How long does it take to recover from microfracture surgery?
Depending upon the location of the microfracture and the size of the defect, it can take anywhere from 4 to 7 months to be able to heal to the point where patients can increase their activities and potentially initiate occasional impact activities.
What is a trabecular microfracture?
Bone bruises (also known as bone contusion, trabecular microfracture) are an osseous injury that results from compression of bone structures.
What is the success rate of microfracture knee surgery?
The success rate: Microfracture does not work for everyone. In degenerative knees it has been found to have about a 75% success rate. Twenty two percent of the patients remain unchanged and about three percent are made worse.
Is microfracture major surgery?
Microfracture surgery is an articular cartilage repair surgical technique that works by creating tiny fractures in the underlying bone. This causes new cartilage to develop from a so-called super-clot….
How painful is microfracture surgery?
You will not feel any pain during the surgery. Three types of anesthesia may be used for knee arthroscopy surgery: Local anesthesia — You will be given shots of painkillers to numb the knee. You may also be given medicines that relax you.
When can I walk after knee microfracture?
Patients will be advised to use crutches for 4 – 6 weeks when the injury is located at the top of their tibia or is sustained at the end of the femur. If the microfracture injury is on the patella (kneecap), then all motion must be limited with no bending of the knee for as long as Dr.
What causes trabecular microfracture?
The bone loss in the vertebral bodies is by a loss of horizontal trabeculae. This loss reduces the resistance of vertical elements to deformation under load and creates the conditions for trabecular fracture.
What does trabecular mean?
Definition of trabecula 1 : a small bar, rod, bundle of fibers, or septal membrane in the framework of a body organ or part.
What happens when microfracture fails?
When the healing is inadequate, pain recurs. Over time, in the absence of healing, the initial damage to the articular cartilage gets worse. This leads to post-traumatic arthritis, a loss of cartilage, and the deformation of the underlying bone.
Does microfracture knee surgery work?
Does microfracture work well? Yes, in properly selected and compliant patients. Microfracture can be an excellent procedure, providing substantial pain relief when done in the right patient. One of the concerns with microfracture is that it does not stimulate the growth of normal joint cartilage.
How long does it take to walk after microfracture?
You will need to keep your weight off your knee for 6 to 8 weeks unless told otherwise. You will need crutches to get around. Keeping the weight off the knee helps the new cartilage grow. Make sure you check with your doctor to find out how much weight you can put on your leg and for how long.
How long are you on crutches after microfracture surgery?

As soon as possible after surgery, you should begin passive motion exercises either with a physical therapist or using a CPM machine while in bed.
What is microfracture surgery for the knee?
Knee microfracture surgery is a common procedure used to repair damaged knee cartilage. Cartilage helps cushion and cover the area where bones meet in the joints. You will not feel any pain during the surgery. Three types of anesthesia may be used for knee arthroscopy surgery:
How many microfractures can be created in a total knee replacement?
The number of microfractures created depends on the size of the joint being treated. Most patients with a 1- to 2-centimeter area of damage require five to 15 small microfracture holes in the bone. The penetration of the outer layers of bone allows blood and stem cells to form a clot in the area of the cartilage defect.
What are the risks of microfracture knee surgery?
Microfracture surgery of the knee joint is a safe procedure with minimal risks. In fact, the primary risk is having persistent pain despite this attempt to heal the area of cartilage damage. Other risks of arthroscopic surgery include infection, blood clot, stiffness, and swelling of the knee joint.
Are You a good candidate for microfracture of the knee?
Patients who are good candidates for microfracture could also be good candidates for other treatments for cartilage defects of the knee. These alternatives include cartilage transfer and cartilage implantation.
