I have studied your case. MRI
grade 3 MCL tear indicates severe injury
,you may need detail clinical evaluation.
MCL tear will lead to knee instability
Rest 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.
Partial tear can be managed conservatively with physiotherapy
with USG and TENS
Severe MCL tear may near surgical intervention.
