Arthroscopic approach

Principles

The arthroscopic approach is only recommended in minimally, or nondisplaced, fractures in young patients. Advanced experience in arthroscopic surgery is essential.


Identify the lateral soft spot adjacent to the patellar tendon. enlarge

Anterolateral port

Identify the lateral soft spot adjacent to the patellar tendon.


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

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.


Identify the medial soft spot adjacent to the patellar tendon and palpate under arthroscopic control. enlarge

Anteromedial port

Identify the medial soft spot adjacent to the patellar tendon and palpate under arthroscopic control.


Make a 5 mm stab incision and insert the arthroscopic hook through the incision. enlarge

Make a 5 mm stab incision and insert the arthroscopic hook.


After removal of the arthroscope, insert a suction drain through the arthroscopic shaft. enlarge

Wound closure

After removal of the arthroscope, insert a suction drain through the arthroscopic shaft.

Close the skin incisions with sutures in a routine manner.
