Researchers are evaluating the safety and performance of Teknimed's arthroplasty products, including CEMFIX e and GENTAFIX e bone cements and the CEMSTOP e cement restrictor, which have been used for over 20 years. These products are designed to help fix joint prostheses to bones during joint replacement surgeries, which commonly address conditions like osteoarthritis, osteonecrosis, and trauma. The study focuses on collecting real-life long-term safety and effectiveness data through a retrospective and prospective observational design. The study involves patients undergoing cemented joint arthroplasty procedures using Teknimed's bone cements and cement restrictor. It is a global, multicenter, single-arm, non-controlled study where participants will be followed according to local medical care standards. Both patients who have already had surgery with these products since January 2016 and those scheduled for such procedures are included. Participants will be monitored for up to 15 years, with primary outcomes including survival rate of the device and rates of superficial or deep postoperative infections. Data collection includes clinical follow-up visits and routine medical care assessments. The study aims to confirm the long-term safety and performance of Teknimed arthroplasty products in real-world use.

Colorectal cancer mainly affects elderly patients, with over half of new cases in France occurring in those aged 70 or older. Adjuvant chemotherapy has shown benefits in disease-free and overall survival after stage III colon cancer surgery, but its use in elderly patients remains limited. This phase III randomized study explores whether adjuvant chemotherapy improves disease-free survival in elderly patients and which chemotherapy regimen is most effective, addressing concerns about benefits for both unfit and fit elderly patients. Participants will be divided into two groups based on a multidisciplinary evaluation including a geriatrician. One group will receive fluoropyrimidine-based chemotherapy (LV5FU2 or capecitabine), and the other will receive oxaliplatin-based chemotherapy (FOLFOX4 or XELOX). Some patients may be assigned to observation only. Treatments will begin within 12 weeks after surgery. The study also evaluates specific biological markers common in elderly tumors, such as mismatch repair deficiency. During the study, participants will undergo assessments including geriatric questionnaires and medical monitoring. Researchers will track disease-free survival over three years following the last patient's enrollment. Safety and treatment effects will be monitored, with exclusion of patients expected to live less than four years or those unable to comply with follow-up. The study aims to better understand chemotherapy benefits in an elderly population after colon cancer surgery.

It is admitted that: * Bioabsorbable interference screws are frequently used for graft attachment in knee cruciate ligament reconstruction, * Bioabsorbable pins are indicated for the realignment and fixation of epiphyseal fractures, osteotomies, arthrodesis and bone grafts of toes, * Non-absorbable suture is usually used for the repair and the reinforcement of ligaments or tendons structures during surgery procedures, * Anchor devices are usually used for the repair of rotator cuff tendons and biceps tenodesis. Furthermore, resorption properties of many available devices (screws, pins) that are marketed as bioabsorbable may be different and not always very well defined. This retro-prospective study is performed to confirm the safety and performance of TEKNIMED sports surgery products in their current clinical use. Studied products include - but are not restricted to - the following TEKNIMED products: * EUROSCREW® NG * ISOFIX® * SUTUR'LINK® * A'LINK'S® * BIORESORBABLE PINS And following associated TEKNIMED instrumentation: * ACL Instrumentation * A'LINK'S® Instrumentation * STAINLESS STEEL PINS
