Self-reported questionnaires and performance-based tests are tools commonly used for measuring physical function. OBJECTIVES: (1) To evaluate the impact of end-stage knee OA on functional outcomes and examine the association between self-reported and performance-based measures of function in patients with end-stage knee osteoarthritis awaiting total knee arthroplasty (2) To explore the interrelationships among pain, strength, and overall physical function in this patient population. METHODS: In this cross-sectional analysis, 33 patients with end-stage knee OA were recruited and completed the knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS) and executed performance-based tests including the Timed Up and Go, the 30-second chair stand test, and the Stair Climbing Test. Knee pain, and isometric hip and knee strength were evaluated. RESULTS: Patients perceived deficits in their physical functionwith a score of 35\/100 on the KOS-ADLS and demonstrated functional limitations in all performed tasks. KOS-ADLs was weakly associated with TUG and 30s-CST (r=-0.301, p= 0.047, and r= 0.39, p= 0.014. respectively). Knee pain was linked with the KOS-ADL score and GRS score (r=-0.406, p= 0.010; r=-0.343, p= 0.027; respectively), while the strength of the affected side was correlated with the performed (p=&lt; 0.001) and reported function outcomes (p= 0.007). CONCLUSION: Participants exhibit declines in both perceived and executed functional abilities. Self-reported and performance-based functional measures are weakly correlated within our study group, highlighting the importance of incorporating both measures in clinical practice for a comprehensive evaluation of physical function. Pain was linked to subjective aspect of physical function, while strength was connected to perceived and performed functional capacity. Implementing a tailored rehabilitation program targeting muscle weakness and pain holds the potential to mitigate functional decline in individuals awaiting total knee arthroplasty (TKA).<\/jats:p>","DOI":"10.3233\/bmr-230256","type":"journal-article","created":{"date-parts":[[2024,1,16]],"date-time":"2024-01-16T11:03:54Z","timestamp":1705403034000},"page":"997-1006","source":"Crossref","is-referenced-by-count":6,"title":["Physical functioning in patients with end-stage knee osteoarthritis: A cross-sectional study in Jordan using self-reported questionnaire and performance-based tests"],"prefix":"10.1177","volume":"37","author":[{"given":"Sumayeh","family":"Abujaber","sequence":"first","affiliation":[{"name":"Department of Physiotherapy, School of Rehabilitation Sciences, The University of Jordan, Amman, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Altubasi","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, School of Rehabilitation Sciences, The University of Jordan, Amman, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Hamdan","sequence":"additional","affiliation":[{"name":"Department of Special Surgery, Division of Orthopaedics, School of Medicine, The University of Jordan, Amman, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raed","family":"Al-Zaben","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Royal Medical Services, Amman, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar","family":"Bani-Ahmad","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Royal Medical Services, Amman, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"key":"10.3233\/BMR-230256_ref1","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1016\/j.joca.2021.04.020","article-title":"Epidemiology of osteoarthritis","volume":"30","author":"Allen","year":"2022","journal-title":"Osteoarthr Cartil."},{"key":"10.3233\/BMR-230256_ref2","doi-asserted-by":"crossref","unstructured":"Murphy L, Schwartz TA, Helmick CG, et al.
