Chronic Knee Pain: Causes and Treatment Options

In the US, chronic knee pain is a common condition, with people suffering from it due to numerous causes and reasons. Severe pain and inflammation during this condition make it difficult for patients to function and walk normally. People also find difficulty in performing everyday tasks. Because the knee joint has a complex structure, many factors implicate chronic knee pain. Usually, people experience knee pain and inflammation because their knee stops functioning properly. The problems arise due to medical conditions and trauma. This article includes some common causes and treatment plans for knee pain. Read this article and seek knee pain relief.

Chronic Knee Pain

Causes of Knee Pain

Temporary knee pain and chronic knee pain are two different conditions with different causes. People develop temporary knee pain due to accidents or injury. Once you recover from the injury, temporary knee pain will go away. But, chronic knee pain requires proper treatment, which will depend on the cause. Therefore, it is essential to learn about the cause of the pain. A pain management doctor diagnoses the affected knee and identifies the actual cause of the pain. Here are some causes of chronic knee pain:

  • Bursitis is inflammation of the knee due to overly used muscles. You may also develop this condition after an injury.
  • Tendinitis affects the front part of your knee. The pain grows worse when you climb up the stairs or walk up an inclined plane.
  • Osteoarthritis is a condition that occurs due to deterioration and degeneration of the joints, which causes inflammation.
  • You develop gout arthritis because of uric acid buildup.
  • Knee cap dislocation is another common cause of chronic knee pain.
  • Chondromalacia patella indicates that you have damaged cartilage under the kneecap.
  • Baker’s cyst also causes severe pain. This is a condition in which synovial fluid builds up behind the knee.
  • Meniscus tear is a rupture in knee cartilage.

Here are some factors that may increase the severity of pain:

  • Sprains and strains
  • Infection
  • Overuse
  • Bad posture
  • Improper muscle stretching
  • Injury affecting knee structure.

Treatment for Knee Pain

As we discussed above, you may develop chronic knee pain due to numerous reasons. Treating the cause of the pain eventually reduces the chronic pain. Here are a few effective treatment plans for chronic knee pain:


When you visit a pain management doctor, they will prescribe pain-relieving medications. For instance, if you develop knee pain because of gout or rheumatoid arthritis, complete recovery is possible with prescribed medication.


Most doctors recommend physical therapy to strengthen the muscles. When the muscles around the knee are strong, they keep your knee joint stable. Furthermore, a pain management doctor may also suggest strengthening exercises to alleviate the pain. Participating in sports and other activities may also shift pressure away from your knee.


If medication and therapy don’t work, your doctor may inject medication directly into the knee joint. Here are some examples of substances that a pain management doctor may inject:

  1. Corticosteroids

Corticosteroid injections reduce the symptoms of arthritis flare-ups. These injections are meant to offer instant relief from pain.

  1. Hyaluronic Acid

Hydraulic acid works as a lubricant and eases pain, and improves mobility. Hyaluronic acid is a thick fluid and lubricates joints. Sometimes, a single dose is enough to provide relief, but it’s common for patients to require more doses. Consequently, the treatment process can last up to six months.

  1. Platelet-Rich Plasma (PRP)

PRP includes various factors or components that promote healing and reduce inflammation. According to various studies, PRP is helpful for osteoarthritis patients.

When it comes to surgery, you shouldn’t make an uninformed decision. Consult with a professional pain management doctor such as Dr. Matthew Grimm in New York City. He can help you choose the best treatment methods with a high success rate. Here are a few surgical reconstruction procedures to reduce chronic knee pain:

  1. Arthroscopic Surgery

In this surgical method, doctors use a fiber-optic camera to evaluate the internal condition of the damaged joint. The doctor makes few incisions around the knee to insert the tool. Arthroscopy removes loose bodies from the joint. Furthermore, it helps with ligament reconstruction and damaged cartilage.

  1. Partial Knee Replacement Surgery

As the name suggests, partial knee replacement surgery involves removing the damaged part of the knee. After removing the portion of your knee, the surgeon will place insert a plastic or metal part to improve mobility.

  1. Total Knee Replacement

In this process, the doctor removes damaged cartilage and bone from your kneecap, shinbone, and thighbone and places an artificial joint instead. The material of artificial joints may vary from polymers, high-grade plastics to metal alloys.

Do You Have Knee Pain? Structure of Knee & Types of Conditions:

Knee pain is quite common, and it can affect you at any age. It may be due to an injury, such as torn cartilage or a ruptured ligament. Many medical conditions like infections, gout, and arthritis can be the reason for knee pain. Symptoms of knee pain may include stiffness, swelling, and pain.

