, and current/former smokers. The most common profession was laborer, and injuries were primarily traumatic in nature during intentional activity. Patients managed operatively demonstrated high rates of success at long-term follow-up with respect to elbow function and clinical outcomes.

Background There is a paucity of literature analyzing data for return to sport (RTS) and return to work (RTW) in the setting of direct anterior approach (DAA) total hip arthroplasty (THA). Objective The aims of this systematic review are to identify existing literature and to aggregate rates of RTS/RTW following DAA THA in a meta-analysis. Methods A query of major databases yielded 1819 initial studies. A random-effects model approach was implemented for meta-analysis. Moderator effects were assessed with respect to patient demographics and functional outcomes. Results Five studies reporting RTS after DAA THA were identified, representing a total of 204 patients with a mean age of 60.2±7.5 years and mean follow up of 31.8±9.5 months. Pooled rate of RTS was 76%(95% confidence interval [CI], 63%-86%;range 58%-100%). Pooled rate of return to the same sport was 77%(95%CI, 64%-86%;range of 62%-100%). Pooled rate of RTS to the same intensity was 58%(95%CI, 48%-68%;range of 41%-68%). Meta-regression demonstrated no significant correlations between independent variables and RTS characteristics. Three studies reported RTW rates. Rates of RTW within 3-months were 30%, 45%, and 60%. One study reported rate of RTW of 79% at 6-months and 87% at 12-months. One study demonstrated a mean time to RTW of 38±24.8 days. Conclusion Pooled rate of RTS is satisfactory following DAA THA and are comparable to rates of RTS aggregated without delineating surgical approach. Data supporting RTW rates following DAA THA limited, and thus more primary studies are needed to establish if this approach confers an advantage of faster RTS/RTW.

Abstract As the prevalence of hip arthroscopy increases, hip capsular defects are increasingly recognized as a source of recurrent symptoms in the young athletic hip. The hip capsule is of substantial importance in providing joint stability and normal biomechanics. Several recent studies have demonstrated that capsular closure at the time of primary hip arthroscopy improves both short‐ and long‐term patient‐reported outcomes, revision rates, and conversion to arthroplasty. Similarly, capsular insufficiency has been shown to be a source of recurrent pain and microinstability. Arthroscopic hip capsular management in the setting of chronic defects can be technically challenging, and far medial defects along the iliopsoas bursa are historically difficult to successfully repair because of challenging access and common lack of a proximal cuff of tissue for repair. We present an effective method for arthroscopic management of far medial hip capsular defects that consistently allows for reproducible capsular repair even in the absence of proximal capsular tissue.

Abstract Radial meniscal tears can be challenging to address and require advanced arthroscopic techniques for satisfactory repair. When radial tears occur in older patients, the surgeon often encounters suboptimal tissue integrity that presents its own challenges. Incorporating ripstop sutures in tie‐grip repair constructs for radial tears has been documented in the literature with favorable biomechanical properties. This Technical Note and accompanying video present a reproducible method for incorporating tie‐grip and mobile ripstop stitches to fortify traditional meniscal repair configurations for radial tears. This technique augments the biomechanical strength of repair and may prove useful in poor tissue quality and areas of small focal deficiency, especially in scenarios with repairable but degenerative meniscal tissue. This is particularly relevant considering many repairs fail due to pull‐through of sutures within the meniscal tissue. Technique Video video See video under supplementary data.

