Fundamentals of Arthroscopy Fluid Management and Strategies to Safely Improve Visualization.

Arthroscopy has become increasingly relevant to various subspecialties within the orthopaedic surgery. From a patient safety standpoint and surgical efficiency standpoint, it is critical to know the fundamental concepts of fluid management such as those related to the fluid, pressure, and flow. A satisfactory field of view during arthroscopy can be achieved with the use of gravity-dependent or automated fluid management systems.

Circumferential and Segmental Labral Reconstruction: A Systematic Review.

The purposes of this study were to synthesize, report, and compare patient-reported outcomes (PROs) between arthroscopic segmental and circumferential labral reconstruction. A systematic review was performed in February 2019 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) method. Inclusion criteria were levels I to IV evidence, articles in English, arthroscopic labral reconstruction, and PROs data.

Tobacco Use Is Associated with More Severe Adverse Outcomes Than Morbid Obesity after Aseptic Revision TKA.

The association of morbid obesity with increased revision total knee arthroplasty (rTKA) complications is potentially confounded by concurrent risk factors. This study was performed to evaluate whether morbid obesity was more strongly associated with adverse aseptic rTKA outcomes than diabetes or tobacco use history-when present as a solitary major risk factor. Demographic characteristics, surgical indications, and adverse outcomes (reoperation, revision, infection, and amputation) were compared between 270 index aseptic rTKA performed for patients with morbid obesity ( = 73), diabetes ( = 72), or tobacco use ( = 125) and 239 "healthy" controls without these risk factors at a mean 75.

Revision TKA for Instability: Poorer Outcomes after a Previous Aseptic Revision.

Instability is a common indication for early revision total knee arthroplasty (rTKA). The comparative performance of instability rTKA performed after primary TKA and instability rerevision TKA (rrTKA) performed after a previous rTKA performed for any aseptic indication have not been defined. This study was performed to determine the rate of adverse outcomes for patients undergoing aseptic instability TKA revision following a primary TKA or a previous aseptic any-cause rTKA.

Isolated Liner Revision for Total Knee Arthroplasty Instability: A Road That Should Remain Less Taken.

Isolated polyethylene liner exchange (IPLE) is infrequently selected as a treatment approach for patients with primary total knee arthroplasty (TKA) prosthetic joint instability. Potential advantages of less immediate surgical morbidity, faster recovery, and lower procedural cost need to be measured against reoperation and re-revision risk. Few published studies have directly compared IPLE with combined tibial and femoral component revision to treat patients with primary TKA instability.

Revision Total Knee Arthroplasty in Young Patients: Higher Early Reoperation and Rerevision.

Background: Revision total knee arthroplasty (rTKA) rates are increasing in younger patients. Few studies have assessed outcomes of initial aseptic rTKA performed for younger patients compared with traditional-aged patients.

Methods: A detailed medical record review was performed to identify patient demographics, medical comorbidities, surgical rTKA indications, timing from index TKA to rTKA, subsequent reoperation rates, component rerevision rates, and salvage procedures for 147 young patients (158 knees) aged 55 years and younger and for a traditional older cohort of 276 patients (300 knees) between 60 and 75 years.

Achieving a Perfectly Spherical Femoroplasty: Pearls, Pitfalls, and Optimal Surgical Technique.

Femoroacetabular impingement describes a pathologic interaction between the bony femoral head/neck junction and acetabulum. Cam-type femoroacetabular impingement results from an aspherical femoral head architecture, which increases early contact along the acetabular surface during hip range of motion. Errant arthroscopic femoroplasty recently has been discussed within the literature to describe a preventable etiology of failed hip arthroscopy, most notably cam over- and under-resection.

Return to Sport and Athletic Function in an Active Population After Primary Arthroscopic Labral Reconstruction of the Hip.

Background: Labral reconstruction has been advocated as an alternative to debridement for the treatment of irreparable labral tears, showing favorable short-term results. However, literature is scarce regarding outcomes and return to sport in the nonelite athletic population.

Purpose: To report minimum 1-year clinical outcomes and the rate of return to sport in athletic patients who underwent primary hip arthroscopy with labral reconstruction in the setting of femoroacetabular impingement syndrome and irreparable labral tears.

Hip Labral Augmentation With Tibialis Anterior Tendon Allograft Using the Knotless Pull-Through Technique.

The importance of the labrum in the biomechanics of the hip joint is well documented. Labral tears are the most common pathology in patients undergoing hip arthroscopy and therefore appropriate labral management is vital. Labral preservation has been advocated as a superior alternative to labral excision in terms of clinical outcomes.

