How long is recovery from a knee arthroscopy?

Knee arthroscopy is a minimally invasive surgical procedure used to diagnose and treat various knee conditions, such as torn cartilage, ligament injuries or inflamed tissue. Recovery times can vary depending on the condition treated, the complexity of the procedure and the patient’s overall health.

What to expect immediately after surgery

Most knee arthroscopy patients usually go home on the same day because typically, this procedure is performed on an outpatient basis. After surgery:

• Pain and swelling: Mild to moderate discomfort and swelling are normal. To help manage these symptoms, ice packs and prescribed pain medication can help.
• Mobility: Patients may be advised to use crutches or a knee brace temporarily to protect the joint and assist with walking.

Typical recovery timeline

• First week:
  • Rest is essential to minimise swelling and promote healing.
  • Gradual movement of the knee is encouraged to prevent stiffness.
  • Physical therapy may begin to restore strength and range of motion.

• Two to six weeks:
  • Most patients can return to light activities, such as walking or office work, within this timeframe.
  • Swelling typically decreases, and pain is manageable with over-the-counter medication.

• Six weeks to 3 months:
  • Depending on the nature of the procedure, patients may resume more strenuous activities, including sports or heavy physical work.
  • Consistent physical therapy plays a key role in regaining full mobility and strength.

Factors affecting recovery

• Type of procedure: More extensive surgeries, such as ligament reconstruction, may require longer recovery times.
• Physical therapy adherence: Following a rehabilitation plan is critical for optimal healing and joint function.
• Overall health: Factors such as age, fitness level and pre-existing conditions can influence recovery speed.

When to consult your doctor

While recovery from knee arthroscopy is generally smooth, it’s important to watch for signs of complications, such as:

• Persistent or worsening pain and swelling.
• Redness or warmth around the knee, which could indicate infection.
• Difficulty bearing weight on the affected leg.

Most patients recover from knee arthroscopy within six to 12 weeks, with significant improvements in mobility and pain relief. Following post-operative instructions and committing to physical therapy are essential for a successful recovery. If you're considering knee arthroscopy, consult your orthopaedic surgeon for personalised advice and expectations based on your specific condition.
