Objectives: Osteoarthritis is the most common joint disease of adults worldwide. Despite total knee arthroplasty (TKA) demonstrating high levels of success, 20% of patients report dissatisfaction with their result.
VOXX Wellness Stasis Socks are embedded with a proprietary pattern of neuro-receptor activation points that have been proven to activate a precise neuro-response, according to the pattern theory of haptic perception, which stimulates improvements in pain and function.
The use of this technology in TKA patients may prove beneficial as an adjunct to recovery as many patients suffer from deficits to their proprioceptive system caused by ligamentous damage and alterations to mechanoreceptors during the procedure.
We hypothesized that VOXX Wellness Stasis Socks are a safe, cost-effective and easily scalable strategy to support TKA patients through their recovery.
Design: Double-blinded, placebo-controlled randomized trial.Setting: Orthopaedic surgical practice. Hospitalized care; outpatient follow up.Participants: Patients scheduled to receive TKA were considered eligible for inclusion in the trial. 100 patients were enrolled.Interventions: Intervention group (I): VOXX Wellness Stasis socks containing receptor point-activation technology. Control group (C): VOXX Wellness Stasis socks without receptor point-activation technology. Sock use during the waking hours x 6 weeks.Main Outcome Measures: Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) questionnaire completed at baseline, 2 weeks, and 6 weeks to assess pain, stiffness and physical function.
Results: Data analysis using SPSS software. P-values, effect sizes, and confidence intervals are reported to assess clinical relevance of the finding. Physical status classifications were compared using t-test. Within-subject and between-subject differences in the mean WOMAC were analyzed by ANOVA. Effect size was analyzed using Cramer’s V. Consistent improvement in WOMAC scores for pain and stiffness at 2 weeks post op in the Intervention over the Control group. The WOMAC scores assessing physical function showed a consistent improvement at both 2 and 6 weeks post op in the Intervention group compared to Control group.
Conclusions: VOXX proved to be a low cost, safe intervention in TKA to help patients improve with regard to pain, stiffness and physical function.Author(s) Disclosures: None
Learning Objectives:
Upon completion, participants will be able to identify the impact of VOXX Wellness Sock technology in patients with knee osteoarthritis who underwent total knee arthroplasty
Upon completion, participants will be able to demonstrate an understanding of the use of the WOMAC score on patient pain, stiffness, and function
Upon completion, participants will be to demonstrate an understanding of the use of non pharmaceutical adjuncts for pain management in post operative total knee arthroplasty patients
