    PURPOSE: To evaluate the optimal number of additional half-hitches for achieving an optimal knot-holding capacity (KHC) of lockable sliding knots. METHODS: Four configurations of arthroscopic knots (Duncan loop, Field knot, Giant knot, and SMC knot) were tested for their knot-holding capacity. For each knot configuration, 6 sequential knots were made including the initial sliding knot and additional 5 knots by augmenting one half-hitch at a time. Each added half hitch were in reversing half-hitches with alternate posts (RHAPs) fashion. For each sequential knot configuration, 12 knots were made by No. 2 braided sutures. On the servo-hydraulic material testing system (Instron 8511, MTS, Minneapolis, MN), cyclic loading, load to clinical failure (3 mm displacement), load to ultimate failure, and mode of failure were measured. Statistical analysis was performed using 2-way ANOVA analysis and regression analysis. RESULTS: Most of the initial loop without additional half-hitch showed dynamic failure with cyclic loading. However, after one additional half-hitch, three (SMC, Field, and Giant) knots resisted the dynamic cyclic load. After 2 additional half-hitches, Duncan loop was secured without slippage from the cyclic loading test. The mean displacement after the end of cyclic loading decreased with each additional half-hitches. Especially, SMC and Giant knot reached plateau to 0.1 mm or less displacement after one additional half-hitch, whereas Field and Duncan loop needed 3 additional half-hitches to reach the plateau. The SMC and Duncan knots needed 1 additional half-hitch to reach greater than 80N at clinical failure, whereas the other 2 knots needed 2 additional half-hitches. For the load exceeding 100N for clinical failure, the SMC knot required 3 additional half-hitches and the other three knots needed 4 additional half-hitches. Addition of more than 3 half-hitches did not increase the load to clinical failure in the SMC knot. However, load to clinical failure increased up to 4 additional half-hitches in the other 3 knots (p
