XXXX : impact on extensor mechanism complaints after use of a bone-tendon-bone graft for anterior cruciate ligament reconstruction.

@entity1 @entity154 @entity158
In a prospective study, the impact of refilling @entity154 at the tibial tuberosity and patella on extensor mechanism complaints was studied after anterior cruciate ligament reconstruction with a bone-tendon-bone ligament graft. A conventional cannulated drill was sued in @entity1 of group 1 (n = 62), and an oscillating hollow saw was used in group 2 (n = 70) for drilling and removing bone material from the tibial tunnel. On completing the procedure in the @entity1 in group 2, the bone material removed was inserted into the bony @entity154 at the tibial tuberosity and the patella. In both groups, the extensor mechanism was closed using loose sutures. Both groups underwent the same postoperative therapy regimen. All @entity1 underwent clinical and radiographic follow-up after approximately 34 months. In this follow-up, no differences with regard to knee function as assessed by the IKDC rating scale and KT-1000 measurements were found between the 2 groups. The rate of mild to severe patellofemoral complaints was 31% (41 @entity1 ). Complaints related to the @entity154 as assessed by kneeling and squatting on the operated knee were described by 25 @entity1 (18.9%). No significant difference between the groups with and without refilling of the @entity154 was observed, and the overall subjective ratings on a visual analog scale (VAS) (0 = no @entity158 , 10 = severe @entity158 ) for kneeling and squatting were 5.57 and 3.69, respectively. Follow-up time was identified as the critical parameter for problems related to the extensor mechanism, such as complaints in kneeling and squatting, with hardly any problems observed after 2 years. On the other hand, anterior knee @entity158 correlated significantly with the residual limitation of motion.
