What procedure was performed on the patient diagnosed with left knee osteoarthritis?

Knee arthroplasty, also known as knee replacement, is commonly indicated for patients diagnosed with left knee osteoarthritis when conservative treatments have failed to alleviate pain and improve function. This procedure involves the surgical replacement of the damaged or degenerated joint surfaces of the knee with artificial components, which provide relief from the painful symptoms associated with osteoarthritis and restore mobility.

In the context of managing osteoarthritis, knee arthroplasty is often recommended for patients who experience severe pain, significant loss of function, and deformities due to the degeneration of cartilage and underlying bone. This approach offers long-term benefits and can lead to a substantial improvement in the quality of life for those suffering from advanced osteoarthritis.

While other procedures, such as arthroscopy, osteotomy, or cyst excision, may be considered for various knee conditions, they do not address the degree of joint damage and pain typically associated with advanced osteoarthritis as effectively as a knee arthroplasty. Arthroscopy is less invasive and is primarily utilized for diagnostic purposes or minor repairs, while osteotomy involves cutting and reshaping bone, which is generally performed to realign the joint and is more suitable for younger patients with specific types of knee misalignment. Excision of a cyst does not address oste
