This study looked at how body weight affects menstrual problems in teenage girls with eating disorders. Out of 62 girls, 21 had menstrual issues, and those with anorexia generally needed to reach a body mass index (BMI) in the 25-50 percentile range to restore normal menstruation, while those with other eating disorders needed to reach the 50-75 percentile. This research is important because it helps clinicians understand the necessary weight goals to assist in resolving menstrual disorders in young patients with eating disorders. Who this helps: Patients with eating disorders and their doctors.

Plain English
This study looked at how different exercises affect the strain and forces on the anterior cruciate ligament (ACL) during weight-bearing and non-weight-bearing activities. It found that non-weight-bearing exercises typically put more stress on the ACL compared to weight-bearing ones. Specifically, the ACL is most stressed when the knee is bent between 10 and 30 degrees and can become overloaded with improper techniques, such as squatting with knees going too far forward. Understanding these differences helps in selecting the right exercises for rehabilitation after ACL injuries. Who this helps: This benefits patients recovering from ACL surgery and their doctors.

Plain English
This study looked at how three different 6-week training programs affected the throwing speed of high school baseball players. The training groups all improved their throwing velocity: Throwers Ten increased by 1.7%, Keiser Pneumatic by 1.2%, and Plyometric by 2.0%. Importantly, all three training methods were effective, and none was shown to be better than the others, which helps players choose a training program that works for them. Who this helps: High school baseball players and their coaches.

Plain English
This study looked at how different knee rehabilitation exercises affect the loads on the anterior and posterior cruciate ligaments (ACL and PCL). Researchers found that weight-bearing exercises place less stress on these ligaments than non-weight-bearing exercises, and certain techniques—like squatting with a forward lean—can further reduce the load on the ACL. These findings help healthcare providers choose safer and more effective exercises for patients recovering from ligament injuries. Who this helps: Patients recovering from anterior and posterior cruciate ligament injuries.

Plain English
This study looked at the forces on two important knee ligaments—the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL)—during forward and side lunges. The researchers found that the force on the PCL was significantly higher during forward lunges at certain knee angles, reaching up to 765 Newtons, which suggests there's a risk to the PCL when performing these exercises. This is important because it helps doctors understand when and how to safely use lunging exercises in rehabilitation for patients recovering from knee injuries. Who this helps: Patients recovering from knee ligament injuries.

Plain English
This study looked at how different types of lunges affect the forces on the knee ligaments, specifically the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). Researchers found that lunging with a longer step caused higher forces on the PCL, reaching up to 765 newtons, compared to lunging with a shorter step. They also noted that lunges without a stride increased the forces on the PCL at certain knee angles, while the ACL only experienced significant forces in a specific lunging style. This information is important for helping doctors design safer exercise programs for patients recovering from knee injuries. Who this helps: This helps physical therapists and patients recovering from ACL and PCL injuries.

Plain English
This study looked at how well different exercises activate core muscles, comparing 8 Swiss ball exercises to 2 traditional abdominal exercises (crunch and bent-knee sit-up). The two best exercises for engaging core muscles were the roll-out and pike, with engagement levels for upper abs reaching up to 63% and for lower abs up to 55%, which was significantly higher than many other exercises that ranged between 7% to 53%. Understanding which exercises effectively activate core muscles is important for improving training and rehabilitation programs. Who this helps: This benefits patients undergoing rehabilitation and fitness enthusiasts looking to strengthen their core effectively.

Plain English
This study looked at how a 4-week conditioning program affected the throwing speed of young baseball players aged 11-15. Players who participated in the program increased their maximum throwing speed from an average of 25.1 meters per second to 26.1 meters per second, while those who didn’t do the program actually lost some speed. This is important because faster throws can give pitchers an advantage over hitters and help field players make quicker plays. Who this helps: Youth baseball players and their coaches.

