Pearls and Pitfalls

	Pearls and Pitfalls
Anterolateral portal	The ideal point is 45° anterior to the scapular axis, just over the biceps deflection, guided by an 18-gauge needle via an intra-articular view, with the scope in the posterior portal.
Anteroinferolateral portal	The ideal point is through the subscapularis tendon, near its insertion in the humerus, in line with the humeral head equator, guided by an 18-gauge needle via an intra-articular view, with the scope in the posterior portal.
Cutting LHB	An anteroinferolateral or anterior standard portal should be used. Cutting should not be performed too proximally and should be performed where the elliptical diameters seem to be more similar to those of the LHB.
Accessing superior portion of pectoralis tendon	The scope should be inserted in the anterolateral portal, in the subdeltoid space, in the direction of the pectoralis major insertion. A shaver should be carefully applied to the bursa; the LHB emerges from the bicipital tunnel under the superior portion of the pectoralis major, beneath the short head. Special care is needed for bleeding in this region because vessels can be close.
If bicipital tunnel extends distally	The tunnel needs to be opened in this area to pull the biceps tendon in this situation.
If biceps does not pass through tunnel	The entire tunnel needs to be opened in this situation.
Insertion point	This should be performed just after the LHB tendon is pulled out. The guidewire should be inserted just over the LHB, through the subscapularis split, with no cannula. The guidewire should be inserted just medial to the glenoid rim at the 3-o'clock position, similarly to anchor insertion. The hole should extend to the glenoid. A cannula should not be used.
Anchor insertion	Preference should be given to soft-tissue anchors once the space is small. A cannula should be used. If required by the surgeon, an anterior portal can also be made, but in our experience, this is not necessary.
