PURPOSE OF REVIEW: The purpose of this systematic review was to assess the outcomes and complications of described cartilage restoration techniques for cartilage defects (grades I to IV) in the adolescent knee. RECENT FINDINGS: Eleven studies satisfied the inclusion criteria comprising 307 patients with a mean follow-up of 4.6 years (range 1–18.9 years). Study patients were treated with autologous chondrocyte implantation (ACI) (n = 98, mean age 16.0), microfracture (MFx) (n = 36, mean age 15.4), internal fixation (n = 71, mean age 13.1), osteochondral allograft (OCA) transplantation (n = 78, mean age 16.4), and cartillage and excision (n = 24; mean age 14.2). ACI, MFx, OCA transplantation, and internal fixation showed significant improvement in knee functionality scores. The overall complication rate was 10.6% (n = 31). OCA transplantation had the highest complication rate (26.9%; n = 21/78). SUMMARY: In summary, our review shows that ACI was the most commonly used technique. Furthermore, ACI, MFx, OCA transplantation, and internal fixation show the most promise in treating the adolescent population due to positive postoperative functional outcomes and low complication rates. However, future studies with large sample sizes, standardized outcome documentation, and long-term follow-up are required to confirm these preliminary results.

This is a technique guide for open anterior capsule reconstruction in unstable native hips due to Ehlers–Danlos syndrome. Ehlers–Danlos syndrome is a connective tissue disease that predisposes an individual to hypermobility of their soft tissues and recurrent subluxations and dislocations of their joints. This may lead to constant instability, guarding of the hip, and subsequent arthritic changes and poor quality of life. We demonstrate anterior capsule reconstruction of the hip using an Achilles tendon allograft performed through a direct anterior approach to the hip (Heuter's approach). This technique guide outlines in detail the surgical steps required to accomplish this reconstructive procedure. Furthermore, a narrated surgical video is provided that clearly depicts the anticipated result of the increased constrained provided to the hip from the anterior capsule reconstruction using an Achilles tendon allograft.

Femoroacetabular impingement (FAI) is increasingly recognized as a risk factor for early hip degeneration in young active patients. The diagnosis depends on clinical examination and proper imaging that should be able to identify abnormal and sometimes subtle morphological changes. Labral tears and cartilage lesions rarely occur without underlying bone abnormalities. Surgical approaches to treat FAI are increasing significantly worldwide, even without a clearly defined consensus of what should be accepted as the standard imaging diagnosis for FAI morphology.Hip abnormalities encompass many variations related to the shape, size, and spatial orientation of both sides of the joint and can be difficult to characterize if adequate imaging is not available.This article presents a comprehensive review about the information orthopaedic surgeons need to know from radiologists to plan the most rational approach to a painful hip resulting from a mechanical abnormality.

This chapter updates main topics in hip arthroscopy. Since chondrolabral injury has been proposed the beginning of hip osteoarthritis, other new entities play a role in the painful hip. Actually, if we want to improve long-term clinical results, we should establish better indications for surgical treatment rather than surgical technical modifications. Different options to manage chondrolabral lesions are described in this chapter, and labral reconstruction is a very popular option nowadays. Capsular management is also a hot topic that will be discussed, and its relationship with hip instability is an interesting debate. The importance of cam deformity resection and modern therapies to treat cartilage defects are other problems directly related to osteoarthritis progression in the hip.

PURPOSE OF REVIEW: We reviewed the recent literature to identify and summarize new research surrounding anterior cruciate ligament reconstruction (ACLR) with augmentation in the form of additional soft tissue procedures or biologic augmentation. Specifically, we wanted to review the failure rates of these procedures in both the primary and revision settings. METHODS: The databases Embase, PubMed, and Medline were searched on August 13, 2018, for English-language studies that reported on the use of anterior cruciate ligament reconstruction (primary and revision) in conjunction with either soft tissue or biologic augmentation. The studies were systematically screened and data abstracted in duplicates. RECENT FINDINGS: Advancements in ACLR surgery, including soft tissue augmentation, may decrease primary and revision surgery failure rates for high-risk patients. The use of biological augmentation has shown histologic and radiographic improvements. These differences, however, have failed to be statistically significant and have not resulted in clinically significant improvements in outcome. SUMMARY: The limited body of evidence has shown that the addition of soft tissue procedures may in fact lower the risk of graft re-rupture rates particularly in revision or in patients wishing to return to high-risk sports and activities. The use of biologic augmentation although promising in laboratory studies has yet to show any significant clinical results and therefore will require further studies to prove any efficacy.

