Foot and/or ankle problems following limb alignment changes in uni-compartmental knee arthroplasty

Objective Foot and/or ankle (F/A) problems may be encountered in medial uni-compartmental knee (UKA) patients postoperatively due to the limb alignment changes and alterations weight bearing of F/A. This study aimed evaluate risk factors incidence foot arthroplasty patients. Methods Patients who underwent UKA between 2016 2019 our clinic were evaluated presence F/A was recorded. Radiologic evaluations included hip angle (HKA), proximal tibial angle, posterior slope talar tilt inclination, dome mechanical axis (TDMA), talocrural (TCA) measured on preoperative follow-up long-leg standing radiographs. The range motion, Q angles, muscle strengths measured. Visual analog scale, physical performance limitations, patient-reported activity limitations for all with reported additionally Functional Index. Results Forty-four (38 female, 6 male; mean age 58.66 ± 8.6 years; BMI 31.30 3.81, period 34.22 18.95 months) study. There 13 (29.5%) problems. Postoperative comparison without showed statistically significant differences only WOMAC SF12 health sub-scores ( p = 0.002, 0.003, respectively). no postoperative change TDMA > 0.05) contrast 0.006). difference TCA measurements groups 0.79). Comparison radiologic demonstrated HKA (−2.82 2.53 vs. −0.80 3.12, 0.033). Conclusion adversely affecting functional status frequent cohort residual varus deformity a factor this. Therefore, if slight is at patients, should evaluated.
