Meniscal Repair Surgery
A surgical procedure to repair and preserve the damaged meniscus in the knee
The meniscus is a crescent-shaped cartilage in the knee that absorbs shock and stabilises the joint. Tears can result from injuries, repetitive stress, or degenerative conditions.
Meniscal repair surgery is often recommended for
- Tears in the vascular region of the meniscus (the “red zone”), where there is a greater potential for healing.
- Younger or active individuals who wish to maintain knee functionality and reduce the risk of future issues.
- Persistent symptoms, such as pain, swelling, or instability, unresponsive to non-surgical treatment.
The primary goal of meniscal repair surgery is to restore the meniscus’ natural structure and functionality, alleviate symptoms, and support long-term joint health.
Preparation for Surgery
Preparation includes a thorough evaluation by Dr Ben McGrath, often involving imaging studies such as X-rays or MRIs to confirm the tear and determine its location and type.
Key Steps in Preparation:
- Consultation: Dr McGrath will explain the procedure, discuss risks and benefits, and answer any questions.
- Pre-Surgical Instructions: Patients may be asked to fast before the procedure and discontinue certain medications, such as blood thinners.
- Lifestyle Adjustments: Maintaining a healthy weight, engaging in pre-surgical exercises, and stopping smoking can optimise surgical outcomes.
What Happens During the Surgery?
Meniscal repair surgery is typically performed as an arthroscopic procedure under general or regional anaesthesia.
Surgical Steps:
- Incisions: Small incisions are made to insert an arthroscope (a thin camera) and surgical instruments.
- Visualisation: The arthroscope provides a magnified view of the knee joint, allowing Dr McGrath to assess the tear.
- Repair Technique: Sutures or specialised devices are used to reattach the torn edges of the meniscus to promote natural healing.
- Closure: The incisions are closed with sutures or adhesive strips, and the knee is bandaged.
The procedure generally takes 60 to 90 minutes, depending on the complexity of the tear.
Understanding the Risks
While meniscal repair surgery is considered safe, potential risks include:
- Infection: At the incision sites or within the joint.
- Swelling or Stiffness: Temporary inflammation in the knee.
- Failure to Heal: Some tears may not heal completely, necessitating further treatment.
- Blood Clots: Rare but possible in the lower limbs.
- Nerve or Vessel Injury: Extremely rare but a potential complication.
Dr McGrath follows stringent safety protocols to minimise these risks.
What to Expect After Surgery
Immediate Post-Operative Care:
- Pain Management: Mild discomfort and swelling are normal and can be managed with prescribed pain relief and icing.
- Weight-Bearing: Weight-bearing may be limited initially and gradually increased as directed.
- Assistive Devices: Crutches or a brace may be used for support and to protect the repair.
Discharge Instructions: Patients will receive clear guidance on wound care, activity restrictions, and follow-up appointments.
Rehabilitation and Recovery
Recovery from meniscal repair surgery follows a structured rehabilitation plan tailored to the individual’s needs:
Phase 1: Weeks 0–2
- Goals: Full range of motion (ROM) and reduced swelling.
- Activities: Cryotherapy, isometric quadriceps exercises, and straight leg raises (SLRs). Weight-bearing as tolerated.
Phase 2: Weeks 2–4
- Goals: Improved strength and normal gait.
- Activities: Closed kinetic chain resistance exercises, cycling, swimming, and early functional training.
Phase 3: Weeks 4–8
- Goals: Strength and functional capacity at 85% of the unaffected side.
- Activities: Advanced functional training, sport-specific progression, and discharge to full activity.
Long-Term Outcomes
Meniscal repair surgery may help restore knee stability and functionality, reduce pain, and minimise the risk of joint degeneration. Long-term success depends on:
- Adherence to rehabilitation protocols.
- Regular follow-up appointments to monitor progress.
- Maintaining a healthy lifestyle, including low-impact exercises to protect the joint.
Preserving the meniscus can offer significant benefits for joint health and overall mobility, particularly in active individuals.