Knee Pain: Types of Conditions

The function that knee joint performs is bending, strengthening, and bearing the weight of the body. The knee is not only a simple joint that hinges but also twists and rotates, which increases the functions that knee performs. The knee relies on several structures to perform all the actions and to support the entire body. These structures include tendons, cartilage, ligaments, and bones.

Structure of Knee

1.     Tendons:

Tendons are the bands that connect muscles to bones. These are fibrous bands. The quadriceps and patellar tendons are important tendons in the knee.

2.     Cartilage:

These cartilaginous structures are also called menisci. Cushioning knee joint is the primary job of menisci.

3.     Ligaments:

These are also the fibrous bands just like tendons and connect femur with the tibia. There are four important ligaments. Ligaments that provide rotational stability to the knee from front and back are the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). Those ligaments that provide medial and lateral stability to the knee are called medial collateral ligament (MCL) and lateral collateral ligament (LCL).  MCL provides constancy from inside and LCL from the outside.

4.     Bones:

There are four bones in the knee joint. The thighbone is in the top portion. The thighbone is also called the femur. The patella is present along the front femur. It is the kneecap. Tibia helps in the bottom weight of the joint and is in the lower leg. The remaining bone is the fibula, and it is present in the calf. It provides ligament attachments to create stability.

Conditions for Knee Pain

There are many reasons for knee pain. There is a list of few problems below:

1.     Dislocated Kneecap:

Doctors call it “patellar dislocation.” It occurs when your kneecap slides from its location, causing pain and swelling. Sometimes the knee bends, causing severe pain. This condition takes place when your knee is straight, and the lower leg is bent outwards when twisting. It also happens when the knee bends, and the kneecap is hit. For reduction, doctors push the patella towards the midline while straightening the knee.

2.     Bursitis:

A sac that holds fluid that’s under the skin above your joint is the bursa. The function of the bursa is to prevent friction when joints move. When you overuse, fall, or bend your knee a lot, it can irritate the bursa, leads to swelling and pain. Your doctor might call this condition prepatellar bursitis.

3.     Meniscal tear: 

Sometimes injury on your knee can cause the cartilage to rip. Cartilage has a rough edge, and if you get stuck in the joint can cause pain and swelling.

4.     Patellar Tendinitis: 

Your tendons are inflammatory if you have this condition. Tendon connects kneecaps with the shinbone. Overdo exercises can cause inflammation and sore. The most common cause is repetitive jumping; that is why it is also called “jumper’s knee.”Knee Pain - Types of Conditions

5.     Osgood-Schlatter Disease:

When you are young, the continuous change in your bones and other knee parts may cause this condition. When a tendon connects to the shin, it causes pain and bumps below the knee. This condition is prevalent in teenage boys and girls. Tibial tubercle sometimes makes the bottom of your knee hurt due to excessive exercise.

6.     Osteoarthritis:

The main cause of pain after the age of 50 is due to this condition. People suffering from this condition may feel stiffness in the morning. This type of arthritis causes wear and tears.

7.     Patellofemoral Pain Syndrome:

The main causes of this condition are muscle tightness, imbalance, and misalignment of the legs. If you are suffering from this syndrome, your legs can’t bear your legs and feel knee pain. This condition is more common in women and is not due to an injury.


Knee pain may cause many reasons depending upon age, activities, and injury. The first step you should take is to consult a pain management doctor. To know further about knee pain and its conditions, contact us at 646-862-5555 or book an appointment with our Pain Management Doctor.

Chronic Knee Pain

What is Knee Pain?

Knee pain is a very common complaint. Someone who is suffering from intense knee pain would notice swelling in their knees. Individuals from all ages can be the victims of chronic knee pain. Knee pain can be very irritating because it may hinder your routine activities. You will be unable to walk with ease. However, the effects of knee pain vary from person to person.

It is important to know about your knee structure. Your knee itself is a joint that holds together your thigh bone, shinbone and your knee cap. Ligaments also help connect the three firmly. Then, there is cartilage which is a fluid that lubricates and allows movement. The structure also has tendons.


The main cause of knee pain is injury. A bad accident or slipping usually results in a damage of the knee joint. The rupturing of your ligaments can also result in severe knee pain. Obesity is another factor that leads to unbearable knee pain. This is when your body weight increases excessively and your legs find it hard to carry all the weight as you stand.

