The inner and outer meniscus serve to buffer the load and stabilise the joint. Damage to the meniscus can occur due to accidents, or wear and tear, or a combination of both. The consequences are pain, swelling, and possibly also entrapment. Meniscus damage occurs most frequently between the ages of 30 and 50. Men are affected twice as often as women (9 to 4.2/10000 respectively). If the damage is symptomatic, it can be repaired minimally-invasively by arthroscopy. The follow-up treatment depends on whether parts of the meniscus were removed (pain-adapted full weight-bearing) or whether the meniscus was sutured (usually partial weight-bearing). Unfortunately, only a few meniscus tears are suitable for suturing.
