What is Knee Pain?
The knee is one of the most common sites of pain. It is a weight-bearing joint, so in addition to all the wear-and-tear that happens from moving it every day, it also has the forces of body weight and gravity acting upon it. When structures in and around the knee—bone, cartilage, tendons, and ligaments—become damaged, the result is pain and sometimes even disability.
Knee pain has many potential sources. These can be:
- Knee osteoarthritis
- ACL injuries or injuries to other ligaments, instability
- Meniscus injuries
- Tendinitis and tendinosis
What is basic Knee Anatomy?
The knee is one of the more complicated joints. It involves three bones—the femur (thigh bone), the tibia (shin bone), and the patella (kneecap)—as well as a number of ligaments and tendons. Articular cartilage wraps the ends of the femur and tibia so they glide together smoothly, while pads of cartilage called menisci (singular meniscus) act as shock absorbers between the femur and tibia. Cartilage can also be found on the underside of the patella.
Major tendons that attach muscles in the area to bone include the patellar tendon and the quadriceps tendon. The knee also has a number of ligaments that connect the femur and tibia to each other. These include:
- Anterior cruciate ligament (ACL)
- Posterior cruciate ligament (PCL)
- Lateral collateral ligament (LCL)
- Medial collateral ligament (MCL)
Knee Pain Reviews
"Asheville Regenerative Ortho is the closest provider of Regennex treatment to my home. My company covers Regennex, and as an alternative to knee replacement (both knees) I decided to take a chance. Very happy I did. Had left knee procedure at the end of May, and that knee is almost entirely pain free now. Planning to do right knee soon. Dr Lehmann and all the staff are very professional, explained the treatment and its potential for my specific situation."- R.B. / Google / Sep 19, 2022
"I had the Regennex procedure on my left knee in May 2022. 3 months later it is nearly pain free (compared to highly painful prior). Planning to have right knee done soon. Dr. Lehman and entire staff were friendly, professional, and explained the procedure and likely outcome in detail. Very satisfied with the results so far, and hoping this delays the need for knee replacements for several years."- B.B. / Facebook / Sep 19, 2022

What are different Types of Knee Pain?
Knee osteoarthritis: Osteoarthritis, sometimes known as wear-and-tear arthritis, is the most common form of arthritis. Osteoarthritis occurs when the articular cartilage of bones in a joint breaks down, eventually leading to painful joint fluid environment. These tiny fragments of worn off cartilage cause an irritating chemical reaction in the knee fluid of the joint, which can be a large source of the pain. This explains why a joint that isn’t “bone-on-bone” can be quite painful and why a “bone-on-bone” knee can sometimes not hurt.
The knee is one of the most common sites for osteoarthritis. There is no cure for osteoarthritis, but its progression can be slowed. Traditionally, a total knee replacement was a patient’s only option for advanced knee osteoarthritis.
Meniscus tears: The menisci sit between the femur and tibia and act as a shock absorber for and secondary stabilizer of the knee. The meniscus can become torn due to age-related degeneration or trauma. Meniscus injuries are extremely common. Due to a lack of blood vessels in the area, the meniscus cannot easily heal itself. Surgery to remove these torn areas is commonly performed, but when arthritis is also present, this surgery often proves ineffective.
Ligament injuries: Four ligaments—ACL, PCL, LCL, and MCL—act as the primary stabilizers for the knee joint. ACL tears are a common source of knee pain, creating instability and preventing patients from engaging in rotational and side-to-side movement. ACL tears and other forms of ligament injuries can sometimes be treated without surgery, but full tears require a tissue graft to repair.
Tendinopathy: The quadriceps tendon, which attaches the quadriceps muscle to the kneecap, is the main tendon in the knee joint area. There is also the patellar tendon, but since it connects the kneecap to the tibia it is actually a ligament. Either or both of these tissues can become frayed and weakened through wear and tear, or torn by way of traumatic injury.
