Effects of Reparel™ Knee Sleeve on Knee Osteoarthritis

The goals of treating knee osteoarthritis (OA) is to improve or maintain quality of life, mobility and function, pain relief, and improve inflammation. The different treatment options for knee OA have been extensively studied and implemented, but the optimum treatment is still undecided. There is a belief that anti-inflammatory sleeve technology may be beneficial in treating knee OA. The purpose of this study is to determine the clinical effects of Reparel™ knee sleeve regarding mobility, functionality, and pain outcomes in managing knee OA.

About this study

Standard knee compression sleeves have been described throughout literature to provide benefits in pain and functional outcomes through support of the ligamentous structures. Bracing is both an effective and economical treatment for osteoarthritis and serves as a crucial option in the treatment of knee OA to aid in both delaying surgery and as options for young patients, or patients that are not ideal surgical candidates. Although knee sleeves are commonly utilized treatment modalities, there is a significant paucity of literature on the effects of thermo-active braces in the treatment of knee OA. This investigation will examine this non-operative treatment modality and study it effect for the treatment of knee OA specifically by investigating the Reparel Knee Sleeve. The Reparel Knee Sleeve is a Class I Medical Device (510(k) exempt) and used in general sports medicine practice for the alleviation of knee pain. The authors expect that the Reparel thermos-active knee sleeve will have a significant effect on pain relief from knee OA.

Treatment and study plan

Reparel Knee Sleeve

Device

Patients who are recommended for non-operative management of knee osteoarthritis and have been consented in clinic to participate in the study will be given a Reparel™ knee sleeve to wear for knee osteoarthritis management. Each device will be numbered and recorded in the patient's REDCap entry for future reference if needed. Following administration of the Reparel™ knee sleeve, patients will be given instructions on how to use/wear the sleeve while performing activities of daily living or sports that had previously resulted in knee pain and also be asked to do the follows: wear the sleeve as much as they possibly can; not change their usual activities and diet during the time they are on this study; record in a diary the number of hours sleeve was worn per day; record any adverse effects or discomfort due to sleeve use; refrain from altering treatment for knee osteoarthritis.

Primary outcomes

  1. University of California, Los Angeles (UCLA) Activity Score

    Time frame: 3 months

    This is a questionnaire that measures current activity level. Patients self report their current activity level. It ranges from 1-10. A patient scoring themselves as a 1 is the lowest current activity level and represents someone who is wholly inactive. A patient scoring themselves as a 10 is the highest current activity level and represents someone able to regularly participate in impact sports.

  2. Lysholm Score

    Time frame: 3 months

    This is a questionnaire that is self-reported by the patient. It is meant to measure a patient's ability to manage activities of daily living as it relates to their knee. The score range is from 0 to 100. A score of 0 is the lowest score associated with lower ability to manage activities of daily living, and a score of 100 is the highest score associated with a higher ability to manage activities of daily living.

  3. Oxford Knee Score (OKS)

    Time frame: 3 months

    This is a questionnaire that is self-reported by the patient. It measures knee pain and function. It is scored from 0 to 48. A score of 0 represents the lowest score and is associated with higher knee pain and lower function. A score of 48 represents lower knee pain and higher function.

  4. Knee Injury and Osteoarthritis Outcome Score Pain (KOOS-P)

    Time frame: 3 months

    This is a patient questionnaire that is self-reported. It is a measure of how much pain a patient has during different activities. A score of 100 represents the lowest level of pain with different activities. A score of 0 represents the highest amount of pain with different activities.

  5. Single Assessment Numeric Evaluation (SANE)

    Time frame: 3 months

    This is a patient questionnaire that is self-reported by the patient. It represents a patient's perceived functional level of their affected joint as a percentage of normal. The score is ranged from 0% to 100%. A score of 100% is the best outcome with the patient perceiving their functional level as 100% of normal.

  6. Visual Analog Scale (VAS)

    Time frame: 3 months

    This is a patient questionnaire that is self-reported by the patient. It measures how much knee pain the patient is having. The score ranges from 0 to 10. A score of 0 represents the best outcome with the least amount of pain. A score of 10 is the worst outcome with the most amount of pain.

  7. Knee Injury and Osteoarthritis Outcome Score Symptoms (KOOS-Sy)

    Time frame: 3 months

    This is a patient questionnaire that is self-reported. It represents the amount of knee symptoms a patient has. A score of 0 represents the worst outcome with a patient reporting the most symptoms. A score of 100 represents the best outcome with patients reporting the least symptoms.

  8. Knee Injury and Osteoarthritis Outcome Score Activities of Daily Living (KOOS-ADL)

    Time frame: 3 months

    This is a patient questionnaire that is self-reported by the patient. It measures the ability of a patient to perform activities of daily living as it relates to a patient's knee. A score of 0 represents the worst outcome with patients reporting the most difficulty performing activities of daily living. A score of 100 represents the best outcome with patients reporting the least difficulty with performing activities of daily living.

  9. Knee Injury and Osteoarthritis Outcome Score Quality of Life (KOOS-QOL)

    Time frame: 3 months

    This is a patient questionnaire that is self-reported by the patient. It measures a patient's quality of life as it relates to their knee. A score of 0 represents the lowest quality of life as it relates to a patient's knee. A score of 100 represents the highest quality of life as it relates to a patient's knee.

  10. Knee Injury and Osteoarthritis Outcome Score Sports and Recreation (KOOS-Sp)

    Time frame: 3 months

    This is a patient questionnaire that is self-reported by the patient. It measures a patient's ability to perform sports and recreation as it relates to their knee. A score of 0 represents the lowest ability to perform sports and recreation as it relates to their knee. A score of 100 represents the highest ability to perform sports and recreation as it relates to their knee.
