Managing Sharp Stabbing Pain in Knee that Comes and Goes

Last updated on November 5th, 2024 at 04:01 pm

Many people experience sharp knee pain that forces them to stop whatever they are doing. This sharp, stabbing pain in the knee that comes and goes can be caused by issues with the knee bone or the surrounding nerves. Another common cause is damage to the soft tissues around the knee joint.

Sharp, stabbing pain in the knee that comes and goes usually lasts for a short time, and occurs during specific movements. It typically goes away as soon as you stop moving. However, severe pain inside or around the knee can persist, but it often either disappears completely or fades to a mild ache.

Knee problems, like soft tissue damage or inflammation, can cause discomfort, especially if the pain is in a specific area of the knee. If the pain extends down the leg, it may indicate a nerve issue in the lower back or knee.

Causes of Sharp, Stabbing Pain in Knee That Comes and Goes

There are several causes of sharp knee pain, including:

Torn knee cartilage (the cushion in the knee joint)
Bursitis: Inflammation of the anti-friction sac
Knee arthritis: Wearing down of the knee
Loose body: A fragment of bone floating in the joint
Fracture: Broken bone
Nerve irritation

Understanding the common causes of sharp knee pain, how they manifest, and how to identify knee problems is crucial. This overview covers the causes of intense, stabbing knee pain.

1. Soft Tissue Injuries

One of the most common causes of sharp knee pain is an injury to the soft tissues in the knee. Stabbing or sharp knee pain often occurs when the knee bursa is inflamed or the knee cartilage is damaged.

2. Torn Knee Cartilage

Knee pain can happen if something gets trapped in the joint. Each knee bone has a thick layer that prevents friction between the joints and allows for pain-free movement when the knee bends. Tears in the cartilage can cause knee pain.

This can happen in two ways:

Cartilage Fragment: A small piece of cartilage might break off from the meniscus and float in the knee joint.
Bucket Handle Tear: A partial tear in the cartilage creates a loose flap still partially attached to the meniscus, known as a “bucket handle tear.” Sometimes, this flap gets caught in the joint, causing it to lock and resulting in sharp pain.

When loose cartilage gets stuck, stabbing pain and joint locking are possible. In most cases, the pain subsides after a few seconds of moving the knee, but it might take some time.

3. Knee Bursitis

Knee bursitis, which can affect any part of the knee, is another common cause of sharp knee pain. The bursae, small sacs that reduce friction between soft tissues and bones in the knee, can become inflamed, leading to intense pain.

The location of the pain can help identify bursitis. Stabbing pain might come from these areas:

Kneecap: Known as prepatellar bursitis or “housemaid’s knee.”
Back of the Knee: Possibly a Baker’s cyst.
Inner Knee: Pain in this area may indicate pes anserine bursitis.
Outer Knee: Often due to iliotibial band bursitis, common in runners.

4. Bone Problems

Several bone issues can lead to sharp knee pain. The knee contains three bones, each connecting at different joints:

Thigh Bone (Femur): Connects the hip to the knee.
Shin Bone (Tibia): Connects the knee to the ankle.
Kneecap (Patella): A small bone that sits at the front of the knee joint, moving over it as the knee bends and straightens.

5. Joint Injuries

Sharp pain may indicate a problem within the knee joint. If the cartilage wears down, either due to wear and tear or injury, it can lead to osteophytes, small bone spurs that protrude from the bone.

Without cartilage to cushion and protect these osteophytes, the bones become exposed. This often results in arthritis.

Osteophytes can cause intense irritation when the knee moves, leading to sharp, stabbing pain when bending or twisting the knee, especially during activities like sports. If you move the knee to a new position and relieve pressure from the osteophytes, the sharp pain might subside, though a dull ache could persist. People with knee pain might be able to walk normally unless they place additional pressure on the joint, like bending, twisting, running, or climbing stairs.

If sharp knee pain worsens when climbing stairs, it might indicate problems with the tibiofemoral joint. Pain that intensifies while descending stairs may point to a kneecap issue.

6. Loose Body

If something gets stuck in the knee joint, it can cause sharp pain. This can be due to a small fragment of bone or cartilage getting trapped in the joint.

A small piece of cartilage might have broken off from the meniscus. These small fragments in the joint capsule are called “loose bodies,” which can cause sharp knee pain and possibly lock the joint.

Pain typically decreases once the loose body shifts out of place, and normal knee movement returns. Loose bodies often cause intermittent pain rather than constant discomfort.

While this might not happen every time you engage in a particular activity, it could catch you off guard when you least expect it.

7. Knee Fracture

Sudden, severe, and constant knee pain following an injury could indicate a fractured bone in the knee.

A fractured bone is usually accompanied by noticeable deformity and swelling. Even slight movement of the bone can cause intense, stabbing knee pain as the broken fragments rub against each other.

It takes a lot of force to break one of the knee bones, so you’ll likely know something is wrong immediately.

8. Nerve Issues

Problems with one or more nerves running from the spine to the lower limbs can also cause pain.

Nerves in our body act like electrical lines. Several nerves in the leg originate from the lower spine and extend to various parts of the leg.

These nerves transmit signals about pressure, pain, and temperature from the muscles to the brain and spinal cord.

Pressure or irritation on the nerves can cause intense, stabbing pain. When nerves are compressed, they can cause localized pain or severe pain along the nerve’s pathway.

Activity-Caused Sharp Knee Pain

While Walking: If your knee pain worsens while walking but improves afterward, it might be arthritis. Severe pain during walking could indicate a nerve issue.
While Standing: If your pain increases when standing but gets better when you move, it might be arthritis.
While Bending: Sharp pain when bending your knee could be due to cartilage damage or a ligament injury.
While Climbing Stairs: If you experience sharp pain while climbing stairs, it could be a problem with the joint between your thigh and shin bones. Pain that worsens when descending stairs might be related to issues with the kneecap.

How to Manage Sharp, Stabbing Knee Pain That Comes and Goes

If you experience sharp, stabbing knee pain that comes and goes, here’s what you can do:

Try Physical Therapy:

Physical therapy can be helpful for this type of pain in different ways. A therapist will work with you to improve your movement without causing more pain. They’ll help strengthen your muscles to protect weak ligaments, joints, and tendons. They’ll also work on increasing your range of motion so you can move with more confidence and less pain.

Take Anti-Inflammatory Medications:

Anti-inflammatory medications can reduce swelling caused by your injury or condition and temporarily ease the pain.

Knee Pain Injections

Knee pain is often treated with injections given directly into the affected joints. These injections can help with conditions like osteoarthritis, tendonitis, degenerative arthritis, and other joint problems. However, if the condition worsens, you might need orthopedic surgery in Dallas. There are two main types of injections:

Corticosteroids: These are used to reduce sudden arthritis pain for a few months.
Hyaluronic Acid: This thick fluid mimics the body’s natural fluid and is injected into the affected knee(s) to lubricate it. Hyaluronic acid injections can reduce pain for up to six months, allowing you to return to your favorite activities.

Research shows that PRP (Platelet-Rich Plasma) injections may help patients with osteoarthritis. Other issues like IT band syndrome, pre-patellar bursitis, and infrapatellar bursitis can also cause sharp knee pain. If you are experiencing such pain, you should see a knee specialist in Dallas for diagnosis and treatment planning.

Rest:

Depending on your injury or condition, resting might help. In some cases, rest can reduce swelling and inflammation. However, if you have a bone fracture, it’s best to consult your doctor to determine the best approach.

Use Ice and Heat Therapy:

Ice can help reduce swelling and pain, while heat can provide comfort and relieve pain.
