Clinical Trial Summary

Common medical therapies for knee osteoarthritis are patient education, drug and physical therapy, exercise and surgery. These modalities may offer improvement but drugs and surgery carry significant risk. Manipulative therapy for KOA gives pain relief and increased function. However, research suggests addition of manipulative and soft tissue therapy (to the entire kinetic chain: lumbosacral, sacroiliac, hip, knee, ankle and foot joints), may give a better outcome. Exercise therapy is considered an effective and standard care for KOA.

Description:

Patients seek treatment from chiropractors for osteoarthritis (OA) and Knee OA (KOA). Significant KOA impacts 10 % of individuals aged ≥63 particularly with radiographic changes; and by age 65, 80% have these x-ray changes. KOA may be the largest cause of decreased mobility, function, disability and pain in people aged ≥ 50 in the US. KOA causes 30% > age 60 to experience decreased social activities of daily living, increased cardiovascular risk, increased fall risk and secondary depression. Overall KOA prevalence is 4% in young adults, 85% in those > 75. Beyond great personal suffering - in the US, annual financial costs associated with OA were $60 billion per year in 2000 and, for all OA and rheumatic disease $128 billion in 2003. Estimates in 2005 were 27 million people suffer significantly due to OA and by 2020 in the US and other developed nations > 12 million will suffer serious, and 19 million minor to moderate work or activity related disability from OA and KOA, with the highest prevalence expected in women.

Medical care commonly prescribed for KOA is lifestyle accommodation (decreased activity, a cane, high chairs and toilet seats, etc), non-steroidal anti-inflammatory drugs (NSAIDS), anti-arthritics, steroids, various and sundry prescription and non-prescription oral and topical medications and exercise. Randomized controlled trials (RCTS) support exercise for KOA treatment, proven superior to placebo. At least 50% (and periodically up to 90 percent) of KOA patients regularly use NSAIDs. Frequent minor but intermittently serious gastrointestinal and cardiovascular adverse reactions to chronic use of NSAIDS occur, and there is evidence that using exercise/rehabilitation with or without manipulative (MAN) therapy may give safer, similar or equivalent relief. Supported by earlier RCTs, MAN therapy with and without soft tissue and exercise therapy for KOA appears superior to placebo and equal or superior to exercise. Although Chiropractic has conducted and published two RCTs of manipulative therapy for KOA, the profession has not yet conducted an RCT with combined full kinetic chain MAN therapy, soft tissue and rehabilitation versus standard care (rehabilitation or exercise therapy) nor studied optimum dose for various patients. 1). in effect only 1 study of such combined care (MAN therapy, soft tissue and rehabilitation or exercise therapy) exists; 2) more studies of MAN therapy combined with rehabilitation are needed to establish: a). equivalent or b). superior treatment efficacy with full kinetic chain therapy and to c). use 'dose time to response' techniques to study the optimum number of treatments for various patients and (to help determine who will respond and will not respond and why) and d)collect data to develop future cost effective research.

Significant morbidity and occasional mortality from NSAID and drug-related complications and surgery; difficulty in obtaining compliance with prolonged exercise protocols; apparent similar, equivalent or superior outcomes (manipulative therapy with and without, but possibly superior with, combined rehabilitation) in pain relief, mobility and function; the possibility of decreasing falls with their appalling sequela in morbidity, mortality and expense; justifies further research into multimodal manipulative therapy for treatment of KOA. Data suggests such full kinetic chain MAN therapy with rehabilitation may give earlier, effective, less costly outcomes and reflects a common clinical chiropractic approach to KOA. In addition to the knee joint, KOA disability has been demonstrated to be significantly worsened by hip joint dysfunction, for example restricted hip flexion increases KOA pain and dysfunction; and there are similar associations throughout the full kinetic chain for example lumbosacral spine joint dysfunction may increase knee pain and dysfunction. Manipulative therapy applied appropriately to the full, kinetic chain (to the full axial and appendicular skeleton -the spine and extremities) combined with rehabilitation may be a superior treatment for knee OA.

Exclusion Criteria:

Rule out: General and internal medical disorders such as significant visual disorders, severe vestibular disorders (i.e., Meniere's), neurological (including Alzheimer's and other degenerative brain and mental disorders, disease and dysfunction) peripheral sensory disorders (severe insulin dependent diabetes), knee and hip joint replacement on side of knee that is treated (case by case otherwise), RA, instability, fracture/ and severe osteoporosis, frank avascular necrosis with or without moderate or severe deformity, lumbar herniated disc and injury, severe balance and proprioception problems (i.e., inability to stand with and/or without marked spinal, knee or hip deformity) etc. Symptoms (moderate to severe) in both knees or hips (case by case), etc. Recent history of meniscal or other knee surgery (not less than 6 months). Severe/constant self reported knee crepitus. Severe loss of knee or hip ROM and or severe deformity (in valgus, varus etc) particularly with instability. Severe depression per Beck Depression Index. Marked or severe fear of chiropractic adjustments/manipulative and or exercise procedures. Breaks for treatment longer than 3-4 weeks depending on each circumstance or merit may be construed as non-compliance and may be excluded.

Intervention

Other:
• Full Kinetic Chain Manipulative Therapy
Treatment will focus on restoring knee flexion and extension by lesser grades of mobilization and patellar mobilization along with careful high velocity low amplitude axial elongation of the knee joint. Additionally, manipulative therapy will be applied where needed to the full kinetic chain using diversified techniques, such as HVLA manipulation or mobilization. This group will receive a total of 6 treatments over a 3 week period. Outcome measures will be taken at baseline, prior to the 4th treatment and at the one week follow-up. A 3 month follow-up will be done by mail, phone or email.
• Full Kinetic Chain Rehabilitation
Rehabilitative therapy includes exercises, focused soft tissue treatment and stretch to the knee and the full kinetic chain where needed based upon functional assessment. Also included; patient advice, education and home exercise recommendations for managing their KOA. This group will receive a total of 6 treatments over a 3 week period. Outcome measures will be taken at baseline, prior to the 4th treatment and at the one week follow-up. A 3 month follow-up will be done by mail, phone or email. The rehabilitative therapy group will be required to attend the initial treatment/training, the 4th visit and 1 week follow-up. Treatments 2, 3, 5 and 6 are considered optional; they may be done at home
• Full Kinetic Chain Manipulative Therapy with Rehabilitation
This arm is a combination of the manipulative therapy arm and the rehabilitative therapy arm. This group receives 6 treatments over a 3 week period with a one week follow-up on site and a 3 month follow-up by mail, phone or email.
