Knee Arthroscopy / Meniscectomy
How is a Knee Arthroscopy / Meniscectomy performed?
A knee arthroscopy is a minimally invasive procedure performed through small incisions to diagnose and treat problems inside the knee joint. A camera (arthroscope) is inserted into the knee, allowing the surgeon to view the joint on a monitor in real time.
A meniscectomy refers to the removal of a torn portion of the meniscus, which is the tissue that cushions and stabilizes the knee joint. The goal is to remove only the damaged part of the meniscus while preserving as much healthy tissue as possible to maintain knee function and reduce the risk of arthritis.
The procedure usually takes 30–45 minutes and is performed under general anaesthesia. Most patients go home the same day.
What Is the Recovery in the Immediate Postoperative Period?
Hospital stay: Most patients go home the same day of surgery.
Weight bearing: You will walk on the operated leg immediately with gait aids.
Brace: No braces are required after surgery.
Range of motion: Early motion starts right away.
Ice and elevation: Used frequently to control pain and swelling. You should ice for 20 minutes, 3–4 times per day, right after surgery.
Assistive devices: You will typically use crutches for 1–2 weeks after surgery. It can take up to 2-3 weeks before you can walk independently.
How Is the Wound Managed?
Bulky dressings will be removed 1–2 days after surgery. It is normal for arthroscopic fluid to drain into this dressing.
A waterproof underlay dressing should be left on for 7 days.
Incisions typically heal within 2 weeks.
Showers are permitted while wounds are covered with waterproof dressings during the first 2 weeks.
Do not submerge incisions in water (baths, pools, or ocean) for 4 weeks.
A wound check with your GP, allied health provider, or our clinic is recommended at 2 weeks.
Absorbable sutures are usually used and do not require removal, though small remnants may surface naturally during healing.
How Do I Prevent Blood Clots (DVT/PE)?
Blood clots (deep vein thrombosis or pulmonary embolism) can occur after surgery but is rare after knee arthroscopy.
You can reduce the risk by:
Moving your foot and ankle regularly while resting.
Walking early with assistance.
Avoiding long periods of sitting or immobility.
You will likely take aspirin for 2 weeks to prevent DVT/PE. If you have a history of blood clots or risk factors, a stronger blood thinner may be prescribed.
If you plan any long-distance travel within 4-6 weeks of surgery, please inform our clinic for preventative medication.
Seek immediate medical attention if you develop calf pain, swelling, chest pain, or shortness of breath.
How Do I Manage My Pain After a Knee Arthroscopy / Meniscectomy?
Local anaesthetic will be injected into the knee during surgery.
Use ice regularly (20 minutes, 3–4 times per day). • Take prescribed pain medication as directed. Opioids may be used short-term but have known side effects (nausea, constipation, dependence). Non-opioid medications are preferred when tolerated.
Use a compression dressing on the knee for 6 weeks to manage swelling.
Begin gentle range-of-motion and muscle activation exercises as soon as recommended.
Use walking aids for stability while recovering your gait.
What Issues Should I Call the Clinic Regarding?
You should contact your surgeon or clinic immediately if you notice:
Increasing redness, swelling, or drainage from the wound.
Persistent or worsening pain not controlled by medication.
Fever, chills, or night sweats.
Calf pain or swelling (possible blood clot).
Any acute injury to your operative knee.
Prompt review allows early management of potential complications.
When Can I Return to Normal Activities After Knee Arthroscopy / Meniscectomy?
Return to activities depends on the nature and intensity of the activity.
General guideline:
Walking: Start immediately after surgery
Running: Can start after pain and swelling resolved (typically 6 weeks)
Stationary cycling: Can start right away and is encouraged. Road cycling can take 4–6 weeks.
Light gym exercise (Pilates, pool work, yoga): 4–6 weeks.
Sport: Typically 12–16 weeks, depending on intensity.
When Can I Drive?
You can usually drive once you can safely control the vehicle and perform an emergency stop comfortably.
This is typically 2–4 weeks after right knee surgery, and 1–2 weeks for the left knee.
You must not drive while taking strong pain medication (e.g., opioids).
When Can I Return to Work?
Return to work depends on your occupation:
Office or sedentary work: 1–2 weeks (once you can commute safely).
Light manual work: 2–4 weeks.
Heavy manual labour: 6–8 weeks or longer, depending on recovery.
Should I See a Physiotherapist?
A formal physiotherapist consultation is not needed but may benefit some patients who require a guidance during their rehab.
Your physiotherapist will:
Guide you through a structured rehabilitation program.
Focus on restoring range of motion, strength, balance, and gait mechanics.
Progress exercises gradually from early mobility to functional activity and low-impact sport.
Most patients continue physiotherapy for 2–6 weeks to achieve full functional recovery.
What Are the Complications After a Knee Arthroscopy / Meniscectomy?
While knee arthroscopy and meniscectomy are safe and commonly performed procedures, all surgeries carry some risk. Potential complications include:
Infection (superficial or deep)
Blood clots (DVT/PE)
Stiffness or loss of motion
Persistent pain or swelling
Damage to cartilage or nearby structures, including progression of arthritis
Fluid accumulation in the knee (effusion)
Recurrent meniscal tearing or ongoing mechanical symptoms
Numbness around incision sites
