Knee Pain Q & A

What causes knee pain?

Knee pain can occur after an injury or because of natural wear-and-tear over the years. Some of the most common reasons for knee pain include:

  • Sports injuries
  • Torn ACL or PCL ligaments or ligament laxity
  • Torn meniscus
  • Torn MCL or LCL
  • Trigger points
  • Peroneal nerve impingement
  • Osteoarthritis or bone on bone
  • Rheumatoid arthritis
  • Bursitis

Knee pain can be especially challenging because your knees must bear so much weight on a daily basis. Enduring terrible pain every time you stand or walk can make you feel frustrated and dejected. Knee pain tends to intensify over time as damage grows more serious inside your knee, so it’s important to get help as early as possible.

Do I need surgery for lasting knee pain relief?

In most cases, you can get lasting knee pain relief without needing a knee joint replacement thanks to regenerative orthopedic care at Explore Health. After knee joint replacement surgery, it can take 4-6 months, possibly up to a year, to fully recover. Knee replacement surgery often has a very painful recovery, and most patients don’t return to work for around six weeks. 

In sharp contrast, Dr. Nelson performs all regenerative orthopedic medicine treatments in the comfortable high-tech Explore Health facility in Scottsdale. You won’t spend any time in the hospital, and there’s generally little-to-no downtime after regenerative medicine treatments. 

What happens in regenerative knee pain treatments?

Dr. Nelson personalizes your knee pain treatment. Often, a combination approach is the best solution. Your treatments may include: 


In prolotherapy, Dr. Nelson injects a blend of an anesthetic, saline, dextrose. These substances stimulate your body’s natural repair processes to create new tissue and strengthen ligaments, tendons, and joint support.

Platelet-rich plasma (PRP)

Platelets are the strongest part of your blood. They trigger blood clotting and also release growth factors that encourage tissue rebuilding. With PRP treatment, Dr. Nelson centrifuges your blood to extract a platelet-rich layer. Then, he injects your PRP to bring on quick healing and pain relief in the specific part of the knee that’s damaged.

Stem cell-derived exosomes

Your stem cells emit exosomes, highly powerful cellular vesicles that can activate dormant cells to start tissue regeneration. Dr. Nelson injects exosomes in the particular part of your knee requiring regeneration and healing. 


Viscosupplementation is an injectable treatment in which Dr. Nelson uses hyaluronic acid to coat the areas where you’ve lost knee cartilage and thus lubrication. This gel-like substance helps to restore normal knee function and provide a cushion to absorb the shock on the knee to reduce pain and restore function. For osteoarthritis, viscosupplementation combined with other regenerative medicine treatments is the best way to beat pain and enjoy normal knee function without surgery.

Following these regenerative medicine treatments, many elective knee replacement candidates have canceled their surgery. Find out how these regenerative orthopedic treatments can help you beat knee pain by calling Explore Health or booking the online scheduler now.
