Abstract

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

Abstract

Objectives: This study aims to compare the effects of minimidvastus (MMV) versus medial parapatellar (MPP) approach on rapid recovery protocols during total knee arthroplasty (TKA). Patients and methods: This prospective, randomized, singleblinded study was performed in 54 patients (4 males, 50 females; mean age 64.1±6.4 years) diagnosed as primary knee osteoarthritis and planned for unilateral TKA between May 2018 and March 2019. Patients were randomly assigned as MMV (1 male, 26 females; mean age 65±6.4 years) and MPP (3 males, 24 females; mean age 63.2±6.3 years) groups. Rapid recovery TKA protocol and discharge criteria were assembled and all patients were evaluated preoperatively, and at postoperative first and third months. Length of hospital stay (LOS) was recorded for all patients. Hemoglobin and hematocrit values, radiologic assessment of alignment, knee range of motion (ROM), quadriceps muscle strength, Visual Analog Scale (VAS), 30-sec chair-stand test, stair-climb test, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Short Form-36 (SF-36) were used for evaluations by blinded observers. Results: There was no significant difference in demographic variables between two groups. Operative time in MMV Group (78.1±2.7 min) was significantly longer than the MPP Group (65.9±2.6 min) (p0.05). In terms of quadriceps muscle strength gain, we could not find any difference between groups in pre- and postoperative difference of changes (p>0.05). Conclusion: With the use of contemporary rapid recovery protocols during TKA, MMV approach had no superiority over MPP approach when quadriceps muscle strength, LOS, pain, function, and quality of life were assessed. Longer operative time in the MMV approach compared to MPP approach may be considered as a disadvantage.
