Hi, thanks for writing to HCM.
All your injuries (ACL, MCL, LCL & tibial plateau fracture
) indicate a significant damage to the Knee joint. There is no role of self care remedies for these sort of injuries and there is no way you can heal them by yourself.
You need to consult an orthopedic surgeon and based on the severity of injury
to the ligmanents and the bones, the treatment will be planned.
Hope this information is helpful. Good day
