Trial Title: Hyaluronic Acid vs Platelet Rich Plasma: Effects on Clinical Outcomes and Intra-articular Biology for the Treatment of Knee Osteoarthritis

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: TRIPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* 18-80 years old~* Mild to moderate unilateral, symptomatic osteoarthritis of the knee~* No recent (within 3 months) intra-articular intervention to the affected knee~Exclusion Criteria:~* Knee instability~* Varus/Valgus alignment \>5 degrees~* Bilateral knee osteoarthritis~* Systemic inflammatory arthropathy~* Known history of anemia, coagulopathy, or present use of blood thinners

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 80 Years
- Healthy Volunteers: t

Study Arms:
- Hyaluronic Acid (HA) (Type: ACTIVE_COMPARATOR): Hyaluronic acid administered as an intra-articular injection under ultrasound guidance as a series of three weekly injections to the affected knee. 3 weekly injections are of ultra high molecular weight hyaluronan (16mg) in a 2mL injection.
- Platelet-rich Plasma (PRP) (Type: EXPERIMENTAL): Platelet-rich plasma administered as an intra-articular injection under ultrasound guidance as a series of three weekly injections to the affected knee. 3 weekly injections are of leukocyte poor, buffer/additive free, singe spin, platelet-rich plasma averaging 4mL in volume.

Based on this trial design, predict the completion outcome and termination type (if applicable).
