“…However, generally, Sasazaki et al [54] studied bovine knee cartilage failure and reported that rupture of the sheath-like surface (or coating) of collagen fibrils occurred at 20% tensile strain and complete rupture occurred by 25% tensile strain. A recent validation study on human cartilage samples in the hip reported strains at physiological levels of loading up to 17.5% compressive strain, which likely falls in a tolerable range of strain [57]. Contact pressure has been studied in the hip in both computational and experimental studies.…”

Background Individuals with cam morphology are prone to chondrolabral injuries that may progress to osteoarthritis. The mechanical factors responsible for the initiation and progression of chondrolabral injuries in these individuals are not well understood. Additionally, although labral repair is commonly performed during surgical correction of cam morphology, the isolated mechanical effect of labral repair on the labrum and surrounding cartilage is unknown.The institution of one or more of the authors (JNT, JAW) has received, during the study period, funding from the National Science Foundation, and the LS Peery Foundation. The institution of one or more of the authors (AEA) has received, during the study period, funding from National Institutes of Health. One of the authors (TGM) certifies receipt of personal payments or benefits, during the study period, in an amount USD 10,000 to USD 100,000 from Arthrex. One of the authors (GAA) certifies receipt of personal payments or benefits, during the study period, in an amount less than USD 10,000 from Allosource.

Acetabular fractures are known for their disabling outcomes, so the search for optimal treatment tactics is an actual problem for modern orthopedics and traumatology. Materials and methods. Randomized trials that reflect the results of acetabular fractures treatment depending on the method of treatment were analyzed. The literature was searched in the PubMed Central database. Hip joint is a complex two-component articulated system. Traumatic lesion of all elements of the joint creates the conditions for the development of a wide range of complications and secondary changes that must be taken into account at preoperative treatment. Acetabular fracture is an intra-articular injury, where the visualization methods have the prominent significance. Nowadays the treatment can be conservative and surgical. Surgical treatment can be divided into two areas: osteosynthesis and arthroplasty. Anatomical reposition and stable fixation of fragments, in the most of cases, is the key to a satisfactory functional result, but the development of post-traumatic changes in the joint nullifies the results of even perfect osteosynthesis, encourages repeated surgery and, finally, hip replacement. In recent years, primary arthroplasty has been successfully used to treat acetabular fractures, reducing inpatient and rehabilitation period, compared with osteosynthesis, preventing the possible development of secondary degenerative changes in the joint. Conclusions. Acute hip replacement is an effective treatment, however, the technical aspects of reliable fixation of the acetabular component of the implant are insufficiently substantiated and highlighted in actual literature and constitute significant research interest.
