Total knee replacement (TKR) surgery is often the last resort for patients suffering from chronic knee pain, usually caused by conditions like osteoarthritis, rheumatoid arthritis, or knee injuries. A surgeon considering a patient for TKR undergoes a comprehensive diagnostic process to determine if the procedure is appropriate. This evaluation helps ensure that the surgery will benefit the patient and improve their quality of life. Below are the key factors that a Total Knee Replacement surgeon in Houston, Texas looks for during the diagnosis:
1. Medical History
The first step in diagnosing the need for TKR is reviewing the patient’s medical history. The surgeon will ask about the patient’s previous knee injuries, surgeries, or diagnoses. They will also inquire about the patient’s family history of knee issues, as genetic factors can play a role in the development of knee problems. The surgeon will assess the progression of symptoms, how long the patient has experienced knee pain, and how it has impacted their daily activities, such as walking, climbing stairs, or engaging in sports.
2. Symptom Assessment
A thorough assessment of the patient’s symptoms is crucial. The surgeon will inquire about the severity and type of pain the patient is experiencing. Is the pain constant, or does it occur only during specific activities? Does it improve with rest or worsen with activity? The surgeon will also evaluate the patient’s range of motion, looking for any limitations in bending or straightening the knee. Swelling, stiffness, and locking sensations are other symptoms that are common indicators of advanced knee joint damage, which may lead to the decision for surgery.
3. Physical Examination
The physical examination involves assessing the knee joint’s function. The surgeon will check for signs of deformity, such as a bowed or knocked knee, which may indicate misalignment of the joint. They will also test for joint stability by applying different movements to see how the ligaments and other structures respond. The alignment of the knee and leg will be closely examined, as improper alignment can contribute to the need for a knee replacement. Tenderness, warmth, or noticeable deformities in the joint are also assessed during this stage.
4. Imaging Tests
Imaging plays a critical role in diagnosing the need for knee replacement. X-rays are the most common diagnostic tool used to evaluate the extent of joint damage. The surgeon will look for signs of joint degeneration, such as cartilage loss, bone spurs, or narrowing of the joint space. These are typical indicators that the knee has undergone significant wear and tear, often seen in osteoarthritis. In some cases, additional imaging such as MRI or CT scans may be ordered to get a more detailed view of the cartilage, ligaments, and other structures within the knee.
5. Assessment of Knee Function
To determine whether surgery is necessary, the surgeon will also assess how well the knee functions. This includes an evaluation of the patient’s gait, weight-bearing ability, and balance. If the patient is unable to walk or bear weight on the affected leg without significant pain or discomfort, it may indicate that a total knee replacement is necessary to restore function.
6. Non-Surgical Treatment History
Before recommending surgery, the surgeon will typically assess the effectiveness of any previous non-surgical treatments. These treatments may include physical therapy, medications, knee injections (such as corticosteroids or hyaluronic acid), and lifestyle modifications. If these conservative treatments have not provided significant relief, the surgeon may feel that surgery is the next step.
7. Patient Expectations and Overall Health
The surgeon will also discuss the patient’s expectations and goals for the surgery. Some patients may seek relief from pain, while others may want to return to a specific level of physical activity. Additionally, the surgeon will consider the patient’s overall health, age, and medical conditions to ensure that the patient is fit for surgery and can recover effectively.
A total knee replacement surgeon’s diagnostic process is thorough and involves a combination of medical history, symptom assessment, physical examination, imaging tests, and evaluation of knee function. By carefully considering these factors, the surgeon can determine whether knee replacement surgery is the most appropriate option for the patient. The ultimate goal is to improve the patient’s quality of life by reducing pain, enhancing mobility, and restoring normal knee function.