Arthritis is one major cause of chronic knee pain. This is a condition in which one or both of your knee joints see abnormal inflammation, causing stiffness and pain. Sometimes, intense trauma (Such as: Traumatic injury while doing sports) leads to the dislocation of your knee cap. This makes it hard for you to walk or move your leg in any direction.

Another factor leading to knee pain could be, having a strained muscle. This problem may be fixed by doing a couple of knee exercises or getting a hot oil massage done. However, if still no relief is found, the sufferer must get in touch with a doctor.


Doctors prescribe pain killers for relief. Patients with arthritis need drugs with anti inflammatory properties that help lessen the swelling. In some cases, physical therapy sessions can be of great help as well. However, you have to be regular with these sessions to see an obvious improvement in your condition. In these sessions, the available staff will teach you exercises that apply to your condition and would help you heal. Other than that, your specialist will also give you a proper and detailed exercise plan.

Trying home remedies can also provide instant but short term relief. Yes, they can be a great help to nip the pain that’s causing discomfort, but you should visit a doctor as soon as possible too. Try keeping an ice pack on the swollen parts to get rid of the inflammation. You must also shed some weight and work on improving your eating habits. Cardio exercises and taking a walk at the park in the morning helps immensely. Do not walk too fast if your weight is causing pain in your needs and joints.


To conclude, it is always wise to get in touch with a doctor before your situation worsens. We can guide you and help you solve the problem after thorough examination. Do not suffer in silence, especially when the best help is not too far from you. You might not know the severity of your condition and what your symptoms maybe leading towards. We advise you to connect with us and schedule your appointment with the best Manhattan pain doctor.

Chronic Knee Pain, can Cortisone Shots Help?

cortisone-shots-chronic-knee-pain-nyc-doctor-01Studies have shown that the knee is one of the most vulnerable joints in the body. We all constantly use our knees. Walking, driving, riding a bike, or even just sitting at an office desk can put stress on our knees. Over time, our knees can develop pain. When people have knee pain, one of the first treatments they think of might be cortisone shots. But will cortisone shots help you? in order to answer that question, we first have to look at the anatomy of the knee, what causes knee pain, and how cortisone shots can help.

Knee Anatomy

medical-illustration-parts-of-knee-pain-02Functionally speaking, the knee is a fairly simple joint. As a comparison, look at the hip. our hips can move in three different planes; forward and back, sideways, and rotationally. Now, look at the knee. Then you can only do two movements, bending and straightening. This makes them very efficient and effective joints for the necessary daily task of walking. However, it also puts the knee in a particularly unprotected situation. If for some reason, a force is applied that would require the knee to move sideways or rotate, these movements are blocked by bony restrictions. if enough force is applied, these bones can break or cartilage can be degraded. Either situation also brings along pain and swelling. Additionally, the kneecap is held in place by ligaments. When under stress, these ligaments can stretch, tear, or even snap.

Causes of Knee Pain

The most common cause of knee pain is overuse. Many knee injuries happen while playing sports. Snowboarding, basketball, and soccer are all common culprits for causing knee pain. Knee pain can also simply be caused by repetitive motion or additional strain from lifting. Problems in the lower back, such sciatica, can cause a referred pain that is felt in the knee but originates elsewhere. Autoimmune disorders can cause swelling and inflammation of the knee for no apparent reason. Whatever the initial cause of the pain in the knee is, it can be difficult to give the knee time to heal. One common acronym to help people remember how to recover from an injury is RICE. This stands for rest, ice, compression, and elevation. Whenever we have knee pain, we might rush to get an ice pack, elevate our leg, or even put on a compression bandage. It’s hard to give the knee time to rest, though. Because it is so essential in such a basic skill, walking, we use our knees far more often than we think. This just draws out the amount of time it takes for our knees to heal from whatever injury we are dealing with. Additionally, bad posture at our workplace, in the car, or at home can put constant strain on the knees and make recovery even slower.

Cortisone Shots and Knee Pain

cortisone-shots-for-knee-pain-relief-top-nyc-pain-doctor-03Cortisone shots are a common treatment for relieving knee pain. Cortisone acts to reduce swelling, minimize pain, and assist with recovery. But cortisone shots are not the answer for all pain found in the knee. For example, referred pain caused from tight muscles in the lower back, poor body mechanics, or autoimmune disorders are not simply problems in the knee. Therefore, any relief found through cortisone shots would only be temporary. In order to really solve the problem, we would have to thoroughly discuss are symptoms with a doctor who is familiar with the affected area.

Are you dealing with knee pain? Call Dr. Grimm to make an appointment for a consultation to see if cortisone shots, or some other treatment, will help you.
