Given that the knee joint is the largest in the body, knee injuries can occur unexpectedly. These injuries are not exclusive to athletes, as they become more common with age. Nevertheless, many knee pains, injuries, and conditions can find relief through Regenerative Medicine or Platelet-Rich Plasma Injection Therapy.

Knee pain can arise from various conditions, although not all can be effectively treated with PRP therapy. In such cases, considering Regenerative Medicine Therapy as an alternative to knee surgery becomes a viable option. What’s remarkable about Regenerative Medicine Therapy is its capacity not only to address knee injuries but also to facilitate the healing of damaged tissues. Additionally, it can aid in the improvement of issues like ACL and MCL tears, muscle and ligament injuries, bone fractures, bone degeneration, and even arthritis. At Opdahl Regenerative Medicine, we’ve witnessed numerous patients achieve remarkable results after completing their therapy. Although there may be some activity restrictions post-therapy, Regenerative Medicine Therapy typically involves minimal to no downtime following the procedure.

Regenerative Medicine for Knee Pain

Platelet-Rich Plasma (PRP) injections, as an autologous therapy sourced from the patient’s own body, represent an advanced form of specific blood cells that accelerate the healing process in injured areas. Research into PRP has shown significant success in numerous patients with prevalent knee conditions. A multitude of studies conducted since 2010 have consistently demonstrated substantial improvements in patients’ knee conditions following the application of this regenerative technique. These improvements were observed and documented at three months, six months, and one year post-treatment.

Knee pain can arise from various causes and is a widespread issue for many individuals. Ensuring that the right treatment aligns with an accurate diagnosis is crucial for effectively addressing these injuries. Regenerative Medicine and Platelet-Rich Plasma Injection Therapy offer potential solutions for many knee conditions, including osteoarthritis, tendonitis, and knee degeneration.

If you have knee pain, some common causes include:

Knee Pain

Knee pain can be caused by a variety of reasons and is very common in many people. Making sure the correct treatment is accompanied by an accurate diagnosis is essential to repairing the injuries. If you have knee pain, some common causes include:


Arthritis is among the most common causes of knee pain, and there are many treatments available.

Baker’s Cyst

A Baker’s cyst is swelling in the back of the joint, and is usually a sign of another underlying problem such as a meniscus tear.


This is most common in people who kneel for work, such as gardeners or carpet layers. The most common bursa affected around the joint is just above the kneecap.

Cartilage Injuries | Meniscal Tear

Cartilage tears are seen in young and old patients alike, and are also an extremely common cause of knee pain.

Chondromalacia Patella

Chondromalacia causes knee pain under the kneecap and is due to softening of the cartilage. It is most common in younger patients (15-35 years old).

Dislocating Kneecap

A dislocating kneecap causes acute symptoms during the dislocation, but can also lead to chronic knee pain.

Knee Effusion/Swelling

A knee effusion refers to an accumulation of fluid within the knee joint capsule (swelling of the knee).

Ligament Injuries

Ligament injuries commonly occur during athletic activities and can cause discomfort and instability.

Medial Collateral Ligament (MCL) Injury

An MCL injury is a sprain or tear to the medial collateral ligament. The MCL is a band of tissue on the inside of your knee.

Posterior Cruciate Ligament (PCL) Injury

A PCL injury is a sprain or tear to the posterior cruciate ligament. The PCL is a band of tissue on the outside of your knee.

Osgood-Schlatter Disease

Osgood-Schlatter disease is a condition seen in adolescents and is due to irritation of the growth plate just at the front of the joint.

Osteochondritis Dissecans

Osteochondritis dissecans (OCD) is another condition seen in adolescents due to the growth of the bone around the joint.

Patellar Tendonitis

Tendonitis around the joint is most commonly of the patellar tendon, the large tendon over the front of the knee.
