Dr Hocking is experienced in both total and partial knee replacements, utilising advanced techniques, including robotic-assisted surgery. This innovative technology enhances precision during the procedure, allowing for patient specific optimised alignment of the artificial components and the best possible outcome for patients.
Total knee replacement, also known as total knee arthroplasty, is a surgical procedure aimed at relieving pain and restoring function in patients with severe knee joint damage. During this procedure, Richard removes the damaged surfaces of the knee joint and replaces them with artificial components designed to replicate natural joint movement.
The knee joint consists of three main bones: the femur (thigh bone), the tibia (shin bone), and the patella (kneecap). In a healthy knee, the meniscus—soft cartilage located between the femur and tibia—acts as a cushion and helps absorb shock during movement. However, conditions such as osteoarthritis, rheumatoid arthritis, or injury can lead to the degeneration of these structures, causing pain, stiffness, and a reduced range of motion.
Throughout the treatment process, Dr Hocking prioritises personalised care, working closely with each patient to develop a tailored approach that suits their individual needs and lifestyle. After surgery, rehabilitation plays a crucial role in the recovery journey; Richard is committed to supporting his patients as they regain mobility and return to their daily activities.
Overview
Causes
The exact cause of osteoarthritis is unclear, but several factors may contribute, including:
- Joint injuries or trauma
- Fractures near the knee
- Family history of arthritis
- Obesity
- Repetitive joint overuse
- Joint infections
- Inflammatory conditions like rheumatoid arthritis
- Connective tissue disorders
Diagnosis
Diagnosis is based on medical history, physical examination, and X-rays, which typically show narrowed joint space in the arthritic knee.
Procedure
The goal of total knee replacement is to alleviate pain and restore knee function and alignment. The surgery is performed under spinal or general anesthesia. The steps include:
- Making an incision to the side of the knee to expose the joint.
- Using computer navigation to accurately cut the bones.
- Removing damaged portions of the tibia and femur at specific angles with the robot cutting device.
- Implanting the tibial and femoral components.
- Preparing the patella to ensure smooth movement over the new knee.
- Testing the knee’s range of motion before closing the incision and applying a sterile dressing.
Post-Operative Care
Rehabilitation starts immediately after surgery. A physical therapist will guide you through exercises to strengthen the leg and restore knee mobility. You will be able to walk with assistive devices, and a home exercise program will be provided.
