This 1976 cadaveric biomechanical study tested 12 canine and 12 human knee joints under compression before and after sequential meniscectomy. It directly measured contact area, joint stress, and energy absorption to answer whether removing the meniscus actually changes the mechanical environment — and by how much. It is the foundational paper establishing the meniscus as an active load-bearing structure.
Total meniscectomy was standard of care in 1976 — the meniscus was widely considered a vestigial structure, and its removal was thought to be benign. Krause et al. Provided the first direct biomechanical proof that the meniscus bears 30–55% of the knee load in humans and that its removal triples joint stress.
When you see a bucket-handle tear in a young patient, this paper is why you repair rather than debride. When partial meniscectomy is unavoidable, the mechanical deficit scales directly with tissue removed. Take as little as possible.
The hoop stress mechanism also explains why radial tears are particularly dangerous: they sever the circumferential fibers that give the meniscus its load-bearing capacity, converting an intact ring into a mechanically incompetent structure even before any tissue is lost.
