Why cant human knee or hip joints be repaired by injecting something such as silicone gel into them?

,you do get a course of injections before replacement my husband has had six injections ouch.

dunno, try it and see, if it works you could seel the idea to the NHS

Since the knees and the hip joints are used so much in everyday life that the silicone gel would burn off due to the friction. Because they are more complicated than that.

---

Silicone doesn’t react well inside the human body, that’s why they came up with saline implants. Tendons and bone can’t be replaced by a gel. They do make a teflon type insert for cartilage

---

It would leak into the body

---

because even as silicone is flexible, its not STRETCHABLE enough to handle the stress from a classic knee or hip injury

You are talking about joints that take the most punishment. It just would not be feasible, nor healthy.They can do cortisone injections, but they are temporary at best.

You can have synvial replacement injections for the knee. Synvisc, Suplasyn and Arthrovisc are all similar, just made by different pharmaceutical companies. These injections are placed right into the knee joint once a week for 3 consecutive weeks. This injected substance is to replace synvial fluid in the joint and helps to lubricate the joint, thereby reducing pain and the other symptoms of osteoarthritis of the knee. Often you will be also given a cortisone injection along with the final injection to help reduce inflammation and swelling. The results of the series of injections usually lasts for 6 – 18 months. This is an excellent alternative to NSAID’s and other pain relief medication for people with mild to moderate arthritis.

My mum has arthritis in her hip. And every 6 months or so she goes to the hospital to have some kind on injection into the hip and knee joints.It helps but it disperses, and doesn’t last.Unlikely that it’s silicone though – mate!
