Study of treatment for a painful discoid meniscus in children

Program to help recovery after knee replacement surgery
This trial tests a supportive, coach-like “embedded” program designed to help you stay engaged and ready for recovery after one knee replacement. It may be helpful if you want extra support before and after surgery to follow through with your recovery plan.
Fort Sam Houston, TexasAges 18 years+ - NCT04728542Recruiting
Observational study comparing two osteoporosis treatment approaches

MainzAges 18 years+ - NCT04236492Recruiting
Fresh cartilage graft study for large knee joint damage
This trial studies how well a fresh cartilage and bone graft works to repair large, full-thickness defects in the knee. It also looks at imaging results (pictures of the knee) to see how the repair is healing over time.
Barcelona, CataloniaAges 15–50 - NCT03908931Recruiting
Study of knee cartilage repair results
This study looks at how well certain types of knee cartilage repair work, using clinical check-ins and imaging (scans). You may be able to help researchers understand which method restores knee surface cartilage best.
Le ChesnayAges 18 years+ - NCT03328611Recruiting
Joint replacement outcomes database for degenerative joint disease
This study collects information about people with “wear-and-tear” joint disease who need joint replacement. The goal is to better understand outcomes after surgery and improve future care.
Indianapolis, IndianaAges Any age - NCT05599776Recruiting
Smart ring-guided rehab after knee replacement surgery

Tampere, PirkanmaaAges 18–70 - NCT03747146Recruiting
Enhanced recovery plan for knee replacement pain control
This study tests an “enhanced recovery” approach for people getting total knee replacement, focused on better pain control using regional anesthesia and a home pain medicine plan. It may help you recover more comfortably and follow the care plan more smoothly after surgery.
New York, New YorkAges 18–65 - NCT02503228Enrolling by invitation
Registry study of a preserved bone-cartilage graft
