Knee instability and tibial osteotomy. A clinical study.

Twenty-one gonarthrosis patients were preoperatively assessed according to a newly developed orthoradiographic technique ("three-point measurement") and followed up for 2-3 years postoperatively using this technique. The medio-lateral instability of the knee joints was not influenced by the operation. The varus/valgus deviation was under-corrected, on average, but the deviation did not increase significantly with time after the operation. Judging from this pilot study the three-point measurement technique supplies relevant information and it is now being used in a prospective study on high tibial osteotomy in gonarthrosis.

Knee instability. An orthoradiographic study.

An orthoradiographic method for preoperative assessment of mediolateral instability and varus/valgus deviation in gonarthorsis is presented. A special definition of the varus/valgus deviation is given. The examination technique has been tested on 15 young, healthy subjects with no clinical signs or symptoms in their knee joints. To test the accuracy of the method, seven of the subjects were re-examined at a later date.

Mechanical properties of dried defatted spongy bone.

A study has been made of the compressive strength, compression at rupture, limit of proportionality, compression at the limit of proportionality and the modulus of elasticity of spongy bone from vertebrae and tibias. The specimens were obtained from autopsy subjects of both sexes aged 14 to 89 years. There was a qualitative deterioration of most of the strength parameters with age, and also differences between the sexes and between vertebrae and tibia. Spongy bone was found to have the unusual mechanical property that, despite rupture, its compressive strength often steadily increased; this was especially the case for vertebrae from young males.
