Anterior knee pain in anterior cruciate ligament reconstruction using bone-patellar tendon-bone graft and autologous bone grafting

Table 1 Distribution of total Kujala anterior knee pain score

Kujala score range	Number of patients	Percentage
100	5	20.8
95-99	13	54.2
90-94	4	16.7
86-89	2	8.3

Functional outcome: Kujala Anterior Knee Pain Score (scale from 0 to 100). A score of 100 indicates no complaint or functional limitation, while threshold of clinically significant anterior knee pain is widely considered to be below 85.

Table 2 The pain specific subcomponent of Kujala Anterior Knee Pain Score

Pain score	Number of patients	Percentage
10/10	23	95.8
8/10	1	4.2

The Kujala score pain subcomponent scores range from 10 (no pain) to 0 (severe, continuous pain).
