Randomized Controlled Trial
Early Viscosupplementation After Anterior Cruciate Ligament Reconstruction: A Randomized Controlled Trial.
Hyaluronic acid (HA) has been widely used to treat osteoarthritis given its biological and mechanical properties. Because HA is an "intra-articular" treatment approach that affects the joints, it could be used in the management of acute conditions, such as during the early postsurgical phase, to reduce inflammatory stress and improve articular function. ⋯ NCT02630407 (ClinicalTrials.gov identifier).

Symptomatic labral tears are common in patients with acetabular dysplasia; however, optimal treatment of the labrum remains controversial. ⋯ Patients undergoing combined arthroscopic labral refixation and PAO were older and had increased acetabular anteversion versus patients undergoing PAO alone. Combined arthroscopic labral refixation and PAO was safe, did not affect PAO operative time or radiographic correction achievement, and may benefit clinical outcomes in this patient subset.

Symptomatic global retroversion of the acetabulum, as diagnosed on plain radiographs of the pelvis, has traditionally been treated with reverse periacetabular osteotomy, which improves posterior undercoverage and eliminates the anterior pincer lesion. There is a paucity of literature on hip arthroscopy in this group, secondary to theoretical concern of iatrogenic dysplasia, subsequent instability, and arthritis. ⋯ This study demonstrates that hip arthroscopy can successfully treat femoroacetabular impingement associated with a globally retroverted acetabulum at a minimum 2-year follow-up. Survivorship was 99% at 2 years, with 1 patient requiring further surgery in the form of hip arthroplasty. There was no noted progression of Tönnis grade at final follow-up. The procedure was extremely safe, with a minor complication rate of 3.6%.

A diagnosis of lower leg deep posterior chronic exertional compartment syndrome (dp-CECS) is made by a dynamic pressure measurement. The insertion of a pressure catheter is guided by anatomic landmarks (freehand) or by ultrasound. The catheter tip is ideally positioned in the tibialis posterior muscle (TP). The accuracy of in vivo catheter placement using lower leg magnetic resonance imaging (MRI) in healthy patients suspected of having dp-CECS has never been studied. ⋯ Palpation-guided placement of catheters for TP pressure measurements is suboptimal in more than half of the patients with suspected lower leg dp-CECS. Optimizing the pressure catheter tip positioning technique may improve diagnostic accuracy in dp-CECS.

No previous studies have described the incidence of acromioclavicular (AC) joint injuries in a large sample of National Collegiate Athletic Association (NCAA) student-athletes. Such data are needed to understand the injury prevalence, mechanisms of injury, and recovery patterns in NCAA student-athletes. ⋯ The highest rates of AC joint sprains occurred in men's football, ice hockey, and wrestling as well as women's ice hockey. Most AC joint sprains across all sports occurred because of a contact mechanism, particularly from player-player contact. Further research into the specific activities and exposures at the time of injury may lend a better understanding of the causation of these injuries and lead to appropriate interventions to decrease their incidence and severity.
