To date, there has not been a satisfactory screening test developed that can detect susceptible individuals. There has been some important scholarly research examining chondrolysis, and hopefully such a test can be developed in the future.

One interesting study is called, �Fibronectin-fragment-induced cartilage chondrolysis is associated with release of catabolic cytokines.� By G A Homandberg,how effective are diet pills, F Hui, C Wen,how effective are diet pills, C Purple, K Bewsey, H Koepp,how effective are diet pills, K Huch, and A Harris – Biochem J. 1997 February 1; 321(Pt 3): 751�757. Here is an excerpt: �Fibronectin fragments have both catabolic and anabolic activities toward articular cartilage explants in vitro. Whereas a 1 nM concentration of an N-terminal 29 kDa fibronectin fragment (Fn-f) increases the proteoglycan (PG) content of cartilage without induction of matrix metalloproteinases (MMPs), 0.1-1 microM Fn-f temporarily suppresses PG synthesis and enhances MMP release. The higher concentrations cause an initially rapid PG depletion during the first week of culture, followed by much slower PG loss and gradually increasing rates of PG synthesis.

To test for the involvement of mediators, human articular cartilage was cultured with Fn-f, and conditioned media were assayed for selected cytokines and factors. With 1 nM Fn-f, the release of the anabolic factors, insulin growth factor-I and transforming growth factor beta1, from cultured cartilage was enhanced by 50-100% during the entire 28-day culture period and this was associated with both supernormal rates of PG synthesis and PG content. However, the higher concentrations of Fn-f additionally enhanced release, by at least 10-fold, of the cytokines, tumour necrosis factor alpha, interleukin-1alpha, interleukin-1beta and interleukin-6 while causing depletion of cartilage PG. Release of tumour necrosis factor alpha,how effective are diet pills, interleukin 1beta and interleukin 1alpha peaked at days 2, 3 and 9 during or slightly after the period of maximal PG depletion and decreased to control levels by days 7, 7 and 21 respectively, whereas release of interleukin 6 was enhanced throughout the culture period. Neutralizing antibodies to the catabolic cytokines reduced Fn-f-mediated MMP-3 release and suppression of PG synthesis. The temporal aspects of this interplay between catabolic and anabolic factors are consistent with the kinetics of Fn-f-mediated cartilage damage and attempted repair and may be relevant to cartilage damage and repair in vivo.�

Another interesting article is called, �Chondrolysis and Avascular Necrosis: Complications of Slipped Capital Femoral Epiphysis� by Lubicky, John P. M.D. – Journal of Pediatric Orthopaedics B: 1996 – Volume 5 – Issue 3 Chondrolysis and Avascular Necrosis: Here is an excerpt: �Summary: Chondrolysis and avascular necrosis (AVN) are serious complications after slipped capital femoral epiphysis (SCFE). Chondrolysis, or acute cartilage necrosis of the capital femoral epiphysis, can occur in treated and untreated SCFE. Its exact etiology has not been conclusively determined, and there may be some connection with hardware penetration into the joint and its development. Because chondrolysis can occur in both treated and untreated hips, an immune mechanism has been postulated. Although some evidence of immune reaction has been confirmed in the joint, no screening test has yet been developed to determine susceptible individuals. AVN is clearly related to impeded blood supply to the femoral head and to severely slipped unstable acute slips. Forceful reduction of the femoral head must be avoided. However, some slips are so unstable that reductions occur merely with positioning of the patient for operation. Improperly placed fixation devices may also play a role in the development of AVN. Chondrolysis and AVN may not be completely avoidable in the treatment of SCFE.�
