Pilot Exploration of Platelet Characterization of Platelet Rich Plasma Created by Two Different Systems

The investigators would like to study the differences in the quality of Platelet Rich Plasma (PRP) between two different machines in those with knee osteoarthritis. Knee osteoarthritis means your cartilage has been worn down, and it affects your knee joint. Both machines, the APEX Biologix XCELL PRP System and the Emcyte PurePRP Supraphysiologic Concentrating System, are FDA approved, commercially available, and makes PRP. The investigators will check if the platelets in the PRP have different amounts or work differently. The investigators will also assess participants symptoms after the injection and compare the two different preparation systems.

Allogeneic vs Autologous PRP for Diabetic Wounds in Renal Dysfunction: a Randomized Controlled Trial

Diabetic wounds are difficult to heal. Autologous platelets in diabetic patients with renal insufficiency have poor function. Allogeneic platelet plasma has a promising application prospect. Comparing the efficacy and safety differences between allogeneic platelet plasma and autologous platelet plasma is of significant importance and value for the clinical application.

Efficacy and Safety of Pulsed Radiofrequency Combined With Platelet Rich Plasma to Treat Idiopathic Glossopharyngeal Neuralgia (GPN)

To investigate the efficacy and safety of the application of PRF combined PRP to the for the treatment of GPN.

Microfracture With Platelet Rich Plasma Gel Injection for Osteochondral Lesion of the Talus

The goal of this clinical trial is to learn if combined local injection of platelet rich plasma (PRP) gel adds clinical efficacy to isolated arthroscopic microfracture in treatment of osteochondral lesion of the talus (OLT). The interface integration of the injured area will also be assessed via radiographic follow-up. The main questions it aims to answer are: * Does arthroscopic microfracture combined with PRP gel injection improve ankle function of participants based on American Orthopedic Foot and Ankle Society (AOFAS) Score? * Does arthroscopic microfracture combined with PRP gel injection improve interface integration of the injured cartilage on magnetic resonance imaging (MRI)? Researchers will compare arthroscopic microfracture with concomitant local injection of PRP gel to isolated microfracture to see if intraoperative PRP gel injection adds clinical efficacy to isolated arthroscopic microfracture in treatment of OLT. Participants will: * Undergo either isolated arthroscopic microfracture or microfracture with intraoperative injection of PRP gel * Receive clinical follow-up 3, 6, 12, and 24 months after surgery and answer scales of ankle function assessment * Take MRI preoperatively and 6, 12 and 24 months after surgery