PURPOSE OF REVIEW: Heterotopic ossification (HO) in hip arthroscopy is a common post-operative complication. This review was undertaken to provide an update (2014 present) on the current literature regarding HO in hip arthroscopy. RECENT FINDINGS: Risk factors for HO post-hip arthroscopy include male gender, mixed impingement, picture, and the size of CAM resection. HO prophylaxis with NSAIDs has been proven to decrease the rate of HO post-hip arthroscopy; however, there is inherent risk to long-standing NSAIDs therapy. HO post-hip arthroscopy is not uncommon as a radiological finding, but symptomatic HO post-hip arthroscopy requiring revision surgery is a rare event, at

This systematic review examined the methodological credibility and quality of reporting of all meta-analyses which have compared bone-patellar tendon-bone (BPTB) versus hamstring tendon (HT) for anterior cruciate ligament (ACL) reconstruction (ACLR). EMBASE, MEDLINE, and The Cochrane Library were systematically searched, and two reviewers independently assessed eligibility, credibility according to the Users’ Guide to medical literature, and completeness of reporting according to the preferred reporting items for systematic review and meta-analyses (PRISMA) checklist. Inter-rater agreement was quantified using Kappa, and we used Pearson’s correlation coefficient to evaluate potential associations. Seventeen meta-analyses were identified comparing BPTB versus HT for ACLR. The majority of meta-analyses were published in 2011 (5; 29 %), and North America was the most common continent of publication (6; 35 %). The three most commonly reported outcomes were stability (82 %), complications (76 %), and function (return to sport, IKDC score) (71 %). The median number of satisfactorily reported items in the Users’ Guide was three out of seven (IQR 2–4). The median number of satisfactorily reported items in PRISMA for the meta-analyses was 20 out of 27 (IQR 19–22). The credibility of the meta-analyses comparing BPTB versus HT autograft for ACLR although limited is improving with time. Earlier studies had limited methodological rigour; however, the more recent studies have shown promise in improved methodology. The study findings suggest that decisions should be made on a case-to-case basis with coordination of patient factors and preferences as well as surgeon experience on the background of the best available evidence.

Background Ultrasonography for the diagnosis of rotator cuff tears has been a topic of debate for years. The literature shows promising results for the diagnostic utility of ultrasonography for rotator cuff tears. This study assessed the effect of a surgeon-sonographer interaction on the ability of ultrasonography to predict the presence or absence of rotator cuff tears. Methods This study was a temporal cohort analysis of 775 patients to detect the diagnostic accuracy of ultrasonography at predicting a rotator cuff tear. The surgeon-sonographer interaction had three components: (1) presence of an ultrasound machine and ultrasonographer within a shoulder clinic, (2) the ultrasonographer attends shoulder operations, (3) and the ultrasonographer reviews patients preoperatively and postoperatively. Comparisons of 2 variables—presence and size of a tear—were made between the preoperative ultrasonographic findings with arthroscopic findings (gold standard). Results The diagnostic utility for the detection of rotator cuff tears by ultrasonography at the start of the study was 93% sensitive and 68% specific, and at the end of the study was 99% sensitive and 93% specific. There was an improvement in the correlation of the ability to estimate the size of rotator cuff tears from ultrasonography to surgery in both full- and partial-thickness tears. Conclusions The surgeon-sonographer interaction improved the diagnostic utility of an office-based ultrasonographer over time, particularly with respect to the overall accuracy of ultrasonography for the detection of rotator cuff tears and for the ability to predict the size of full- and partial-thickness rotator cuff tears.
