My rheumatologist told me my knee is bone on bone. Is that a reason for total knee replacement?

My rheumatologist told me my knee is bone on bone. Is that a reason for total knee replacement?

Yes: bone on bone means that the cartilage has worn away and the internal hydrolics that allow separation of bones that form the knee are gone. an off loading brace will control the symptoms by not allowing the bone on bone to occur, but if you are that symptomatic and have no serious medical problems that would threaten your health, replacement is the best technology at that stage. ...Read more

My orthopedic Dr said the cartilage is gone in my knee. Also have bone spurs. Will PT help? He said eventually I'll need a total knee replacement.

My orthopedic Dr said the cartilage is gone in my knee. Also have bone spurs. Will PT help? He said eventually I'll  need a total knee replacement.

Yes: yes physical therapy is important. The better your muscle tone is the better your knee will be. If eventually you need to have a total knee replacement you will have a much better outcome with good muscle tone. Do not avoid physical therapy. Please have your physician send you to physical therapy. ...Read more

My ortho Dr said I have no cartilage in my knee with severe arthritis. He suggested PT to begin with. Then possible knee replacement. Will PT help?

Varies : It varies somewhat, but in general PT does not do a lot for end stage arthritis in the knee. The main good non surgical alternative is visco-supplementation, which is the injection of lubricating fluid into the knee to supply sime "cushion"; synvisc (hylan g-f 20) is one example of this. ...Read more

My mother has pateller cluch after total knee replacement, which is better for her-either othroscopy or open excission?

My mother has pateller cluch after total knee replacement, which is better for her-either othroscopy or open excission?

Either can work: Patellar clunk syndrome occurs when fibrous scar tissue grows around the patellar implant in posterior stabilized total knee implants. The scar tissue catches in the recessed box of the femoral implant when the knee flexes and pops or clunks when the knee extends. It can be painful and treated with either arthroscopic or open removal with great success. ...Read more

My mom weight is 86 kgs. Her knee xray shows no gaps between two bones in both knees doctors suggested for knee replacement. At 48 yrs age is it good.

Degree of pain: The only real reason to replace the knee joint is intractable pain uncontrolled with safe, non habituating medication, joint injection and other conservative measures.

No cartilage in knees, bone on bone, and knee caps are misaligned. Do i need total knee replacement surgery?

No cartilage in knees, bone on bone, and knee caps are misaligned. Do i need total knee replacement surgery?

Total knee surgery: Possibly, however the decision to perform a total knee replacement doesn't just depend on xray findings of "bone on bone" arthritis. Many non-surgical options are available to improve symptoms of knee arthritis in an effort to delay surgery such as: medications, injections, braces, activity modification, and physical therapy. ...Read more

Would total knee replacement , elimminate my grade 3 chondromacia?

Would total knee replacement , elimminate my grade 3 chondromacia?

Yes: A total knee resurfaces the parts of the knee that rub together. Instead of having worn out cartilage (chondromalacia) or bone rubbing together, you would have artificial surfaces of metal and polyethylene rubbing together. As these materials have no nerve endings, there is no pain created where they are in contact. The worn areas of cartilage are replaced. ...Read more

My active sister broke her hip 2mo ago. She had hip replacement, infection, replacement of artif hip with spacer, then removal of spacer. What next?

Try to do again: Minimum of six weeks of IV antibiotic therapy. Once off antibiotics, blood tests to look for signs of infection returning. If incision and bloodwork good then attempt to put another hip repalcement back in. Cultures at time of surgery and tests during surgery possibly may show continued infection and ultimate replacement may need to be delayed further until all signs of infection are gone. ...Read more

Kneecap tracking.: It may be related to quad muscle shutdown, following surgery, which can alter the tracking of your kneecap, and give you the "popping" that you're feeling. Check with your surgeon to see if that's the case. If so, it should get better with physical therapy. ...Read more

My 67 years old mom has onfh (osteonecrosis of the femeral head) on both hip joints, what's success rate on surgery to replace total hip in her age?

Very high: Rates depend on what you are defining as success. Hip replacement is more than 90% successful in reducing or eliminating pain. Depending on your mother's activity level and desired activities, some changes may need to be made but her orthopedic surgeon could talk to her about this before the surgery and be more specific. ...Read more
