Arthroscopic approach

Make a 5 mm stab incision and insert the arthroscopic shaft carefully, so as not to damage the intraarticular cartilage surface.

Make a 5 mm stab incision and insert the arthroscopic shaft carefully, so as not to damage the intraarticular cartilage surface.

Next, remove the trocar and insert the arthroscope.

Irrigate the knee joint cavity until clear visibility is achieved.

Continuous positive pressure pump irrigation is essential, in order to prevent continuous bleeding, maintaining a pressure of 50-60 mmHg. High flow rates are required and adrenaline may be added to the saline for vasoconstriction.

The arthroscopic approach always requires that a full intraarticular examination of the knee joint is done, in order to avoid missing meniscal tears and ligament injuries, as well as osteochondral flake fractures.
