An Analysis of Outcomes after Use of the Maxwell-Brancheau Arthroereisis Implant

The authors present a retrospective study of 35 consecutive patients (60 feet) treated with the Maxwell-Brancheau Arthroereisis (MBA) implant. The mean age of the cohort at the time of surgery was 14.3 (range 5 to 46) years, and 22 (62.86%) men and 13 (37.14%) women were included. Preoperative and postoperative anteroposterior and lateral foot radiographs were compared at a mean of 36 (range 18 to 48) months postoperatively, and the following mean changes were reported: talocalcaneal angle 24.15 degrees +/- 7.97 degrees to 18.53 degrees +/- 8.23 degrees, calcaneocuboid angle 18.67 degrees +/- 8.72 degrees to 11.76 degrees +/- 8.49 degrees, first to second intermetatarsal angle 9.42 degrees +/- 2.67 degrees to 7.61 degrees +/- 2.69 degrees, calcaneal inclination angle 11.93 degrees +/- 6 degrees to 14.93 degrees +/- 5.85 degrees, and talar declination angle 34.0 degrees +/- 8.59 degrees to 28.02 degrees +/- 6.85 degrees; all of these differences were statistically significant (p < .0001). A subgroup of 24 (68.57%) patients also answered a subjective questionnaire at a mean of 33 (range 12 to 55) months postoperatively. The presenting chief complaints were resolved in 23 patients (95.83%) of the subgroup, and 21 patients (87.5%) returned postoperatively to either the same or a greater activity level in sports. Twenty-three (95.83% of the subgroup) patients said they were 75% to 100% satisfied with their surgical outcome, and that they would recommend the surgery to a friend or family member with the same condition, whereas 1 (4.17%) claimed 0% satisfaction after placement of inappropriately sized implants (which were later replaced to the patient's clinical satisfaction) in both feet.
