Successful ACL reconstruction with a variant of the pes anserinusEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract An anatomical variant of the pes anserinus encountered during anterior cruciate ligament reconstructive surgery which has not been previously described is discussed. During routine harvesting, the sartorius fascia was incised and the semitendinosus and gracilis tendons were identified. At the distal portion, it was noted that each tendon gave off an additional tendinous slip. The slip from the semitendinosus tendon had attached to the gracilis tendon and vice versa, thereby creating a double pes anserinus. This variant was used to construct the graft, and at 1 year review the patient had return...

The resident’s ridge as an arthroscopic landmark for anatomical femoral tunnel drilling in ACL reconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The purposes of this study were to establish the technique to arthroscopically identify the resident’s ridge without bony notchplasty even in patients with chronic ACL insufficiency and to elucidate if the ridge could be used as a landmark for anatomical femoral tunnel for ACL graft. There were 50 consecutive patients undergoing arthroscopic ACL reconstruction. With the thigh kept horizontal using a leg holder, a meticulous effort was made to find out a linear ridge running proximo-distal in a posterior one-third of the lateral notch wall, after removal of superficial soft tissue with radiofrequen...

Peroneal nerve damage by bicortical tibial screw in ACL reconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Arthroscopically assisted anterior cruciate ligament reconstruction is regarded as a minimally invasive surgery with low morbidity but complications still occur. Reports of neurovascular injuries related to graft harvesting, tunnel placement, or graft fixation are limited. A rare case of peroneal nerve injury related to hardware used for graft fixation in the tibial in a 28-year-old female patient who underwent an anterior cruciate ligament reconstruction surgery using a patellar tendon graft (bone-tendon-bone graft) is presented. Post-operatively, the patient presented with clinical signs of perone...

The transtibial versus the anteromedial portal technique in the arthroscopic bone-patellar tendon-bone anterior cruciate ligament reconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The transtibial (TT) drilling of the femoral tunnel in the bone-patellar tendon-bone (BPTB) anterior cruciate ligament (ACL) reconstruction was found to place the tunnel non-anatomically. The use of the anteromedial portal (AMP) for the femoral drilling would provide the surgeon with more freedom to anatomically place the tunnel in the real femoral ACL footprint. The purpose of this study was to compare the clinical outcomes of BPTB ACL reconstruction using the AMP or the TT technique for the femoral tunnel drilling. A Medline search was not able to identify any study directly comparing the clinical...

Knee flexor strength after ACL reconstruction: comparison between hamstring autograft, tibialis anterior allograft, and non-injured controlsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study compared the mean peak isometric knee flexor torque of the following three groups: subjects 2 years following ACL reconstruction using semitendinosus–gracilis autografts (Group 1), subjects 2 years following ACL reconstruction using tibialis anterior allografts (Group 2), and a non-injured, activity-level-matched control group (Group 3). We hypothesized that Group 1 would have greater mean involved lower extremity peak isometric knee flexor torque deficits than the other groups. Handheld dynamometry with subjects in prone and the test knee at 90° flexion was used to determine bilateral peak iso...

We read the letter by Drs. Lorenz, Illingworth, and Fu about our recent article with attention. We thank them for their comments that add complementary information to our work as they describe the diagnosis of partial anterior cruciate ligament (ACL) ruptures. This was not, however, the purpose of our article. As readers most certainly will have observed, our article was mainly based on the histologic evolution of such ruptures, which have been very accurately described by Murray et al., but was never clearly identified during arthroscopic examination in the context of ACL reconstruction in humans.

Has Platelet-Rich Plasma Any Role in Anterior Cruciate Ligament Allograft Healing?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: At this time, the therapeutic role of PDGF in ACL reconstruction remains unclear. The use of PDGF, on the graft and inside the tibial tunnel, in patients treated with bone–patellar tendon–bone allografts has no discernable clinical or biomechanical effect at 2 years' follow-up. More clinical studies will be needed to show the efficacy and use of these factors in daily practice in ACL reconstruction.Level of Evidence: Level I, prospective, randomized, double-blind study.

Three-Dimensional In Vivo Patellofemoral Kinematics and Contact Area of Anterior Cruciate Ligament–Deficient and –Reconstructed Subjects Using Magnetic Resonance ImagingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: ACL injuries alter patellofemoral kinematics including patellar tilt and patellar lateral translation, but ACL reconstruction with hamstring or allograft restores altered patellar tilt. ACL injuries reduce the patellofemoral contact area at both the extended and flexed positions, but ACL reconstruction enlarges the patellofemoral contact area at extension and restores the normal contact area at low angles of flexion.Level of Evidence: Level III, case-control study.

The effects of anterior cruciate ligament lesion on the articular cartilage of growing goats.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Treatment of anterior cruciate ligament (ACL) injury in skeletally immature patients is controversial. The growth plate could be damaged if treated with the reconstruction techniques used to treat instability in adults. For this reason, many authors postpone surgical treatment until skeletal maturity, but the acceptable length of time that treatment can be postponed without causing irreversible damage to the articular cartilage in children with ACL injury is unknown. Until now, no studies have described the pathological findings and the evolution of the lesions of the articular cartilage during the growing period. For ...

