The aim of this study was to retrospectively analyze to compare radiological and clinical outcomes between spinal fusion only and preoperative TKA with spinal fusion for the patients with concurrent KOA and degenerative LSD. A total of 72 patients with concurrent KOA and degenerative LSDs who underwent spinal fusion at less than three levels were divided in two groups: non-TKA group (n = 50) and preoperative TKA group (n = 22). Preoperative lumbar lordosis (LL) was significantly lower in the preoperative TKA group than the non-TKA group (p &lt; 0.05). Significantly higher preoperative pelvic incidence (PI), PI\/LL mismatch, and pelvic tilt (PT) occurred in preoperative TKA group than non-TKA group (all p &lt; 0.05). There was significant improvement of postoperative Oswestry Disability Index and leg Visual Analog Scale in the preoperative TKA group (all p &lt; 0.01). Preoperative TKA could be a benefit for in proper correction of sagittal spinopelvic alignment by spinal fusion. Therefore, preoperative TKA could be considered a preceding surgical option for patients with severe sagittal spinopelvic parameters in concurrent KOA and degenerative LSD.<\/jats:p>","DOI":"10.3390\/jcm10194475","type":"journal-article","created":{"date-parts":[[2021,9,28]],"date-time":"2021-09-28T21:38:09Z","timestamp":1632865089000},"page":"4475","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Impact of Preoperative Total Knee Arthroplasty on Radiological and Clinical Outcomes of Spinal Fusion for Concurrent Knee Osteoarthritis and Degenerative Lumbar Spinal Diseases"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8162-9585","authenticated-orcid":false,"given":"Hong Jin","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Inje University Sanggye Paik Hospital, College of Medicine, Inje University, Seoul 01757, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6949-6954","authenticated-orcid":false,"given":"Jae Hyuk","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Korea University Guro Hospital, College of Medicine, Korea University, Seoul 08308, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6731-1063","authenticated-orcid":false,"given":"Dong-Gune","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Inje University Sanggye Paik Hospital, College of Medicine, Inje University, Seoul 01757, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Woo","family":"Suh","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Korea University Guro Hospital, College of Medicine, Korea University, Seoul 08308, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hoon","family":"Jo","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Inje University Sanggye Paik Hospital, College of Medicine, Inje University, Seoul 01757, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang-Il","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kwang-Sup","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Chung-Ang University Hospital, College of Medicine, Chung-Ang University, Seoul 06973, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5134-301X","authenticated-orcid":false,"given":"Woojin","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Albert Einstein College of Medicine, Montefiore Medical Center, Bronx, NY 10467, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1441","DOI":"10.1097\/01.brs.0000166503.37969.8a","article-title":"United States Trends in Lumbar Fusion Surgery for Degenerative Conditions","volume":"30","author":"Deyo","year":"2005","journal-title":"Spine"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"682","DOI":"10.31616\/asj.2020.0472","article-title":"Lumbar Spinal Stenosis: Pathophysiology and Treatment Principle: A Narrative Review","volume":"14","author":"Lee","year":"2020","journal-title":"Asian Spine J."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"886","DOI":"10.31616\/asj.2020.0568","article-title":"Adult Spinal Deformity: Current Concepts and Decision-Making Strategies for Management","volume":"14","author":"Kim","year":"2020","journal-title":"Asian Spine J."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"2039","DOI":"10.1016\/j.arth.2020.03.018","article-title":"Knee or Spine Surgery First?
