30) published a series of 20 patients who underwent microfractures in acetabular chondral defects. Outcomes following microfracture of full-thickness articular cartilage lesions of the knee in adolescent patients. This surface allows the marrow clot to adhere more easily, while the integrity of the subchondral plate is maintained for joint surface shape. At roughly 8 weeks the patient progresses to full weightbearing. It is essential to limit compression of the new surfaces in the early postoperative period, so that the maturing marrow clot will not be disturbed. “We’ve been able to show in several studies that if you follow both the operation and the rehabilitation program, the chances of success are pretty high.”. The original description and regimen for microfracture was a combination of surgery and rehabilitation which would allow cartilage repair tissue to form in the articular cartilage defect. In a group of professional skiers who underwent microfracture, excellent patient-centered outcomes were seen at an average of 77 months follow-up13. In addition, type II collagen was increased, with 74% type II collagen at 12 months. Steadman and colleagues at the Steadman Hawkins Clinic have conducted numerous studies on microfracture, showing long-term success up to 11 years and success in high-level athletes, as shown in a 2003 study on National Football League players. The use of crutches, with only light touch-down weight allowed on the involved leg, is prescribed for 6 to 8 weeks. Philadelphia: Lippincott Williams & Wilkins 2007. Brace use is rarely recommended for patients with chondral defects on the femur or tibia. Based on second-look arthroscopies, the study concluded that patients who used CPM (continuous passive motion) had improved cartilage healing. Patients will often report a deep ankle pain. The doctor must examine the knee before the patient is released to full activity. These picks also allow surgeons to create the rough surface to which the marrow clot adheres. A cartilage stimulating procedure (microfracture) has been performed to encourage the body to cover the exposed bone with scar tissue. He typically uses three different angles of picks in order to reach every possible point in the joint. Figure 2. Microfracture surgery is quick (typically lasting between 30–90 minutes), minimally invasive, and can have a significantly shorter recovery time than an arthroplasty (knee replacement). (Left) Damaged cartilage is removed. An average filling of the chondral defect of 93% (±17%) was found, defining the cartilage as macroscopically stable. In: The crucial principles in care of the knee. today and the surgeon said “if this does not work” and went on to describe what would be done next. In the case of a suspected chondral defect, a magnetic resonance image (MRI) allows for confirmation of the articular cartilage defect and allows for analysis of co-pathologies. HipInt 24(5), 448–456. 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. Domb BG, El Bitar YF, Lindner D, Jackson TJ, Stake CE(2014) Arthroscopic hip surgery with a microfracture proce-dure of the hip: clinical outcomes with two-year follow-up. Patients are placed into a continuous passive motion (CPM) machine immediately following surgery. One study has shown a success rate of 75 to 80 percent among patients 45 years of age or younger. Images with both knees flexed to 30 or 45 degrees in a weightbearing position are also included. The microfracture technique. Although all patients showed a significant improvement in all measured scores, there was no significant difference in the two studied groups 33). The study showed that microfracture, with the recommended post-operative protocol, is an acceptable treatment option for elite skiers who have full thickness articular cartilage lesions of the knee. The patient may report associated periods of locking or catching of the ankle joint. (2017). Limited strength training also begins immediately after microfracture surgery. Brace use is generally discontinued at about 12 weeks. Received a 3-series shot of synvisc. In addition, it is extremely important to manage the patient’s expectations. Limited strength training also begins immediately after microfracture surgery. Success rate for microfracture surgery for OCD of talus I am scheduled to have this procedure done on 8/21/12. Full activity may be resumed once the physician has examined the knee and given approval for the patient to return to sports activity. Imaging is also necessary for proper patient selection. This allows a small telescope and instruments to be placed inside the ankle. Microfracture—the puncturing of holes to release marrow blood in joint surfaces with cartilage injuries—is reported to be failing in most cases after a few years. Ankle replacement fact #1: Success rates are promising. The results showed a decrease in symptoms and improved function. The newly formed cartilage is not as strong as the body’s original cartilage, and thus, there is a risk of it breaking overtime. to 85 postoperative) in the Modified Harris Hip Score. However, the autologous matrix-induced chondrogenesis group had better and more durable improvement. Twenty two percent of the patients remain unchanged and about three percent are made worse. Arthroscopy 28, 322–329. Improvement of full-thickness chondral defect healing in the human knee after debridement and microfracture using continuous passive motion. Can microfracture be used in joints other than the knee? Search. A recent study concluded that if the patient is over 25 years old or the ankle lesion is greater than 1.5 cm sq., microfracture surgery is more likely to have problems. However, no clinical results of these series were