A Preclinical Model to Study the Influence of Graft Force on the Healing of the Anterior Cruciate Ligament Graft

In conclusion, we have developed a novel ACL reconstruction model that can reproducibly produce two ACL graft force patterns. This model would permit further research on how ACL graft forces may affect subsequent graft healing, maturation, and function.

CONCLUSION: Adolescent male ACLR patients with BTB and HS autografts demonstrated significant deficits in quadriceps and hamstring strength, respectively, at 6-9 months post-operatively. Minimal lower extremity strength deficits were demonstrated in pediatric male ACLR patients undergoing ITB harvest. KEY WORDS: Autograft, young ACL reconstruction, return to play, pediatrics.

Authors: Ueda Y, Matsushita T, Shibata Y, Takiguchi K, Kida A, Araki D, Kanzaki N, Hoshino Y, Ono R, Sakai Y, Kuroda R Abstract CONTEXT: Some studies have discussed postoperative quadriceps strength recovery after anterior cruciate ligament reconstruction (ACLR). However, the effect of preoperative quadriceps strength deficit on longitudinal postoperative quadriceps strength recovery after ACLR with hamstring autograft is unknown. OBJECTIVE: To reveal the longitudinal postoperative quadriceps strength recovery after ACLR with hamstring autograft among patient groups stratified by preoperative quadriceps strengt...

Authors: Mariani PP, Laudani L, Rocchi J, Giombini A, Macaluso A Abstract CONTEXT: All rehabilitative programs before ACL reconstructive surgery, which are focused on recovery of proprioception and muscular strength, are defined as prehabilitation. While it has shown that prehabilitation positively affects the overall outcome after ACL reconstruction, it is still controversial whether enhancing preoperatively quadriceps strength has some beneficial effect on postoperative strength, mainly during the first period. OBJECTIVE: To determine whether there is any relationship between pre- and early postoperative quad...

Few studies in the literature show results with more than 20  years of follow-up after anterior cruciate ligament reconstruction (ACLR). The main purpose of this retrospective study was to describe knee-specific quality of life, functional results and prevalence of osteoarthritis (OA) of the knee in patients with ACLR using bone–patellar tendon–bone (BP TB) autograft with ultra-long-term follow-up.

Amnion has the potential to decrease adhesions and possibly protect anterior cruciate ligament (ACL) grafts along with increasing vascularization by acting as a scaffold. Bone marrow concentrate containing mesenchymal stem cells combined with Allosync Pure (Arthrex, Naples, FL) injected into ACL tunnels has the potential to increase the speed and quality of graft bone incorporation, especially when used in the setting ...

ConclusionsUsing the CaP hybridization method for QTB graft in ACL reconstruction was safe and feasible in the clinical trial. Moreover, this method may improve clinical outcomes. In the future, it is necessary to verify the effect of the CaP hybridization method for QTB graft in ACL reconstruction.

A harvested hamstring autograft that is too small is a technical challenge for an effective anterior cruciate ligament reconstruction. One potential solution is to assemble the graft differently to maximize the diameter and length of the graft. Compared with the traditional, all-inside, 4-strand graft preparation, alternative graft constructs could be further explored and evaluated.
