Pearls and Pitfalls With Percutaneous Outside-In MCL Release by Finding the Magic Point During Arthroscopic Medial Meniscus Surgery

Pearls	Pitfalls
Draw a straight line from the posterior tibial cortex to the adductor tubercle.	Iatrogenic injury to articular cartilage, rarely medial meniscus and saphenous structures.
A single, bold puncture is needed approximately 1.2 cm above the joint line on this line.	Complete release of the MCL with multiple punctures.
Visible or palpable click or cracking sound occurs, indicating the release of MCL.
Measure the medial joint space before and after the release.
Less chance of meniscus injury, as the magic point is well above the joint line.
