In patients with chronic renal failure, spontaneous tendon rupture may occur due to degenerative changes in the tendon. Transosseous suture and suture anchor are commonly used for repair of quadriceps tendon rupture. But in chronic renal failure patients, the fixation of the repaired tendon is weak due to degenerative changes in the tendon, and decreased bone mineral density results in a relatively high rerupture rate. In this case, spontaneous quadriceps tendon rupture in a patient who has chronic renal failure with dialysis over 10 years was repaired with a newly designed transosseous suture method in order to increase contact of patella base and to reduce the rate of rerupture. Divide ruptured tendon arbitrarily into four layers using the anatomical structure of quadriceps tendon, then pull them out through the three vertical transosseous tunnels and tied them each. This procedure may be considered as another option in the case with high rerupture risk.
