Hi meg,
I am sorry that you're facing these decisions. Catswold is right, surgery should only be done when all conservative treatments have failed. Even then, it is good to get several opinions.
Are you willing to travel?
As for the individual surgeries you mentioned, arthrocentesis is the first surgery most patients get. First the joint is numbed, then flushed with saline. Sometimes steroids are injected. The purpose of this procedure is to lubricate the joint, reduce inflammation, and/or increase function. If a surgeon tells you that this will decrease pain, I would be very skeptical. Also, some surgeons insist that this procedure can recapture the discs. I have yet to meet anyone who has recaptured discs with an arthrocentesis.
There are several reasons why an arthrocentesis is recommended for your first surgery...
1. It is the least invasive
2. It is done under iv sedation
3. It is done in the office
4. Recovery time is minimal (if there is any recovery at all)
5. It is cheap.
As with any surgery, there are disadvantages:
1. The surgeon cannot visualize the joint space therefore he does not know what is going on in there.
2. Disc recapturing is unlikely.
As for the second surgery, an arthroscopy, here are the advantages:
1. The surgeon can visualize the joint space
2. It is outpatient
3. Sometimes, surgeons say that they can recapture discs and suture them into place.
Disadvantages:
1. More expensive than the arthrocentesis (much more!)
2. The surgeon does not have much space to work with as he would in an open joint surgery.
3. The recovery is shorter and the scar is smaller than open joint surgery.
4. General anesthesia is required ($$)
there are studies that say the arthrocentesis is more successful than an arthroscopy. Many surgeons limit their practices to doing arthrocentesis, discectomy (open joint surgery with disc removal) and total joint replacements because those are the surgeries that they believe work best. In my opinion, the good surgeons are starting to phase out arthroscopy. If you have an mri and have seen what is going on, why go in and take a look??
The mitek anchor is a surgery that was done a little bit in the late 90's early 00's. I have met few people that have had it done... But the people I have met haven't had satisfactory results. I think that one should avoid placing any type of foreign substance in the joints for as long as possible.. Including titanium.
If the discs are in such bad shape, you might want to ask your surgeon - why not just remove them? Discectomy has proved to be a successful surgery especially in patients that do not have a problem with abundant scar tissue. However, this is seen as a more aggressive/drastic approach.
Although basically, you want to have as few surgeries as you can. If you can have one surgery and feel better, that is the goal. So in my opinion, sometimes you have to go more aggressive to get success.
Of course, these are all just my opinions. I hope that you won't need surgery at all! I have had arthrocentesis, arthroscopy, and arthroplasty.
Feel free to ask any questions.
I think the most important thing you said in your post was "most of my pain is muscular." before any surgery is done you must get a handle on the muscular problems, because if you don't, they will still be there after.
