Knee Conditions
Dr. Stewart treats a full range of knee conditions — from meniscus tears and ligament injuries to advanced arthritis and joint replacement. Understanding your diagnosis is the first step toward the right treatment plan.
Common Symptoms
The leading reason for knee replacement surgery, osteoarthritis occurs when protective cartilage wears away and bones begin to rub against each other. Pain worsens progressively with activity, climbing stairs, and prolonged standing. Dr. Stewart uses Mako robotic-arm technology to perform partial and total knee replacements with personalized precision, based on a pre-operative CT scan of your specific anatomy.
The meniscus is a C-shaped cushion between the thigh and shin bones. Tears cause pain, swelling, catching, and locking. Can result from a sudden twist or gradual wear in older patients.
A tear of the anterior cruciate ligament, one of the four main knee ligaments. Often caused by sudden stopping, pivoting, or direct contact. Causes immediate pain, swelling, and a feeling that the knee gives way.
Inflammation of the tendon connecting the kneecap to the shinbone. Known as jumper's knee, it causes pain below the kneecap that worsens with running, jumping, and kneeling. Common in active and athletic patients.
The medial collateral ligament runs along the inside of the knee. Sprains or tears are often caused by a blow to the outside of the knee. Causes inner knee pain, swelling, and a sense of instability.
A fracture of the top surface of the shinbone, which forms the lower half of the knee joint. Often caused by high-energy trauma such as a car accident or fall. Causes significant pain, swelling, and inability to bear weight.
The kneecap slips out of its groove, usually to the outside of the knee. Causes sudden pain, swelling, and a visible deformity. Common in young active patients and may recur without treatment.
A tear of the tendon connecting the quadriceps muscle to the kneecap. A complete tear causes immediate inability to straighten the knee. More common in patients over 40 and often requires surgical repair for full recovery.
Knee replacements can fail due to wear, loosening, instability, or stiffness. Revision surgery is more complex than the original but can restore function and relieve pain when the primary implant is no longer performing.
Infection around a knee implant is a serious complication requiring urgent attention. Signs include increasing pain, warmth, swelling, drainage, and fever. Treatment typically involves surgery combined with targeted antibiotic therapy.
