Summary
There is significant improvement in functional scores and most of our patients returned to preinjury activity level with good muscle strength with low rate of complications. In our experience CQT autograft is a suitable alternative, low morbid thicker rigid graft of choice for patients undergoing ACLR.

Abstract
Purpose
This study provides an up-to-date review on recent techniques and outcomes in anterior cruciate ligament (ACL) reconstruction using partial thickness CQT graft without bone plug.
Methods
This is a Retrospective cohort study of 89 patients undergoing ACL reconstruction using partial thickness CQT graft without bone plug in 3-center of Mumbai (INDIA) complying with inclusion criteria. Functional assessment based on Lysholm, IKDC, KOOS and Tegner scores. Subjective assessment done using variables like Anterior knee pain, giving way, patellofemoral crepitus and donor site morbidity. Objective data included Lachman test, Pivot-shift test, Range of motion, Numbness or Skin irritations. Complications if any were also recorded.
Results
89 among 114 CQT ACLR patients were included and all are followed for minimum 2 years and maximum 3 years postoperatively. There were 58 men and 31 women with mean age 26yrs (17 to 46).
The mean preinjury and preoperative post-injury Lysholm Knee Scores were 93.56±7.52 and 64.08±11.64 respectively, while the respective mean scores at one and two years postoperatively were 89.63±3.27 and 94.05±1.81.
The mean Tegner preinjury and preoperative post-injury scores were 7 (3 to 9) and 3 (0 to 6), respectively, while the respective mean scores at one and two years postoperatively were 6 (3 to 8) and 7 (3 to 9).
The mean KOOS scores at preinjury versus two years postoperatively were: symptoms (96 vs 84); pain (94 vs 87); activities of daily living (97 vs 91), sports and recreation function (84 vs 71), and quality of life (82 vs 69), respectively (p < 0.001).
Preoperatively 51 (57%) had grade-3 laxity and 38 (43%) had grade-4 laxity which shows significant improvement to 83 (93%) grade-1 and 6 (7%) grade 2 laxity postoperatively.
In term of Extensor strength, 68 (76%) patients achieved >90%, 18 (20%) achieved 80-90% strength while in terms of flexor strength 73 (82%) achieved >90% and 14 (16%) 80-90% strength. VAS score is decreased from 1.158(SD=1.56) to 0.21(SD=0.41) and 0.14(SD=0.35) at 12 and 24 months respectively.
At final follow-up 81(91%) patients gained full ROM, 6 nearly normal and only 2 patient had 6 degree of Extension loss considered as abnormal rating.
12(13.4%) patients presented with anterior knee pain, 2 had graft site collection of hematoma, 2 had traumatic graft rerupture, while 5 had numbness over upper outer quadrant of patella and suprapatellar area. 7 patients had scar irritation at harvest site which progressively resolved.