Objectives: Hip arthroscopy is rapidly advancing, with literature increasingly reporting positive outcomes at short- and mid-term follow-up; however, available long-term data remains limited. The purpose of this study is to evaluate long-term outcomes of primary hip arthroscopy at minimum 10-year follow-up at two academic centers by describing patient-reported outcomes (PROs) and determining reoperation, revision, and total hip arthroplasty (THA) rates. Methods: Primary hip arthroscopies performed between January 1988 and April 2013 at 2 academic centers were evaluated for postoperative PROs including Visual Analogue Scale (VAS), Tegner Activity Scale score, Hip Outcome Score Activities of Daily Living and Sport Scale (HOS-ADL/HOS-SS), modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), 12-item International Hip Outcome Tool (iHOT-12), surgery satisfaction, function, and reoperations. Results: Two-hundred ninety-four primary hip arthroscopies with a mean age of 40±14 years; 66% female; and a mean body mass index (BMI) of 27±6 kg/m 2 were followed for mean 12±3 years (range: 10-24). Labral debridement and repair were performed in 41% and 59% of patients, respectively. All patients underwent interportal capsulotomy and 2% underwent T-capsulotomy. Eleven percent of patients underwent capsular repair. At final follow-up, patients reported mean VAS at rest of 2±2, with use of 3±3, iHOT-12 of 68±27, NAHS of 81±18, mHHS of 79±17, HOS-ADL of 82±19, and HOS-SS of 74±25. Mean surgical satisfaction was 8.4±2.4 (Table 1). Sixty-five hips (23%) underwent THA and 33 (11%) underwent revision arthroscopy (Table 2). Risk factors for THA included older age (p<0.001), higher BMI (p<0.001), lower lateral center-edge angle (p=0.039), larger alpha angle (p=0.001), higher Tönnis grade (p=0.011), labral debridement (p=0.004), and capsular nonrepair (p=0.030). Patients undergoing combined labral and capsular repair demonstrated a THA conversion rate of 3% compared to 31% for patients undergoing combined labral debridement and capsular nonrepair (p=0.006) (Table 3). Labral repair trended towards increased 10-year THA-free survival (84% vs. 77%, p=0.085) while capsular repair demonstrated significantly increased 10-year THA-free survival (97% vs 79%, p=0.032) (Figure 1). Conclusions: At minimum 10-year follow-up, patients undergoing primary hip arthroscopy demonstrated high rates of satisfaction and acceptable outcome scores. In total, 11% of patients underwent revision hip arthroscopic surgery with a THA conversion rate of 23%. Conversion to THA was associated with patient factors including older age and higher Tönnis grade as well as potentially modifiable surgical factors including labral debridement and capsular nonrepair.

Objectives: Meniscal allograft transplantation (MAT) is an accepted and effective treatment option in the context of unsalvageable menisci, particularly in young and active patients. It has been shown to reduce pain and improve knee function in previously symptomatic patients. However, there is still limited knowledge about the long-term survival rates of allografts, the durability of clinical results, and the influence of patient-specific parameters, such as leg alignment, tibial slope, and preoperative International Cartilage Regeneration & Joint Preservation Society (ICRS) grade. The purpose of this study was to determine (1) the long-term clinical success rate after MAT with bony fixation in a large, single-center cohort of consecutive patients, and (2) if patient-specific and procedural variables influence the clinical, anatomic, and subjective outcomes and risk of failure. Methods: Data on 185 consecutive knees undergoing MAT in a single institution were prospectively collected and screened for inclusion in this study. The minimum follow-up time was 2 years. Radiographic variables (International Cartilage Regeneration & Joint Preservation Society [ICRS] grade and Kellgren and Lawrence grade) were assessed preoperatively and at follow-up. Subjective patient-reported outcome measures (PROMs), Lysholm score, Knee Disability and Osteoarthritis Outcome Score (KOOS) including subscores, International Knee Documentation Committee (IKDC) score, and visual analog score (VAS) were collected preoperatively and at follow-up. Clinical failure was defined as revision surgery due to graft failure or conversion to total knee arthroplasty (TKA). Anatomic failure was considered a tear covering >20% of the allograft, any peripheral tear, and unstable peripheral fixation leading to dislocation of the graft. Subjective failure was defined as Lysholm score ≤65. Preoperative tibial slope and leg alignment were assessed. Survival analyses were performed utilizing the Kaplan-Meier estimate. Univariate and multivariate analyses were performed to determine risk factors for clinical and anatomic failure. Results: A total of 157 knees met inclusion criteria (Table 1). After a mean follow-up time of 7 ± 3.5 years, 127 (80.9%) knees were free of clinical, anatomic, and subjective failure. Fourteen (8.9%) knees experienced clinical failure, 26 (16.6%) knees were identified as anatomic failure, and 13 patients (8.3%) suffered from subjective failure with a reported Lysholm score of ≤65 at a mean follow-up of 7 years. Concurrent osteochondral allograft transplantation was identified as a predictor of both clinical (HR 4.55; 95% CI 1.46-14.17; p=0.009) and anatomic failure (HR 3.05; 95% CI 1.34-6.92; p=0.008). Cartilage damage of ICRS grade 3 or 4 of the index compartment conveyed an increased risk for clinical (HR 3.41; 95% CI 1.05-11.01; p=0.04) and anatomic failure (HR 3.04; 95% CI 1.31-7.11; p=0.01) (Table 2). There were no differences in outcomes between medial and lateral MAT. High-grade cartilage damage (defined as ICRS grades 3 and 4) preoperatively (HR 10.67; 95% CI 1.037-109.768; p=0.046), patients age over 25 (HR 5.44; 95% CI 0.120-246.070; p=0.384), and a body mass index >30 (HR 2.24; 95% CI 0.748-6.705; p=0.149) were associated with subjective failure. Considering the entire study population, PROMs including KOOS and IKDC were significantly improved at final follow-up compared to preoperative scores across all measurements (p<0.005). Conclusions: MAT showed good-to-excellent clinical results at a mean follow-up of 7 years. Low ICRS lesion grade was associated with a higher clinical and anatomic survival rate. Patients with concurrent osteochondral allograft transplantation are at higher risk of clinical and anatomic failure, but still report significantly improved PROMs. These results suggest MAT has a lasting beneficial effect both as in isolation and in complex cases with one or more concurrent procedures.