An Intact Ligamentum Teres Predicts a Superior Prognosis in Patients With Borderline Dysplasia: A Matched-Pair Controlled Study With Minimum 5-Year Outcomes After Hip Arthroscopic Surgery.

Background: Hip arthroscopic surgery in patients with borderline dysplasia continues to be controversial. In addition, it has been suggested that ligamentum teres (LT) tears may lead to inferior short-term patient-reported outcomes (PROs) when compared with a match-controlled group.

Purposes: (1) To report minimum 5-year PROs in patients with borderline dysplasia and LT tears who underwent hip arthroscopic surgery and (2) to compare these PROs to those of a matched-pair control group of patients with borderline dysplastic hips without LT tears.

Arthroscopic Ligamentum Teres Reconstruction Using Anterior Tibialis Allograft and the Tension-Slide Technique.

Once perceived to be a vestigial structure, the ligamentum teres (LT) is now increasingly understood to be critical to providing stability in the adult hip. Surgical treatment with arthroscopic debridement is usually the procedure of choice to treat LT tears. However, reconstruction is a possible alternative in select cases.

Platelet-Rich Plasma Versus Surgery for the Management of Recalcitrant Greater Trochanteric Pain Syndrome: A Systematic Review.

Purpose: To perform a systematic review of the outcomes of platelet-rich plasma (PRP) injections as an in-office procedure versus surgical treatment for recalcitrant greater trochanteric pain syndrome (GTPS).

Methods: The MEDLINE and Embase databases were searched in June 2019 following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Clinical studies on patients with recalcitrant GTPS treated with PRP or surgery were included.

Hip-Spine Syndrome: The Diagnostic Utility of Guided Intra-articular Hip Injections.

Overlapping symptoms between hip and lumbar spine pathologies complicate diagnoses and treatments. The purpose of this study was to determine the utility of guided intra-articular hip injection in identifying the pain source in hip-spine syndrome. A search of PubMed and Cochrane databases yielded 9 studies.

Radiographic and Demographic Factors Can Predict the Need for Primary Labral Reconstruction in Hip Arthroscopic Surgery: A Predictive Model Using 1398 Hips.

Background: Labral tears are the most common findings in patients with symptomatic femoroacetabular impingement (FAI). The restoration of labral function is critical, and labral reconstruction has been proposed as an alternative for irreparable tears.

Purpose: To compare preoperative radiographic measurements and demographics of patients who underwent primary arthroscopic labral reconstruction versus primary labral repair and to identify factors that are predictive of the need for reconstruction.

Microfracture in Hip Arthroscopy. Keep It Simple!

Despite all the advances in hip arthroscopy, microfracture is still the workhorse for treating focal and full-thickness cartilage lesions. The success of this treatment is owed to its reliability and simplicity. Given the structure of the hip joint, however, there are challenges to this procedure using a conventional microfracture pick.

Do Not Take for Granted! The Art of Elevating the Capsule in Hip Arthroscopy: A Stepwise Approach.

Different techniques have been described to close or plicate the capsule. To perform these procedures, however, the capsule must be preserved, a consideration unfortunately often overlooked. This Technical Note describes in a stepwise manner the initial capsular management necessary to preserve the capsule for further procedures such as closure or plication.

Direct anterior approach versus posterior approach in primary total hip replacement: comparison of minimum 2-year outcomes.

Introduction: The direct anterior approach (DAA) has gained popularity in recent years for total hip arthroplasty (THA). Several authors reported significantly better early outcomes when compared to the posterior approach (PA). Nevertheless, controversy exists regarding longer-term benefits of the DAA.

Forget the Greater Trochanter! Hip Joint Access With the 12 O'clock Portal in Hip Arthroscopy.

Most surgeons rely on the greater trochanter as the reference point to establish the anterolateral portal. Nevertheless, we believe that the anterosuperior iliac spine is a more reliable landmark. Unlike the greater trochanter, it is unaffected by leg rotation and is more easily identified by palpation.

Hip labral reconstruction: consensus study on indications, graft type and technique among high-volume surgeons.

To survey high-volume hip arthroscopists regarding their current indications for labral reconstruction, graft preference and technique. In May 2018, a cross-sectional based survey was conducted on high-volume hip arthroscopists. A high-volume surgeon was defined as an orthopaedist who had case experience ranging from 50 to 5000 hip arthroscopies performed annually.

The Modified Resisted Internal Rotation Test for Detection of Gluteal Tendon Tears.

Greater trochanteric pain syndrome (GTPS) has received increasing attention in recent years. Most patients with GTPS present with trochanteric bursitis and respond to nonoperative treatment. However, a subset of patients may have persistent lateral hip pain or recalcitrant GTPS resulting from an undiagnosed gluteal tendon tear.
