[Biologic Reconstruction of Full Sized Cartilage Defects of the Hip: A Guideline from the DGOU Group "Clinical Tissue Regeneration" and the Hip Committee of the AGA].

Conclusions The cartilage surface of the acetabulum, where FAI-related chondral lesions appear, is considerably smaller than the weight-bearing cartilage surface of the knee joint. However, as in the knee joint, MACT is the therapy of choice for full-thickness cartilage defects of more than 1.5 - 2 cm(2). Minimally invasive types of MACT (e.g. injectable chondrocyte implants) should be preferred in the hip joint. In cases where a single-stage procedure is indicated or there are other compelling reasons for not performing a MACT, a bone marrow-stimulating technique in combination with a biomaterial covering is preferable to standard MFx. For treatment of lesions smaller than 1.5 - 2 cm(2) the indication for a single-stage procedure is wider. As with defects in the knee, it is not possible to determine a definite upper age limit for joint-preserving surgery or MACT in the hip, as the chronological age of patients does not necessarily correlate with their biological age or the condition of their joints. Advanced osteoarthritis of the hip is a contraindication for any kind of hip-preserving surgery. Long-term observations and prospective randomised studies like those carried out for other joints are necessary. PMID: 28915523 [PubMed - as supplied by publisher]
