Are patients with knee osteoarthritis aware that platelet-rich plasma is a treatment option?

Osteoarthritis (OA) is a prevalent joint disease, particularly affecting the knees. This condition is often managed through various treatments, including intra-articular injections such as corticosteroids (CS), hyaluronic acid (HA), and platelet-rich plasma (PRP). PRP has shown promising outcomes in recent studies although it does lack strong endorsement in some clinical guidelines due to inconsistent results and lack of standardized results. This study was conducted to assess patient awareness and the frequency of PRP offered for the treatment of knee OA, compared to CS and HA. In a cross-sectional study, 46 knee OA patients were surveyed regarding their knowledge and experiences of CS, HA, and PRP injections. The questionnaires were administered between September 2022 and February 2023. Additionally, the study evaluated the severity of patients knee OA, using the Western Ontario and McMaster Universities Arthritis Index, and gathered demographic information from the participants. CS injections were offered to 93.5%, and 100% of participants had previously heard of this type of injection. HA injections were offered to 37%, and 65.9% of participants had heard of them. PRP was offered to 2%, and 6.5% had ever heard of it. This study underscores the limited awareness and utilization of PRP among knee OA patients. Patients and physicians need to be more informed of all of the treatment options available for knee OA, especially orthobiologics such as PRP. Future research in larger, diverse populations is needed.

Case Report: Virtual Reality Neurofeedback Therapy as a Novel Modality for Sustained Analgesia in Centralized Pain Syndromes.

Neurofeedback (NFB) Therapy is a form of biofeedback, using the electroencephalogram (EEG) that has been in use since the 1970s, serving as a non-pharmacological intervention for epilepsy and psychiatric conditions such as anxiety, depression, insomnia, PTSD, post-concussive syndrome, and now, centralized pain. Chronic pain can increase neuronal activity and eventually causes poor modulation of pain messages. With the emergence of Virtual Reality (VR) in acute pain management, and the contraindications of opioids in chronic pain, applying novel biotechnologies seems like the next frontier in multimodal pain management. In this study, the VR and NFB technologies were fused together (VR-NFB) and used as a novel treatment modality for a 55-year-old woman who suffered from chronic pain secondary to spondylolisthesis with cervical, thoracic, and lumbar disc herniations after a motor vehicle accident with comorbid depression, anxiety, sleep deprivation, and difficulty with activities of daily living, and inability to participate in physical therapy. Our case reports on the sustained analgesia achieved for 1 year after a trial of VR-NFB, and the usefulness of neuromodulation in centralized pain syndromes.
