Hi, thanks for writing to HCM.
From the description, it seems that you have OVERUSE injury
of the ligaments and soft tissues of your knee joint owing to your prolonged and sternuous playing.
This could be managed primarily by the following means -
* Rest to the injured part and dont involve in activities which puts additional strain on the injured tissues.
* Ice packing should be applied for about 20 minutes once in every 2 hours.
* Use elastic compression bandage around the swollen area
* Elevation of the limb
& anti inflammatory medications
Honestly speaking, I don't think that you can get back to skiing.
Hope this information is helpful.
