I am having a knee arthroscopy. How long does it usually take?

Diagnosis dependent. Arthroscopy of the knee can take anywhere from 10 minutes to several hours depending upon the diagnosis and planned surgical intervention. A simple meniscal tear debridement can be very rapid, whereas a meniscal repair combined with a ligament reconstruction can take well over an hour. Your surgeon will give you the most accurate timetable specific to your knee and planned surgery.
30-45 minutes. The actual surgery takes 30-45 minutes depending on the procedure, but could take longer for ligament, meniscal or cartilage repair.
Knee arthroscopy . A typical knee scope can be performed in 45 minutes to an hour. Acl surgery and articular cartilage transfers can take up to 2 hours.