Plain English
This study examined two surgical techniques to fix misalignment in the lower leg that causes knee cap dislocations. After surgery, patients who had the high tibial osteotomy technique showed much better outcomes, with significant improvements in symptoms and walking patterns compared to those who had the other technique. Specifically, the first group had more balanced gaits and less pain, highlighting that addressing both misalignment and ligament issues at the same time leads to better results. Who this helps: This helps patients with knee cap dislocations and lower leg deformities.

Plain English
The study focused on how different shoulder muscles work during common rehabilitation exercises. Researchers found that the rotator cuff muscles, particularly the infraspinatus and subscapularis, play a crucial role in shoulder movements, generating forces much stronger than the supraspinatus during certain exercises, although the supraspinatus is still the best at lifting the arm. Understanding how these muscles function together helps improve shoulder rehabilitation strategies and reduce the risk of injury, especially since certain positions can lead to impingement. Who this helps: This benefits patients recovering from shoulder injuries and the doctors who treat them.

Plain English
This study looked at four patients who developed cysts near their knees after having surgery to replace their anterior cruciate ligament (ACL) with donor tissue. The researchers found that these cysts, which resembled ganglion cysts, were successfully treated through surgery that removed the cysts and involved bone grafting. The findings are important because they suggest that these cysts may form due to incomplete integration of the donor tissue in the bone. Who this helps: These findings can assist doctors in understanding and treating complications related to ACL surgeries.

Plain English
This study looked at a new way to perform surgery for repairing the anterior cruciate ligament (ACL) using a small incision instead of traditional open surgery. It found that this endoscopic method leads to less pain and better recovery for patients, allowing them to go home the same day. Despite these benefits, the surgery's success can still vary, with many failures linked to problems with how the graft is fixed in place, especially within the first six months. Who this helps: This helps patients recovering from ACL injuries and their doctors.

Plain English
This study focused on the rehabilitation process after surgery to repair the anterior cruciate ligament (ACL) in the knee. The researchers outlined a five-phase program that emphasizes careful progression: the first three phases prioritize protection and gradual increase of activity over 12 to 48 weeks, and the final two phases aim to build strength and technique before returning to sports, which typically starts about nine months post-surgery. Following these phases helps ensure the knee heals properly and prevents re-injury, which is crucial for athletes and active individuals. Who this helps: This benefits patients recovering from ACL surgery, particularly athletes and active individuals.

Plain English
This study looked at the surgical treatment of 27 feet belonging to patients aged six months to 15 years who had a foot condition called cavovarus deformity. After following these patients for at least two years, the researchers found that over 85% of them had good results without any major complications. This is important because it shows that the surgical approach taken can effectively improve foot function in young patients with this condition. Who this helps: This helps young patients with cavovarus foot deformity and their families.

Plain English
This study looked at 186 patients who were diagnosed with typical knee sprains to see if they might actually have more serious injuries, specifically tears of the anterior cruciate ligament (ACL). The researchers found that 72% of these patients had ACL damage, with 44% having complete tears, and many also had other injuries like meniscus tears (62%). This matters because it shows that what seems like a minor knee sprain could actually be a serious issue that requires more thorough testing for proper treatment. Who this helps: This helps patients with knee injuries and their doctors by ensuring more accurate diagnoses and better treatment plans.

Plain English

It highlights three main types of surgery: simple lateral release, dynamic realignment, and tendon realignment, but emphasizes the importance of non-surgical treatments like a structured rehabilitation program. Understanding the mechanics behind the knee is crucial for successful treatment, which can help restore function and reduce pain for patients. Who this helps: This helps patients with knee problems related to patellar malalignment.

Plain English
This study looked at a 7-year-old girl who suddenly had severe left shoulder pain without any injury or overuse. Doctors found she had calcific tendinitis, which is a condition where calcium deposits form in the shoulder muscles, and after surgery to relieve the pressure in her shoulder, her pain went away completely. This is important because it highlights a rare case of this condition occurring in children, where there have been no previous reports, helping to increase understanding of shoulder issues in young patients. Who this helps: This information benefits pediatricians and orthopedic doctors treating shoulder pain in children.
