The menisci (popularly known as cartilages) are the structures on which most of the work is carried out upon in arthroscopy. The menisci are crucial to knee function both in bending and flexing and in twisting or pivoting, acting as a washer or shock absorber within the joint to allow smooth movement of the femur upon the tibia.

The menisci can be injured by sudden trauma such as a sporting accident or a twisting injury or alternatively the menisci may tear as a result of minor repetitive injury especially in an older patient. Once a meniscus is torn, the damaged edge causes pain, particularly when you try to carry out a deep knee bend or twisting movement. As well as pain, some long term damage can occur as a result of the torn cartilage damaging the bearing surface of the joint.

Meniscal surgery to a damaged articular cartilage is carried out by removing the area which is torn, whilst leaving the vast majority of undamaged meniscus intact. This lessens the chance of developing premature osteoarthritic degeneration of the knee. Meniscal damage that involves a large surface area of the structure can easily be repaired.

Frequently Asked Questions

Joint replacements – what type of artificial implant does Mr Moss use?

Mr Moss uses a range of artificial implants, or prostheses, to replace diseased or damaged bone around joints. The implants mimic bone shape and can be made of metal, high density polyethylene or ceramic. They are made by Zimmer, the largest orthopaedic manufacturing company in the world.

Mr Moss is frequently used as a specialist advisor to Zimmer and works extremely closely with the prostheses manufacturer to develop some ground breaking products in the United Kingdom. Working this closely with Zimmer, Mr Moss has been able to successfully carry out some of the UK’s firsts for his patients.
