Frequently Asked Questions
How do I know if it's time for a hip or knee replacement?
Common signs include pain that limits walking, stairs, or sleep; stiffness that doesn't improve with rest; and reduced response to conservative treatments like anti-inflammatory medication, injections, or physical therapy. A consultation and imaging review with Dr. Vojdani can help clarify whether joint replacement is the right next step for you.
What is the difference between anterior and posterior hip replacement?
The anterior approach accesses the hip through an interval between muscles at the front of the hip, without detaching major muscle groups. The posterior approach, a traditional technique, accesses the hip from behind and involves a brief release and repair of certain muscles and tendons. Both approaches can produce excellent results — the right choice depends on individual anatomy and surgical history, which Dr. Vojdani will review with you.
Am I a candidate for partial knee replacement instead of total knee replacement?
Partial knee replacement is appropriate only when arthritis is confined to a single compartment of the knee, with the remaining ligaments and cartilage still healthy. Imaging and a physical exam are needed to confirm this before it can be recommended over a total knee replacement.
