Advanced elbow arthroscopy: Tips and tricks.

Elbow arthroscopy can be a challenge, however, indications and benefits compared to open elbow surgery are rapidly evolving. The elbow has seemed to lag behind other joints including the knee, shoulder, ankle and the hip, both in number of cases and in widespread acceptance, as a joint amenable to arthroscopic management. This has occurred despite literature demonstrating successful utilization of arthroscopy in the management of a variety of injuries. The purpose of this review is to clarify and expand the indications for arthroscopy of the elbow in 2021. We will also offer tips and tricks to help make elbow arthroscopy more successful. Since originally publishing these guidelines in 2007, elbow arthroscopy has evolved, although the principles and progressions remain the same.

Blood Flow Restriction Training for Athletes: A Systematic Review.

BACKGROUND: Blood flow restriction (BFR) is a novel technique involving the use of a cuff/tourniquet system positioned around the proximal end of an extremity to maintain arterial flow while restricting venous return. PURPOSE: To analyze the available literature regarding the use of BFR to supplement traditional resistance training in healthy athletes. STUDY DESIGN: Systematic review. METHODS: A systematic review was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. From November to December 2018, studies that examined the effects of BFR training in athletes were identified using PubMed and OVID Medline. Reference lists from selected articles were analyzed for additional studies. The inclusion criteria for full article review were randomized studies with control groups that implemented BFR training into athletes' resistance training workouts. Case reports and review studies were excluded. The following data were extracted: patient demographics, study design, training protocol, occlusive cuff location/pressure, maximum strength improvements, muscle size measurements, markers of sports performance (eg, sprint time, agility tests, and jump measurements), and other study-specific markers (eg, electromyography, muscular torque, and muscular endurance). RESULTS: The initial search identified 237 articles. After removal of duplicates and screening of titles, abstracts, and full articles, 10 studies were identified that met the inclusion criteria. Seven of 9 (78%) studies found a significant increase in strength associated with use of BFR training as compared with control; 4 of 8 (50%) noted significant increases in muscle size associated with BFR training; and 3 of 4 (75%) reported significant improvements in sport-specific measurements in the groups that used BFR training. Occlusive cuff pressure varied across studies, from 110 to 240 mm HG. CONCLUSION: The literature appears to support that BFR can lead to improvements in strength, muscle size, and markers of sports performance in healthy athletes. Combining traditional resistance training with BFR may allow athletes to maximize athletic performance and remain in good health. Additional studies should be conducted to find an optimal occlusive pressure to maximize training improvements. REGISTRATION: CRD42019118025 (PROSPERO).

Hand Infections Associated with Systemic Conditions.

Systemic conditions are associated with higher rates of hand and upper extremity infections, leading to more severe and atypical presentations. Understanding the unique problems associated with some of the most common systemic conditions, including human immunodeficiency virus, diabetes mellitus, and rheumatoid arthritis, can assist the hand surgeon in diagnosing and treating infection in these patients. This article reviews the most common presentation of hand infections for these patients and summarizes current approaches to the management of hand infections for patients with common immunocompromising conditions.

Platelet-Rich Plasma Is an Equal Alternative to Surgery in the Treatment of Type 1 Medial Epicondylitis.

BACKGROUND: Medial epicondylitis (ME) is characterized as an overuse injury resulting in pathological alterations of the common flexor tendon at the elbow. Platelet-rich plasma (PRP) has recently become of interest in the treatment of musculoskeletal conditions as an alternative to operative management. PURPOSE: To compare the outcomes of recalcitrant type 1 ME after treatment with either PRP or surgery. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: To compare the 2 methods of treatment, we performed a retrospective review of 33 patients diagnosed with type 1 ME from 2006 to 2016 with a minimum clinical follow-up of 1 year who had failed an initial nonoperative treatment program of injections, medication, topical creams, and/or physical therapy. Overall, 15 patients were treated with a series of 2 leukocyte-rich PRP injections, and 18 patients were treated with surgery. Outcome measures included time to pain-free status, time to full range of motion (ROM), the Mayo Elbow Performance Score (MEPS), and the Oxford Elbow Score (OES). Each patient had at least 1-year follow-up. They were then contacted by telephone to determine final scores at a minimum 2-year follow-up. Unsuccessful outcomes were determined by the Nirschl grading system and failure to reach pain-free status, achieve baseline ROM, or return to previous activity. RESULTS: The mean final follow-up was 3.9 years. A statistically significant improvement was noted in both time to full ROM (42.3 days for PRP vs 96.1 days for surgery; P < .01) and time to pain-free status (56.2 days for PRP vs 108.0 days for surgery; P < .01). Successful outcomes were observed in 80% of patients treated with PRP and 94% of those treated operatively (P = .37). No significant difference was found in return-to-activity rates, overall successful outcomes, MEPS scores, or OES scores. CONCLUSION: In this case series, the use of PRP showed clinically similar outcomes to those of surgery in recalcitrant type 1 ME. PRP can be considered as an alternative to surgery in the treatment of recurrent ME, with an earlier time to full ROM and time to pain-free status compared with surgery.

