Knee pain can slowly take over your life. Whether it’s climbing stairs, walking around the shops, or simply enjoying time with family, sore and stiff knees can make every move a challenge. For many people in Perth, total knee replacement surgery offers a second chance at living pain-free.

But what really happens before, during, and after this procedure? And what should you expect from the journey? Let’s break it down step by step in this patient-friendly guide.

Understanding Total Knee Replacement

What Is Total Knee Replacement?

Total knee replacement, sometimes called total knee arthroplasty, is a surgical procedure where a damaged knee joint is replaced with an artificial implant. The aim is to reduce pain, improve mobility, and restore function.

The procedure is most often recommended for patients suffering from:

• Severe osteoarthritis
  
  

• Rheumatoid arthritis
  
  

• Post-traumatic arthritis
  
  

• Degenerative joint disease
  
  

According to the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), more than 60,000 knee replacements are performed in Australia each year, and the number continues to rise as the population ages.

Why Patients Consider Knee Replacement

Living with chronic knee pain is more than just discomfort; it can affect your physical health, emotional well-being, and independence.

Common reasons patients in Perth choose surgery include:

• Inability to walk short distances without pain
  
  

• Difficulty climbing stairs
  
  

• Night pain that disturbs sleep
  
  

• Limited mobility affects work and hobbies
  
  

• Swelling, stiffness, and joint deformity
  
  

Preparing for Surgery

The Initial Consultation

Your journey usually begins with a detailed consultation with an orthopaedic specialist. During this visit, your medical history, lifestyle, and expectations will be discussed. Imaging tests such as X-rays or MRIs help confirm the extent of damage in the knee.

Pre-Surgery Assessments

Before undergoing surgery, patients may need:

• Blood tests
  
  

• ECG (heart check)
  
  

• General health evaluation
  
  

• Prehab (pre-surgery physiotherapy to strengthen muscles)
  
  

This preparation ensures you are in the best possible condition for a smooth recovery.

The Surgical Procedure

How It Works

Total knee replacement surgery typically takes 1 to 2 hours. The procedure involves:

1. Removing damaged cartilage and bone from the surface of the knee joint.
   
   

2. Shaping the underlying bone to fit the implant.
   
   

3. Inserting metal and plastic components to restore alignment and function.
   
   

4. Closing the incision with sutures or staples.
   
   

Modern techniques often use minimally invasive approaches, resulting in smaller cuts and faster healing.

Anaesthesia Options

Patients usually receive either general anaesthesia (asleep) or spinal anaesthesia (awake but numb from the waist down). Your surgeon will recommend the safest option.

Recovery Timeline

Immediately After Surgery

• Patients spend 2–3 days in the hospital.
  
  

• Physiotherapy begins within 24 hours.
  
  

• Walking aids such as crutches or a walker are introduced early.
  
  

First 6 Weeks

• Most patients gradually regain mobility.
  
  

• Pain and swelling improve with medication and therapy.
  
  

• Stitches or staples are usually removed at 10–14 days.
  
  

3 to 6 Months

• Major improvements in movement and strength are noticeable.
  
  

• Many patients can return to driving within 6 weeks.
  
  

• Low-impact activities like swimming and cycling become possible.
  
  

Long-Term Results

A successful knee replacement can last 15–20 years. According to the AOANJRR, over 90% of implants are still functioning well after 15 years, making it a long-term solution for chronic knee problems.

Benefits of Total Knee Replacement

Patients report significant improvements in:

• Pain relief (over 90% of patients experience a major reduction in pain)
  
  

• Ability to walk longer distances
  
  

• Improved sleep quality
  
  

• Better mental health and confidence
  
  

• Return to hobbies such as gardening, golf, or travel
  
  

Risks and Complications

Like any surgery, knee replacement comes with risks, although serious complications are rare. Possible risks include:

• Infection (about 1–2% of cases)
  
  

• Blood clots (DVT)
  
  

• Implant loosening over time
  
  

• Knee stiffness
  
  

• Nerve or blood vessel injury (rare)
  
  

Your surgeon will take measures to minimise these risks, including antibiotics, blood-thinning medication, and early mobilisation.

Life After Knee Replacement

Returning to Daily Activities

Most patients return to independent living quickly. Driving may be possible after 6 weeks, depending on progress. Many people go back to desk jobs in a month, while more physical work may require a few months.

Sports and Exercise

High-impact activities such as running or jumping are discouraged, but you can enjoy:

• Walking
  
  

• Swimming
  
  

• Golf
  
  

• Cycling
  
  

• Yoga and Pilates (with modifications)
  
  

Staying active helps protect your new joint and overall health.

Choosing the Right Surgeon in Perth

Selecting an experienced surgeon is key to ensuring the best outcome. Patients often seek specialists who focus on joint replacements and sports injuries. For those considering surgery, the expertise of the best orthopaedic surgeon in Perth can make a significant difference in recovery and long-term results.

Tips for a Smooth Recovery

• Follow physiotherapy instructions closely to regain strength.
  
  

• Maintain a healthy diet rich in protein, vitamins, and minerals for healing.
  
  

• Keep moving safely to prevent blood clots.
  
  

• Attend follow-up appointments to monitor progress.

• Over 85–90% of patients report being satisfied with the results of their surgery.
  
  

• Most regain the ability to perform everyday tasks without pain.
  
  

• Many report significant improvements in quality of life, mobility, and independence.
