In cases where conservative treatments are not sufficient, surgical options may be considered for severe knee osteoarthritis. These surgical interventions aim to alleviate pain, restore function, and improve the patient’s quality of life.
Arthroscopic Surgeries
One surgical option for knee osteoarthritis is arthroscopy. This minimally invasive procedure involves inserting a small camera, called an arthroscope, into the knee joint through small incisions. The surgeon can then use specialized tools to repair damaged cartilage, remove loose fragments, or smooth rough surfaces. Arthroscopy can also be used for cartilage resurfacing, where damaged cartilage is smoothed or replaced with healthy tissue.
Joint Replacement Surgeries (Arthroplasty)
In cases where the knee joint is significantly damaged, joint replacement surgeries may be recommended. This procedure involves removing the damaged joint surfaces and replacing them with artificial implants, known as prosthetic joints. The most common type of joint replacement surgery for knee osteoarthritis is a total knee replacement (TKR), where both the femoral and tibial components of the knee joint are replaced. Partial knee replacement (PKR), where only the affected part of the knee joint is replaced, may be considered in certain cases.
Osteotomy
In some cases, where the osteoarthritis is confined to one side of the knee joint, an osteotomy may be recommended. This procedure involves cutting and realigning the bones around the knee joint to redistribute the load and relieve pressure on the damaged area. Osteotomy aims to delay or prevent the need for joint replacement surgery, particularly in younger patients with good bone quality.
Joint Fusion (Arthrodesis)
Joint fusion is another surgical option for severe knee osteoarthritis. This procedure involves permanently fusing the bones in the knee joint together, eliminating the joint and creating a single bone. Joint fusion is typically reserved for patients who are not suitable candidates for joint replacement surgery or for those who require significant stability in the joint, such as in cases involving severe deformities or infections.
It is important to note that the choice of surgical treatment for knee osteoarthritis depends on various factors, including the severity of the condition, the patient’s overall health, and their specific needs and goals. A thorough evaluation and consultation with an orthopedic surgeon is essential to determine the most appropriate surgical option.
