"Knee microfracture"

John B Schrock, Matthew J Kraeutler, Darby A Houck, Matthew B McQueen, Eric C McCarty
BACKGROUND: Numerous surgical options exist to treat chondral lesions in the knee, including microfracture (MFx), osteochondral autograft transplantation (OAT), first-generation autologous chondrocyte implantation (ACI-1), and next-generation ACI (ACI-2). PURPOSE: To compare the cost-effectiveness of MFx, OAT, and ACI-1. The secondary purpose of this study was to compare the functional outcomes of MFx, OAT, ACI-1, and ACI-2. STUDY DESIGN: Systematic review; Level of evidence, 2...

BACKGROUND: Microfracture (MFx) and autologous chondrocyte implantation (ACI) are 2 surgical treatment options used to treat articular cartilage injuries of the knee joint. PURPOSE: To compare the midterm to long-term clinical outcomes of MFx versus ACI for focal chondral defects of the knee. STUDY DESIGN: Systematic review. METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to locate studies (level of evidence I-III) comparing the minimum average 5-year clinical outcomes of patients undergoing MFx versus ACI...

Microfracture is a marrow-stimulating technique used in the hip to treat cartilage defects associated with femoro-acetabular impingement, instability, or traumatic hip injury. These defects have a low probability of healing spontaneously and therefore often require surgical intervention. Originally adapted from the knee, microfracture is part of a spectrum of cartilage repair options that include palliative procedures such as debridement and lavage, reparative procedures such as marrow-stimulating techniques (abrasion arthroplasty and microfracture), and restorative procedures such as autologous chondrocyte implantation and osteochondral allograft/autografts...

The purpose of this study was to evaluate long-term outcome, following microfracture of the knee in a large patient group, using a random-effect model for longitudinal data analysis. There were 350 subjects (males, 55%; females, 65%) who underwent knee microfracture by a single surgeon between 1992 and 2002. Mean age was 48 years (range, 12-76 years). Subjective questionnaires were collected from patients at 1 year postsurgery and each consecutive year thereafter. Of treated chondral lesions, 53% were traumatic lesions, and 47% were degenerative...

Chondral injuries of the hip joint are often symptomatic and affect patient activity level. Several procedures are available for addressing chondral injuries, including microfracture. Microfracture is a marrow-stimulating procedure, which creates subchondral perforation in the bone, allowing pluripotent mesenchymal stem cells to migrate from the marrow into the chondral defect and form fibrocartilaginous tissue. In the knee, microfracture has been shown to relieve pain symptoms. In the hip, microfracture has been studied to a lesser extent, but published studies have shown promising clinical outcomes...

Articular cartilage defects of the knee have been shown to cause pain, swelling, decreased function, and suboptimal athletic performance. Treatment of elite-level athletes presenting with full-thickness chondral defects of the knee continues to be a challenge for orthopedic surgeons. The purpose of this study was to document outcomes in elite professional alpine ski racers after microfracture surgery. This study was approved by an institutional review board. All patients who competed in professional ski races recognized by International Ski Federation and had a full-thickness knee articular cartilage defect, treated with microfracture, by a single surgeon, were included in the study...

PURPOSE: The aim of this study was to determine the effect of compartment location, concomitant arthroscopic surgery and smoking on the medium-term outcome of knee microfracture. METHODS: From a database of all 396 patients treated with microfracture for cartilage lesions in our Unit, details were taken of the 316 patients who met our inclusion criteria. Outcome was assessed by a self-administered postal questionnaire containing a general satisfaction question and a battery of four functional assessment scores...

OBJECTIVE: Our aim was to determine whether response shift (RS), a change in the internal standards of a patient, occurs in patients treated for full thickness knee cartilage defects. We have also evaluated the effect of functional scores on patient satisfaction after surgery. DESIGN: Self-administered questionnaires were used to evaluate pre- and post-operative and retrospective post-operative scores of 53 patients following knee microfracture. Patient satisfaction, Lysholm, Visual Analogue Scale (VAS) for pain and modified International Knee Documentation Committee (IKDC) scores were evaluated...

Most studies addressing treatment of chondral injuries have involved the knee. Various techniques have been used in the knee. Microfracture has shown excellent results in the knee. Chondral injuries of the hip are common in athletes with labral tears and femoroacetabular impingement. The microfracture technique is now being used in the hip joint. Indications include full-thickness cartilage loss or unstable flap on a weight-bearing surface. An important contraindication is the patients unwillingness to follow the postoperative protocol and rehabilitation plan...

Although many methods currently are available to treat articular cartilage lesions in the knee, microfracture has many inherent advantages. No other technique has been studied in the athletic population, and, in fact, most other procedures have been studied in the arthritic knee or in a mixed population of patients. Blevins et al have shown microfracture to be an effective tool in the treatment of chondral defects in both recreational and high-level athletes with mean follow-up of 3.7 years. Furthermore, microfracture is minimally invasive because it is arthroscopic through standard portals in most cases...
