“…A linear spring connected the modeled beak to the braincase, and its compression allowed the deceleration of the braincase to be attenuated (Figure 3A). As a measure for hammering performance, penetration into wood was calculated following the theoretical physics of driving a nail into wood 24 (Figure S3).…”

“…This formulation corresponds to a simple mathematical model of a straight-tapered tip of a nail penetrating wood. 24 The stiffness constant K wood describes the slope of this linear increase in wood-counterforce with penetration depth. This constant was fine-tuned to achieve a realistic peak deceleration of 1.7 10 3 m s -2 , and a realistic deceleration duration of 3.7 ms (Figure S2) by setting it to 13000 N m -1 .…”

“…Analogously, when nails are driven into wood, F p i increases with nail diameter. 20 While a relatively tight fit can be beneficial to graft-host healing due to increased post-insertional graft stability, such a tight fit requires relatively high impact to achieve the insertion. The effect of ΔR on OCG insertion biomechanics and resultant cartilage damage remains to be elucidated.…”

An osteochondral graft (OCG) is an effective treatment for articular cartilage and osteochondral defects. Impact of an OCG during insertion into the osteochondral recipient site (OCR) can cause chondrocyte death and matrix damage. The aim of the present study was to analyze the effects of graft-host interference fit and a modified OCG geometry on OCG insertion biomechanics and cartilage damage. The effects of interference fit (radius of OCG - radius of OCR), loose (0.00 mm), moderate (0.05 mm), tight (0.10 mm), and of a tight fit with OCG geometry modification (central region of decreased radius), were analyzed for OCG cylinders and OCR blocks from adult bovine knee joints with an instrumented drop tower apparatus. An increasingly tight (OCG - OCR) interference fit led to increased taps for insertion, peak axial force, graft cartilage axial compression, cumulative and total energy delivery to cartilage, lower time of peak axial force, lesser graft advancement during each tap, higher total crack length in the cartilage surface, and lower chondrocyte viability. The modified OCG, with reduction of diameter in the central area, altered the biomechanical insertion variables and biological consequences to be similar to those of the moderate interference fit scenario. Micro-computed tomography confirmed structural interference between the OCR bone and both the proximal and distal bone segments of the OCGs, with the central regions being slightly separated for the modified OCGs. These results clarify OCG insertion biomechanics and mechanobiology, and introduce a simple modification of OCGs that facilitates insertion with reduced energy while maintaining a structural interference fit. © 2017 Orthopaedic Research Society.
