ABSTRACT

Because articular chondrocytes have a long-term exposure to different degrees of hypoxic environment , hypoxia induc-ible factor is considered to be one of the most important regulation factors to adapt to low oxygen levels .It plays a significant role in the metabolism, repair, and degeneration of cartilage chondrocyts .This article reviews the comprehensive effects of hypoxia inducible fac-tor in cartilage chondrocyts .

ABSTRACT

Objective Uncemented prothesis has become the preference of first hip arthroplasty, but there is a little study on its application in cemented acetabular revision arthroplasty.This paper aimed to evaluate the clinical effects of uncemented acetabular cup in cemented acetabular prosthesis revision arthroplasty. Methods A retrospective analysis was made on the clinical data of 31 patients(31 hips) who underwent revision arthroplasty using uncemented acetabular prosthesis from January 2012 to March 2015.Har-ris hip score( HSS) was applied to measure the hip function and visual analogue score( VAS) was preformed to assess the pain degree of knee joint preoperatively and postoperatively(3 months, 6 months and 1 year).All the patients were followed up for a mean of 22 months ranging from 3 to 42 months. Result The mean HSS increased from preoperative points (53.19 ±9.12) to postoperative points([77.71 ±5.75]at 3 months,[80.61 ±5.74] at 6 months,[82.94 ±5.80] at 1 year ).The mean VAS score decreased from preoperativepoints (6.23 ±1.23) to postoperative points(0.26 ±0.27).No lossening, infection or deep vein thrombosis were found in the patients′prostheses. Conclusion For patients with PaproskyI-Ⅱ acetabular defects, uncemented acetabular prosthesis has satisfactory short-term clinical results in revision arthroplasty with cemented acetabular prosthesis, however, long-term clinical results remain to be further observed.
