General FAQ

We have compiled a few questions on hip and knee replacement surgeries and arthroscopic procedures that we perform. Joint replacement surgery and minimally invasive procedures (arthroscopic surgery) are our major services at Atlantic Bone and Joint Centre.

Hip replacement

Technological advancements and improvements in anaesthesia enable hip replacement surgery to take place as an outpatient procedure, mainly in the United States of America. At Atlantic Bone and Joint Centre, however, Dr Naidu does not endorse this practice for reasons of patient safety and to ensure the best possible outcomes. We do, however, endeavour to make the patient stay in hospital as comfortable and as short as possible, no more than is necessary.

We will need to replace your hip joint should you sustain a fracture of the femoral neck (hip fracture) or after developing painful arthritis. Sometimes, an existing hip replacement can become worn out, resulting in pain, and may require a revision hip replacement.

Treatment failure of hip injury, avascular necrosis of the hip (AVN), osteoarthritis, rheumatoid arthritis, bone tumours and a hip disease as a result of a congenital abnormality through conservative therapies may require hip replacement.

Assistive walking devices such as crutches and canes are suggested to aid in your recovery. Strict adherence to the physical therapy regime from your physiotherapist will ensure the best outcomes. During this time, you cannot engage in intensive weight-bearing exercises and must practise safe wound management in terms of caring for sutures/dressings by not disturbing or removing them. Make sure to attend follow-up appointments and take the medication and supplements that Dr Naidu prescribes. Remember to alert every healthcare provider you visit thereafter to your new hip joint. You may require prophylactic antibiotics when undergoing certain procedures, like dental work.

Knee replacement

Knee replacement surgery aims to treat pain and improve joint mobility. Osteoarthritis is a condition that causes pain due to degenerative joint cartilage that wears away over time. Osteoarthritis makes it difficult to carry out routine tasks because bending at the knee is much more challenging to do.

Irreversible knee injuries include:

  • Cartilage wear or injuries
  • Ligament tears
  • Fractures

With any procedure, a complication may arise. Although rare, some complications with knee replacement are:

  • Excessive bleeding 1%
  • Infection 2%
  • Blood clots developing in the lungs or legs 2%
  • Pain
  • Joint stiffness

Dr Naidu will explain what you can expect regarding how he performs knee replacement as well as what occurs afterwards. He will advise on recovery and how to plan in advance prior to surgery. After taking your medical history, Dr Naidu will carry out a detailed physical exam to study your health and decide whether you are suitable for knee surgery. This is an opportune time to bring up any allergies you have, especially in regards to anaesthesia. If both you and Dr Naidu agree that knee replacement is the best option, you will be given a date for the admission and procedure. From midnight, the day of the procedure, you will not be allowed to eat anything, and you must fast for at least 6 hours before surgery. In addition, after discharge, typically three to five days, someone will need to assist you around the house for the first few weeks. As an alternative, Step Down care may be arranged, please discuss this with Dr Naidu beforehand.

Arthroscopic surgery

Knee arthroscopy, also known as keyhole surgery, is a less invasive surgical technique that entails the use of an arthroscope to diagnose and treat various knee conditions causing knee pain. In addition, the microscopic camera and light attached at the end of the arthroscope can be used to visualise the inside of the knee joint extensively. It is also used to treat various articular and ligament injuries with the use of specialised instruments.

Pain in the knee is due to overactivity or excessive strain on the knee joint. Being on your feet all the time before your thigh muscles are strengthened can also contribute to knee pain. In addition, swelling, which is normal after arthroscopic surgery, causes knee pain. This pain and swelling improve as you closely follow the guidance of your physical therapist.

You can expect minor discomfort in the knee after arthroscopic surgery for several days. Recovering from this surgery involves strengthening the thigh muscles and minimising swelling and pain.

Knee arthroscopy presents risks of:

  • Bleeding
  • Infection
  • Knee stiffness
  • Damage to internal structures (ligaments, cartilage and blood vessels) of the knee joint.
