Top 7 Pain in the Inside of the Knee Causes

  1. 1.Patellofemoral Pain Syndrome

    The kneecap (patella) is located directly in front of the thigh bone (femur), and should normally glide freely up and down. In this condition, called patellofemoral pain syndrome, the kneecap may rub against the thigh bone instead of gliding smoothly, causing damage and pain.

    You should visit your primary care physician. While you can safely take steps to treat this condition at home (avoiding strenuous use of the knee and taking over-the-counter pain medication), your doctor may coordinate care with a physical therapist to help manage your pain and function of the knee.

    Rarity:
    Common
    Top Symptoms:
    knee pain, pain in one knee, knee pain that gets worse when going up stairs, dull, achy knee pain, knee pain that gets worse when squatting
    Symptoms that always occur with patellofemoral pain syndrome:
    knee pain
    Urgency:
    Primary care doctor
  2. 2.Meniscal Injury

    A torn meniscus is one of the most common knee injuries. Any activity that causes forceful twisting of the knee, especially when putting the pressure of one's full weight on it, can lead to a torn meniscus.

    Conservative treatment such as rest, ice and medication is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgical repair, which can be best determined by your doctor or physiotherapist.

    Rarity:
    Common
    Top Symptoms:
    pain in one knee, knee stiffness, pain in the inside of the knee, knee instability, knee pain from an injury
    Urgency:
    Primary care doctor
  3. 3.Dislocated Kneecap

    The kneecap connects the muscles in the front of the thigh to the shinbone (tibia). When the kneecap slips out of the groove, problems and pain often result.

    You should visit your primary care physician within the next 24 hours. The first step is to return the kneecap to its proper place, a process called reduction.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in one knee, knee injury, knee pain from an injury, swollen knee, pain in the inside of the knee
    Symptoms that always occur with dislocated kneecap:
    kneecap sliding out to the side, knee pain from an injury
    Urgency:
    In-person visit

  4. 4.Knee (Mcl) Sprain

    The medical collateral ligament (MCL) links the thigh bone and the shin bone on the inner side of the knee joint. An MCL sprain is any damage done to this ligament (usually through twisting/force during sports).

    Depending on the severity of your knee pain, you should go see your doctor at your earliest convenience or go to an urgent care clinic if needed. Your doctor may prescribe you pain medication, and will ask you to refrain from physical activity and possibly partake in rehabilitation/ physical therapy.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in one knee, knee injury, knee pain from an injury, pain in the inside of the knee, sports injury
    Symptoms that always occur with knee (mcl) sprain:
    pain in one knee, knee pain from an injury
    Symptoms that never occur with knee (mcl) sprain:
    mild knee pain
    Urgency:
    Primary care doctor
  5. 5.Repeated Kneecap Dislocation (Patellar Subluxation)

    Recurrent patellar subluxation is the continued instability of the kneecap, which causes anterior knee pain and usually occurs laterally. It occurs unpredictably with varying durations.

    Your doctor will be able to make a diagnosis regarding the severity of your recurrent patellar subluxation using X-ray and/or MRI. Basic rehabilitation is the preferred conservative treatment, but in certain cases surgery may be necessary to stabilize the recurring dislocations.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in one knee, dull, achy knee pain, pain in the front of the knee, pain in the inside of the knee, swollen knee
    Symptoms that always occur with repeated kneecap dislocation (patellar subluxation):
    kneecap dislocation
    Urgency:
    Primary care doctor
  6. 6.Severe Kneecap Dislocation

    The kneecap connects the muscles in the front of the thigh to the shinbone (tibia). When the kneecap slips out of the groove, problems and pain often result.

    You should seek immediate medical care at an urgent care clinic or ER, because this is a concerning type of knee dislocation that cannot be easily pushed back in place (reduced). A consult from an orthopedic surgeon may be needed to evaluate possible damage.

    Rarity:
    Rare
    Top Symptoms:
    constant knee pain, pain in one knee, knee injury, knee pain from an injury, swollen knee
    Symptoms that always occur with severe kneecap dislocation:
    knee pain from an injury, kneecap dislocation, constant knee pain
    Urgency:
    Hospital emergency room
  7. 7.Pigmented Villonodular Synovitis

    The synovium is a thin layer of tissue that surrounds joints, providing a small amount of fluid to lubricate the joint and aid in movement. In pigmented villonodular synovitis (PVNS), the synovium thickens and overgrows. This mass typically only affects one joint, is not cancerous, and does not spread to other parts of the body.

    You should visit your primary care physician who will likely coordinate care with a muscle and bone specialist (orthopedic surgeon). The treatment for PVNS is surgery and radiation therapy.

    Rarity:
    Rare
    Top Symptoms:
    pain in one knee, spontaneous knee pain, swollen knee, joint pain, pain in the inside of the knee
    Symptoms that never occur with pigmented villonodular synovitis:
    knee instability
    Urgency:
    Primary care doctor
