Knee problems can happen to anyone, athletes, workers, or older adults. They can range from minor injuries to conditions that require surgery. In Perth, patients have access to advanced treatments and skilled specialists who focus on restoring mobility and reducing pain.

This guide explains the most common knee surgeries, from ACL reconstruction to knee replacement, and what patients can expect during treatment and recovery.

Understanding Knee Pain

The knee is the largest joint in the body. It connects the thigh bone (femur) to the shin bone (tibia) with the help of ligaments, cartilage, and tendons.

Because the knee bears so much weight and movement, it is prone to injury and wear.

Common Causes of Knee Problems

• Sports injuries such as ACL tears and meniscus damage

• Osteoarthritis, which affects more than 2.2 million Australians

• Fractures from falls or accidents

• Overuse injuries from work or exercise

• Age-related changes causing stiffness and pain

ACL Injuries

What is the ACL?

The anterior cruciate ligament (ACL) is one of the four major ligaments in the knee. It stabilises the joint and allows quick movements like pivoting or jumping.

How Do Injuries Happen?

ACL injuries usually occur during sports such as soccer, basketball, and netball. A sudden twist, landing awkwardly, or direct contact can tear the ligament.

Treatment Options

• Non-surgical management with physiotherapy may be suitable for less active patients.

• ACL reconstruction surgery uses a tendon graft to replace the torn ligament.

Recovery time: Most patients need 6–12 months before returning to full activity.

Meniscus Tears

The Role of the Meniscus

The meniscus is a piece of cartilage that cushions the knee joint. Each knee has two menisci, which act like shock absorbers.

Symptoms of a Tear

• Pain and swelling

• A catching or locking feeling

• Difficulty bending the knee fully

Arthroscopic Surgery

Meniscus tears are often repaired using arthroscopy, a minimally invasive surgery. Surgeons use a small camera and tools to trim or repair the damaged cartilage.

Benefits of arthroscopy include:

• Small incisions

• Faster recovery

• Less scarring

Knee Replacement

When is Replacement Needed?

If arthritis or severe injury destroys the knee joint, replacement may be the best option.

Types of Surgery

• Total Knee Replacement (TKR): The entire joint is replaced with artificial parts.

• Partial Knee Replacement (PKR): Only the damaged section is replaced.

Success and Longevity

According to the Australian Orthopaedic Association National Joint Replacement Registry, more than 65,000 knee replacements are performed annually in Australia. Over 90% last 15–20 years.

Most patients report dramatic improvements in mobility and pain relief after surgery.

Comparing Surgical Options

Recovery and Rehabilitation

Surgery is only one part of treatment. Recovery requires structured rehabilitation.

Early Stage (Weeks 1–6)

• Use of walking aids

• Pain and swelling control

• Gentle exercises with a physiotherapist

Mid Stage (Months 2–4)

• Strength-building exercises

• Improved range of motion

• Return to light activities

Long-Term Recovery (6–12 Months)

• Return to sports or heavy physical activity

• Long-term mobility improvements

• Ongoing exercises for joint health

Risks of Knee Surgery

All surgeries have risks, though they are generally low.

Possible risks include:

• Infection

• Blood clots

• Stiffness

• Wear or loosening of implants (in replacements)

Perth hospitals maintain strict safety standards, making outcomes reliable for most patients.
