While the incidence of TTS following a total knee replacement (TKR) could not be found, we present the case of a 78-year-old white female who developed symptoms of TTS 2 weeks after a left knee replacement. The history, examination, imaging, and electrodiagnostic (EDX) studies were consistent with the diagnosis of left-sided TTS. After a course of conservative care failed to alleviate her symptoms, the patient underwent nerve decompression surgery for the affected nerves. Her pain score prior to the surgery was 5 out of 10 when walking, and 10 out of 10 at night. Immediately after surgery, her pain at its worst was 3 out of 10, and soon thereafter she reported no pain whatsoever (0 out of 10). All TTS-related symptoms subsequently resolved. This case presents an unusual extrinsic cause of TTS, highlights the need for a thorough history when diagnosing TTS, and contributes to the scientific community\u2019s knowledge of knee complications and possible etiologies of TTS.<\/jats:p>","DOI":"10.7547\/24-021","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T10:07:17Z","timestamp":1745575637000},"source":"Crossref","is-referenced-by-count":0,"title":["Tarsal Tunnel Syndrome Following a Total Knee Replacement"],"prefix":"10.3390","volume":"115","author":[{"given":"Michael S.","family":"Nirenberg","sequence":"first","affiliation":[{"name":"Friendly Foot Care, PC, Crowne Point, IN."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto P.","family":"Segura","sequence":"additional","affiliation":[{"name":"Chicago Peripheral Nerve Center, Chicago, IL."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","reference":[{"key":"B1","series-title":"J Bone Joint Surg","first-page":"180","article-title":"The tarsal-tunnel syndrome","volume":"44","author":"Keck CS","year":"1962","unstructured":"Keck CS: The tarsal-tunnel syndrome.
