Knee Pain Service
Knee pain is a common symptom that affects people of all age groups. It may result from:
- Injury (strained ligament or torn cartilage)
- Rheumatoid arthritis
Minor knee pain responds well to rest and anti-inflammatories. Additionally, physical therapy and knee braces also can help to alleviate knee pain.
In more severe cases, however, you may require steroid injection, PRP, hyaluronan replacement, surgical knee repair or knee replacement.
Location and severity will depend on the cause of the knee pain. Additional signs and symptoms that may occur with knee pain are:
- Swelling and stiffness
- Redness and warm to the touch
- A sensation of weakness or instability
- Popping, clicking or crunching noises
- The inability to fully extend or flex the knee
Call your doctor if you:
- Are unable bear weight on your knee or feel as if your knee giving out (unstable)
- Have a lot of swelling in the knee
- Are unable to fully extend or flex your knee
- See a deformity on the knee, or on the upper or lower leg
- If you have a fever in addition to pain, redness and swelling
- Have severe knee pain that is present after trauma
Knee pain can be due to trauma, mechanical problems, arthritis and other issues.
Trauma to the knee can affect the bones, cartilage, ligaments and the sacs filled with fluid that surround it (bursae). Some common knee injuries are:
Anterior cruciate ligament (ACL) injury. This is a tear of the anterior cruciate ligament (ACL), one of four ligaments that connect the shinbone to the thighbone. An ACL injury is particularly common in people who play sports in which there is a lot of sudden change of direction such as basketball or football (soccer).
Fractures. The bones of the knee, including the patella (kneecap), can be broken during car accidents or falls. Those with osteoporosis can sometimes sustain a knee fracture simply by stepping improperly because the bones are weaker due to the reduced density.
Torn meniscus. The meniscus is a tough rubbery cartilage that functions as a shock absorber between your thighbone and shinbone. If you suddenly twist your knee while bearing weight on it, it can tear.
Knee bursitis. Some knee injuries can lead to inflammation in the bursae, the sacs of fluid that cushion the outside of your knee so tendons and ligaments can glide smoothly over it.
Patellar tendinitis. Tendons are thick, fibrous tissues that attach muscles to bones. When they get irritated and inflamed, that is known as a “tendintis”. Runners, cyclists, and those involved in jumping activities may develop inflammation in the patellar tendon (kneecap), which connects the large quadriceps muscle at the front of the thigh to the top of the shinbone (tibia).
