Although most frequent in the foot and ankle, knee involvement occurs occasionally with rapid, disabling progression. Diagnosis is often challenging due to overlap with septic and inflammatory arthritis. We report a woman in her forties with post-spinal anaesthesia neuropathy who developed progressive left knee pain, deformity and instability over 5 years. Radiographs and MRI confirmed Charcot arthropathy. She successfully underwent total knee arthroplasty (TKA) using a tibial stem and autologous bone grafting. At 2 years postoperatively, she achieved pain-free mobility, excellent function and radiographic implant stability. This case highlights diagnostic considerations and underscores TKA as a viable reconstructive option in selected patients.<\/jats:p>","DOI":"10.1136\/bcr-2025-269285","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T12:30:15Z","timestamp":1786105815000},"page":"e269285","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Charcot arthropathy of the knee managed with total knee arthroplasty"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2967-1828","authenticated-orcid":false,"given":"Abhijith","family":"K Jayan","sequence":"first","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, Odisha, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-3339-2744","authenticated-orcid":false,"given":"Mainak","family":"Roy","sequence":"additional","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9497-9624","authenticated-orcid":false,"given":"Bishnu Prasad","family":"Patro","sequence":"additional","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, Odisha, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kumar","family":"Asutosh","sequence":"additional","affiliation":[{"name":"Orthopaedics, Rangaraya Medical College, Kakinada, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"key":"2026080705300428000_19.8.e269285.1","doi-asserted-by":"crossref","first-page":"501","DOI":"10.1186\/s12891-019-2873-9","article-title":"Charcot neuroarthropathy of the knee due to idiopathic sensory peripheral neuropathy","volume":"20","author":"Yang","year":"2019","journal-title":"BMC Musculoskelet Disord"},{"key":"2026080705300428000_19.8.e269285.2","first-page":"100239","article-title":"An overview of Charcot\u2019s neuroarthropathy","volume":"22","author":"Dardari","year":"2020","journal-title":"J Clin Transl Endocrinol"},{"key":"2026080705300428000_19.8.e269285.3","doi-asserted-by":"crossref","first-page":"40","DOI":"10.4103\/2319-2585.125045","article-title":"A unusual presentation of syringomyelia as neuropathic arthropathy of elbow joint and review of literature","volume":"1","author":"Dwidmuthe","year":"2013","journal-title":"J Orthop Allied Sci"},{"key":"2026080705300428000_19.8.e269285.4","doi-asserted-by":"crossref","first-page":"1155","DOI":"10.1302\/0301-620X.98B9.37038","article-title":"The Charcot foot: pathophysiology, diagnosis and classification","volume":"98-B","author":"Trieb","year":"2016","journal-title":"Bone Joint J"},{"key":"2026080705300428000_19.8.e269285.5","doi-asserted-by":"crossref","first-page":"1","DOI":"10.21608\/bjas.2020.135485","article-title":"Management of Charcot Arthropathy of ankle and foot","volume":"5","author":"Elmorsy","year":"2020","journal-title":"Benha J Appl Sci"},{"key":"2026080705300428000_19.8.e269285.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.hcl.2013.04.002"},{"key":"2026080705300428000_19.8.e269285.7","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1186\/s13244-019-0768-9","article-title":"The Charcot foot: a pictorial review","volume":"10","author":"Rosskopf","year":"2019","journal-title":"Insights Imaging"},{"key":"2026080705300428000_19.8.e269285.8","unstructured":"Carlo C , Cazzaniga C , Manzini B , et al .
