I’m not a fan of joints. They are clunky and prone to injuries and pain. I know they are an evolutionary marvel and all, letting us have load-bearing appendages that provide mobility and agility. However, I note that a penis is a load-bearing appendage and it does just fine without bones and joints.
Given we have to have them, it is good to know there are clever humans around who can build near indestructible replacements for when we wear our feeble natural ones out.
I’d like to think that one day full limb replacement can occur. Yes, hands and feet pose a significant challenge, but certainly the long bones may be able to be exchanged for titanium or carbon fibre. As for bone marrow and blood cell manufacture, I’m happy to keep the fantasy simple for the time being.
The other items I’m sure you’ve noticed in this picture are the little white beads that have been placed around the joint. These antibiotic beads are the equivalent of Osmocote, except that they are impregnated with therapeutic drugs to provide prolonged release of high doses directly into the vulnerable region. They all but eliminate the risk of toxicity and other complications such as blood vessel damage which often occurs with intravenously administered antibiotics.
First developed in the 1970s, beads would be made up in the operating theatre using mix and set medical cement and a raft of antibiotics to match the treatment required.
In more recent years, as are pictured, prefabricated antibiotic beads are now being phased in which dissolve over time to provide the same targeted and sustained release of drugs without the need for follow up surgery to remove them.
So you can have your Steve Austin knees with much less chance of them turning septic.
Now all they need to replace is meat.
