Outcomes After Rotator Cuff Repair With Transverse Scapular Ligament Release in Patients With Severe Fatty Degeneration of the Infraspinatus.

In patients with more FD in the infraspinatus than the supraspinatus muscle, TSL release appeared to have no benefit for cuff healing or FD reversal in cuff muscles. The possibility of suprascapular nerve entrapment remains in patients with more FD in the infraspinatus than the supraspinatus, and this potential nerve problem is not properly addressed by TSL release alone.
