<s>[INST] I damaged the MCL of my right knee 2 months ago, a week ago I could walk and bicycle without pain. 3 days ago I re-injured the MCL a bit more serverely. I am unable to put any pressure on that knee to hold during a left sided plank, however right sided plank is as normal. A crutch helps to get up and move around, but can limp without assistance after a minute. Wearing an elastic brace with metal side ribs for compression, support and to prevent re-injury. This time I expect more than a 2 month recovery. Is surgical intervention helpful or required? Bob [/INST] Hello, I have studied your case. You may need MRI to see grade of MCL tier will advise resting the part and avoid any movements that produce pain. Apply ice or a cold pack to the painful area for 15 to 20 minutes, 4 times a day for several days. Wrap the ice or cold pack in a towel. Till time, you can take anti-inflammatory and antibiotic if infection is suspected. If swelling and bruise is not reducing and giving pain while I will advise you to further investigate I will advise you to do MRI and Ultrasound of the swelling. Partial tear can be managed conservatively with physiotherapy with USG and TENS. There can be associated ACL injury. Grade 3 MCL may need surgery. Hope this answers your query.
