    Does measuring the medial gap before bone resection in total knee arthroplasty provide optimum gap adjustment and prevent bone recutting?
    (Acta Medica Belgica, 2023) Tiftikci, U.; Serbest, S.; Kaya, O.; Keskinkilic, S. I.; Kilinc, C. Y.; Firat, A.
    This study aimed to demonstrate that measuring the medial gap before bone resection during total knee arthroplasty (TKA) provides an optimum gap adjustment in varus knees. In this study, patients were separated into two groups. Group 1 included patients whose medial joint gap was measured before bone resection and Group 2 included patients who underwent conventional technique without measuring. The medial joint gap was measured with a custom-made gap measuring device up to the point that the knee was corrected and aligned along its mechanical axis. Medial joint gap distances, distal medial femoral bone cut thicknesses, amounts of tibial resection calculated; gap internal distances measured after cutting and the thicknesses of the trial inserts were recorded. A comparison was made between the groups concerning the number of patients requiring an additional tibial bone cut and the distribution of insert thicknesses. Extra tibial bone resections were performed in two (5.7%) patients in Group 1 and 10 (28.6%) patients in Group 2. In Group 1, where the medial joint gap was measured, the need for an additional bone resection was statistically less (p=0.018). In comparing the distribution of insert size by group, the number of patients on whom an 8 mm insert had been used was significantly greater in Group 1 (p=0.024). The findings obtained in this study suggest that measuring the medial joint gap before bone resection in total knee arthroplasty may prevent repeated bone recutting and additional bone resections.

    Is epineurectomy necessary in the surgical management of carpal tunnel syndrome?
    (Medknow Publications & Media Pvt Ltd, 2017) Tiftikci, U.; Serbest, S.
    Background: In this study, it was aimed to determine whether median nerve epineurectomy is beneficial in the surgical management of carpal tunnel syndrome (CTS). Materials and Methods: The study enrolled 72 patients including 34 patients without epineurectomy (Group A) and 38 patients with epineurectomy (Group B). Surgery was performed in patients with severe electrodiagnostic CTS findings, CTS duration >1 year and flattening along with hypervascularization in median nerve. All patients were assessed by visual analog scale, two-point discrimination test as well as subjective and objective findings at baseline and on the months 1, 3, and 6 after surgery. Results: The mean age was 58.3 years (42-75 years) in 38 patients who underwent an epineurectomy, whereas it was 61.5 years (41-82 years) in 34 patients who did not have an epineurectomy. The groups were similar with regard to age, gender, duration of symptoms, and preoperative physical findings. Mean visual analog scale (VAS) scores were 1.7 in Group A and 1.8 in Group B. Again, these differences were not significant, on physical examination, the average two-point discrimination in the distribution of the median nerve was 4.9 mm (range: 3-11 mm) in Group A and 5.3 mm (range: 3-10 mm) in Group B. In postoperative evaluations, there was a better improvement in visual analog scale scores, two-point discrimination test and subjective symptoms including dysesthesia, pain and nocturnal pain within first 3 months; however, there was no marked difference in objective and subjective findings on the 6th month. No complication or recurrence was observed. Conclusion: We believe that median nerve epineurectomy is unnecessary in the surgical management of primary CTS since it has no influence on the midterm outcomes.
