Objective: Knee osteoarthritis (OA) and related pain/impairment impacts patients’ physical and mental health. More radiographically severe knee OA is believed to respond less favorably to conservative treatments such as physical therapy (PT) but has not been correlated with PROMIS-10. This study aimed to compare baseline PROMIS-10 physical and mental health scores in patients undergoing PT for knee OA, sub-grouped by radiographic severity [Kellgren-Lawrence grade (KL)] and number of knee compartments involved, and describe the relationship between radiographic severity of knee OA and post-PT PROMIS-10 scores.
Design: Retrospective review
Setting: Orthopedic specialty hospital outpatient musculoskeletal clinics.
Participants: 109 patients (age≥18 years) presented for elective evaluation of knee OA from 04/01/2019 to 08/01/2021 and underwent PT, radiographs, and a follow-up.
Interventions: PT
Main Outcome Measures: PROMIS-10
Results: Subjects included 65 females and 44 males; average age was 66.6±10.0 years (range: 25-92). Baseline PROMIS-10 physical and mental health scores averaged 44.4±7.2 and 52.8±9.0. Post-PT PROMIS-10 physical and mental health scores averaged 44.7±6.7 and 52.6±8.7. Physical health scores improved in 39% of subjects; mental health scores improved in 36% of subjects. There was no relationship between post-PT PROMIS-10 scores and radiographic severity of knee OA. Females exhibited osteoarthritic changes in all compartments in 72% of cases compared to 55% of males (p=0.020). The medial compartment was predominantly affected for males (93%) and females (94%). Females demonstrated a higher predisposition for lateral compartment involvement (83%) than males (64%) (p=0.021). Additionally, females had a higher proportion of radiographic severe OA with a KL grade 3-4 (92%) vs. males (80%) (p=0.051).
Conclusions: More than one third of patients with knee OA reported improved or stable physical and mental health after completing PT for their condition. The degree of benefit did not relate to radiographic severity. While OA is diagnosed and characterized by radiographic measurements, there are variables beyond the radiographic imaging that impact patient outcomes.
