Even though minor rifts in surgical gloves happen every now and then most surgeons don’t think too much about them. A study by Carter et al. indicate that we probably should be more worried: we miss to detect about 2/3 of the perforations. In 80 % of the cases we also failed to acknowledge that also the inner glove was perforated. Not surprisingly the surgeon had the highest rate of perforations, between 4-9 %, relating to procedure difficulty. Continue reading
It is rare to see long term follow-up studies ( > 5 years) and Bentley et al’s randomized controlled study on cartilage defects is therefore a rare bird! They randomized 1 00 consecutive patients to chondrocyte transplantation or mosaicplasty. After 10 years they were able to follow-up 94 % of all patients – a truly amazing accomplishment!
The method for chondrocyte transplantation was “simple”: harvest a few chondrocytes from the knee, grow them in a dish and the reinsert them and cover it up with a piece of tissue so that the cells don’t escape. I guess growing the cells requires a lot of expertise but apart from that no fancy gadgets were needed. Continue reading
Today’s blog is about gluing cartilage onto trauma-caused joint cartilage defects. Crawford et al report a new treatment option where they grow chondrocytes, attach them to a soft jelly (collagen matrix) and then glue it onto the defect! They randomized 21 to the NeoCart jelly and 9 patients to standard microfracturing and followed them for 2 years. Continue reading
