Are There Alternatives to Knee Replacement Surgery?
Knee replacement surgery is generally considered when non-surgical treatments are no longer able to provide adequate symptom relief. Depending on the severity of your condition, your knee specialist may recommend conservative treatment options before considering surgery.
These may include:
- Physiotherapy to improve strength, flexibility, and joint function
- Activity modification to reduce stress on the knee joint
- Weight management to decrease pressure on the knee
- Pain-relieving and anti-inflammatory medications
- Knee braces or supportive devices
- Corticosteroid injections to reduce inflammation and pain
- Viscosupplementation injections in selected patients
While these treatments may help manage symptoms, they do not reverse advanced joint damage. If knee pain continues to affect your mobility, independence, and quality of life despite these measures, knee replacement surgery may provide a more durable solution.
Dr Wang will discuss the benefits and limitations of each treatment option and recommend an individualised treatment plan based on your condition and goals.
How Do I Prepare for Knee Replacement Surgery?
Proper preparation before knee replacement surgery helps reduce the risk of complications and supports a smoother recovery. Before the procedure, Dr Wang will perform a comprehensive assessment to evaluate your overall health, the severity of your knee condition, and your suitability for surgery.
Medical Evaluation and Diagnostic Tests
A detailed pre-operative assessment is carried out to plan your surgery and identify any factors that may affect recovery. This may include:
- A physical examination of the knee
- Review of your medical history and current symptoms
- Imaging studies such as X-rays or MRI scans to evaluate the extent of joint damage
- Blood tests and other pre-operative investigations, when required
These investigations help your knee specialist determine the most appropriate surgical approach and implant selection.
Preparing for Surgery and Recovery
Inform your doctor about any medications, supplements, or herbal products you are taking. Certain medications may need to be adjusted before surgery to reduce the risk of complications.
You will also receive instructions regarding fasting, medication use, and hospital admission procedures. To support a smoother recovery, it is advisable to:
- Arrange for assistance at home during the initial recovery period
- Remove tripping hazards such as loose rugs or electrical cords
- Keep frequently used items within easy reach
- Have any recommended walking aids or equipment available before surgery
What to Expect During Knee Replacement Surgery
Knee replacement surgery is typically performed under general anaesthesia and usually takes one to two hours.
During the procedure, an incision is made over the knee to access the damaged joint surfaces. Worn cartilage and damaged bone are removed and replaced with artificial components designed to restore knee function, alignment, and stability.
Depending on the extent of joint damage, either part of the knee (partial knee replacement) or the entire joint (total knee replacement) may be replaced.
After the implants are positioned and the knee is assessed for stability and movement, the incision is closed and you will be monitored as you recover from anaesthesia.
How Long Does Recovery Take After Knee Replacement Surgery?
Recovery after knee replacement surgery varies from person to person, depending on factors such as overall health, age, activity level, and the type of procedure performed. Dr Wang follows enhanced recovery protocols designed to support early mobilisation and a faster return to daily activities where appropriate.
Most patients are able to stand and bear weight on the operated leg shortly after surgery unless otherwise advised.
First Few Days After Surgery
Patients typically remain in hospital for one to two days following surgery. During this time, the medical team will monitor recovery, manage pain, and help patients begin walking with the support of physiotherapists and walking aids if required.
Weeks 1 to 2
The focus during the first two weeks is on wound healing, pain control, and gentle exercises to restore knee movement. Patients are encouraged to gradually increase their walking distance and participate in physiotherapy to support recovery.
Weeks 3 to 6
Most patients experience improvements in mobility and confidence with walking. Ongoing physiotherapy and home exercises help improve knee strength and range of motion. Depending on their progress, some patients may reduce their reliance on walking aids and begin returning to more routine daily activities.
Months 2 to 3
Pain and swelling continue to improve, and knee strength and function gradually increase. Many patients may be able to resume driving, return to work, and participate in low-impact activities after discussion with their surgeon. Continued adherence to rehabilitation exercises remains important during this stage.
Months 6 to 12
Recovery continues over several months as strength, flexibility, and overall function improve. Most patients experience significant improvements in mobility and quality of life during this period. Recovery outcomes are often influenced by factors such as overall health, participation in physiotherapy, and adherence to post-operative instructions.
