Common Causes of Knee Pain

Knee pain often manifests itself in the form of pain accompanied by swelling and stiffness in the knee joint, weakness or instability, popping noises, and an inability to straighten the knee. Knee pain and stiffness can come and go and some days may be more painful than the others. This can severely affect the patient’s mobility and have an adverse effect on their lifestyle. Some of the most common causes of knee pain include:

  • Acute injuries such as strains, falls, accidents, or sports injuries.
  • Arthritis of the knee including osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis.
  • Overuse of the knee joint through repetitive physical motion and activities, playing sports and exercise.

How to relieve knee pain?

Since knee pain can affect a person’s mobility, it is prudent for them to seek some knee pain remedy in order to return back to their normal routine and lifestyle as early as possible. There are certain knee pain relief remedies that one can do at home to see if the pain responds. If not, it is a good idea to get yourself checked by a qualified knee pain specialist in Singapore for effective diagnosis and treatment for knee pain.

Home remedies for knee pain

Probably the most effective way on how to heal knee pain at home is to utilise the RICE (Rest, Ice, Compression, Elevation) protocol. Giving your affected knee the required rest by avoiding activities that put strain on the knee is crucial to ensure recovery. Applying ice on the affected knee for 15-20 minutes three times a day helps reduce inflammation and pain. Applying a pressure bandage on the knee and compressing it is also beneficial for knee pain relief. Finally, elevating your knee above the heart level while lying down by propping it over a few pillows also helps manage inflammation and pain.

Exercises for knee pain relief

Although resting the affected knee is important during the initial days of injury, it can stiffen the joint and contribute towards a slower recovery. Daily exercise can help keep the muscles strong and the joint flexible so that your mobility is not affected. After consultation with your doctor or physiotherapist, you can engage in low-impact exercises such as walking, cycling, swimming, and yoga.

Signs Your Knee Pain Needs Medical Attention

Although some simple cases of knee pain may be treated at home with remedies, there are certain injuries and situations where it is important to consult a professional for correct diagnosis and consequent treatment. Do visit your nearest healthcare provider in Singapore if you experience the following signs and symptoms:

  • Persistent knee pain that does not respond to home remedies
  • Severe knee pain that affects your daily activities and routine
  • Knee swelling
  • Fever accompanied by knee pain, swelling, and redness
  • You can’t bear weight on your knee or feel weakness and instability in the knee
  • Hear a popping noise from the knee
  • Your knee feels red and warm to touch

Do I Need A Diagnostic Imaging Scan?

In addition to a physical exam by the doctor, you may need diagnostic imaging scans for knee pain diagnosis and treatment. This is because imaging scans can help doctors visualise the internal structures of the knee including the joint bones, ligaments, muscles, and other connective tissues. Through these scans, the doctor can be in a better position to identify any injury to any of the internal structures of the knee and recommend treatment accordingly.

Types of Diagnostic Imaging for Knee Pain

The diagnostic imaging scans used for knee pain diagnosis in Singapore include:

  • X-rays — X-rays are used to visualise the bones of the body. Through an x-ray of the knee, a doctor is able to detect bone fractures and degenerative joint disease.
  • CT Scans — CT Scans use x-rays from different angles to get cross sectional 3D images of the internet structures. A CT scan uses more sophisticated and advanced technology than a traditional x-ray and is able to pick up bone problems, subtle fractures, and gout.
  • MRIs — An MRI uses radio waves and a strong magnet to create clear and detailed 3D images of the inside of the body. It is a non-invasive way of viewing organs, soft tissues, bone and other internal body structures. An MRI scan for knee pain can help identify injuries to the soft tissues of the knee including ligaments, tendons, cartilage, and muscles. Other health issues that require the use of MRI scans include breast lumps and chronic back pain.
  • Ultrasound — An ultrasound uses sound waves to generate real-time images of the knee structures and can help identify knee injuries related to the soft tissues.

Although many thought they share the same purpose, CT and MRI scans have different modes of action and structure visualisation. Check out this article to learn more about MRI scan vs CT scan.

Advanced Knee Pain Treatment Options

Knee joint pain treatment in Singapore involves non-surgical and surgical treatment options depending on the underlying cause of knee pain.

Non-surgical

As a first line of treatment, your doctor may prescribe some of the following non-surgical treatment options for knee pain.

Medication

Knee pain medicine that includes over-the-counter painkillers and NSAIDs (non-steroidal anti-inflammatory drugs) are helpful in managing pain and swelling. Tylenol, ibuprofen, naproxen, and aspirin are some of the painkillers that are taken for knee pain management. Always consult your doctor before taking any medications.

Injections

Your doctor may recommend a type of injection to be administered directly into your knee joint to manage pain and swelling. These injections can include Corticosteroids, Platelet-rich plasma (PRP), or Hyaluronic acid injections.

Physical Therapy

Physical therapy is an important modality in any kind of knee pain treatment as therapy strengthens the knee muscles, makes it more stable, and aids in recovery. Your physical therapist will guide you in doing the right exercises, stretches, and low-impact activities that can help you manage knee pain and help your knee recover better.

Surgical

In some cases of knee injuries, surgery might be the only option. Surgery may also be essential if all conservative measures have been exhausted with little to no improvement in the knee pain. Surgical treatment options for knee pain in Singapore may comprise the following procedures:

Arthroscopic Surgery

In arthroscopic surgery, a few small incisions are made in the knee. A thin, fibre-optic camera is inserted into one of the incisions that helps visualise the internal area. Thin surgical tools are then inserted through the other incisions. The video feed from the camera guides the surgeon in carrying out the surgical procedure. During a knee arthroscopy, the surgeon removes damaged cartilages from the knee joint and may repair or reconstruct damaged cartilages and torn ligaments.

Osteotomy

Osteotomy is a surgical procedure that can help relieve knee pain associated with arthritis. During this procedure, the surgeon removes a part of the thigh bone or the shin bone to align the knee better.

Partial Knee Replacement

In a partial knee replacement surgery, the surgeon removes only the damaged parts of your knee and replaces them with metallic or plastic parts. This surgery is usually performed through small incisions made in the knee.

Total Knee Replacement

In a total knee replacement surgery, the surgeon removes the entire knee joint, knee cap, part of the shin bone and thigh bone, and all other damaged ligaments and cartilages. He then replaces all these parts by an artificial knee joint made out of metal alloys, polymers, and high-grade plastics.

How to Prevent Knee Pain

You may not always be able to prevent knee pain, especially the one associated with arthritis or an injury. However, there are certain precautions and preventive measures that you can take to strengthen your knee muscles and prevent injury of the knee.

  • Weight management is the most important tip to prevent knee pain. Excessive weight puts a lot of pressure on the knees, increasing the chance of damage to the knee structures and pain.
  • Stretch and warm up before doing any physical activity or exercise. Similarly, cooling down and stretching after a physical activity is also crucial.
  • Do strengthening exercises to strengthen the knee muscles.
  • Wear proper footwear that puts minimum strain on your knees.
