If a meniscal cartilage is injured, typically during a twisting injury, and the patient suffers from pain or instability then the cartilage will require treatment. If the injury is not fresh the tear may not be repairable and may need removing.
Two keyhole incisions are made in the front of the knee so that a telescope (arthroscope) and tools can be introduced into the knee. The tools may be mechanical, electrical or use high frequency energy to remove tissue and frequently a combination of tools will be required. No stitches are required.
Following surgery the patient goes to physiotherapy and generally returns to work between 2 and 6 weeks later dependent on the nature of the job.
