Purpose: Cadaveric studies have shown that deficiency of the posterior horn of the medial meniscus (PHMM) increases strain on the anterior cruciate ligament (ACL) graft. However, its influence on the clinical and radiological outcome after ACL reconstruction is less discussed and hence evaluated in this study. Materials and Methods: This study included 77 cases of ACL reconstruction with a minimum 18-month follow-up. Of the 77 cases, 41 patients with intact menisci were compared clinically and radiologically with 36 patients with an injury to the PHMM that required various grades of meniscectomy...

Preoperative prediction of hamstring tendon lengths and graft diameter for anterior cruciate ligament (ACL) reconstruction enables better preoperative planning. Presently, no study exists for Indian population where both derivation and verification of a mathematical equation for accurate prediction of hamstring graft dimensions have been done. This study was conducted in two phases: First phase ( derivation cohort): devoted to the study of correlation of length of hamstring tendons and graft diameter with various anthropometric measurements in 123 patients undergoing ACL reconstruction...

BACKGROUND: Athletes often are cleared to return to activities 6 months after anterior cruciate ligament (ACL) reconstruction; however, knee function measures continue to improve up to 2 years after surgery. Interventions beyond standard care may facilitate successful return to preinjury activities and improve functional outcomes. Perturbation training has been used in nonoperative ACL injury and preoperative ACL reconstruction rehabilitation, but has not been examined in postoperative ACL reconstruction rehabilitation, specifically return to sport rehabilitation...

BACKGROUND: Movement asymmetries during walking are common after anterior cruciate ligament (ACL) injury and reconstruction and may influence the early development of posttraumatic osteoarthritis. Preoperative neuromuscular training (like perturbation training, which is neuromuscular training requiring selective muscle activation in response to surface perturbations) improves gait asymmetries and functional outcomes among people who are ACL-deficient, but the effect of postoperative perturbation training on gait mechanics after ACL reconstruction is unknown...

PURPOSE: The position of the osseous tunnels and graft during anterior cruciate ligament (ACL) reconstruction has been the subject of multiple studies aiming for either anatomical placement or an alternative. The assessment of these positions, using post-operative imaging, is therefore of interest to the surgeon in both the evaluation of surgical performance and surveillance of potential complications. The purpose of this review is to identify the optimal use of imaging in both the surveillance of clinical practice and in planning revision surgery...

In recent decades, arthroscopic meniscal allograft transplantation (MAT) has been refined as a robust option for the treatment of evolving unicompartmental tibiofemoral arthrosis in the setting of meniscal deficiency. It is imperative that the MAT be performed in a knee with anatomic stability and alignment to reduce aberrant biomechanical forces experienced by the allograft tissue to maintain its durability. Thus, in an anterior cruciate ligament (ACL)-deficient knee, ACL reconstruction (ACLR) must be performed to restore the stable knee environment for the MAT to succeed...

Anterior cruciate ligament (ACL) tears are among the most common sports-related injuries. Although studies have reported reliable outcomes with allograft tissue, several studies have shown a higher failure rate in younger patients. Although ACL graft augmentation has been met with varying levels of success, internal bracing of an allograft represents a promising area in ACL reconstruction. The purpose of this article is to detail allograft preparation involving a collagen-coated, ultrahigh-molecular-weight polyethylene/polyester suture tape as an internal brace augmentation for ACL reconstruction using the all-inside ACL GraftLink Technique (Arthrex, Naples, FL)...

Growing participation in youth athletics has resulted in increased numbers of anterior cruciate ligament (ACL) injuries in skeletally immature patients. Use of autogenous graft material has been associated with improved graft survival. However, pediatric patients sometimes possess hamstring tendons that produce smaller-diameter grafts than those prepared with adult autogenous materials. Smaller-diameter grafts may predispose younger patients to graft failure. We describe a technique that increases the diameter of the ACL construct through the use of an 8-strand autologous hamstring tendon graft...

Single-bundle (SB) anterior cruciate ligament (ACL) reconstruction is increasingly used in a large number of patients and it allows obtaining very good clinical and subjective results; however, functional tests show a persistent rotational instability. Biomechanical studies seem to indicate that double-bundle (DB) ACL reconstruction allows to obtain increased anterior and rotational stability compared with SB. The aim of this prospective randomized controlled study was to compare the clinical outcome and the possible osteoarthritic evolution of patients treated either with a SB (freehand transtibial femoral tunnel) or with a DB technique (outside-in for posterolateral femoral tunnel/inside-out for anteromedial femoral tunnel) at a final follow-up of 6 years...
