Knee Arthroscopy Procedure vs Open Surgery: Which is Better?

When dealing with knee injuries, choosing the right treatment is crucial for a smooth recovery and long-term joint health. Two common procedures in Singapore are knee arthroscopy and open surgery. While both methods effectively treat knee conditions, they differ in terms of invasiveness, recovery time, and risks. Understanding these differences will help you make an informed decision about the best option for your needs.

What is a Knee Arthroscopy?

Knee arthroscopy is a minimally invasive surgical procedure to diagnose and treat knee problems. A surgeon inserts a small camera, called an arthroscope, through tiny incisions around the knee. This camera provides a clear view of the joint, allowing the surgeon to perform necessary repairs using specialised instruments.

Common conditions treated with knee arthroscopy include:

• Torn meniscus
• ACL (anterior cruciate ligament) injuries
• Cartilage damage
• Loose bone fragments
• Knee inflammation (synovitis)

Because arthroscopy involves small incisions, patients typically experience less pain, minimal scarring, and faster recovery than with open surgery.

What is Open Surgery for Knee Injuries?

Open knee surgery, also known as traditional knee surgery, is a more invasive approach where a surgeon makes a larger incision to access and repair the damaged structures inside the knee. This method is usually necessary for severe cases, such as:

• Total knee replacement
• Complex ligament repairs
• Major bone fractures
• Severe osteoarthritis requiring joint reconstruction

While open surgery allows for a more comprehensive repair, it typically involves a longer hospital stay, a more extended recovery period and a higher risk of complications compared to knee arthroscopy.

Key Differences Between Knee Arthroscopy and Open Surgery

Both knee arthroscopy and open surgery serve important roles in knee treatment, but they have distinct differences:

	Knee Arthroscopy	Open Surgery
Incision Size	Small (few mm)	Large (several cm)
Invasiveness	Minimally invasive	Highly invasive
Scarring	Minimal	More noticeable
Recovery Time	Faster (weeks)	Longer (months)
Hospital Stay	Often outpatient	Requires hospitalization
Pain & Swelling	Less severe	More intense
Suitability	Mild to moderate knee issues	Severe knee damage

Benefits of Knee Arthroscopy Procedure

Knee arthroscopy is preferred by those who want a minimally invasive option. Some of the main benefits include:

• Shorter Recovery Time – Most patients resume daily activities within a few weeks.
• Less Post-Operative Pain – Smaller incisions result in reduced pain and swelling.
• Lower Risk of Complications – Minimal blood loss and a lower risk of infections compared to open surgery.
• Outpatient Procedure – Many arthroscopy patients can go home the same day.
• Improved Accuracy – The arthroscope provides a clearer view of the knee joint, allowing for precise surgical interventions.

These advantages make arthroscopy a great option for patients who need quick recovery with minimal disruption to their lifestyle.

When Open Surgery is the Right Option

Despite the benefits of arthroscopy, open surgery may be better for some people. Open surgery is recommended when:

• The knee joint is severely damaged or deformed.
• The patient has advanced arthritis requiring a full knee replacement.
• There are complex ligament or cartilage injuries that cannot be managed with minimally invasive techniques.
• The injury involves large bone fractures that need realignment and stabilization.

Although recovery from open surgery takes longer, it provides long-term relief and stability for severe knee conditions.

Recovery Expectations: Knee Arthroscopy vs. Open Surgery

Recovery timelines differ depending on the type of surgery performed. Here’s what to expect:

Knee Arthroscopy Recovery

• First few days: Rest, ice, and keep the knee elevated.
• 1-2 weeks: Start light physical therapy and return to daily activities.
• 3-6 weeks: Gradual increase in activity, with most patients resuming normal movement.
• 3 months: Full recovery for most non-athletes.

Open Knee Surgery Recovery

• First few weeks: Limited mobility, requiring crutches or a walker.
• 1-2 months: Begin rehabilitation to regain strength and movement.
• 3-6 months: Steady improvement, but still avoiding high-impact activities.
• 6-12 months: Full recovery, depending on the complexity of the surgery.
