Knee injuries can be complex and multifaceted, often leading to a variety of symptoms and requiring different treatment approaches. Based on your description, it seems you have experienced a significant knee injury, which has resulted in swelling, changes in the knee's appearance, and functional limitations. Here’s a comprehensive overview of the symptoms, potential causes, and treatment options for knee injuries.


Symptoms of Knee Injuries
1. Swelling and Bruising: The presence of a hematoma (bruising) and swelling is common after a knee injury. This can occur due to bleeding within the joint or surrounding tissues.


2. Pain and Discomfort: While you mentioned that there was no initial pain, the inability to squat and the pain experienced after prolonged sitting suggest that there may be underlying issues, such as ligament or cartilage damage.

3. Joint Instability: The feeling of weakness or instability when standing up after sitting for a while can indicate that the knee joint is not functioning properly, possibly due to ligament injuries.

4. Changes in Knee Shape: The difference in appearance between your left and right knee could suggest swelling or structural changes, such as a possible misalignment or damage to the joint.

5. Limited Range of Motion: Difficulty in squatting and the sensation of tightness or weakness when trying to move the knee are significant indicators of potential injury.


Potential Causes
1. Ligament Injuries: Injuries to the ligaments, such as the anterior cruciate ligament (ACL) or medial collateral ligament (MCL), can lead to instability and swelling.

2. Meniscus Tears: The meniscus is a cartilage that acts as a cushion between your shinbone and thighbone. A tear can cause pain, swelling, and difficulty moving the knee.

3. Patellar Issues: Problems with the kneecap, such as dislocation or patellar tendinitis, can also lead to pain and functional limitations.

4. Bursitis: Inflammation of the bursae (small fluid-filled sacs that cushion the knee joint) can cause swelling and pain.


Treatment Options
1. Rest and Ice: Initially, it is crucial to rest the knee and apply ice to reduce swelling. Avoid activities that exacerbate the pain.

2. Compression and Elevation: Using a compression bandage can help manage swelling, and elevating the knee can assist in reducing fluid accumulation.

3. Physical Therapy: Engaging in physical therapy can help strengthen the muscles around the knee, improve flexibility, and restore function. A physical therapist can design a tailored rehabilitation program.

4. Medication: Non-steroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and reduce inflammation. However, if you have allergies to NSAIDs, consult your doctor for alternative pain relief options.

5. Imaging Studies: If symptoms persist, it may be necessary to undergo imaging studies such as X-rays or MRI to assess the extent of the injury and rule out fractures or significant ligament damage.

6. Surgical Intervention: In cases of severe ligament tears or meniscus injuries, surgical options such as arthroscopy may be considered to repair or reconstruct damaged structures.

7. Bracing: Depending on the severity of the injury, a knee brace may provide additional support and stability during the healing process.


Conclusion
Given your symptoms and the history of repeated injuries to the same area, it is advisable to seek medical evaluation from an orthopedic specialist. They can perform a thorough examination, possibly including imaging studies, to determine the exact nature of your injury and recommend an appropriate treatment plan. Early intervention is crucial to prevent long-term complications and to facilitate a full recovery, allowing you to return to your normal activities without pain or limitation.
