Hi Everyone,

just got my 2014 Boxster Base with manual transmission and overall it is a dream of a car! It has been a very long time since I had my last manual transmission car and in the past I never had an issues with manual transmission. Although, now after couple days of ownership with my Boxster, I have developed horrible knee pains in my left knee which are clearly caused by using the clutch. How are your experiences with Knee pain? If you had any pain, did it go away after a while or do I need to think to swap my car to a PDK? I would hate to do that, I love the car in the exact configuration and it took me a long time to find such a great deal. Any tips or advice would be highly appreciated.

thanks

Mike

I’ve never experienced knee pain from operating the clutch in my Boxster, so I have no direct experience to share with you. Generically, perhaps your seating position needs adjusting? When your foot is on the dead pedal to the left of the clutch pedal, there should be a slight bend in your leg, and then when you push the clutch in, your heel should just reach the floor, while the ball of your foot is solidly on the pedal.

Other than that, I got nothing.

Thanks for your answer. I am quite big, so there is not much I can adjust with the seat position. I am using your described technique but it does not help. I cross the fingers that the knee gets used to the new stress and after couple of days the pain goes away.

I’m no doctor, but I am a bicyclist and I’m thinking about adjusting a bicycle seat. The rider’s knee should never be fully extended. Is your knee fully extended when the pedal is fully depressed. If yes, you might try moving the seat forward a bit so that your knee remains slightly bent. Hope your car brings you more joy and less pain!

Sounds like you have meniscus damage that is catching on your knee joint at that angle. It's not the Porsche, it's your knee, I'm afraid. Sounds like you need Arthroscopic surgery to clean out the joint.

I sympathize with your knee pain problem. I'm getting old (71) and I've had a radical prostatectomy so I speak with some experience. Adjust your seat! Move in a little closer to the steering wheel. Lower or raise the seat until you find a sweet spot. (I used to ride bicycles so I agree with OCJoe.)

algiorda might have a good point too. You might need to see a doctor about your knees. Fortunately my knees still work but my hips are giving me hell.

If I get another Cayman or Boxster it will have PDK.

You didn't say how old you are, your health or what strenuous other physical activity you may be regularly doing, or what this level of pain is or ifyou have had pain in this knee before this.

I'm 72, driving manual trannys forever, and never any knee or hip joint pain. But I've also been into nutrition and supplements for 40+ years. I'm not a doctor. I found I was low in vitamin D 11 years ago and took 10,000 iu D3 per day for 2 years to get up into the normal range on the 25-Hydroxy-D test. Since then i take 5000 iu/day of D3 and my doctor says my D level is perfect. One large study found 62% of Americans to be deficient. That number is higher among people with darker skin, people living in northerly latitudes, and in older people. Deficiency, along with inadequate nutrional calcium and magnesium leads to many chronic joint diseases. For decades I've taken daily low dose aspirin and tumeric (usually capsules) for their anti-inflammatory effect. If experiencing joint pain, it's important not to ignore it. Quell it right away with naproxen sodium every 8 or 12 hours for a 10-14 days until the inflammation goes down. If it does not go away, don't ignore it or tough it out. You can do permanent damage to a joint if persisting in the physical activity. See a doctor.

Try using a knee brace to make sure your knee is flexing in the right plane. Then take a few long drives in heavy traffic.

Try adjusting your seat. Closer or farther away. The 981 clutch is pretty heavy. 991.2 is much much lighter.

I am recovering from rotator cuff surgery a couple of months ago - my right arm of course. That put a major damper on my driving pleasure since both of my Porsches are manuals.

However, it makes for fantastic physical therapy once I was out of my sling (mind and body).

Good luck.

The 981 does have a long and heavy clutch throw. That's a fact, and that may be exacerbating an existing problem. The suggestions to try different seating positions are good advice, and that may be all you need to do. If your knee pain persists, then something MAY be going on in the joint. A visit to an orthopedic specialist would be your next move, since he's the only one who can diagnose any issue and recommend a course of action. If it eventually comes down to the classic, “It only hurts when I do that,” “Well, don't do that,” conversation, a PDK may be the only choice going forward.

Thank you everyone for your responses. I have tried, as far as it was possible in the tight room, to change and adjust the seat position but it didnt help. I am really afraid that the pain will stay and it wont get better. I am giving it another 2-3 weeks and if it doesn't get better, I have to get rid of the car and go for a PDK one, even though it would be such a waste!!!

I had one of the first ‘Rabbit’ Diesels, no auto option and I really liked the mileage so got an additional Turbo Diesel Jetta, no auto option.
Never had knee pain but did get tired when in stop&go traffic.
My 2013 Boxster was ordered with PDK.
No pain, no tired leg.
Yes the 2.7 literally sings on the road and with Sport Chrono, a nice kick in the back on Track.
But to be concerned about re-sale?
Have you driven a Cayman?
My experience with the 981 Cayman is that they have a drone caused by the roof line extending back over the engine and thereby encapsulating the engine within the passenger compartment.
My Boxster is very quiet with the roof up.-Richard
BTW have your knee looked at by an Orthopedic Physician.
I’m not as good as some at diagnosing and recommending surgery and/or treatment on-line!

Getting the car that best suits you is definitely not a waste. PDK is no manual but it's still a lot of fun.

My left knee has been very touchy since sports in my early days. I have a PDK, but I find getting out of the car can put a lot of stress on my left knee if I can't swing the door open wide.

I drive the Boxster from Canada to Naples FL every year for the winter and my knee gets pretty tender after two 11 hour days.

As someone well versed in leg injuries, lol, I really encourage you to see an orthopedic specialist and have that knee examined and likely get an MRI. If you have a meniscus tear you need to stop it from getting worse, all the rest in the world will not help.

I got a PDK in part because of having a large tear (repaired and had great recovery) in my left knee and I didn't want to stress it further.

Thank you all again! I ll have my knee definitely checked.

I am still undecided, love the car but my health is more important. I had a very good deal on this car, paid for this 2014 CPO with sport suspension 32,5K which was 36K out of the door. The crazy thing about trading cars here in California (I think is different in other states) is that when you trade the car in, the tax/license is gone. That means even if my dealer would be willing to pay me back the selling price, I would loose the 3.5K I paid on tax/license. I checked with couple of dealers and they want to pay me for a car I paid 36k last week, 27k now!! Are you kidding me, one dealer told me they need to make at least 10-15% profit when they buy the car. I told him, he will make already profit when he sales the new car to me, but apparently they need to do double profit. This is just unbelievable!

What's cool in my state is the max sales tax on any car is something like $311. Sounds like you need to try to sell the car yourself?

I am not at all surprised by your experience! I have had only manual transmission cars in my entire life and I have never experienced such an hard clutch pedal as my 2015 boxster. Never had real knee pain for that, however I experience very tired left leg when my drive requires intense use of the clutch, i.e. heavy traffic.I guess I woud have knee pain too should I drive extensively for hours and hours in a single day.
Said that there is not a lot you can do, except as already said, adjust your seating position at best or driving minimizing shift changes as much as possible...
