“…It is known that the diameter of the lesions measured on MRI can exceed that shown on conventional radiographs. 34 This is important for the pre-operative planning of drilling, because sufficient perforation of the sclerotic bone is essential.…”

“…An advantage of diagnostic arthroscopy over radiological methods is that not only inspection of the cartilage is possible, but by palpation with a probe it is possible to determine if there are soft spots or delaminated areas to pinpoint an OLT. 34 Furthermore, once the OLT has been detected it can be treated during the same procedure. In our study all OLTs were identified by arthroscopy, but four of eight tibial lesions were missed.…”

Our aim in this prospective study was to determine the best diagnostic method for discriminating between patients with and without osteochondral lesions of the talus, with special relevance to the value of MRI compared with the new technique of multidetector helical CT. We compared the diagnostic value of history, physical examination and standard radiography, a 4 cm heel-rise view, helical CT, MRI, and diagnostic arthroscopy for simultaneous detection or exclusion of osteochondral lesions of the talus. A consecutive series of 103 patients (104 ankles) with chronic ankle pain was included in this study. Of these, 29 with 35 osteochondral lesions were identified. Twenty-seven lesions were located in the talus.Our findings showed that helical CT, MRI and diagnostic arthroscopy were significantly better than history, physical examination and standard radiography for detecting or excluding an osteochondral lesion. Also, MRI and diagnostic arthroscopy performed better than a mortise view with a 4 cm heel-rise. We did not find a statistically significant difference between helical CT and MRI. Diagnostic arthroscopy did not perform better than helical CT and MRI for detecting or excluding an osteochondral lesion.

“…Because cartilage tissue cannot be directly delineated in radiography, X-ray changes are observed only in the later and more severe stages of disease and display a relatively low specificity and sensitivity. A series of studies have qualitatively evaluated ankle joint cartilage in normal volunteers and patients [7,25,26,36,46], but only few investigators have attempted to quantitatively assess the cartilages of the human hind foot from MR images [42,44]. *Corresponding author.…”

Alterations of ankle cartilage are observed in degenerative and inflammatory joint disease, but cartilage cannot be directly visualized by radiography. The purpose of this study was therefore to analyze the feasibility and precision of quantitative cartilage imaging in the human hind foot (talocrural, talotarsal, and intertarsal joints), and to report the inter-subject variability for cartilage volume, thickness and surface areas. The feet of 16 healthy volunteers were imaged using a 3D gradient-echo magnetic resonance imaging sequence with water-excitation. After interpolation to a resolution of 1 z 0.125 y 0.125 mm? the cartilage plates were segmented, and the cartilage volume, thickness, and surface areas determined. The precision (four repeated measurements) was examined in eight volunteers, the RMS average CV% being 2.1% to 10.9% in single joint surfaces, and < 3% for the cumulative values of all joints. The mean cartilage thickness ranged from 0.57 i 0.08 (navicular surface) to 0.89 5 0 . 1 9 mm (trochlear surface for tibia). In conclusion this study shows that it is feasibIe to quantify thin cartilage layers in the hind foot under in vivo imaging conditions, and that the precision errors are substantially smaller than the inter-subject variability in healthy subjects.

“…Over the past several decades in clinical orthopaedic work, techniques to treat chondral defects included abrasion, drilling, micro-fracturing of the underlying bone, tissue autografts, allografts, and cell transplantation [1,3,15,16,21,26,27,28,34,40,41,51]. In recent years more has been learned about various growth factors that stimulate chondrocyte differentiation and cartilage matrix production, but to date no procedure has been fully successful in achieving properly structured regenerative articular cartilage.…”
