We aimed to analyze the changes in isokinetic internal (
IR
) and external (
ER
) rotator muscles fatigue (a) in patients with non‐operated recurrent anterior instability, and (b) before and after shoulder surgical stabilization with the
B
ristow–
L
atarjet procedure. Thirty‐seven patients with non‐operated unilateral recurrent anterior post‐traumatic instability (
NG
) were compared with 12 healthy subjects [control group (
CG
)]. Twenty patients with operated recurrent anterior instability group (
OG
) underwent isokinetic evaluation before and 3, 6, and 21 months after
B
ristow–
L
atarjet surgery.
IR
and
ER
muscles strength was evaluated with
C
on‐
T
rex® dynamometer, with subjects seated and at a 45° shoulder abduction angle in scapular plane.
IR
and
ER
muscle fatigue was determined after 10 concentric repetitions at 180°·s
−1
through the fatigue index, the percent decrease in performance (
DP
), and the slope of peak torque decrease. There were no differences in rotator muscles fatigue between
NG
and
CG
. In
OG
, 3 months post‐surgery,
IR DP
of operated shoulder was significantly (
P
< 0.001) higher than presurgery and 6 and 21 months post‐surgery. Rotator muscles fatigability was not associated with recurrent anterior instability. After surgical stabilization, there was a significantly higher
IR
fatigability in the operated shoulder 3 months post‐surgery, followed by recovery evidenced 6 months post‐surgery and long‐term maintenance over 21 months.
