Spinal anesthesia with dexmedetomidine for knee surgery
This trial tests adding dexmedetomidine (a calming medication) to bupivacaine (numbing medication) injected into the spine during knee surgery. The goal is to improve pain relief and recovery after surgery.
CairoAges 18–65 - NCT07465159Recruiting

Xi'an, ShannxiAges 20–60 - NCT07124494Recruiting
Anesthesia type and recovery after knee replacement
This study compares two types of anesthesia for total knee replacement to see which helps with pain, movement, and satisfaction after surgery. If you are scheduled for a knee replacement and are willing to have a spinal or epidural anesthesia, you may be able to join.
Konya, MeramAges 18 years+ - NCT07484594Recruiting

Knee Exercises With Blood Flow Restriction for Osteoarthritis
This study compares two types of knee exercises (closed chain and open chain) with a special blood flow restriction technique to see which helps reduce pain and improve function in people with mild to moderate knee osteoarthritis.
RawalpindiAges 45–75 - NCT07402408Recruiting
Blood flow restriction training for knee osteoarthritis
This trial tests whether using a special band to limit blood flow during exercise can help reduce pain and improve movement in people with mild knee osteoarthritis. It may be an option if you have knee pain and stiffness but no other serious health conditions.
Islamabad, FederalAges 40–60 - NCT07484529Recruiting

PRP injection versus hyaluronic acid shots for knee arthritis
This trial tests whether a platelet-rich plasma (PRP) shot works better than a standard hyaluronic acid (“gel”) injection to reduce knee osteoarthritis pain. It may help people with ongoing knee pain choose the treatment that relieves symptoms more effectively.
Skokie, IllinoisAges 18–75 - NCT03519269Recruiting
Robotic versus standard knee replacement for severe knee arthritis
