Knee arthroscopy is a minimally invasive surgery that allows injuries inside the joint to be diagnosed and treated through small incisions. It is particularly useful for certain meniscal injuries, aiming to preserve as much healthy tissue as possible, relieve symptoms and restore knee function.
During arthroscopy a small camera is introduced into the knee, allowing the structures of the joint to be seen directly. Specialized instruments are used through additional small incisions to treat the injury.
When the characteristics of the tear allow it, the meniscus is repaired or sutured in order to preserve it and encourage healing. In cases where repair is not possible, it may be necessary to remove only the damaged portion of the meniscus, preserving as much healthy tissue as possible.
24 hours
2 days to 1 week
MRI without contrast
It may be considered in patients with:
Arthroscopy is not indicated for every knee pain or every meniscal injury. In patients with advanced joint wear (osteoarthritis), degenerative injuries without relevant mechanical symptoms, or other causes of pain, more appropriate treatments may exist.
The decision to perform an arthroscopy is made after a specialist evaluation, considering symptoms, physical examination, imaging studies, the type of injury and the needs of each patient.
Usually 24 hours for most day-to-day functions.
If you live and work outside the country, at least 2 days is recommended if you have doctors in your area. Otherwise, at least a week, so the stitches can be removed.
Ideally an MRI without contrast.
