About this trial

To demonstrate the potential benefits and risk of active sub-threshold stimulation in the treatment of chronic knee pain as compared to subjects that did not have active stimulation. Improvement will be assessed in relation to the clinical outcome measures of pain, with primary endpoint; Pain relief rate as measured by the number of subjects with greater or equal to a 50% decrease in pain on the visual analog scale, comparing baseline to the 1-month follow-up.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Wireless neuromodulation

    Device

    A needle and catheter are carefully inserted near the enervated nerve. The stimulator is then placed through the catheter close to the nerve. The proximal end of the stimulator is then sutured underneath the skin to prevent migration.

Treatment groups

100 Participants
are divided into 2 treatment groups
Group A: InterventionalExperimental treatment 1 intervention
Group B: PlaceboPlacebo comparator 1 intervention

Trial outcomes

Primary outcomes

1

Responder rate

A. Percentage of patients with at least 50% improvement in the knee pain identified at baseline compared to 3 months post full implant of the StimQ PNS System pain identified at baseline compared to 6 months post full implant of the Freedom PNS system with the VAS

Time frame
1 month

Secondary outcomes

1

Mankoski pain scale

The Mankoski Pain Scale is a numerical scale from 0 to 10, with 0 representing no pain and 10 representing the worst pain imaginable. As pain is a subjective experience and individuals may interpret the severity of their pain differently, the MPS includes descriptions of each level of pain intensity to standardize the pain interpretation across subjects enrolled in this study.

Time frame
1 month
2

Koos Jr

The KOOS assesses patient knee pain, function in daily living, function in sport and recreation, and knee related quality of life. Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms. The KOOS is a patient reported joint-specific score, useful for assessing changes in knee pathology over time, with or without treatment

Time frame
1 month
3

Global Perceived Effect scales (GPES)

Patient satisfaction with the implant will be measured by assessing global perceived effects (GPES) on a 7-point scale (1 = worst and 7 = best) Scale from 1 (no change) to 7 (a great deal better) describing improvement with therapy

Time frame
1 month
4

McGill Short Form (SF-MPQ-2)

The SF-MPQ-2 is a patient self-reported depression and pain quality questionnaire consisting of 22 questions, with all questions scored on a scale of 0 to 10. Answers on a scale of 0 (none) to 10 (worst possible)

Time frame
1 month
