A 46-year-old member asked:

can the knee's acl and pcl ligament injuries heal naturally?

Acl/pcl healing: If an acl and PCL tear these ligaments do not typically heal; this is due in part to the synovial environment in which these ligaments reside as well as the demand that is exacted on these ligaments. Whether one is symptomatic with these injuries is in large part measured by the degree of activity in which a patient participates in and the number of hours one is actively engaged.
Dr. Rick Pospisil

Acl /pcl: Most of the supportive structures within the knee can not heal as they lack a good blood supply. Thus ,both Acl/ pcl , medial ,lateral meniscus, and the articular surfaces don't / can't heal on their own
Dr. Bernard Bach Jr

Generally not.: If theyre completely torn, they generally cannot heal , and need surgical reconstruction

A 44-year-old member asked:

Does knee dislocation have any long-term consequences?

1 doctor answer1 doctor weighed in
Dr. Frederick Buechel, jr. md
Orthopedic Surgery 26 years experience
Yes : Potentially post traumatic arthritis can occur. If you have just a knee cap dislocation, it may predispose you to future dislocations and anterior knee pain and arthritis. If it is your whole knee joint that dislocates, you risk nerve, vessel and ligament injury. This is a much more severe injury than just a patella dislocation.
A 45-year-old member asked:

Is a microfracture procedure advisable for a meniscus tear in the knee?

1 doctor answer4 doctors weighed in
Dr. Frederick Buechel, jr. md
Orthopedic Surgery 26 years experience
NO: Microfracture is done when the end of the bone cartilage surface has an area that is worn off. You then use a small "pick" to puncture the bone in the area that the cartilage is worn off to try to make the bone bleed onto this surface and create some scar cartilage to form in the cartilage defect area. The repair cartilage is not normal cartilage but can help some patients. Not for meniscus tear.

See below: Don't use just your back. Bend at the knee and hips, when you are helping the person stand. That will allow you to take the strain off of your back.

What would you need to do to prepare for total knee replacement?

2 doctor answers5 doctors weighed in
Dr. Frederick Buechel, jr. md
Orthopedic Surgery 26 years experience
Many options: To prepare for a total knee replacement first you should have an informed discussion with your surgeon. Then maximize your health for surgery. Improve your eating habits and take appropriated nutritionals. Do your best to pre-surgically exercise your thigh muscles and hamstrings in preparation for your postop rehab. Get your ice machine ready at home, your walker and a cane. These are basics.

You will also need a preoperative medical evaluation to make sure you are safe for anesthesia. I also have all my patients get a dental check up to ensure there is no active gum or tooth infections that can infect your new knee replacment. If you are overweight, try your best to address your diet and activity to loss some weight and keep on that routine after surgery. Avoid gardening or activities that can scratch your skin prior to your surgery because your surgeon will cancel your surgery if you have open cuts or scrapes on your operative leg the day of surgery. Contact your insurance company to find out what therapy centers in your area accept your insurance for after surgery and which rehab facilities you can go to after surgery if you do not go right home from the hospital.

My son is 6 and has been healthy. He started having seizures. He is under medication. Why can this be happening? No head injury or illness.

Seizure disorder: The brain goes through a rather lengthy period of development& growth& continues to remodel itself until the late 20's. A seizure disorder, whether transient & benigh or long term, can emerge at any age & for a variety of reasons. Your dr or neurologist may have a clue for origin after tests, but a large percentage arise from no known reason & are labeled "ideopathic".
