Implantation of Gold Beads to Relieve Discomfort From Knee Osteoarthritis

Not Applicable
Completed
Conditions
Osteoarthritis, Knee
Registration Number
NCT00487370
Lead Sponsor
Research Unit Of General Practice, Copenhagen
Brief Summary

The purpose of this study is to determine whether implanting gold beads extraarticularly in five acupuncture-points around a knee improves pain, stiffness and function in patients with knee osteoarthritis.

Detailed Description

Osteoarthritis (OA) is one of the most common diagnoses made in general practice and among the most common causes of disability in older people. Acupuncture is a well-founded supplement or alternative to pharmacological and surgical treatment methods. The improvement is, however, often brief, so to preserve the initial effect the acupuncture has to be repeated at regular intervals.

In veterinarian medicine implantation of gold-beads in acupuncture-points around a joint has been used mostly in dogs for at least 30 years in the treatment of OA. The effect measured on eating pattern, physical activity and signs of pain last for several years. It may be hypothesized that implanting gold in acupuncture points acts as a continuous acupuncture stimulation.

The purpose of this one year randomised, controlled trial of middle-aged and elderly patients is to examine the effect of implanting gold beads extraarticularly in five acupuncture-points around a knee with OA.

Primary Outcome Measures
NameTimeMethod
Pain from the knee osteoarthritis is evaluated by the patient with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).0, 1, 3, 6, 9, and 12 months
Stiffness is evaluated with the WOMAC questionnaire.0, 1, 3, 6, 9, and 12 months
Function is evaluated with the WOMAC questionnaire.0, 1, 3, 6, 9, and 12 months
The same orthopaedic surgeon assesses the patients knee score using the Knee Society Clinical Rating System.0, 6, and 12 months
The same orthopaedic surgeon assesses the patients function score using the Knee Society Clinical Rating System.0, 6, and 12 months
Secondary Outcome Measures
NameTimeMethod
The time from implantation until the effect possibly sets in.The entire study period
The effect of the initial screening by conventional acupuncture - in relation to the five primary outcome measures.2 months before randomisation
Side-effects and discomfort from the implantation, primarily whether the implanted gold beads will migrate during the study period.The entire study period
