HIP SURGERY
Total Knee Replacement
Total knee replacement is a surgical procedure to resurface a knee joint damaged by end-stage arthritis or significant structural injury. When treatments like physiotherapy and medication no longer manage symptoms, this procedure offers a clinical option to help improve joint function and mobility. Dr David Kitchen provides specialised assessment for total knee replacement at the sportsmed Stepney and Henley Beach clinics.
What is a Total Knee Replacement?
In a damaged knee, the protective cartilage has worn away, which leads to painful bone-on-bone contact. A total knee replacement involves removing the worn surfaces of the knee joint and replacing them with artificial components.
During surgery, the damaged ends of the thigh bone and shin bone are resurfaced with durable metal implants. A specialised medical-grade plastic spacer is placed between them to act as a new gliding surface. This mechanical reconstruction is designed to help the joint to move more freely during daily activities.
Common Symptoms of End-Stage Joint Damage
Osteoarthritis is the primary reason for this procedure, but other conditions such as rheumatoid arthritis or avascular necrosis can also cause these symptoms:
Persistent pain and discomfort that continues during rest or interrupts sleep.
Loss of essential function such as difficulty with weight-bearing for walking or standing.
Joint line pain like a localised discomfort that worsens with weight-bearing or high-impact activity.
Locking, where the knee may stick, often caused by a piece of cartilage floating in the joint fluid.
When is Surgery Considered?
A clinical review with Dr David Kitchen may be recommended when:
Conservative measures are exhausted
Pain persists despite weight management, activity changes and non-surgical therapies. Pain at night is a strong indicator that this condition warrants further review.
Imaging confirms damage
X-rays or scans show significant loss of joint space or bone-on-bone contact.
Impact on quality of life
The condition prevents participation in social or physical activities.
Failed previous repairs
When earlier surgeries (like an osteotomy) are no longer effective.
Potential Benefits of Total Knee Replacement Â
A detailed clinical assessment at our Stepney or Henley Beach clinics, supported by imaging, is necessary before making a treatment decision. Dr David Kitchen will discuss all surgical and non-surgical options with you.
Pain Reduction Â
The surgery functions to address the source of mechanical joint pain.
Correct Joint Alignment
Corrects limb alignment to support a walking pattern more natural to you.
Increase Functional Range
Helps increase the ability to bend and straighten the knee.
Implant Durability
High-performance medical components support weight-bearing and movement for 15-20 years.
About the Surgery
The procedure is typically performed at Burnside Hospital Stepney, Ashford Hospital or Western Hospital. Dr David Kitchen uses detailed pre-operative mapping to align the new components with your individual anatomy.
- Resurfacing
Only the damaged surface of the bone is removed to accommodate the implant.
- Soft Tissue Balancing
The ligaments are carefully tensioned to support joint stability.
- Modern Materials
The implants are made from biocompatible alloys and advanced plastics.
Recovery & Rehabilitation
Day
1 - 3
Initial Recovery
Pain management and assisted walking with a physiotherapist.
Week
2 - 6
Early Mobility
Transitioning to independent walking and focusing on wound care. Recovery focuses on early movement to support blood flow and prevent joint stiffness.
Month
2 - 4
Functional Training
Guided exercises at our Stepney clinic to strengthen the supporting muscles.
Month
6 - 12
Long-term Healing
Gradual reduction in swelling as the joint becomes fully integrated.

Risks & Complications
Arthroscopic (keyhole) cartilage surgery is common but it is important to understand the potential risks:
