Knee, Hip & Joint Replacement: Your Questions Answered

Knee replacement is usually considered when arthritis pain continues despite medicines, physiotherapy and injections, and it affects walking, sleep or daily activities, with advanced joint damage on X-ray. The decision is made after an examination and review of your scans.

Dr B S Murthy, Principal Director of Orthopaedics at Max Super Speciality Hospital, Noida, assesses patients for knee replacement at his Noida and Kaushambi (Ghaziabad) consultations.

Robotic knee replacement uses a plan made from imaging, such as a CT scan, and a robotic arm that assists the surgeon in preparing the bone and placing the implant. The aim is accurate alignment and balance. The surgeon still performs and controls the operation. Dr B S Murthy performs robotic-assisted knee replacement at Max Super Speciality Hospital, Noida.

Revision surgery is a repeat operation to replace or adjust a knee or hip implant that has worn, loosened or failed. It is often more complex than a first replacement and needs careful planning. Dr B S Murthy is in charge of complex primary and revision joint replacement cases at Max Super Speciality Hospital, Noida.

Recovery varies from person to person. Most patients begin walking with support within a day or two of surgery, stay in hospital for a few days, and continue physiotherapy for several weeks. Strength and comfort keep improving over the following months.

Modern implants often last 15 to 20 years or more, but this depends on your age, weight, activity level and how well the joint is cared for. Your surgeon can explain what to expect in your case.

Gentle movement often helps, but the wrong exercises can worsen some knee problems. It is safer to have the cause of the pain diagnosed first, then follow exercises suited to your condition.

Hip replacement is considered for severe hip pain and stiffness caused by arthritis, avascular necrosis or a hip fracture, when other treatment has not given enough relief. Total or partial replacement is chosen based on your condition.

Arthroscopy is keyhole surgery done through small cuts using a camera and fine instruments. It is used to diagnose and treat problems of the knee, shoulder and hip, such as meniscus tears and ligament injuries.

Not always. The decision depends on your age, activity level, how unstable the knee feels and whether other structures are injured. Some people manage with physiotherapy, while active people with instability may need ACL reconstruction.
