Patient question
When should I see a surgeon to ask about a partial knee replacement?
Quick answer
It is worth asking about a partial knee replacement when arthritis pain is mainly on one side of the knee, usually the inside, and still limits daily life after several months of good non-surgical care. Being assessed before arthritis spreads or the knee stiffens keeps this option open, says Dr. Pablo Gelber, knee surgeon at Aman Hospital in Doha.
Signs it is worth asking
- Pain you can point to on one side of the knee, most often the inner side
- Pain on walking, standing or stairs that is affecting work, prayer or sleep
- Physiotherapy, weight management, pain relief and perhaps injections have been tried properly
- The knee still bends well and straightens nearly fully
- X-rays you have seen already mention arthritis mainly in one compartment
Why timing can matter
A partial replacement needs the other compartments, the ACL and the movement of the knee to be in good condition. If arthritis is left for a long time, it can spread, the deformity can become fixed, or the knee can stiffen. At that point a total replacement may become the more reliable choice. That does not mean rushing, but it is a reason not to delay an assessment when symptoms are steadily worsening.
When a partial is probably not the answer
Pain all around the knee or mainly behind the kneecap, inflammatory arthritis such as rheumatoid arthritis, a torn or absent ACL with instability, a very stiff knee, or a large fixed deformity usually point away from a partial replacement. In younger patients with a bowed leg, an osteotomy may be considered instead.
What to bring and what happens in Doha
Bring previous X-rays, MRI reports and a list of treatments you have tried. At Aman Hospital, Dr. Gelber examines the knee, checks ligament stability and movement, and arranges standing X-rays, sometimes with stress views or an MRI to confirm that only one area is worn. You will get a clear explanation of whether a partial replacement suits you, and of the alternatives.
Frequently asked questions
Can I request a partial replacement if another doctor suggested a total?
You can ask for a second opinion. Some knees suit either; others are clearly better served by a total. A careful examination and the right X-rays decide.
Do I need an MRI before the first visit?
No. Standing X-rays are the starting point. An MRI is ordered only if it would change the decision.
