All statins cause neurotoxic results in some form or other.
Some more than others, and also higher doses are worse as you'd expect.

But I do think that if you continue, you will have progression regardless of which statin you are taking.

Mostly compression of the peroneal nerve behind the knee, is from severe prolonged flexion...as in squats and kneeling. Paratroopers who land with parashutes can damage this nerve also behind the knee. Chronic leg crossing also compresses it.
People who are very thin, have little of the fat pad behind the knee which protects from various compressions.

Wearing knee braces that are too tight might also be a problem.

There are now doctors who study the toxicities of statins, and their risk profiles. Dr. Beatrice Golomb MD is one.
Here is one link to her--

If you search her or Dr. Graveline MD who is also a doctor and former astronaut you find alot to think about. Dr. Graveline lost his memory on Lipitor and has a lengthy website too.
Dr. Graveline's take on CoQ-10:

Also recently the FDA has forced statin makers to admit to other toxicities, such as raised blood sugars, and memory loss with statins. As time passes and more is learned I think we will see this family of drugs fade away. It is already beginning in fact.

Yes, you should be on CoQ-10... a quality type, with good absorption.
300mg at least a day. The drug companies knew this from the first statin marketed by Merck. They even took out a patent for a CoQ-10 and Lovastatin mixture. But back then they could not improve absorption of CoQ-10 in pill form so they dropped it, and kept the secret. It is only recently that this need was revealed.

There are newer better forms by Qunol company and this one

that are superior and would only need about 100mg a day.
Costco for example carries Qunol brand.

Normally CoQ-10 is not well absorbed from the GI tract, so with time
that hurdle has been lessened considerably.
