Editorial Commentary: We Should Be Cautious About Using Catching and Locking as an Indication for Knee Arthroscopy: Mechanical Symptoms May Be Multifactorial in Their Causes.

Knee arthroscopy may be offered as a treatment for mechanical (catching/locking, grinding/clicking) and meniscal (pain with twisting/pivoting) symptoms. Recent studies have found that mechanical symptoms, particularly catching/locking, may be multifactorial in their causes (chondral lesions, meniscal tears, loose bodies) and less responsive to arthroscopic meniscectomy. Surgeons should be aware of this evidence and adjust their surgical indications appropriately.