published. Forty patients were treated in each group. This is an imperative step and must be followed. Microfracture is widely used to treat hip and knee injuries. These areas are avoided during strength training for approximately 4 months. Bone marrow cells and blood from the holes combine to form a “super clot” that completely covers the damaged area. Am J Sports Med 2008; 36:1763-1769. Cold therapy is usually implemented for 1 to 7 days after surgery. Improvement in knee function may not occur for at least 6 months after microfracture, so patients are counselled preoperatively so they understand what to expect after surgery. Skip to main content 415-563-3110. J Vet Surg 1999; 28:242-255. The goal of microfracture is to stimulate the growth of new articular cartilage by creating a new blood supply. El Bitar Y, Lindner D, Jackson T, Domb B (2014) Joint-preserving surgical options for management of chondralinjuries of the hip. Patients with small defect areas (less than 1cm in diameter) may be allowed to put weight on the leg a few weeks sooner. Frisbie DD, Oxford JT, Southwood L, Trotter GW, Rodkey WG, Steadman JR et al. Microfracture success depends not only on the operation but rehabilitation as well Surgeon shares pearls for optimal results with using microfracture to repair articular cartilage. Assessing alignment, the line between the hip and knee crosses through the knee joint. Between 1 and 2 weeks after surgery the patient will be placed on a stationary bike without resistance and begin a deep-water exercise programme that involves running. Experience shows that this hybrid repair tissue is durable and functions similarly to articular cartilage. Crutch-assisted touch-down weight-bearing ambulation is prescribed for up 8 weeks based on the size of the lesion. Surgeons typically perform an abrasion arthroplasty along with microfracture in DJD cases, he noted. The study identified age as the only independent predictor of Lysholm improvement. In one study, he and his colleagues found that leaving the calcified cartilage layer interferes with new cartilage formation and significantly decreases the chances of growing new cartilage. The damaged and loose articular cartilage (and bone) on the end of the bone has been removed. A randomized trial. Outcomes of microfracture for traumatic chondral defects of the knee: average 11-year follow-up. This new blood supply from within the bone marrow, supplies the damaged joint surface with new stem cells to form fibrocartilage, which fills the damaged area and promotes the formation of new tissue. Steadman JR. The amount of weight put on the area of microfracture must be limited.2 This allows the cells to grow in develop in the area that underwent the microfracture treatment. McDonald JE, Herzog MM, Philippon MJ (2013) Return toplay after hip arthroscopy with microfracture in elite athletes.Arthroscopy 29(2), 330–335. Presented at the American Orthopaedic Society for Sports Medicine Specialty Day Meeting. Marquez-Lara A, Mannava S, Howse E, Stone A, Stubbs A(2016) Arthroscopic management of hip chondral defects: Asystematic review of the literature. He describes filling an average of 91% with a tissue described as stable 28). These young patients returned to full activity with no disability from their knee injury. This is because there are no long-term studies available similar to those that have been done to evaluate the procedure in the knee. what is the success rate for knee microfracture surgery? One study has shown a success rate of 75 to 80 percent among patients 45 years of age or younger 18). Philippon MJ, Schenker ML, Briggs KK, Maxwell RB (2008)Can microfracture produce repair tissue in acetabular chondraldefects? Even a partially successful procedure can greatly enhance function and delay or eliminate the need for more aggressive surgery such as total joint replacement or cartilage transplantation. When the brace is discontinued, patients are allowed to advance their training progressively. One patient did not return to skiing. Rarely is a second arthroscopy required for recurring effusions. Fortunately, there are alternatives. In the ankle, post-op (couldn’t walk at all for 3 1/2 months) had much more stability than prior to surgery, but extreme increased pain. The awl should be perpendicular to the bone as it is advanced. Hurst JM, Steadman JR, O’Brien L, Rodkey WG, Briggs KK. Outcomes of microfracture for traumatic chondral defects of the knee: Average 11-year follow-up”, Steadman et al., Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 19, No 5 (May–June), 2003: pp 477–484. Of these treatment strategies, the most common and most useful is microfracture – an arthroscopic procedure and rehabilitation programme that was developed in the early 1980s by Dr J. Richard Steadman 1). Previous work had been done with drills, but drills could not reach all areas of the joint and produced heat when used, which could limit the development of new tissue. Standing one-third knee bends with a great deal of the weight on the uninjured leg begin the day after surgery. The next basic science study proved that the removal of the calcified cartilage layer improved the grade of the repair tissue and the filling of the lesion 8). By way of background, I was a long jumper/triple jumper on the track team in college and banged up my right ankle pretty badly a couple times, though nothing that resulted in long term pain. Microfracture knee surgery success rate detoriates over time. When the microfracture is o… These angles are avoided during strength training for approximately 4 months. Surgeons remove any bone spurs – growths common in ankle arthritis – and drill small holes in the bone (called microfracture) to help stimulate