Abstract

Purpose The all-inside arthroscopic modified Broström operation has been developed for lateral ankle instability. We compared the biomechanical parameters of the all-inside arthroscopic procedure to the open modified Broström operation. Methods Eleven matched pairs of human cadaver specimens [average age 71.5 (range 58-98) years] were subject to the arthroscopic modified Broström operation using a suture anchor and the open modified Broström operation. The ligaments were loaded cyclically 20 times and then tested to failure. Torque to failure, degrees to failure, and stiffness were measured. A matched-pair analysis was performed. Results There was no significant difference in torque to failure between the open and arthroscopic modified Broström operation (19.9 ± 8.9 vs. 23.3 ± 12.1 Nm, n.s). The degrees to failure did not differ significantly between the open and arthroscopic modified Broström operations (46.8 ± 9.9° vs. 46.7 ± 7.6°, n.s). The working construct stiffness (or stiffness to failure) was no significant difference in the two groups (0.438 ± 0.21 vs. 0.487 ± 0.268 Nm/deg for the open and arthroscopic modified Broström operations, respectively, n.s). Conclusion The all-inside arthroscopic modified Broström operation and the open modified Broström operation resulted in no significantly different torque to failure, degrees to failure, and working construct stiffness with no significant differences (n.s, n.s, and n.s, respectively). Our results indicate that the arthroscopic modified Broström operation is a reasonable alternative procedure for chronic ankle instability.
