Evaluation and Management of the Athlete's Hip.

Hip and groin pain is common in athletes, and there are many possible underlying pathologies. It is important to describe athletic hip pathology in the context of sport-specific physiologic loads and biomechanical demands. Three distinct types of athletes with this pathology are collision athletes, hypermobility athletes, and endurance athletes.

Microbial Colonization of Capsular Traction Sutures in Hip Arthroscopic Surgery.

Background: A common practice in hip arthroscopic surgery is the utilization of capsular traction sutures that can be incorporated into the capsular repair site at the end of the procedure, potentially seeding the hip joint with colonized suture material.

Purpose: To investigate the rate of the microbial colonization of capsular traction sutures used during hip arthroscopic surgery and to identify patient-associated risk factors for this microbial colonization.

Study Design: Cross-sectional study; Level of evidence, 3.

Femoral Head Vascularity After Arthroscopic Femoral Osteochondroplasty: An In Vivo Dynamic Contrast-Enhanced MRI Study.

Background: A serious concern with surgical procedures around the hip joint is iatrogenic injury of the arterial supply to the femoral head (FH) and consequent development of FH osteonecrosis. Cam-type morphology can extend to the posterosuperior area. Understanding the limit of the posterior superior extension of the femoral osteochondroplasty is paramount to avoid underresection and residual impingement while maintaining FH vascularity.

Regular-Season Injury Rates in the National Football League After an Attenuated Preseason Due to COVID-19.

Background: The preseason is a crucial time period for professional athletes to prepare for the upcoming season. However, due to the coronavirus 2019 (COVID-19) pandemic, the 2020 National Football League (NFL) preseason was canceled. As the regular season progressed, an increased number of injuries became apparent.

Prevalence of femoroacetabular impingement in elite baseball players.

CAM-type femoroacetabular impingement continues to be an underrecognized cause of hip pain in elite athletes. Properties inherent to baseball such as throwing mechanics and hitting may enhance the risk of developing a cam deformity. Our goal is to gain an appreciation of the radiographic prevalence of cam deformities in elite baseball players.

An Increased Allograft Width for Circumferential Labral Reconstruction Better Restores Distractive Stability of the Hip: A Cadaveric Biomechanical Analysis.

Background: Questions remain about whether circumferential labral reconstruction (CLR) using an iliotibial band (ITB) allograft can effectively restore the labral suction seal of the hip.

Hypotheses: (1) CLR with an ITB allograft >6.5 mm would restore distractive stability force to that of the intact labrum.

Calculating Intraoperative Fluid Deficit to Prevent Abdominal Compartment Syndrome in Hip Arthroscopy.

Abdominal compartment syndrome (ACS) is a rare but potentially fatal complication that can occur during hip arthroscopy. This usually occurs as a result of arthroscopic fluid passing into the retroperitoneal space through the psoas tunnel. From the retroperitoneal space, the fluid can then enter the intraperitoneal space through defects in the peritoneum.

Arthroscopic Latarjet Procedure Utilizing a Latarjet With Cortical Button Fixation Performed in the Lateral Position.

Shoulder instability is a commonly seen pathology. The Latarjet procedure was first described in 1954 to address recurrent instability or patients with glenoid bone loss. Since its introduction, the procedure has been widely adopted and modified, including being performed all-arthroscopically.

Stay Ipsilateral: An Analysis of Tibial Tunnel Distance Between Cruciate Ligament Reconstruction and Posterior Meniscal Root Repair.

Purpose: To establish mean distance or identify intersection between tibial tunnels for posterior meniscal root repair in the setting of anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) reconstruction.

Methods: Twelve cadaver knees and 12 solid foam synthetic tibiae were used. ACL and PCL tunnels were drilled for single-bundle reconstruction, and both medial and lateral posterior root repair tunnels were drilled.

Proximal Overresection During Femoral Osteochondroplasty Negatively Affects the Distractive Stability of the Hip Joint: A Cadaver Study.

Background: Contact between the acetabular labrum and articular cartilage of the femoral head creates a suction seal that helps maintain stability of the femoral head in the acetabulum. A femoral osteochodroplasty may occasionally extend proximally into the femoral head, diminishing the articular surface area available for sealing contact.

Purpose: To determine whether proximal overresection decreases the rotational and distractive stability of the hip joint.

All-Arthroscopic Anatomic Length-Tension Biceps Tenodesis With Unicortical Button.

The long head of the biceps tendon is a frequent cause of persistent anterior shoulder pain. Biceps tenodesis is a popular choice for surgical management of this pathology, with myriad approach and fixation variations described. We describe an all-arthroscopic suprapectoral biceps tenodesis in the anatomic length-tension relation using a unicortical button.

Background: There is increasing concern of iatrogenic hip instability after capsulotomy during surgery. Greater emphasis is now being placed on capsular closure during surgery. There are no prospective studies that address whether capsular closure has any effect on outcomes.

Epidemiologic impact of COVID-19 on a multi-subspecialty orthopaedic practice.

The purpose of this study is to report the change in surgical case volume and composition encountered by a multi-subspecialty orthopaedic practice due to COVID-19. We reviewed electronic medical records for patients who had surgery at our institution and collected multiple variables including age and the joint that was operated on. In the post-COVID-19 period, we found a significant increase in the percentage of hip procedures, and a significant decrease in the percentage of hand/wrist procedures.

Methods: Patients who underwent hip arthroscopy from 2011-2018 were identified using Current Procedural Terminology (CPT) codes in the PearlDiver Patients Records Database (Colorado Springs, CO), which is a national database of orthopedic insurance records, including Medicare patients. The incidence of surgeries, age, and gender were all recorded.

Outside-In Capsulotomy of the Hip for Arthroscopic Pincer Resection.

Hip surgical techniques have evolved significantly, transitioning from open techniques to arthroscopic techniques. Hip arthroscopy has many advantages over open techniques, including reduced trauma to surrounding tissues, reduced risk of infection, and improved patient-reported outcome measures. Hip arthroscopic techniques are now commonly used for pathologies such as femoroacetabular impingement (FAI).
