January 2025
Article Synopsis
- The study investigates the outcomes of arthroscopic lateral ligament repair for chronic lateral ankle instability (CLAI) in patients with and without an os subfibulare, a bone fragment that can complicate treatment; 33 patients (39 ankles) were tracked for over 2 years post-surgery.* -
- Results indicated significant improvements in both groups for overall foot function and related symptoms, as measured by the Japanese Society for Surgery of the Foot (JSSF) scale and the Self-administered Foot Evaluation Questionnaire (SAFE-Q), with no major differences between the ossicle and non-ossicle groups.* -
- In the group with os subfibulare, only 14.3% achieved bone union post-surgery,
Article Synopsis
- Diagnosing chronic lateral ankle instability (CLAI) involves assessing medical history, physical exams, and imaging techniques, but the best method is still debated.
- Recent advancements include the anterior drawer test for ligament insufficiency and the use of ultrasonography, which is less invasive and provides dynamic assessments.
- Combining physical exams with imaging, like MRI, is crucial for accurate CLAI diagnosis, and future studies should aim to standardize testing methods.
Ramp lesions of the medial meniscus are associated with greater preoperative anterior knee laxity in anterior cruciate ligament injury.

Purpose: To assess the incidence of ramp lesions in anterior cruciate ligament (ACL) injuries and to compare preoperative knee laxity between the patients with and without ramp lesions by using an electromagnetic measurement system (EMS).
Methods: Two hundred six patients who underwent primary ACL reconstruction with preoperative EMS measurements were retrospectively enrolled in the present study. The diagnoses of the ramp lesions were made by arthroscopic inspections.
Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required.

- Knee osteoarthritis (KOA) causes joint pain and disabilities, with procedures like OWHTO and OWDTO used to relieve symptoms and delay progression, but the impact on quadriceps strength post-surgery is not well understood.
- A study of 120 knees examined quadriceps strength before and after these surgeries, finding that strength increased significantly at 12 months post-OWHTO, while improvements in OWDTO were not statistically significant.
- The study concludes that quadriceps strength improves after both procedures, especially OWHTO, and suggests further research on its relationship with recovery outcomes and rehabilitation strategies.
