“…Namely, in the previously reported techniques, the proximal attachment has been completely detached to visualize the femoral condyle. [12][13][14][15][16][17] In the present study, we performed this tissue-preserving surgery for the knees with a Type-I, II, or III ACL remnant tissue reported by Crain et al 6 Such knees existed in 55% of a total of 80 patients who underwent ACL reconstruction in our hospital in the same period. Crain et al reported that the knees with a Type-I, II, or III ACL remnant tissue existed in 58% of their 48 patients who underwent ACL reconstruction.…”

“…How can we accelerate restoration of better proprioception in ACL reconstruction? It is known that the ACL-injured knee frequently has a ligament remnant tissue, 6 in which mechanoreceptors and free neural ends are found. [7][8][9][10] Therefore, theoretically, there is a strong possibility that preservation of the ACL remnant tissue may be able to restore proprioceptive functions of the graft after ACL reconstruction.…”

Purpose: The purpose of this pilot study is to clarify the preliminary results of an anatomic double-bundle ACL reconstruction procedure with ligament remnant tissues. Methods:Using the trans-tibial technique, 2 doubled semitendinosus tendons were grafted into 4 tunnels created at the center of each bundle attachment, penetrating the ACL remnant tissue. Forty-four patients (27 men and 17 women) with an isolated ACL injury underwent ACL reconstruction using this procedure. The mean age of subjects was 29 years (range: 17-58). Postoperative clinical evaluations were performed at 16.6 months on average (range: 12 -23). Radiological evaluations were also performed to evaluate the tunnel location in the femur and the tibia. Results:The average operation time was 86 minutes (range: 72 -96) in the cases with ACL reconstruction only. Postoperatively, the mean anterior laxity was 0.7 mm. The postoperative pivot-shift test was negative in 81.8 % of the patients, while there were no patients evaluated as ++. No patients showed any extension or flexion deficit. There were no patients evaluated as "Nearly abnormal" or "Abnormal" under the IKDC evaluation. The tunnel angles of the 4 tunnels were identical to those reported in the previous study. Conclusions:The minimal 1-year clinical results of anatomic double-bundle ACL 3 reconstruction with ligament remnant tissue preservation were comparable to the previously reported results of the anatomic double-bundle reconstruction without remnant tissue preservation.

ABSTRACT:The regeneration of ligaments following injury is a slow process compared to the healing of many other tissues and the underlying mechanisms remain unknown. The purpose of the study was to evaluate the proliferative potential of ligaments by assessing telomere length within three distinct parts of human anterior cruciate ligament (ACL) obtained during ACL reconstruction: the macroscopically injured proximal part and macroscopically noninjured mid-and distal portions in eight subjects (age 28 ± 8 years). The mean telomere length in ACL was within normal range of values usually reported for other tissues indicating that the endogenous machinery responsible for the proliferative potential of ligament is not implicated in its poor healing capacity. The three ACL parts showed similar mean TRF lengths (distal part: 11.5 ± 0.8 kbp, mid-portion: 11.8 ± 1.2 kbp, proximal part: 11.9 ± 1.6 kbp) and there was no relationship between mean telomere length in ACL and the healing duration after rupture. This implies that despite the occurrence of ligament repair including a phase of intense cell proliferation the proliferative potential of ruptured ACL is not impaired. This knowledge is important for scientists and clinicians aiming to understand the mechanisms behind the low healing capacity of ligament.
