Knees are more fragile than people believe.
The constant burden of our weight makes these joints much more susceptible to injuries, abnormalities, and complications. These issues can become most apparent when we exacerbate the knees by kneeling.
The act of kneeling requires the intricate network of muscle, ligament, tendon, and bone to work in unison – any small disruption in the dynamics of these tissues upsets the knee and may trigger pain.
So what causes this pain and how can someone treat it once the issue is present?
In this article, we’ll explore some of the underlying causes of knee pain when kneeling, how to watch for signs that this issue is getting worse, and the treatment options available to an individual suffering from knee pain.
Anatomy of the Knee
The knee is a complex arrangement of soft tissues, bones, and muscles which are all extremely sensitive. If this intricate network of tissues is upset even slightly and it’s natural rhythm is thrown off, then complications could arise and eventually insight pain. This knee is made up of:
- Bones such as…
- The patella, more commonly referred to as the knee cap, helps extend the knee by increasing the leverage that certain tendons can exert on the lower leg.
- The femur, directly behind and above the kneecap, supports the weight of the human body allowing for motion of the leg.
- The fibula and tibia, directly under and adjacent to the patella, help stabilize the ankle and support the muscles of the lower leg
- Soft tissues such as…
- The medial and lateral meniscus, which are found on top and to either side of the tibia, absorb the impact of our weight on the knees.
- The posterior and anterior cruciate ligaments, located directly behind the knee, keep the knee centered, allowing for even distribution of weight across the meniscus and lower portions of the legs.
- The medial and lateral collateral ligaments, which overlap the end of the femur on either side, connect the muscles of the upper leg to the bone of the lower leg, control sideways motion of the knee, and brace it against unusual movement.
And, although they are not technically part of the knee joint, muscles such as the hamstrings and quadriceps provide the tension needed to insight the movements knees make. Abnormalities in these muscles can cause erratic movements in the knee, damaging the soft tissues and bones in the process.
If an individual is suffering from knee pain, it is likely due to the interaction between these components, past traumas they may have suffered, or degradation of the soft tissues which cushion the components from the crushing weight of the upper body.
Just as the tissues which make up the knee are varied and unique, so to are the possible underlying causes of knee pain when kneeling. Most of these issues can be traced back to one of two things, either a past injury or tissue deterioration, though these causal factors are not mutually exclusive.
Past Injuries and Knee Pain
The motion dynamics of the knee are very sensitive to change. If an individual endures some kind of trauma to their knee, these dynamics change, and knee problems begin to arise. Examples of a past trauma include:
- Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (MCL), and Medial Collateral Ligament (MCL) strains or tears.
- When any of the major ligaments of the knee are injured, they effect it’s natural stability, distribution of weight, and balance.
- Bone Fractures
- The kneecap is one of the most commonly injured bones in the human body. When such an injury occurs, due to the constant stress of the body’s weight, the bone will more than likely never make a full recovery.
- When the bones in the knee slip out of place, pain can be immediate. Once a dislocation occurs, the likelihood of another such episode increases, causing more and more pain as an individual ages.
After these traumas take place, they may be accompanied by pain due to the new biodynamics within the knee. Nerves may be pinched, bone can begin to rub against bone, and muscles can swell and become inflamed.
Tissue Deterioration and Knee Pain
Deteriorated tissue is one of the most common causes of knee pain when kneeling. As the soft tissues in the knee degrade, so to do their cushioning effects.
This lack of cushion can cause a number of problems which ultimately cause us to feel pain as we exert force on the knee.
Some of the most common issues with tissue deterioration and the knee are:
- Osteoarthritis of the knee is a common condition, especially as we age. As we age, and the cartilage in our joints wears away due to everyday movement. As the cartilage wear away the joints, especially the load-bearing joints such as the knee, can become stiff, swell, and develop pain.
- Patellar tendonitis
- Characterized by inflammation of the tendon which connects the kneecap to the shin bone, patellar tendonitis is a product of repeated high-intensity stress on the knee. Patellar tendonitis most often occurs in athletes, especially those whose sport of choice involves jumping, but can occur in most anyone.
Signs and Symptoms
Though determining the underlying cause may be difficult, diagnosing knee pain is simple. The most common signs of knee trouble are:
- Swelling and stiffness
- Redness and warmth to the touch
- Popping, cracking, or crunching noises
- An inability to fully straighten the knee
Experiencing any of these issues may be an indication that an individual’s knee pain when kneeling is something much larger, especially if these symptoms occur under minimal physical excursion. If these symptoms occur frequently and are accompanied by pain, it may be time to consult a doctor.
After setting up a consultation and discussing the types of knee issues you are experiencing, a physician will use various diagnostic methods to deduce the exact issue. These include, but are not limited to:
1. Physical Examination
A consultation will usually lead to a physical examination of the area of pain. The doctor may begin by palpating (applying pressure to various portions) of the knee to see which portions elicit a pain response. By finding the points which provoke pain, a doctor will have a better understanding of which portions of the knee may be at risk.
2. Drawer test
Another part of the initial clinical assessment of the knee involves what is known as a drawer test. Drawer tests are most commonly used when the doctor suspects that a ligament has been torn or is ruptured.
The patient will be asked to lay on their back while bending their knee and placing their foot flat on the examination table. By applying pressure directly under the kneecap with both thumbs, doctors can get a better idea of the state of the ligaments in the knee. If the tibia pulls forward or backward more than expected, the test is considered positive.
