Acl Reconstruction (Definition)

Because an acl (anterior cruciate ligament) cannot heal itself on its own, an acl is "reconstructed" by placing a graft tendon substitute (from your own or donor cadaver tendon) placed into tunnels made in the original acl position, and fixed in place with screws, buttons, or other fixation device. The body then replaces the cells and structure of the graft over 6-8 months, ...Read more

I keep having knee pain behind my knee 18 months post op. Acl reconstruction, what do I do?

Several reasons: When you tear your acl you not only injury the ligament but can also damage the joint capsule & joint surface. I would discuss this with your doctor to find out what was found out at surgery. In the interim I would suggest mild anti-inflammatories, ice it at night. Continue to stretch and do low impact exercises. ...Read more

Should be still feeling pain in your knee months post ACL reconstruction?

Not typically: Usually, the pain from surgery is one after the first few weeks. Pain after this period is more commonly associated with hamstring and pes tendinitis. This comes from quad weakness and poor quad control after surgery which takes time, effort, and patience to correct. Some patients can do this on their own with surgeon direction, others need formal physical therapy. ...Read more

Could you recommend a knee brace for ACL reconstruction patients?

Could you recommend a knee brace for ACL reconstruction patients?

Talk to your surgeon: Brace use after acl reconstruction is still controversial. Both immediate post-op bracing as well as eventual functional "sports" braces have questionable effectiveness. Most studies show no improvement in knee stability, re-injury rate, or healing time or rates with use of a brace. I still use braces most of the time, however, because subjectively patients feel better with the extra support. ...Read more

I have had an ACL reconstruction done in nov 2011. Is it ok for me to do yoga? Is it necessary to avoid bending knee beyond 90 degrees?

Shoul have full ROM: You should have full motion and relatively few restrictions at this point. Best to talk to your surgeon about what specific restrictions you should follow-often depends on associated pathology (meniscus, articular cartilage, other ligaments), graft type (auto vs allograft), and progression through prior phases of rehab. Also ask about using a derotational brace for activity. Good luck! ...Read more

I had ACL reconstruction 2 years ago and all week have increasing pain and my knee gives out. I haven't done sports lately what is wrong?

Time for a follow-up: Schedule a follow-up with your surgeon. It could be something as simple as persistent leg weakness, and a return to therapy could solve it. On the other hand, the integrity of the ACL graft should be checked by your surgeon. Many times other structures are injured at the same time as the ACL originally, such as meniscal tears or chondral defects, and so these may need to be re-evaluated. ...Read more

I had ACL reconstruction 5 years ago now have burning inside my knee. It feels like I put icy hot on it but I havent. Should I concerned?

Hamstring tendinitis: Most likely you still have quad weakness after your reconstruction.

You will still limp with your knee hyperextended when you walk longer periods. You'll have difficulty going down stairs, and you'll have burning down the leg to the calf in the evenings.

First, force yourself to stop limping. Second, work diligently on your quads (remember your exercises?)

you'll start improving within days! ...Read more

Yes.: Yes. If after an examination and probable MRI you are indeed diagnosed with an acl tear, surgery is an option. This will depend on your age, desired activity level, expectations, and other issues. Nonsurgical options exist as well, and this will/should be discussed by your doctor. ...Read more
