Sažetak
Proven benefits of early active mobilisation for intra-synovial flexor tendon repairs have inducted new criteria for a ‘perfect suture’. This study has examined different variations of modified Kessler's suture, which could fulfil the new criteria. A total of 93 swine extensor tendons were transected, repaired and tested using a dynamometer with constant rate of extension. The first part of study tested clinically the most used modified Kessler suture, a variation of double modified Kessler suture and intact tendons as a control group. Further variations in the second part of study were due to type of suture, location and number of the knots and type of peripheral suture. According to the results, the tested version of double modified Kessler suture with crossed peripheral suture was the strongest one among all tested variations. The ultimate force for the authors preferred modification of the double modified Kessler (DMK) is significantly higher than modified Kessler suture. The version of DMK with crossed peripheral suture is the strongest one among all tested variations. The lowest strength manifests variation with two knots between tendon ends. The variations with interlocked and outsided knot or monofilament tread are not statistically significant regarding ultimate force. The frequency of suture failure events (suture pull out or tendon and/or suture rupture) is equal respecting braided or monofilament suture. The preferred modification of the double modified Kessler (DMK) suture with crossed peripheral suture is the strongest one among all tested variations and could achieve, concerning range of force, early active mobilisation. Further variations due to the type of thread and location, type and number of the knots did not show statistical significance.
