When the patient wears a brace, strength training is allowed, but only in the 0° to 20° range immediately after surgery in order to limit compression of the affected chondral surfaces. This is because there are no long-term studies available similar to those that have been done to evaluate the procedure in the knee.

Imaging is also necessary for proper patient selection. When developing the microfracture procedure, Dr Steadman recognised that development of a post-operative protocol was needed to protect the repair and facilitate cartilage regrowth. Mancini D, Fontana A (2014) Five-year results of arthroscopictechniques for the treatment of acetabular chondral lesions infemoroacetabular impingement. ANSWER: Ankle replacement surgery is a complex procedure, and its typically used only after other treatments havent worked. A follow-up to this study showed no differences at 5 years 23). Most prior cartilage procedures had little to no emphasis on the post-operative period. Steadman referred to early basic science equine studies that paved the way for microfracture as it is performed today. 41 years experience Orthopedic Surgery. Experience shows that this hybrid repair tissue is durable and functions similarly to articular cartilage. Earlier bone remodelling was noted by changes in porosity 7). The long-term effectiveness of the technique in these other joints is unknown. Microfracture creates a rough surface on the subchondral bone. In 2015, Domb et al.

Even a partially successful procedure can greatly enhance function and delay or eliminate the need for more aggressive surgery … They conclude that at the short term clinical outcomes improve in both microfracture autologous matrix-induced chondrogenesis and autologous matrix-induced chondrogenesis groups. Frisbie DD, Trotter GW, Powers BE, Rodkey WG, Steadman JR, Howard RD et al. Twenty two percent of the patients remain unchanged and about three percent are made worse. Standard anteriorposterior and lateral images are also reviewed. Various complementary biological treatments have been suggested, but they will always be complementary to the microfractures 14). HSS physicians have used distraction arthroplasty for ankle arthritis for a decade and recently began using it for knees. A 90° awl is used for the patella if an angle cannot be created to accommodate the 45° awl. After assessing the cartilage damage, any unstable cartilage is removed from the exposed bone.

The success rate: Microfracture does not work for everyone. The rehabilitation program is designed to promote the ideal physical environment in which the bone marrow cells can transition into the appropriate cartilage-like cell lines. Find out why Microfracture fails & why other cartilage repair techniques drive better outcomes. All patients receive cold therapy after surgery to reduce inflammation as well as pain. Your physical therapist will teach you exercises during the rehabilitation program to regain muscle strength, promote healing and gain normal range of motion of the joint.

At 4 and 12 months following microfracture, there was more repair tissue in defects that were treated with microfracture compared to untreated lesions. Rarely a patient may become stiff and require a further procedure to restore motion. Several peer-reviewed basic science studies proved the concepts behind microfracture in the 1990s and 2000s 5). 32) published a new series of patients with a femoroacetabular impingement and chondral lesions treated by hip arthroscopy. Find out why Microfracture fails & why other cartilage repair techniques drive better outcomes. Several factors to take into consideration for use of the microfracture procedure include patient age, acceptable bio-mechanical alignment of the knee, activity level, the patient’s willingness to accept the extensive rehabilitation protocol and the individual’s expectations. When the microfracture is on the top of the shin bone (tibia) or the end of the thigh bone (femur), weight is limited by having a patient use crutches.

Starting 12 weeks after microfracture, the exercise programme is the same one used for femorotibial lesions. Options for complementary biological treatments include the use of growth factors (Plasma Rich Protein), collagen membranes, stem cells, chondrocyte grafts or, in case of open surgery, osteochondral grafts.
