Knee buckling?

I use to play high school sports and it really messed up my body. Today my knee buckles upwards of 10 times a day. I will be walking and it will just give out and I will fall. It is almost as if my leg were missing. I cannot be standing or walking for too long before my knees and ankles start to hurt. Is there anything I can do?

It sounds like you have a sagittal plane deformity with a diagnosis of genu recurvatumn and should seek an orthopedic evaluation and treatment options

Follow this link. There is a very simple and pain free decompression treatment that does wonders for the knee.
I recommend you make an appointment with a foot and ankle surgeon (podiatrist) for diagnosis, cause and treatment options for your case. I also recommend you make an appointment with an orthopedic surgeon for evaluation of your knee
definitely need a consult with orthopedics doctor. This is a condition that requires a medical workup like xrays, gait exam, evaluation of other joints, etc.
It sounds like you are having a problem with one of the collateral ligaments around the knee and/or one of the cruciate ligaments in your knee. You need to seek the help of an orthopedic specialist who focuses on the knee and likely will need an MRI and quite likely will need surgery to repair those ligaments. Podiatrists do not work on the knee-only up to the knee, so I am not an expert in this area, but I know that this is the correct answer to your question.
Knee buckling is the perception that the knee is giving out. We call
this knee instability.

The reasons for instability are many:meniscus & cartilage tears,
ligament injuries (torn ACL/ PCL or MCL), articular loose bodies &
patellar instability, as well as muscular & neurologic issues.

Although some instability may resolve on its own, I recommend a thorough
evaluation. If indicated, this may include MRI to evaluate internal knee
structures. You didn’t mention your chosen sport. Although knee injury
may occur in any athletic activity, significant knee injuries are
extremely common in girls’ soccer, making evaluation more important.
I may have an ACL tear. I need to see an orthopedic surgeon.
Good morning and thanks for sharing your knee problem with the FATD team. I appreciate your share and would like to offer you my thoughts, tips and suggestions about this problem.

You are not alone. So many young athletes love their sports but their bodies get damaged and these issues sometimes leave them with ‘permanent’ alterations to their joints and bodies. Do you remember one specific injury or accident that affected the troublesome knee?

When I think of ‘buckling’ and giving way of a knee, I think about stability and therefore ligaments (the small rope-like structures that connect one bone to the other). By far the most common knee ligament to give feelings of instability is the ACL (anterior cruciate ligament).

The best way to understand your knee issue is through a good history and physical by a sports medicine-trained orthopedic surgeon (or orthopedic doctor). They may also get X-rays and an MRI scan to help understand what is going inside the knee.

I encourage you to stay positive but also seek help from a doctor like the one I mentioned above, because a chronically unstable knee (or feelings like that) can lead to early onset knee tissue breakdown and painful degeneration (that is called arthritis).

I hope this helps.
You should have imaging done of the affected joints to know the internal condition, along with an orthopedic exam. Then, if the imaging and exam are negative for any problems, start resistance exercises for the thigh and leg muscles. I would recommend at that time, to have a personal trainer with knowledge and experience in strengthening these muscles and tendons. First, make sure you are okay though before resistance exercises are started.
Your symptom description is suggestive of an ACL tear. You need to see an orthopedic surgeon and will likely require surgical repair. Meanwhile, I will recommend wearing a hinged knee brace.
Hi,
At your age, buckling can be a symptom of meniscus tear, patellofemoral problems, or ligament tear. Ligament tears are usually have a history of a significant knee injury with swelling and a recovery time of 3-12 weeks. Meniscus problems at your age usually follow injury as well. With meniscus tears, the knee may become stiff or swollen following giving way, and there may be point tenderness at the edge of the top of the tibia on either side. Giving way due to patellofemoral problems is more common in females, and typically happens going down stairs or inclines. Less common causes include osteochondritis dessicans, where a portion of the bone dies, loose bodies and muscle weakness.

Evaluation starts with xrays and exam. Patellofemoral problems often respond to physical therapy and exercise. Meniscus and ligament tears may require surgery. MRI is useful if the symptoms have been present for >3 months or physical exam findings suggest meniscus or ligament problem.

Goal at your age is to get back to full activity. Long term patients that stay active with good muscle tone and normal body weight do best over time.
There are a variety of things that can lead to the feeling of your knee buckling. I would encourage you to find a local orthopedic surgeon to have it looked at.
