Our aim in this study was to determine the frequency of symptomatic spinal stenosis in patients who underwent total knee arthroplasty. A total of 156 patients who underwent total knee arthroplasty in Antalya Training and Research Hospital between 2014-2017 were included. Among the patients, 126 were female, 30 were male, and mean age of the study group was 67.22 (SD 6.6). These patients were retrospectively evaluated and the frequency of spinal stenosis was investigated. Among our patients, 104 (66.7%) had received unilateral, and 52 (33.3%) had received bilateral total knee arthroplasty. Spinal stenosis was identified in 26 (16.7%) patients. Three of these patients underwent surgical treatment, while the remaining 23 were treated conservatively. It should be kept in mind that patients who are to receive total knee arthroplasty may concurrently have spinal stenosis, so patient history should be carefully taken and detailed physical examination should be performed.
