Patient Demographics
We retrospectively reviewed 442 patients who underwent arthroscopic ACL reconstruction by the senior orthopaedic surgeon (K.H.Y.) between March 2000 and February 2006 and were followed up for more than 2 years. Among these patients, we excluded cases with fracture, those with multiple-ligament injury in the ipsilateral knee, those that had undergone meniscal transplantation or revision surgery after ACL reconstruction, and those with concomitant fracture or ligament injury in the contralateral
Clinical
The preoperative ROM was not different among the 3 groups (P > .05), but the BPTB group and TA group showed greater ROM than the HA group at last follow-up (P = .028 and P < .001, respectively) (Table 3). There was no significant difference in Lachman test, pivot-shift test, and KT-1000 arthrometric test at last follow-up (P > .05) (Table 4, Table 5). For the IKDC knee score, there was also no difference in the distribution of each grade among the 3 groups (P > .05) (Table 6). At a mean of 4
Discussion
Many authors have described satisfactory results of ACL reconstruction using various types of allografts without side effects such as immunogenic reaction, and some authors have reported that allograft presented better results than autograft.11, 14 However, recently, some studies reported worse results after ACL reconstruction with allograft. Prodromos et al.12 reported that autograft presented better stability in their meta-analysis of autograft versus allograft in ACL reconstruction, and
Conclusions
There was no difference in knee stability measured by physical and quantitative tests among BPTB allografts, TA allografts, and HA autografts used for ACL reconstruction except that the allograft groups showed greater postoperative ROM than the autograft group. However, the HA autograft group had better synovial coverage than the 2 allograft types on second-look arthroscopy, and the group with better synovial coverage on second-look arthroscopy presented better clinical results on the IKDC

2021, KneeCitation Excerpt :These features are in agreements with those described by other groups [3,5,35]. Furthermore, a number of studies reported allowing their patients with ACLR who completed physical rehabilitation to return to sports activities when then the LSI of quadriceps strength was ≥80% [36,37]. In this study, the corresponding LSI was 88.1%, suggesting that their quadriceps strength was relatively good compared with those of previous studies.

2019, KneeCitation Excerpt :First, no gold standard modality was used for the characterization and comparison of ALL injuries suggested by MRI findings. Although MRI is a method with great potential, the injury criteria were established arbitrarily on the basis of the experience of the authors and previous studies that evaluated this structure [3–5,7–10,17,28]. Second, the lack of association between the location of the ALL and the instability might have been a source of a type 2 error due to the sample size used, and this should also be considered as a limitation of this study.
