ACL Reconstruction - Two weeks later

I had my ACL reconstruction two weeks ago exactly. I had a hamstring graft and all has been well until today. Today was my first day back at work, which involves commuting to work and a total of about 30 mins walking each way. Walking to work today has been fine, but on the way back, I noticed a "plucking" sensation on the outside of my left (operated) knee about 5 out of every 10 steps. Could anyone advise what this may be? I think my knee has swollen slightly about the knee cap but not drastically (probably a reaction to walking a bit more), but the plucking feeling (like a guitar string) is a bit unnerving. I dont think there has been another tear but could this be the graft becoming loose? i.e. one of the screws?

Many thanks for your time,

Hi

Unlikely to be one of the screws. Do you know which hamstring muscle they used?? One of your hamstring tendons attaches to the outside of your knee. One of the post operative issues with ACL reconstruction is scarring. Not only from the damage done by the injury but also as a result of taking muscle tissue from your hamstring. As they cut through skin for the surgery you can also get a bit of adhesion/scarring from that - mostly around the surgery sites/scars.

The other possibility (and also quite common) is a condition called patellofemoral syndrome. This can often occur after an ACL reconstruction. Basically your patella (kneecap) gets "stiff" and doesn't glide properly when you are walking. This is due to a combination of inactivity prior to the surgery, muscle weakness from the injury and the wait for surgery, and the resulting inflammation and scarring from the surgery and the injury. Usually some treatment around your kneecap sorts this out quickly. You can also use strapping tape to hold your kneecap in a better postion so you don't get that sensation when you walk. Once you have strengthened up this sensation should go away.

Have you started physio yet???
Don't hesitate to contact your surgeon if you have any concerns.