Effect of Anterior Cruciate Ligament Reconstruction and Meniscectomy on Length of Career in National Football League Athletes: A Case Control StudyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion A history of meniscectomy, but not ACL reconstruction, shortens the expected career of a professional football player. A combination of ACL reconstruction and meniscectomy may be more detrimental to an athlete’s durability than either surgery alone. Further research is warranted to better understand how these injuries and surgeries affect an athlete’s career and what can be done to improve the long-term outcome after treatment.

Graft Orientation Influences the Knee Flexion Moment During Walking in Patients With Anterior Cruciate Ligament ReconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion The negative correlation between peak external knee flexion moment during walking and the coronal angle of the anterior cruciate ligament graft indicates that as the anterior cruciate ligament graft is placed in a more vertical coronal orientation, patients reduce their net quadriceps usage during walking. Clinical Relevance This finding supports the hypothesis that graft placement plays a critical role in the restoration of normal ambulatory mechanics after anterior cruciate ligament reconstruction and thus could provide a partial explanation for the increased incidence of premature osteoarthritis at long-term...

Electromechanical Delay of the Knee Flexor Muscles Is Impaired After Harvesting Hamstring Tendons for Anterior Cruciate Ligament ReconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion The results showed that harvesting the semitendinosus and gracilis tendons for anterior cruciate ligament reconstruction significantly increased the electromechanical delay of the knee flexors. Increased hamstring electromechanical delay might impair knee safety and performance by modifying the transfer time of muscle tension to the tibia and therefore affecting muscle response during sudden movements in athletic activities. However, further investigation is required to identify whether the increased electromechanical delay of the hamstrings can actually influence optimal sports performance and increase the risk...

Effect of Cryoprotectant Incubation Time on Handling Properties of Allogeneic Tendons Prepared for Knee Ligament ReconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study concludes that an 8-h cryoprotectant incubation time is detrimental to qualitative allogeniec tibialis posterior tendon properties. Both groups tended to improve with longer rehydration times, however the 8-h incubation group remained actively dehydrated as evidenced by its smaller diameter and poorer tissue handling properties. Suboptimally rehydrated tendons would be more likely to accrue damage during allograft preparation or during implantation. (Source: Journal of Biomaterials Applications)

Abstract Sixty-eight patients were clinically evaluated preoperatively, 3, 5, 7, 9 months, 1 and 2 years after ACL reconstruction, 34 with patellar tendon graft, 34 with hamstring graft. Outcome regarding graft choice and anterior knee laxity (P = 0.04) was in favour of patellar tendon graft. Hamstring graft led to a larger laxity, 2.4 mm compared with patellar tendon graft, 1.3 mm at 1 year and 2.5 mm and 1.5 mm, respectively, at 2 years (P = 0.05). There was a significant difference in rotational knee stability in favour of the patellar tendon graft...

How to avoid the risk of intraoperative cartilage damage in anatomic four tunnel double bundle anterior cruciate ligament reconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Double bundle (DB) anterior cruciate ligament (ACL) reconstruction is technically demanding. In order to create four anatomical anteromedial (AM) and posterolateral (PL) bone tunnels many surgeons adopt new ways of tibial and femoral bone tunnel drilling. From surgical experience, these technical changes might increase the risk for intraoperative pitfalls. An intraoperative articular cartilage damage to the medial femoral condyle or the medial tibial plateau could be disastrous for the patient. It may be caused by an insufficient anteromedial portal technique for femoral AM and PL bone tunnel drilli...

Intraoperative complications using the Bio-Transfix femoral fixation implant in anterior cruciate ligament reconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report on three cases of deformation and back out of the Bio-Transfix implant over the lateral, distal femoral cortex, with failure of the passing wire when advancing the graft into the femoral tunnel in one of these patients. Two of the patients presented with symptoms of iliotibial band friction syndrome, while the third patient was asymptomatic. The graft had clinically integrated demonstrating AP and rotational stability. The symptoms relieved after removal of the failed Bio-Transfix implants in the symptomatic patients. The aetiology of the implant failure and the alternative methods to avoid such complication...

Independent Drilling Outperforms Conventional Transtibial Drilling in Anterior Cruciate Ligament ReconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion An independent drilling method can produce tunnels with superior function compared with tunnels produced by a conventional transtibial drilling method. Clinical Relevance Single-bundle anterior cruciate ligament reconstructions will be improved if grafts are centered in their anatomical insertions by an independent drilling method versus grafts placed by a conventional transtibial drilling method.

Osteointegration of soft tissue grafts within the bone tunnels in anterior cruciate ligament reconstruction can be enhancedEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Anterior cruciate ligament reconstruction with a soft tissue autograft (hamstring autograft) has grown in popularity in the last 10 years. However, the issues of a relatively long healing time and an inferior histological healing result in terms of Sharpey-like fibers connection in soft tissue grafts are still unsolved. To obtain a promising outcome in the long run, prompt osteointegration of the tendon graft within the bone tunnel is essential. In recent decades, numerous methods have been reported to enhance osteointegration of soft tissue graft in the bone tunnel. In this article, we review ...