3. Valgus Test
Similar to drawer test, a valgus test begins with the patient laying on their backside on an examination table. The doctor will ask the patient to relax their knee as they angle the lower leg towards and away from the center of the body. By applying stress to the knee in this fashion, the doctor can examine the state of the MCL and LCL. If the knee is seen to open too far on either end, or if the patient experiences an abnormal amount of pain, this usually indicates that one or the other ligament may have sustained some damage.
X-rays give doctors a good indication of abnormalities in the structure of the bones in the knee. Using X-ray technology, doctors are able to access knee alignment, bone quality, and the extent of any degenerative bone illnesses within the knee. Doctors can also use X-rays to inspect past traumas and fractures, the quality of some of the soft tissues of the knee, and any abnormalities in the spaces between the major bones of the knee.
Magnetic resonance imaging (MRI) of the knee uses magnetic fields and radio waves to produce a detailed picture of the bones, ligaments, cartilage, tendons, muscles and blood vessels of the knee from different angles. By examining these structures and how they change over time, a doctor can deduce the impact of degenerative illnesses, the progression of bone fractures or other tissue injury, and complications related to any treatment methods being used.
A non-invasive method of looking inside the body, arthroscopy involves a minor incision followed by the insertion of a small camera into the knee. Using an arthroscope, a doctor can see visuals of the inside of the knee, detect problems, and may even be able to correct small issues using tiny instruments within the arthroscope.
A doctor may choose to use one or more of these techniques to investigate the underlying causes of your knee pain. Once they’ve found the root issue or issues, they will develop a treatment plan catered to the patient’s specific needs. Some patients may be under time constraints, other’s care more about reducing pain, and some have minimal functional goals they’d like to reach. Whatever the case may be, doctors have a variety of tools at their disposal to create a treatment plan which suits the needs of their patient.
There is a wide variety of conventional treatment methods to help a patient reach their functional goals if they are experiencing knee pain when kneeling. Conventional treatment options have so far been the most recommended and widely studied methods. Below are some of the most popular methods doctors will try.
1. RICE therapy
Some knee issues may be as simple to treat as rest, ice, compress, and elevate. The RICE method is typically recommended at the onset of treatment due to it’s simplicity, though it may often be recommended during flare-ups to ease the pain and reduce the swelling an individual may experience.
Medication is an immediate solution to the pain an individual may experience due to their knee issues. While this form of treatment doesn’t solve the underlying causes of knee pain, it does provide immediate relief to the issue. If the pain is a minimal disturbance, doctors will typically recommend over the counter pain relief such as acetaminophen, ibuprofen, and naproxen. If the pain is debilitating, doctors can prescribe stronger medication, though these come with their own risks. Stronger medications can become addicting, may degenerate tissue further, and their effects are known to wane overtime, leading to stronger and stronger dosages and the potential risk of liver damage.
3. Physical Therapy
Another popular treatment option is physical therapy. Physical therapy helps individuals restructure their body’s biomechanics. By emphasizing the use of lateral muscles and boosting their strength, physical trainers can help reduce the pain an individual feels throughout their everyday motions.
4. Steroid Injections
There are a host of steroids that a doctor may recommend for treatment. These injections act quickly by reducing inflammation and as a result the pain an individual may feel. While steroid injections aren’t the first option for treatment, they are still popular some of the most popular treatment methods throughout the United States. In recent studies, steroid injections have been shown to degenerate tissues further, thus increasing the magnitude of the pain an individual may feel. Overtime, steroid injections run the risk of causing debilitating pain and even permanent damage to the area they are meant to treat.
Surgery is often a last resort for individuals. Long recovery periods, expensive medical bills, and minute success rates make surgery impractical solution for knee pain treatment.
6. Regenerative Therapy
Though regenerative therapies have been around since the 1970’s, recent advancements in regenerative sciences have popularized these treatments across the globe. Previously, Platelet Rich Plasma, or PRP, therapy was seen as a radical and expensive treatment method for joint pain. Advancements in this medical science have made the cost more reasonable as well the therapy itself more widely available. In addition to PRP, a development in stem cell science has created a new market for stem cell therapies in treating tissue damage.
Both PRP and stem cell therapies work in a similar way. Doctors extract tissues directly from the patient’s body, process them, and then reinject them into the site of injury. These cells then create a suitable environment for tissue repair by calling the body’s natural healing factors to the site of injury. These healing factors, coupled with chemical signals from the PRP and stem cells, can rebuild and repair damaged tissue, thereby restoring function to the knee.
These treatment methods are being widely studied and have become more accepted as an alternative treatment to not only joint issues, but soft tissue, muscle, and even bone damage.
Knee pain while kneeling may be an indication of a much larger issue. With so many intricate pieces at play in the knee, even a single dysfunction can have a massive impact on the overall biomechanics of the knee.
Conventional treatment methods may be ideal for some, but for others, the process is time consuming, costly, and often ineffective. When coupled with alternative treatment methods such as regenerative therapies, the effects of conventional treatment options may be heightened.
PRP and stem cell therapies alone may be enough to help an individual reach their functional goals in regards to the knee. For a consultation and to learn more about these radical, non-invasive treatment methods, contact the CELLAXYS offices today.
