0.0 stars

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"How important is patient positioning during arthroscopic shoulder repair? A new report suggests that the use of lateral decubitus vs. beach-chair positioning does not affect the outcome of arthroscopic posterior labral repair. The findings are published in _The American Journal of Sports Medicine_. Shoulder dislocation or repetitive microtrauma to the shoulder can tear the posterior labrum, resulting in posterior shoulder instability. Although posterior instability is not as common as anterior instability, it can cause persistent pain and recurrent problems over time. Arthroscopic surgery is frequently used to repair the posterior labrum. Some physicians prefer to place patients in the lateral decubitus position for this surgery, while others prefer the beach-chair position. Each position has its own advantages, but it remains unclear whether one provides superior patient outcomes..."

"Undergoing a second operation to reconstruct a torn anterior cruciate ligament , or A-C-L, is difficult for anyone. But it could be particularly hard for those who don’t play sports after surgery. A new study shows that among patients undergoing a repeat ACL reconstruction, those who play one or more sports following their procedure report reduced knee symptoms, better knee function, and higher activity level than those who play no sports. These findings could help clinicians and patients build better pathways to recovery from ACL injury. Using a questionnaire, researchers followed up with more than 900 patients 2 years after revision ACL reconstruction. Slightly more than half of the patients were male, and patients’ average age was 26. In addition to questions regarding knee injury history and knee-specific outcomes, patients were asked whether they had participated in sports since undergoing surgery; and if so, which one—or ones..."

"Abnormal wearing of the hip joint, or femoroacetabular impingement, and dysplasia represent the two most common causes of secondary osteoarthritis of the hip joint. These pathologies are known to produce distinctive chondral flaps visible during hip arthroscopy. But the destructive mechanics behind each diagnosis differ significantly. That makes treatment planning especially difficult for patients who show signs of both impingement and dysplasia. To provide some clarity, researchers examined 95 patients demonstrating acetabular chondral flaps during arthroscopy, with the goal of correlating those findings with radiographic data. The patterns that emerged could help surgeons deliver the best possible care for patients with mixed hip pathologies. Patients exhibited one of two types of chondral flaps upon examination: “inside-out” or “outside-in”..."

"A recent study suggests that baseball players with a torn posterior labrum, the back rim on the socket that keeps the shoulder’s ball joint in place, could benefit significantly from arthroscopic surgery. Among 32 young athletes with this injury, more than 90% returned to play, with 61% returning to their previous performance level. Labral tears are common among contact and non-contact athletes alike, with different types of stresses leading to different types of tears. Among football linemen and baseball pitchers, tearing of the posterior labrum is common. Unfortunately, there’s a big disparity in the amount of research dedicated to each type of athlete. While linemen have proven able to return to sport following labral repair, the small amount of available research on baseball players suggests that pitchers won’t necessarily enjoy the same result..."

"Recent studies have shown that all-inside repair of meniscal ramp lesions can restore normal knee motion. But it has remained unclear how ramp lesion repairs affect ACL in situ forces and bony contact forces. To remedy that, researchers from the University of Pittsburgh recently used a robotic system to examine these forces in intact knees, knees with ramp lesions, and knees with ramp lesion repairs. Their findings, reported in the November issue of the American Journal of Sports Medicine, suggest that the indications for ramp lesion repair may be limited. The team looked at nine knees from human cadavers, each tested using a six-degree-of-freedom robotic system. The knees were continuously flexed from full extension to 90° under five different loads: an anterior load, an external-rotation torque, a combined anterior and compression load, and a combination of external- or internal-rotation torque and compression..."
