Causes of Knee Pain
There are many different causes for knee pain, ranging from sports injuries and arthritis to excess weight.
Knee Pain Caused by Sports Injuries and Accidents
Accidents happen in sports and in everyday life. Here’s a list of the most common knee injuries that can occur from sports injuries and other accidents.
ACL Injury
ACL stands for the anterior cruciate ligament, one of four major ligaments in the knee joint. Located in the middle of the knee, the ACL is responsible for stabilizing the knee and preventing the sliding of the tibia under the femur.
An ACL injury is one of the most common sports injuries in athletes who play sports that involve sudden changes in direction. Soccer players and basketball players often need knee surgery due to an ACL injury.
Fracture
It’s possible to break the bones of the knee (including the kneecap) in an injury, such as a car crash, a fall, or a sports injury. It’s also possible to break knee bones as a result of osteoporosis.
Knee Bursitis
Sometimes knee pain is caused by inflammation in the bursae, fluid-like sacs in the knee that help the tendons and ligaments glide smoothly over the joint. A wide variety of injuries can cause this type of inflammation in the knee.
Patellar Tendinitis
Patellar tendinitis is irritation and inflammation in the patellar tendon that connects the shinbone to the quadriceps muscle on the front of the thigh. This type of knee injury is common in cyclists, runners, and skiers. We also see patellar tendinitis occur in athletes involved in jumping sports.
Torn Meniscus
It’s possible to tear your meniscus if you suddenly twist your knee. The meniscus is a piece of cartilage that helps to absorb shock inside the joint.
Knee Pain from Mechanical Issues
Sometimes simply moving the wrong way can cause an injury to the knee. Here are some of the mechanical issues associated with knee pain:
Dislocated Kneecap
It’s very painful to dislocate a kneecap. This happens when the patella, a triangular bone that covers the front of your knee, comes out of place. Most often, the bone slides to the outside of your knee. It’s common to see a dislocated kneecap.
Foot or Hip Pain
In some cases, you can experience knee pain due to foot or hip pain that makes you walk differently to avoid pain in those areas. Unfortunately, this change in the way you walk might add more stress to your knee and cause pain.
Iliotibial Band Syndrome
Iliotibial band syndrome happens to distance runners and cyclists. It happens when the iliotibial band, the band of tissue from the outside of your knee to the outside of your hip, tightens and rubs against the outside of your femur.
Loose Body
In some cases, a piece of cartilage or bone can break off and float into the knee joint where it causes pain.
Arthritis-related Knee Pain
A lot of time, knee pain is caused by arthritis. There are different types of arthritis that can cause knee pain. Here are the most common:
Gout
Gout is a type of arthritis that can cause pain in the knees. It is the result of high levels of uric acid that forms sharp crystals. These crystals can cause pain along with swelling and tenderness.
Osteoarthritis
Another type of arthritis that affects the knee is osteoarthritis. While initial symptoms might be mild, eventually osteoarthritis can cause severe knee pain that requires knee surgery.
Pseudogout
The joint that is most commonly affected by pseudogout is the knee. This type of arthritis causes sudden, painful swelling in the knee.
Rheumatoid arthritis
Rheumatoid arthritis affects your joints, including the knee joint. It causes pain, stiffness, and swelling that can have a negative impact on your daily life. Knee surgery might be an option for people who want to reduce joint pain and improve their daily life.
Septic arthritis
The knees are one of the most commonly affected joints in septic arthritis. This type of arthritis is an infection in the joint that causes a lot of pain. It has the ability to cause damage to the cartilage and bone inside of the joint, which makes prompt diagnoses and knee pain treatment very important.
Additional Problems with Knee Pain
In addition to injuries, mechanical problems, and arthritis-related knee pain, there are other reasons you might be experiencing pain in your knees.
Factors such as excess weight, lack of muscle strength, and previous injuries can all increase your risk of having knee issues and pain.
Diagnosis
If you are experiencing knee pain, it’s important to listen to your body and have a healthcare provider check your symptoms.
At Complete Orthropedics, our orthopedic knee doctors provide consultation and diagnoses of common issues that cause knee pain. In most cases, we’re able to diagnose your case in the office during your first visit.
The Process
We conduct a formal history and physical examination. During the exam, we have a thorough discussion with you about your knee pain, its duration, characteristics and exacerbating or alleviating factors. We also check your knee for visible symptoms, check how far you can move your leg, and push or pull on the joints to see the integrity of the knee.
Next, we conduct any related tests that apply to your situation, including x-rays. If we’re still unable to diagnose your problem, we can then order additional tests such as a CT or MRI scans.
Treatment and Surgery
Your knee pain treatment will depend on your diagnosis. There are many non-surgical treatments for knee pain, including physical therapy, injections, as well as home remedies and alternative medicine options.

However, in some cases, you may require a knee operation to treat your knee pain. If you require knee surgery, we can help you decide whether you need to have the surgery right away or at a time that best meets your needs.
Some of the most common surgeries associated with knee pain repair include:
- ACL surgery
- Arthroscopic surgery
- Partial knee replacement surgery
- Total knee replacement surgery
1. ACL Surgery
We offer ACL surgery for people who have experienced an ACL injury. In many cases, knee surgery on young patients with high activity levels that help them to return to their normal life or preinjury activity level and lifestyle.
2. Arthroscopic Surgery
We provide arthroscopic surgery for knee pain. Depending on your diagnosis, we might repair your knee using a fiber-optic camera and long, narrow tools. Using this method, we can reconstruct torn ligaments, remove loose bodies, and remove or repair damaged cartilage.
3. Partial Knee Replacement Surgery
In some cases, you might require a partial knee replacement surgery. In this type of surgery, we replace only the damaged part of your knee and replace it with new parts made of metal and plastic. This relatively minor surgery is done through small incisions and has a faster recovery time than a total knee replacement.
4. Total Knee Replacement Surgery
If you require a total knee replacement, rest assured you’re in good hands with the surgeons at Complete Orthopedics. This is our most common procedure. In this knee operation, we replace the damaged parts of the knee joint with metal and plastic parts.
The metal parts are made of cobalt chromium alloy. The femoral component replaces the lower end of the femur and requires making special cuts on the bone for the prosthetic implant to fit snugly. The above image shows a posterior stabilized femoral component which requires sacrifice of the posterior cruciate ligament. The ligament function is reproduced by the polyethylene insert which fits in the tibial component in the image above. Together the parts reduplicate the function of the normal knee.
The modular components are used in revision knee replacement and complex knee replacement surgery. The components allow the surgeon to make intraoperative changes to achieve greater stability according to the patient’s anatomy and bone loss. The stem attaches to the upper part of the modular femoral component. While the femoral component is cemented to the lower part of the thigh bone, the stem is not cemented.
The above images show modular tibial component along with bone augments. The bone augments are used to fill in the bone gaps encountered during surgery. The stem helps to stabilize the tibial component in the shin bone.
Recovery
Your recovery plan will depend on the type of surgery that you receive.
