Arthroscopic Osteophyte Removal (Knee)
A minimally invasive procedure to remove bone spurs causing knee pain and limited mobility
Knee arthroscopy for osteophyte removal involves the use of an arthroscope (a small camera) and specialised surgical instruments to access and remove excess bony growths within the knee joint. This procedure is commonly recommended for:
- Pain and discomfort caused by osteophytes impinging on surrounding tissues or structures.
- Reduced mobility and stiffness in the knee joint.
- Mechanical symptoms, such as locking or catching of the joint during movement.
The primary goals of this procedure are to relieve symptoms, enhance joint function, and reduce the risk of further complications.
Preparation for Surgery
Preparation for knee arthroscopy begins with a comprehensive consultation and imaging studies, such as X-rays, MRIs, or CT scans, to confirm the presence and location of osteophytes.
Key Steps in Preparation:
- Consultation: Dr Ben McGrath will review your symptoms, medical history, and imaging results to determine if osteophyte removal is appropriate.
- Pre-Surgical Instructions: Patients may need to fast before surgery and may be advised to stop certain medications, such as blood thinners.
- Lifestyle Adjustments: Improving overall health through smoking cessation, weight management, or strengthening exercises may optimise recovery and surgical outcomes.
What Happens During the Surgery?
Knee arthroscopy for osteophyte removal is typically performed as a minimally invasive day procedure under general or regional anaesthesia.
Surgical Steps:
- Incisions: Small incisions are made around the knee to insert the arthroscope and surgical instruments.
- Visualisation: The arthroscope provides a detailed view of the knee joint, enabling Dr McGrath to precisely locate the osteophytes.
- Osteophyte Removal: Specialised tools are used to carefully remove the bony growths without affecting healthy structures.
- Closure: Once the procedure is complete, the instruments are removed, and the incisions are closed with sutures or adhesive strips. The knee is bandaged to protect the area.
The procedure generally takes 30 to 60 minutes, depending on the size and location of the osteophytes.
Understanding the Risks
While knee arthroscopy for osteophyte removal is a safe and well-tolerated procedure, it is important to be aware of potential risks, including:
- Infection: At the incision sites or within the joint.
- Swelling or Stiffness: Temporary inflammation in the knee.
- Blood Clots: Rare but possible in the lower legs.
- Nerve or Vessel Damage: Extremely rare but a possible complication in any surgery.
Dr McGrath employs advanced surgical techniques to minimise these risks and ensure patient safety.
What to Expect After Surgery
Immediate Post-Operative Care:
- Pain Management: Mild pain and swelling are common and can be managed with prescribed medication and regular icing.
- Assistive Devices: Crutches or a knee brace may be recommended for support during initial recovery.
- Discharge Instructions: Patients will receive detailed guidance on caring for the incision sites, activity restrictions, and follow-up appointments.
Most patients can bear weight on the affected leg shortly after surgery, although this varies based on individual cases.
Rehabilitation and Recovery
Recovery timelines for osteophyte removal via knee arthroscopy typically follow these milestones:
- First Week: Gentle exercises may be introduced to maintain flexibility and prevent stiffness.
- 2 to 4 Weeks: Patients can gradually resume light daily activities, and physiotherapy may begin to strengthen the muscles around the knee.
- 6 to 12 Weeks: Many patients return to work and light physical activities, while high-impact exercises are generally avoided during this time.
Physiotherapy is essential in helping to restore mobility, strengthen the joint, and prevent recurrence of symptoms.
Long-Term Outcomes
Osteophyte removal through knee arthroscopy may help alleviate pain, improve joint function, and enhance mobility. Long-term success depends on:
- Adherence to post-operative and rehabilitation guidelines.
- Maintaining a healthy lifestyle, including regular low-impact exercise and weight management.
- Regular follow-up care with Dr McGrath to monitor progress and address any concerns.
While the procedure can provide lasting relief, ongoing care and attention to joint health are important to maintain results and minimise the risk of future issues.
