Knee Arthroscopy | PAX Medicus Medical Tourism UK

Knee Arthroscopy

Knee arthroscopy is a modern minimally invasive procedure used to diagnose and treat knee problems such as meniscal tears, cartilage damage, ligament injuries, and recurrent swelling or instability. Through partner orthopaedic centres, Pax Medicus coordinates high-quality diagnostic arthroscopy and therapeutic knee procedures for patients requiring precise assessment and treatment.

What Is Knee Arthroscopy?

Knee arthroscopy is a minimally invasive surgical technique performed through very small incisions (usually 2–3 portals, 8 mm in size). A camera and fine surgical instruments allow the surgeon to inspect and treat the joint with exceptional precision.

  • Used for both diagnosis and treatment.
  • Low-trauma procedure with small scars.
  • Helps restore joint mobility and stability.

Contraindications

Knee arthroscopy is not recommended in certain situations, including:

  • Advanced osteoarthritis requiring knee replacement.
  • Conditions that improve with conservative treatment.
  • Obesity that increases surgical risk.
  • Active cancer treatment or severe systemic illness.

Indications for Knee Arthroscopy

Arthroscopy is recommended when knee pain, swelling, locking, or instability persists despite conservative treatment, or when internal damage is suspected.

Common medical indications

  • Meniscal tears or delamination.
  • Chondral and osteochondral defects.
  • Synovial fold hypertrophy.
  • Periarticular cysts.

Trauma-related reasons

  • Acute injury causing knee locking.
  • Intra-articular fractures.
  • Ligament damage (ACL, PCL, MCL, LCL).
  • Foreign bodies inside the joint.

Degenerative & inflammatory causes

  • Chondromalacia (cartilage wear).
  • Post-traumatic changes.
  • Rheumatoid arthritis-related damage.

Arthroscopy may also be used when MRI results are unclear and a direct- minimally invasive- visual assessment of the joint is required.

How Knee Arthroscopy Is Performed

The procedure is usually performed under spinal anaesthesia, though general anaesthesia may be used in selected cases. The surgeon inserts a camera and instruments into the joint through small incisions, enabling precise treatment.

Meniscus procedures

  • Partial or complete meniscectomy.
  • Meniscus repair or suturing.
  • Implant-based meniscus fixation.

Ligament procedures

  • Repair of torn ligaments or capsule.
  • ACL, PCL, MCL or LCL reconstruction.
  • Graft replacement using tendon or synthetic material.

Cartilage procedures

  • Cartilage repair or regeneration techniques.
  • Treatment of chondral or osteochondral lesions

Most arthroscopies take 30–120 minutes, depending on the complexity and the number of structures requiring repair.

Although knee arthroscopy is considered a safe procedure, complications may occur in a small percentage of cases:

  • Bleeding or haematoma within the joint.
  • Infection at the surgical site.
  • Nerve irritation or temporary numbness.
  • Persistent swelling or joint effusion.
  • Venous thrombosis (higher risk in obese or cardiac patients).

Most patients return home the same day or the following morning. Recovery depends on the scope of the procedure and typically lasts 6–12 weeks.

  • Crutches recommended for the first weeks.
  • Early physiotherapy is essential.
  • Nerve irritation or temporary numbness.
  • Strengthening and stretching exercises restore mobility.
  • Gradual return to sport once stability and strength improve.

  • Minimally invasive approach with tiny scars.
  • Less postoperative pain compared to open surgery.
  • Quick recovery and earlier return to activity.
  • Precise diagnosis and treatment in one session.
  • Improved joint stability and mobility.
