Shallow knee groove?
« on: September 21, 2012, 04:28:23 PM »
Hiya all,

I am looking for some more information on having a shallow knee groove (trochlear) please.
Late last year I was told that I had a shallow knee groove. I have since had an MPFL Reconstruction for recurrent patella dislocations.
Since doing some digging, I have found that surgeries such as the MPFLr & TTT etc. aren't suitable for patients with a shallow knee groove- is this right?

Also if you have this, is there any way that you can manage it, or is surgery the only option to fix it?

Many thanks if advance,
Summer  :)

Are you still having dislocations? I have a shallow groove but never had dislocations until an accident permanently dislocated it.  :) I had a TTT and MPFL recon and now my kneecap is back in place and stays there. I never heard that those were not appropriate surgeries for trochlear dysplasia. I think if your dislocations are persistent and often surgery is the best bet.

Hiya RLE,

I haven't had another dislocation as of yet as my surgery was only 5 weeks ago, but my knee has been popping and shifting and as it is so mobile my physio is worried it could lead to more dislocations unfortunately.
I however didn't have a TTT, which at the time I felt that I should have had but my surgeon decided against it for the time being- although it seems that many people on this site have them both together.

Thank you for your reply, and Im glad that after your accident your surgeries were successful! I wish you all the best for the future!

I'm 5 weeks too and have had some popping. I think it's the ligaments stretching and getting into place. There are lots of phases in healing I know that from after my accident. I wouldn't worry about it.

Hi Summer

I have trochlear dysplasia as well with a shallow groove, I had an elmslie trilate on my left knee nearly 10 years ago which I think is one form of TTT and I haven't had a dislocation in that time, which after nearly 30 years of dislocations almost daily is a huge thing.I have just had an MPFL and TTO on my right, the MPFL to stop the dislocations which my OS has had a lot of success with. The TTO is because I also have patella alta and without that the MPFL would have been unsuccessful. I have every confidence that it will work as I know my OS specialises in trochlear dysplasia cases.

Hi Summer

I think we've come across each other before on the boards, so it should be Hi again! I have a domed trochlear and also have hypermobile joints which is why a ligament surgery (like a TTT) wouldn't really be suitable for me. I'm having a trochleoplasty on Thursday and will be updating my post op diary regularly.

Hope your knee recovers well and you don't have to consider any other surgeries!!

Hiya,

We have come across each other on the boards before, so hello again! Thank you for you reply. I am too hoping that there wont be a need for a further surgery, but I was interested in seeing what the facts were and also seeing if what I had read about was correct. I had only ever heard of a trochleoplasty working to correct a shallow knee groove- or atleast it has the best outcomes, although some surgeons dont like to do this surgery. Again, thank you very much for your reply, its greatly appreciated.

I wish you the best of luck with your surgery and your recovery and I hope that it all goes well! I will make sure to follow your post op diary to see how you are getting along.

Take care, Summer :)

A MPFL recon, in the absence of other anatomical problems (patella Alta, rotational problems, etc) has shown to be generally sufficient to correct trochlear dysplasia. And when I say correct, I mean stabalize the knee so that the trochlear dysplasia is no longer an issue.

Summer, I forget where you are located. The acceptance of trochleoplasties seems to be hit or miss across the world. It's probably the "newest" PF procedure out there (kind of guessing so, don't quote me on that) and results/opinions are mixed from what i've read. To point out Veganbee, she says she has a domed shaped groove, I think that is one of the "shapes" that the procedure has better results with. depending on where you are from, you may find an OS willing to discuss this procedure with you. 

Keep in mind, how procedures are combined is all about what is indicated. It's amazing at how individual our knees are. Some people like sasha below, had the TTT because they ALSO have patella alta. I for example did not, while my OS said I have a slight patella alta, it is not within her threshold to correct.

Hiya Allyd,

Thank you for your reply. I know that in general, if you dont have any other problems with your knee then the MPFLr is a very good surgery, with a high rate of sucess. The problem I had was that I do have some other problems and I feel that my OS didnt really consider this when he decided to do the surgery, but as he is very good I trusted him and went with what he had decided.
I am located in the South of England, and I think that this surgery is becoming more accepted- mainly on private registers though. I think that you are right about it being the newest procedure out there at the moment.

Again thank you for your reply. Take care, Summer :)
