Effect of Distal Needling on Knee Pain Using Acupuncture Techniques

The main novel features of this study:

• First aim to assess the effect of distal needling on knee pain
• Second aim to directly compare two acupuncture techniques, placebo, needling at "wrong" places and "correct" needling for knee pain

Advantages of the study compared to published data:

• Distal needling - enables assessment of range of motion (ROM) and pain level during needling.
• Both acupuncture systems rely on minimal questioning, which simplifies the patient-practitioner interactions.
• Exploratory studies in the clinic of DP show that it is possible to distinguish between "correct" and "incorrect" needling, at least in the short term. Long term effects have not been assessed yet.

Inclusion criteria

• Adult patients (> 18 years old), suffering chronic stable pain score >40 mm on 100 mm VAS of the knee due to patellar tendonitis.

• Adult patients (> 18 years old), two weeks after ACL reconstruction surgery (with or without meniscal involvement), with pain score >40 mm on 100 mm VAS of the knee (all patients at this stage have significant ROM limitation).
