Effects of Unloader Bracing in Clinical Outcome and Cartilage Physiology Following Microfracture of Chondral Defects (Mfxbracing)
Effects of Unloader Bracing in Clinical Outcome and Articular Cartilage Physiology Following Microfracture of Isolated Chondral Defects
The study will examine clinical and radiographic outcomes of microfracture surgery (a common technique to address isolated areas of cartilage loss) in the knee used with or without unloader bracing. Randomly selected patients will wear an unloader brace, which is designed to take pressure off the area of the knee which underwent repair, for several weeks after surgery. Our hypothesis is that bracing may improve clinical and or radiographic outcomes.
The surgery performed will be the same for all patients
The length of follow up and schedule of post-operative MRI will be the same for all patients.
The only difference in groups will be presence of absence of brace wear.

详细说明
The study will examine clinical and radiographic outcomes of microfracture surgery (a common technique to address isolated areas of cartilage loss) in the knee used with or without unloader bracing. Radiographic outcome will be assessed via MRI scans post-operatively. Randomly selected patients will wear an unloader brace, which is designed to take pressure off the area of the knee which underwent repair, for several weeks after surgery. Our hypothesis is that bracing may improve clinical and or radiographic outcomes.
The surgery performed will be the same for all patients
The length of follow up and schedule of post-operative MRI will be the same for all patients.
The only difference in groups will be presence of absence of brace wear.

Knee Injury and Osteoarthritis Outcome Score (KOOS) (Clinical Outcome)
大体时间：2 years
|
KOOS is a validated outcome score that evaluates knee symptoms, knee pain, knee use in activities of daily living, function in sport and recreation and knee-related quality of life.
Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems as common in orthopaedic scales and generic measures.
Scores between 0 and 100 represent the percentage of total possible score achieved.

Change From Baseline in Tegner Score (Clinical Outcome)
大体时间：2 years
|
The Tegner activity level scale is a graduated list of activities of daily living, recreation, and competitive sports.
The patient is asked to select the level of participation that best describes their current level of activity and that before injury.
A score of 0 represents sick leave or disability pension because of knee problems, whereas a score of 10 corresponds to participation in national and international elite competitive sports.
A score >6 can only be achieved if the person participates in recreational or competitive sport.

Change From Baseline in SF-12 Quality of Life Score (Clinical Outcome)
大体时间：2 years
|
SF-12 scale is a generic, multipurpose short-form survey with 12 questions selected from the SF-36 Health Survey which, when combined, scored and weighted, results in two scales of mental and physical functioning and overall health-related quality of life.
A higher value indicates a better quality of life of the patient.
The scores range from 0 to 100.

Change From Baseline in Lysholm Score (Clinical Outcome)
大体时间：2 years
|
The Lysholm score is an indexed score of knee functional ability, with 0 being the worst score and 100 being the best score, indicating no limitations in activity/function.
