Knee pain, bike set up!

[sone]

I'm experiencing some knee pain across the front of my left knee whilst riding my road bike. Only a recent problem but it doesn't seem to be getting any easier. I've changed none of the set up on my bike so I'm a bit loss as to what could be causing the problem.
This leads to the question would a proper bike set up be a good investment and could it possibly help my issue. I've never had this done before so completely ignorant of the benefits. I'm not a competitive rider but would like my gear to do it's job without causing me grief.
Opinions would be appreciated.

Has the OP suddenly upped the mileage with the improving weather? Knees are sensitive things and just doing this with everything remaining the same (maybe some loss of muscle definition over winter if not having done much riding) could give some pain.

I have a partial tear to left ACL and no left MPFL. (Underside of patella is a mess)!

I've not really pushed on with mileage to be honest, I'm more governed by time than distance and like to ride for a couple of hours after work given the daylight at the moment.
I went for a ride last night and took particular care to keep my foot and knee well aligned, I don't know if this reveals an issue with my riding style but my knee definitely felt less stressed.

Thanks for input, it looks like a bike fit is worth a go, I mean what's to lose apart from a couple of hundred quid!

I'm going to take the plunge and get a bike fit done so thanks for advice but in the meantime I've been watching a view on line videos with regard saddle height. One particular method I looked at was the 109% method, that is a measurement taken from your groin utilising a book and a taper measure multiplying by 109% to give you the optimum saddle position when measured from the peddle at it's furthest reach. This all seems well and good but the same chap advises on one of his other videos that a saddle position can be approximated by sitting on your bike and just feathering the peddle with your heel again at it's longest reach.
My concern with these two methods and I've tried both give results that are 50mm apart! Doesn't seem to be very accurate is my conclusion or am I missing something.

Haven't got around to getting bike fit just yet but ironically I dropped my seat by about an inch to try and gain some comfort. Amazing thing is no more knee pain and I doubt very much if it is a coincidence as off the bike I'm still getting a few twinges as previous
Goes to show that just minor changes can have a major influence, I think I need to get the set up done properly who knows what other differences it could make.

Is this a serious post? An inch is a MASSIVE difference, I can tell the difference of a 2 or 3mm seatpost change.

Worrying.

Serious post yes! As I said in my opening post I'm not a competitive rider so worrying it's most definitely not.
