Exercise bike, eliptical, swimming (flutter kick, not frog kick) or any other non-impact activity should be ok as long as it doesn't cause symptoms. If it reproduces your symptoms, then you have to eliminate it.
Anterior medial would indeed make me more suspicious of either a meniscus tear or an injury to the fat pad, but would not necessarily eliminate the others.
Thank you so much Dr., Have a Merry Christmas.
thank you Dr., my final question is can I get on an excercise bike or swim while waiting for my symptoms to disappear? or should I totally rest my knee? If so, how long till I can ride an exercise bike.? I am sorry I am quite anxious since I love to be active.
Thank you again so much.
God Bless.
Thank you so much Dr. Your answers have really enlightened me. I just want to add that I made a typographical error in my earlier post, I meant to say anterior-"medial" not anterior-"middle" (where I hear pops and feel sensations of giving way). Does this mean anything to you? Furthermore, is there a chance that i sustained a meniscus or ligament tear?
Thank you so much again.
Hyperextension knee injuries can be trcky. Damage can include injury to the patella-femoral joint, sprain of the cruciate ligaments, or a bone bruise of either the tibia or femur. Essentially it can be just about anything.
From your history, I get a sense that this is an injury to the patella-femoral joint, either the cartilage on the back of the kneecap, or perhaps to the patella tendon.
Since the symptoms seem to get better with rest, I recommend resting for several weeks, not just eliminating running, but basketball as well. If the symptoms abate, then I would begin a course of quadriceps strengthening as you start a gradual return to sport. If the piain persists, returns, or worsens, you should see a physician for a thorough evaluation.
