This presentation gives a high level of detail about routine knee arthroscopy, using a pump and a 30 degree scope. In addition a lateral meniscal repair is described using Smith and Nephew’s FastFix 360 system and coblation of the retropatellar articular cartilage.
Coblation is a technique that uses radio-frequency to create highly-energised particular vibration to stabilise articular cartilage and prevent fissuring of the joint surface. It also serves to stop small cartilage fragments from “flaking off” are causing a reactive effusion.
The blood supply of the meniscus reaches the peripheral 1/3, which is known as the “red-zone”. Tears within this zone are known as red-on-red tears, where both sides of the tear are vascular. Red-on-white tears are on the periphery of this vascular zone.
Tears can only be repaired if they are not deformed and easily reducible. Typically long bucket-handle tears that are reasonably fresh (<3 months) are most suitable for repair.
Traumatic tears are more suitable for repair than degenerative type tears.
