Arthroscopic Meniscectomy
A minimally invasive procedure to remove torn meniscal tissue and restore knee function
The meniscus is a C-shaped cartilage in the knee that cushions the joint and aids in stability. Tears or damage to the meniscus may occur due to injury, repetitive stress, or degenerative conditions such as osteoarthritis.
Arthroscopic meniscectomy is often recommended for
- Tears causing pain, swelling, or mechanical symptoms like locking or catching.
- Damage in the avascular region of the meniscus (the “white zone”), where natural healing is unlikely.
- Persistent symptoms that do not respond to non-surgical treatments, including physiotherapy or anti-inflammatory medications.
The primary goal of the procedure is to relieve pain, restore mobility, and enhance knee function.
Preparation for Surgery
Prior to surgery, Dr Ben McGrath will conduct a comprehensive consultation and order imaging studies such as X-rays or MRIs to assess the extent of meniscal damage.
Key Steps in Preparation:
- Pre-Surgical Consultations: Dr McGrath will explain the procedure, potential risks, and benefits, and address any questions.
- Pre-Surgical Instructions: Patients may need to fast before surgery and adjust or stop certain medications, such as blood thinners, as directed.
- Lifestyle Adjustments: Weight management, smoking cessation, and pre-surgical strengthening exercises can improve recovery and outcomes.
What Happens During the Surgery?
Arthroscopic meniscectomy is performed as a day procedure under general or regional anaesthesia.
Surgical Steps:
- Incisions: Small incisions are made around the knee to insert an arthroscope (a thin camera) and surgical instruments.
- Visualisation: The arthroscope provides a magnified view of the joint, allowing Dr McGrath to assess the damage and guide the procedure.
- Tissue Removal: The damaged portion of the meniscus is carefully removed, and the remaining edges are smoothed to prevent irritation or further damage.
- Closure: Once the procedure is complete, the incisions are closed with sutures or adhesive strips, and the knee is bandaged.
The procedure usually takes 30 to 60 minutes, depending on the complexity of the damage.
Understanding the Risks
While arthroscopic meniscectomy is generally a safe procedure, it is important to understand potential risks, which include:
- Infection: At the incision sites or within the joint.
- Swelling and Stiffness: Temporary inflammation in the knee.
- Blood Clots: Rare but possible in the lower legs.
- Nerve or Vessel Injury: Extremely rare but a potential risk with any surgery.
Dr McGrath adheres to rigorous safety protocols to minimise risks and ensure patient safety.
What to Expect After Surgery
Immediate Post-Operative Care:
- Pain Management: Mild discomfort and swelling are expected and can be managed with prescribed medication and regular icing.
- Assistive Devices: Crutches may be used for additional support during the initial recovery period.
- Discharge Instructions: Patients will receive detailed instructions on wound care, activity restrictions, and follow-up appointments.
Most patients can begin bearing weight on the knee shortly after surgery, but specific recommendations will vary.
Rehabilitation and Recovery
Recovery from arthroscopic meniscectomy follows a structured rehabilitation program tailored to the patient’s needs:
Phase 1: Acute Phase (Days 1–7)
- Focus: Reduce swelling, restore range of motion (ROM), and re-establish muscle activity.
- Activities: Cryotherapy, quadriceps exercises, and gentle stretching.
Phase 2: Strength and Function (Days 10–Week 4)
- Focus: Regain strength and ROM, prepare for functional activities.
- Activities: Cycling, lunges, light leg presses, and balance training..
Phase 3: Advanced Activity (Weeks 4–7)
- Focus: Enhance strength, maintain ROM, and prepare for return to sports or active routines.
- Activities: Plyometric exercises, running drills, and agility training(post-meniscal-guidelines).
Long-Term Outcomes
Arthroscopic meniscectomy may help relieve pain, improve knee stability, and restore mobility, enabling patients to resume daily and physical activities. Long-term success depends on:
- Adherence to rehabilitation protocols.
- Regular follow-ups with Dr McGrath to monitor progress.
- Maintaining a healthy lifestyle to support knee joint health.
While the procedure is effective for many, the longevity of results may vary depending on the extent of damage, activity levels, and underlying joint conditions.
