Cartilage Regeneration
Autologous chondrocyte implantation (ACI), for example, involves taking a sample of your cartilage cells, growing them in a lab and then surgically replanting them in your knee. It's not for everyone, but young people and athletes affected by cartilage loss may be candidates.
Genicular nerve radiofrequency ablation is a minimally invasive treatment for knee pain due to osteoarthritis of the knee, and can significantly reduce pain, especially for adults who are 50 and older.
A total knee replacement is the most common knee replacement surgeries for bone-on-bone arthritis. This surgery involves resurfacing the ends of your knee joint bones, including the femur (or thigh bone) and tibia bone. This process is similar to capping a tooth.
The answer: a resounding yes! In fact, people with knee osteoarthritis who walk for exercise are significantly less likely to go on to develop worse pain, according to a 2022 study published in Arthritis & Rheumatology.
Examples of aerobic exercises that are easy on joints include walking, bicycling, swimming and water aerobics. Try to work up to 150 minutes of somewhat hard aerobic exercise every week. You can exercise 10 minutes at a time if that's easier on your joints.
Genetics notwithstanding, Sheth said there are some factors that can potentially stave off a knee replacement. Keeping body weight down eases the impact on the knee. And when exercising, Sheth said avoiding activities that cause pounding or other possible trauma to the knee can better preserve cartilage.
The gel injections tend to be effective for about 50% of patients, but for those that it works well for those patients tend to see improvement in VAS scores for at least 4-6 months.
The idea behind these injections is that they will temporarily restore the natural function of the knee by injecting a substance which will provide cushioning and reduce bone-on-bone contact. Individual responses vary, but many patients experience months, if not potentially a year or more of relief.
Cartilage Regeneration Options
MACI is a surgical procedure that uses cartilage-forming cells from your body to restore damaged cartilage in the knees. It involves a biopsy to harvest chondrocytes (cartilage-forming cells), which are allowed to multiply in a lab, and surgery to implant them into the damaged area.
Severe knee cartilage loss makes walking, sitting, standing, squatting, and going up and down stairs extremely painful. People with a total loss of knee cartilage can benefit from joint injections. In many cases, surgery including a total knee replacement is needed to treat no cartilage in the knee.
The Natural-Knee (NK) total knee arthroplasty (TKA) system has been in use for 25 years. The unique fea- tures of this system include a deep trochlear groove, an asymmetrical tibial baseplate, use of Cancellous- Structured Titanium coating for preferred bone ingrowth, and a bimetal cementless femoral component.
As knee arthritis progresses, the knee becomes much looser and more unstable. In some cases, this is mild. In other cases, it is substantial enough that cause the patient to fall. Patients who have bone-on-bone arthritis and are starting to fall because of it should strongly consider surgery.
Doctors sometimes recommend that people under age 60 wait to undergo a knee replacement, because these artificial joints typically last only about 15 to 20 years. If someone younger gets the procedure, the joint will likely need to be replaced again down the line.
The majority of patients expect to be able to kneel after TKR,2,4,5 however, these expectations are frequently not met,1,6 with between 50% and 80% of patients reporting that they have difficulty kneeling or do not kneel in the months and years after TKR.
The cartilage damage associated with arthritis is irreversible, but there are nonsurgical and surgical treatments that can help reduce pain, increase joint flexibility and improve overall quality of life for people with knee arthritis.
In a healthy joint cartilage aids in the congruency of movement of the joint between the two bones. Thus if someone has a joint which is “Bone on Bone” it suggests the amount of cartilage on the bones in the joint is reduced and inflammation present. Some research has found a correlation between knee pain and OA.
Rest, ice, compression, and elevation (RICE) are key ways to help ease knee pain and reduce inflammation, especially when the pain is caused by a minor injury or an arthritis flare up. Take some time to rest, use ice packs to reduce swelling, wear a compressive bandage, and elevate your knee whenever possible.
Physiotherapists provide treatments you may need when knee pain makes it hard to move around and do everyday tasks. These treatments may help you move better and relieve pain. You might only be able to have a couple of visits with a physiotherapist.
Avoid high-impact workouts and exercises if you have osteoarthritis of the knee, hip, or ankle. These activities often place stress on weight-bearing joints. Basketball, football, hockey, and soccer are all examples of high-impact sports.
