A total knee replacement (TKR) is a significant procedure that involves replacing a damaged or worn-out knee joint with an artificial implant. It’s commonly performed to treat conditions like osteoarthritis, rheumatoid arthritis, or traumatic knee injuries. However, before a surgeon decides that TKR is necessary, a thorough and systematic diagnostic process is required. This process allows the surgeon to assess the patient’s condition, determine if the surgery is appropriate, and ensure that the potential benefits outweigh the risks.

Here’s what a Total Knee Replacement surgeon in Houston, Texas typically looks for during diagnosis:

1. Medical History Review

The first step in the diagnostic process involves a comprehensive review of the patient’s medical history. The surgeon will ask about the patient’s current symptoms, including the severity of knee pain, stiffness, and swelling. They’ll also inquire about the duration of these symptoms and how they’ve impacted the patient’s ability to perform daily activities, such as walking, climbing stairs, or even getting out of bed.

Additionally, the surgeon will look for any previous knee injuries, surgeries, or underlying conditions like diabetes or cardiovascular issues that may influence the decision to proceed with TKR. A history of knee trauma or surgery could alter the knee’s biomechanics or increase the risk of complications during surgery.

2. Physical Examination

The next step involves a detailed physical examination of the knee joint. The surgeon will inspect the knee for any visible signs of deformity, swelling, or redness. They will also assess the range of motion (ROM) to determine how much the knee can bend or straighten. Reduced ROM is common in patients who have knee arthritis or joint damage.

The surgeon will test for knee instability, tenderness, and abnormal joint alignment. They might also assess whether there’s significant muscle weakness or atrophy around the knee joint, which often accompanies chronic knee pain and dysfunction. The physical exam helps determine how much the knee is limiting the patient’s function and mobility.

3. Imaging and Diagnostic Tests

X-rays are the primary imaging tool used by knee replacement surgeons to diagnose the extent of damage to the knee joint. X-rays provide a clear picture of the bones, cartilage, and joint space, revealing the degree of arthritis or degeneration. In cases of severe osteoarthritis, the X-rays might show narrowing of the joint space, bone spurs, or changes in the alignment of the knee joint.

Sometimes, if more detailed information is needed, the surgeon may recommend additional imaging techniques like magnetic resonance imaging (MRI) or computed tomography (CT) scans. These provide a more detailed view of soft tissues such as ligaments, tendons, and cartilage, which may be helpful in certain cases of knee damage.

4. Assessing Functional Limitations

A crucial part of the diagnosis is determining the extent to which the knee pain affects the patient’s daily life. Surgeons will ask about functional limitations, such as difficulty walking, standing for long periods, or performing household chores. Understanding how the knee impacts a patient’s overall quality of life helps the surgeon gauge the necessity of a total knee replacement.

If a patient is unable to manage their symptoms through conservative treatments like medication, physical therapy, or joint injections, a total knee replacement may be considered as a viable option.

5. Evaluating Alternative Treatment Options

Before recommending TKR, the surgeon will evaluate whether alternative, less invasive treatments can provide relief. These options may include physical therapy, weight management, corticosteroid injections, or hyaluronic acid injections to lubricate the joint. If these treatments do not provide sufficient relief or if the knee condition continues to worsen, TKR becomes a more favorable solution.

The decision to undergo a total knee replacement is not made lightly. Surgeons rely on a combination of medical history, physical examination, imaging results, and an assessment of functional limitations to determine if TKR is the right course of action. It’s a careful process that takes into account both the severity of the knee damage and the patient’s overall health, ensuring that surgery will provide lasting relief and improve the patient’s quality of life. By looking at all these factors, the surgeon can make an informed recommendation on whether TKR is the best solution for the patient’s knee pain.