How knee pain is diagnosed?
Knee pain can stem from a variety of causes, whether it's a result of an injury, wear and tear, or natural aging. At Asheville Regenerative Orthopedics & Sports Medicine, Dr. Christie Lehman and her team use a multitude of tests and scans to pinpoint the source of your knee pain. Using physical examinations, x-rays, CT scans, blood work, and MRIs, Dr. Lehman can accurately determine what's causing your pain and prescribe a personalized treatment plan to address your knee pain.
What are Options for Treating Knee Pain?
Nearly every form of traditional knee pain treatment, be it surgical or nonsurgical, has its problems. Some, such as corticosteroid injections, can be toxic to surrounding tissue. Others, such as ACL reconstruction and total knee replacement, are complex and invasive surgeries that require a long recovery. Some medications, including opioids, only treat symptoms rather than the root cause of knee pain and can be extremely addictive.
But what if there was another option? A nonsurgical approach that is safe, effective, and easy to recover from? Enter orthobiologic treatments using a person's own growth factors and cells, commonly referred to as cellular therapy and platelet-rich plasma (PRP).
Each month, researchers produce more scientific evidence pointing to the viability of bone marrow and PRP for orthopedic pain conditions. What’s more, knee pain conditions are some of the most studied and most receptive in relation to this type of treatment.
ACL injuries: Traditionally, the only way to repair a torn ACL is through costly, invasive surgery. That may still be the most appropriate treatment option for some people, but with the advent of orthobiological treatment, there is another effective, less invasive option. Bone marrow injections have been shown in research to improve pain, function, and structural integrity in treating partial ACL tears.
Knee osteoarthritis: Knee osteoarthritis is a lifelong condition that may eventually require a total knee replacement. Conventional treatments focus on reducing pain but can carry complications. Both bone marrow and PRP have been shown in research to improve pain, function, swelling, and in some cases, increase articular cartilage thickness.
Tendinopathy: Treatment for tendinopathy is limited to pain- and inflammation-reducing medication and surgical repair. Corticosteroids, a powerful anti-inflammatory drug that can reduce pain, can actually increase the risk of a tendon rupture when used to treat tendinopathy by weakening the tissue. PRP and cells can both improve pain and quality of life without the risk of further tendon injury, according to research.
Meniscus injuries: Meniscus injuries, while common, can be difficult to treat due to a lack of blood supply. Researchers have found that PRP can increase the formation of new blood vessels in and near the meniscus, which can speed healing and reduce pain. The use of bone marrow has been shown in some studies to be effective in promoting meniscus regeneration as well.
If you are looking for an effective alternative to surgery for your painful knee condition, request an appointment with Asheville Regenerative Orthopedics. Through ultrasound-guided injections, Dr. Lehman can pinpoint the source of your knee pain and deliver safe, effective healing compounds from your own body.
Knee Pain FAQ
Is there a chance I may need surgery to relieve my knee pain?
Here at Asheville Regenerative Orthopedics and Sports Medicine, we believe that traditional options to treat knee pain, such as reconstructive surgeries and anti-inflammatory injections are significantly riskier than are usually presented. With that in mind, we will make sure to exhaust every nonsurgical, regenerative treatment option possible before we think about recommending surgery as your best option.
Why are these regenerative treatments better than surgery?
Surgeries to address knee conditions can be onerous, expensive, and are usually associated with a lengthy recovery period where you can’t be as active as you’d like. On the other hand, PRP treatment options treat your pain and inflammation with your body’s cells and require a fraction of the downtime of surgeries. Furthermore, while surgery is typically considered a long-term solution, many studies have verified the long-term benefits of regenerative knee therapies like PRP.
Can I turn to regenerative solutions after having surgeries?
Absolutely. At our Asheville, NC facility, Dr. Lehman and our skilled team often see patients who had a less-than-ideal experience with orthopedic knee surgery and want to try a more natural treatment plan.
