CMC-1 joint, thumb basal joint, PRP, Platelet-rich plasma
Brief summary
This is a randomized double-blinded randomized comparison between injection of platelet rich plasma (PRP) and placebo for thumb basale osteoarthritis.
Detailed description
The aim of this study is to evaluate if high-concentration PRP injection decreases pain and disability in patients with thumb base osteoarthritis in the short-term and compare the effect to placebo.90 patients will be inlcuded (45+45). The primary outcome is pain on load (numerical rating scale) after 6 months. Patient-rated outcome measures, pinch grip and key pinch, range of motion of the CMC.1 joint will be assessed before treatment and at 3, 6 and months after the injection. Participants and assessors will be blinded.
Interventions
Intra-articular injection of platelet rich plasma (PRP)
Intra-articular Saline injection (0,6-1ml)

Eligibility
Inclusion criteria
* Osteoarthritis in the thumb base * Radiological Eaton Littler class 1-3. * Clinical signs of thumb base osteoarthritis )pain at palpation of the CMC-1 joint and pain during provocation/grinding test).
Exclusion criteria
* Rheumatoid arthritis * Ongoing infection in the hand or wrist * History of gout or pseudogout in the hand * Inability to co-operate with the follow-up protocol (language difficulties, severe psychiatric disorder, cognitive impairment, drug addiction). * Chronic pain syndrome / centralized pain. * Intra-articular injection in the affected joint within 6 months. * Eaton Littler class 4 (symptomatic STT joint osteoarthritis).
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain on load in thumb | 6 months after the first injection. | Pain on load (numerical rating scale (NRS) 0-100, higher score represents more pain) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient-rated Wrist and Hand (PRWHE) score | 3 months | 0-100, higher score represents more disability |
| Nelson thumb score | 3 months | 0-100, lower score represents more symptoms |
| HAKIR symptom score (HQ-8) | 3 months | 0-100, lower score represents more symptoms |
| key pinch and pinch strength | 3 months | key pinch and pinch strength (kg) |
| Radial and palmar abduction | 3 months | Radial and palmar abduction of the first metacarpal (degrees) |