Lateral Epicondylitis Debridement and Repair Using Knotless Suture Anchor.

Lateral epicondylitis, or tennis elbow, involves degeneration of the extensor carpi radialis brevis tendon and is often self-limiting, with surgery reserved for recalcitrant cases. Surgical management of tennis elbow consists primarily of either debridement alone or debridement with repair. Surgical repair is often performed using either a suture or a suture anchor. Good outcomes have been reported using standard repair methods; however, complications exist. Complications include potential loss of grip strength with debridement alone, as well as soft-tissue irritation caused by a prominent suture or knot stack after suture repair and suture anchor techniques. We describe a technique for debridement and repair of the extensor carpi radialis brevis tendon to the lateral epicondyle of the humerus using a knotless suture anchor, allowing for a watertight anatomic repair, maximum preservation of grip strength, and absence of a knot stack and resultant suture prominence.

Influence of capsular repair versus unrepaired capsulotomy on 2-year clinical outcomes after arthroscopic hip preservation surgery.

PURPOSE: The primary objective of this study was to determine whether capsular management technique influences clinical outcomes at a minimum of 2 years after arthroscopic hip preservation surgery. METHODS: A retrospective review of prospectively collected data was conducted to determine the relative influence of 2 capsular management strategies on clinical outcomes: unrepaired capsulotomy (group A) and capsular repair (group B). Four hundred three patients who had undergone arthroscopic hip preservation surgery met the inclusion criteria and had 2-year outcome data available. All patients completed 4 patient-reported outcome (PRO) questionnaires preoperatively and at a minimum of 2 years' follow-up. These included the Hip Outcome Score-Activities of Daily Living (HOS-ADL) and Hip Outcome Score-Sport-Specific Subscale (HOS-SSS) subsets, Non-Arthritic Hip Score (NAHS), and modified Harris Hip Score (mHHS). RESULTS: Group A included 235 patients and group B, 168. The mean age of all patients at final follow-up was 36.9 years. Patients in group A were significantly older (42.3 years v 29.4 years, P < .0001) and had a significantly higher body mass index (26.8 kg/m(2)v 22.9 kg/m(2), P < .0001) compared with group B. In addition, female patients were more likely than male patients to undergo capsular repair (136 female patients v 32 male patients, P < .0001). Patients in group A also showed greater chondral damage by acetabular labrum articular disruption classification (P = .0081) and reduced preoperative PROs (HOS-ADL of 60.5 v 66.0, P = .087; HOS-SSS of 37.0 v 46.4, P = .0002; NAHS of 54.6 v 62.2, P < .0001; mHHS of 58.7 v 64.4, P = .0009; and visual analog scale score of 6.3 v 5.84, P = .028). All PROs showed statistically significant improvements for both groups at a minimum follow-up of 2 years (HOS-ADL, 60.5 to 82.2 in group A and 66 to 86.1 in group B; HOS-SSS, 36.9 to 67.3 and 46.4 to 71.2, respectively; NAHS, 54.6 to 79 and 62.2 to 82.8, respectively; visual analog scale score, 6.3 to 3.1 and 5.8 to 2.9, respectively; and mHHS, 58.7 to 81 and 64.4 to 83.8, respectively; P < .0001 for all differences). Furthermore, group B showed greater overall improvements than group A for the HOS-ADL (P = .03) and NAHS (P = .03) on uncorrected univariate analysis, but significance was lost once we controlled for confounding variables. CONCLUSIONS: Arthroscopic capsular repair, used in conjunction with arthroscopic hip preservation surgery, appears to be safe and did not negatively influence clinical outcomes in this study. When confounding variables were controlled for, the use of capsular repair did not show clinically relevant superiority over the use of unrepaired capsulotomy. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