cartilage repair. These holes penetrate into the subchondral bone and open up new blood supply to the area. Experts discuss what to expect after ankle surgery ... those reported for other three components with a survival rate at last review of 95% to 98%. Technically, microfracture surgery is a bone marrow stimulation procedure and is based on the puncturing of the subchondral bone plate into the bone marrow, the generation of a blood clot containing precursor cell populations derived from the subchondral bone marrow, and the spontaneous transformation of the repair clot into a fibrocartilaginous repair tissue. Full recovery from ankle replacement surgery can take up to a year. Then, a period of dynamic biking with increasing resistance. After 8 weeks, the brace is gradually opened and then discontinued. Knee microfracture is about a 20 year old orthopedic surgery technique that’s commonly used during knee arthroscopy to treat small holes in the cartilage. In the ankle, microfracture surgery works about 85% of the time, but the success rate varies with age. }); Is microfracture a “cure” for osteoarthritis? If a continuous passive motion (CPM) machine is not used, the patient begins passive flexion/extension (straightening and bending) of the knee with 500 repetitions three times a day. Microfracture also called microfracture surgery, is a articular cartilage repair surgical technique performed to promote the healing of damaged cartilage with the use of stem cells (progenitor cells of the body) that works by creating tiny fractures in the underlying bone. J Bone Joint Surg Am 2007; 89:2105-2112. Starting 12 weeks after microfracture, the exercise programme is the same one used for femorotibial lesions. In 2015, Domb et al. Knutsen G, Engebretsen L, Ludvigsen TC, Drogset JO, Grøntvedt T, Solheim E. Autologous chondrocyte implantation compared with microfracture in the knee. Improvement has been shown to occur slowly and steadily for at least 2 years, which has been supported by a clinical research data 17). One of the first publications about short-term clinical results in patients treated with microfractures for grade 4 chondral lesions of the hip was by Philippon et al. Even a partially successful procedure can greatly enhance function and delay or eliminate the need for more aggressive surgery … A randomised trial comparing autologous chondrocyte implantation with microfracture. “The thing you have to remember about this procedure is it’s a natural process,” Steadman said. This range of motion limits compression of the regenerating surfaces of the trochlea or patella or both. Rarely a patient may become stiff and require a further procedure to restore motion. This allows a small telescope and instruments to be placed inside the ankle. At Ortho Sport & Spine Physicians, patients can take advantage of a full menu of cartilage repair solutions. This study supported the use of CPM for 8 weeks following microfracture, in addition to non-weightbearing 12). Frisbie DD, Trotter GW, Powers BE, Rodkey WG, Steadman JR, Howard RD et al. Rodrigo JJ, Steadman JR, Silliman JF, Fulstone HA. I never had a situation where I could not get a perpendicular hole in the joint, whether posterolateral or posteromedial.”. 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. These scans are performed from the knee down and are used to measure angles in all dimensions. For this, patients will place about 10% to 30% of their body weight on the injured leg. Some patients may develop mild transient pain, most frequently after microfracture has been performed on the patella (kneecap) and trochlear groove (the groove on the femur in which the patella glides during motion). To further understand the composition of the repair tissue, Frisbie et al 9) looked at key matrix component expression in early cartilage healing following microfracture. For those lesions that cause symptoms in patients, several lines of treatment have been developed. (adsbygoogle = window.adsbygoogle || []).push({}); (adsbygoogle = window.adsbygoogle || []).push({ In 2016, Marquez-Lara et al. Recovery. Most prior cartilage procedures had little to no emphasis on the post-operative period. Some patients may even notice these symptoms while using the continuous passive motion machine (CPM), a device that gently moves the joint while the patient is lying down. Rehabilitation following microfracture for chondral injury in the knee. 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. A follow-up to this study showed no differences at 5 years 23). 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. A major advance in ankle replacement has been the use of pre-operative CT scans with the Wright Medical PROPHECY Guide.Through computer imaging and the patient’s CT scan, a patient-specific surgery plan is developed. Knutsen G, Engebretsen L, Ludvigsen TC, Drogset JO, Grøntvedt T, Solheim E. Autologous chondrocyte implantation compared with microfracture in the knee. After 8 weeks, the knee brace is gradually opened to allow increased flexion of the knee, a process that takes about a month. The best candidates are young patients with single lesions and healthy subchondral bone. Since this maturing process is gradual, it usually takes two to six months after the procedure for the patient to experience improvement in the pain and function of the knee. They conclude that at the short term clinical outcomes improve in both microfracture autologous matrix-induced chondrogenesis and autologous matrix-induced chondrogenesis groups. ClinOrthop Relat Res 467(3), 739–746. Surgeons may use the microfracture technique to treat traumatic lesions, which have surrounding cartilage rims, or degenerative joint disease (DJD) lesions.