Abstract Unstable osteochondritis dissecans lesions of the medial femoral condyle have classically been treated with open reduction and fixation under direct visualization through an open arthrotomy. Given the value of avoiding open arthrotomies, we present an arthroscopic approach for lesion elevation, debridement, and fixation. The lesion is first elevated using an arthroscopic elevator, leaving a laterally based osseous hinge. Once elevated, fibrous debris is debrided from the base of the lesion. Subsequently, the fragment is reduced, and percutaneous transpatellar instrumentation is used for fixation. The use of this technique allows for excellent mobilization, debridement, and fixation of the osteochondritis dissecans lesion while minimizing violation of periarticular soft tissues.

Case: A 20-year-old woman presented with a unipolar, 1.8 × 1.8-cm osteochondral defect of the left acetabulum. Osteochondral allograft transplantation was performed using a medial tibial plateau allograft resulting in excellent clinical outcomes across 4 different outcome scores and maintenance of the joint space at 4.3 years postoperatively. Conclusion: Although previous literature has demonstrated long-term clinical success of osteochondral allograft transplantation in knee, excellent clinical outcomes can also be obtained in the hip. Thus, osteochondral allograft transplantation may be a viable treatment option for adolescents and young adults with concomitant cartilage and subchondral bone hip defects.

Abstract Shoulder arthroscopy is one of the most common orthopaedic procedures. Since its introduction in the 1970s, significant advances have been made in surgical techniques and instrumentation. Shoulder arthroscopy is often performed in either the beach‐chair or lateral decubitus position, and each positioning technique has its own benefits. In this work, we will describe the history of lateral decubitus positioning for shoulder arthroscopy. We outline a detailed guide for safe and consistent lateral decubitus positioning, and key steps of lateral decubitus positioning will be emphasized. Pearls, pitfalls, advantages, and disadvantages of this positioning technique will also be discussed. With appropriate technique, lateral decubitus positioning is safe and effective for arthroscopic treatment of various shoulder pathologies. Technique Video video See video under supplementary data.

Background: Lateral meniscal oblique radial tears (LMORTs) are the most common type of lateral meniscal tears and occur concomitantly with anterior cruciate ligament (ACL) tears in up to 12% of cases. Four types of LMORTs have been classified in the literature based on proximity to the meniscal root and extent of the tear. Type 1 and 2 LMORTs represent partial and complete posterior root tears less than 10 mm from the root insertion. Type 3 and 4 LMORTs are partial and complete posterior radial meniscus tears greater than 10 mm from the root insertion. Indications: Type 3 and 4 LMORTs can and should be addressed with an all-inside side-to-side repair at the time of ACL reconstruction. LMORTs that are not repaired at the time of ACL reconstruction can contribute to persistent instability and meniscal extrusion. Technique Description: Diagnostic arthroscopy is performed to evaluate the posterior aspects of both the medial and lateral meniscus. The medial leaflet is commonly flipped into the notch and scarred to ACL remnant. After identifying and isolating the medial leaflet, an arthroscopic suture passer is used to pass a suture from inferior to superior through the medial leaflet. A second suture is passed from inferior to superior through the lateral leaflet. This is used to shuttle the suture pass through the medial leaflet to the bottom of the meniscus, where it can be tied in a horizontal mattress fashion. The sutures are tied down with aide of an arthroscopic knot pusher. A second set of sutures is passed and used to shuttle a second suture that would be tied posterior to the first suture, again in a horizontal mattress fashion. This allows reduction of the fragments in apposition across the tear. Postoperatively, patients are allowed range of motion from 0° to 90° and to toe touch weightbearing for the first 4 weeks. Patients are advanced to weightbearing as tolerated at 5 weeks. Typical return to sport ranges from 6 to 9 months postoperatively. Results: Results have been published for 2-year outcomes of type 3 and 4 LMORT repairs and have demonstrated persistent improved patient-reported outcomes as well as healing rates that are greater than 80% and in some series approach nearly 100%. Discussion/Conclusion: Arthroscopic all-inside side-to-side surgical repair is a durable and reliable treatment option for patients presenting for ACL reconstruction with concomitant type 3 or 4 LMORT.
