What does total knee replacement surgery mean?
Total Knee Replacement surgery or TKR is an operative procedure where the damaged knee is replaced using an artificial knee. During the surgery, the ends of the thighbone are ejected and replaced with an artificial metal shell the edge of the leg bone is replaced with a plastic piece over a manmade metal stem.
Depending on the damaged condition of the kneecap, the undersurface will also be resurfaced with a plastic kneecap. Many designs with different materials are used in replacements. At Bharath Orthopaedics, we use advanced implants to deliver the best clinical outcomes and increase lifestyle.

Hyaluronic acid or knee shots
Hyaluronic acid is like a substance that occurs in the joints, and it acts as a lubricant as well as a shock absorber, helping the joint to work properly. Hyaluronic acid injections are also known as HA or gel injections. They are used in treating knee pain of patients with osteoarthritis or for whom other treatments have been ineffective.
How do hyaluronic acid joint injections work?
1. For a healthy joint, a fluid named hyaluronan provides lubrication. But, if are infected with osteoarthritis, there would be less supply of this fluid. Hyaluronic acid joint injections complement the joint’s hyaluronan with hyaluronic acid.
2. It is a basic procedure performed where the doctor injects hyaluronic acid directly in and around the joints’ area. The injections will depend on the specific type of usage of hyaluronan preparation, but most of the people are injected for three to five weeks.
3. If the treatment is effective, you can experience good results within days. Sometimes, the relief often lasts for several months when your doctor may recommend repetitions.
Platelet rich plasma or PRP injections
Plasma is a liquid part of the human blood mostly made of water and protein. It allows red, and white blood cells along with the platelets to move through your bloodstream. Platelets make your blood clot as they play a major role in healing.
How do PRP injections work?
To collect plasma, the surgeon takes samples of blood from your body and to separate the platelet-rich plasma from the blood he uses the machine. Then the area of your body is being treated with PRP injections. The surgeon uses a needle to inject the plasma by making the area of your body numb. PRP injections are used to treat torn tendons, muscle injuries, joint injuries, tendinitis and, arthritis.
Stem cells are special cells that act as building blocks and have the potential to distinguish the types of cells within the human body. It is a strategy to repair degenerative cartilage than implantation with a key focus of tissue on the functional replacement of cartilage and meniscus regeneration.
How does stem cell therapy work?
During the procedure, your physician will draw the blood through a peripheral vein. Then the physician will extract a sample of your bone marrow from the iliac crest which is considered as one of the most fruitful sites to harvest stem cells.
The blood samples and bone marrow samples are used to prepare an injection of growth factors from the blood and stem cells processed out of the bone marrow. This mixture is injected into the affected orthopaedic therapy targeted area to promote healing and recovery.
