Knee Injury After Accident: Pain and Limited Mobility - Orthopedics

Share to:

Knee deformity or genu valgum (knock-knees)?


Doctor, I was in a car accident and injured my knee.
Now, my knee cannot fully straighten, and it hurts a bit when I squat.
In the days immediately following the accident, my knee was very painful when I moved it inward, but it didn't hurt much when I moved it outward.
After a few days, it became difficult to fully straighten my knee, and I experience pain when squatting.
When I walk, my left leg has a slight wobble.
I'm really worried about my knee and I don't want my family to know.
What could be wrong with my knee?

Dr. Luo Zhongwei reply Orthopedics


Dear Wee: Your condition appears to be 1.
damage to the patellofemoral joint surface 2.
inability to fully extend the knee may indicate a tear in the meniscus, which requires arthroscopy for definitive diagnosis and treatment.

More Info


After a car accident, experiencing knee pain and limited mobility can be concerning, especially when the pain persists or worsens over time. Based on your description, it seems that you may be dealing with a combination of soft tissue injuries, potential ligament damage, or even issues related to the joint itself, such as inflammation or fluid accumulation.

When you mentioned that your knee does not straighten fully and that you experience pain when squatting, these symptoms could indicate several underlying issues. One possibility is a ligament injury, such as damage to the anterior cruciate ligament (ACL) or the posterior cruciate ligament (PCL). These ligaments are crucial for stabilizing the knee joint, and injuries can lead to pain, swelling, and difficulty with movement. The fact that you feel more pain when moving your knee inward suggests that there may be instability or strain on the ligaments when you attempt certain movements.

Additionally, the presence of swelling or fluid in the knee joint, which can occur after trauma, may contribute to your limited range of motion and discomfort. This condition, known as "joint effusion," can result from inflammation due to injury, and it often leads to a feeling of tightness or pressure in the knee. The pain you experience when squatting could be due to the strain placed on the knee joint and surrounding structures during that movement, especially if there is any underlying damage to the cartilage or ligaments.

It's also important to consider the possibility of a meniscus tear, which can occur during a twisting motion or impact. The menisci are cartilage structures that act as shock absorbers in the knee, and tears can lead to pain, swelling, and mechanical symptoms like locking or catching during movement.

Given that you have already experienced significant pain and limited mobility for some time, it is crucial to seek further evaluation from a healthcare professional. An orthopedic specialist can perform a thorough physical examination and may recommend imaging studies, such as an MRI, to assess the condition of your ligaments, cartilage, and any other structures within the knee joint. This will help determine the exact nature of your injury and guide appropriate treatment.

In the meantime, it is advisable to rest the affected knee, avoid activities that exacerbate the pain, and consider using ice to reduce swelling. Elevating the leg and using a compression bandage may also help alleviate discomfort. If you are experiencing significant pain, over-the-counter pain relievers may provide temporary relief, but be sure to consult with a healthcare provider before starting any medication.

Lastly, it's understandable to feel anxious about your injury and its implications for your recovery. It may be helpful to talk to someone you trust about your concerns, as sharing your feelings can alleviate some of the stress. Remember, seeking medical attention is a proactive step toward understanding your injury and working towards recovery. With appropriate care and rehabilitation, many knee injuries can heal effectively, allowing you to return to your normal activities.
