Swelling in the left knee with inability to bend?
Hello, Director Shi: Two months ago, I injured my knee while playing basketball.
I went to the hospital for an examination, where the doctor performed X-rays and an ultrasound.
At that time, there was no bone injury, but the doctor mentioned that there was some bruising in the ligaments.
After resting, I improved significantly and attempted to jog.
However, I experienced soreness behind my knee when squatting.
After feeling better, I returned to playing basketball, but I found that I couldn't exert force during lateral movements or turns, although I could still run straight.
This is the third time I have been injured due to such movements, and this time it seems more severe.
I would like to ask you, Director Shi, about my injury on August 3rd.
After the injury, I immediately applied ice and the next day I visited the hospital to see a doctor.
The doctor observed swelling in my knee, performed a drainage procedure, and ordered an MRI, but I have to wait five days to see the report.
The doctor initially suggested that there might be a cartilage tear.
I have to wait several days for a follow-up appointment, but currently, I cannot bend my knee without pain.
The doctor prescribed medication, and I am also applying ice myself.
I would like to know if there is a possibility of a ligament tear or cartilage rupture, how long I have to undergo surgery to avoid further damage.
Is there a critical time frame for this? My mobility is very limited right now, and I am quite worried about having to wait several days.
Please help me understand what I should do next.
Thank you.

Cartilage tears or ligament ruptures do not necessarily require immediate surgery.
Bones can be addressed within two weeks, while ligaments can be surgically treated within six weeks.
After an injury, it is important to rest and apply ice to reduce swelling in the knee joint, and then gradually restore joint mobility.

Hello! It sounds like you’ve been through quite a challenging time with your knee injury, and I understand your concerns about the swelling, limited mobility, and potential for further damage. Let’s break down your situation and discuss the implications of your injury, possible treatments, and recovery expectations.
From your description, it seems you’ve experienced a significant knee injury while playing basketball, which has led to swelling, pain, and difficulty with mobility. The fact that you initially had X-rays and ultrasound that showed no bone injury is a positive sign, but it doesn’t rule out soft tissue injuries, such as ligament or cartilage damage. The presence of bruising (hematoma) indicates that there was some bleeding in the area, which can occur with soft tissue injuries.
When it comes to knee injuries, the knee joint is indeed complex, consisting of bones, ligaments, tendons, and cartilage. The symptoms you’re experiencing—swelling, pain when bending, and difficulty with lateral movements—could suggest issues with the ligaments (such as the ACL or MCL) or the cartilage (such as a meniscus tear). The fact that you’ve had multiple injuries while performing lateral movements raises the concern that there may be underlying instability in the knee joint.
Regarding your question about the timing of surgery if there is a ligament tear or cartilage damage, it’s essential to understand that there is often a "golden window" for surgical intervention. For ligament injuries, particularly the ACL, surgery is typically recommended within a few weeks of the injury, especially if there is significant instability. Delaying surgery can lead to further joint damage and complications, such as arthritis. For cartilage injuries, the timing can vary based on the extent of the damage and the specific type of injury. In some cases, surgery may be necessary to repair or remove damaged cartilage, while in others, conservative management may be sufficient.
As you await your MRI results, it’s crucial to manage your symptoms effectively. Continue with ice therapy to reduce swelling and pain, and follow your doctor’s recommendations regarding medication. If you find that your knee is not improving or if your pain worsens, it’s essential to communicate this with your healthcare provider. They may consider early intervention based on your symptoms and MRI findings.
In the meantime, avoid activities that exacerbate your pain, particularly those involving lateral movements or sudden changes in direction. Gentle range-of-motion exercises can be beneficial, but they should be done cautiously and within a pain-free range. Physical therapy may also be recommended once you have a clearer understanding of the injury, as it can help strengthen the muscles around the knee and improve stability.
Lastly, while waiting for your follow-up appointment, keep a close eye on your symptoms. If you experience increased swelling, severe pain, or any signs of infection (such as fever or redness), seek medical attention promptly. It’s understandable to feel anxious about your recovery, but staying proactive and informed will help you navigate this process.
I hope this information helps clarify your situation and provides some reassurance as you await your follow-up appointment. Take care, and best wishes for a smooth recovery!
