The effect of cyclic knee motion on the elongation of four-strand hamstring autograft in anterior cruciate ligament reconstruction: an in-situ pilot study

Pretension of the viscoelastic graft by cyclic knee motion has been confirmed to decrease the graft creep and improve the outcome of anterior cruciate ligament (ACL) reconstruction. The purpose of the present ...

To systematically review the literature in an effort to compare the demographics and clinical outcomes of patients undergoing anterior cruciate ligament reconstruction (ACLR) with a hamstring tendon autograft (HT) versus an irradiated or nonirradiated hybrid autograft-allograft.

Authors: Lim CR, Henson T, Ebert J, Annear P Abstract BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) has a high incidence of re-tear in younger patients. Despite comparable functional outcomes, the incidence of re-tear using single and double bundle ACLR methods has not been well reported. AIM: To hypothesize that double bundle hamstring ACLR has a lower graft rupture rate compared with single bundle hamstring ACLR grafts in young patients. METHODS: One hundred and twelve patients

Publication date: Available online 7 January 2020Source: Arthroscopy TechniquesAuthor(s): Georg Brandl, Roman Christian Ostermann, Leo Pauzenberger, Christopher Lobo, Xaver FeichtingerAbstractScientific interest in optimizing outcomes after anterior cruciate ligament (ACL) reconstruction is ongoing, and some recent developments have focused on graft shape as one of the most important factors of anatomic graft placement. The double-bundle or fanlike structure of the native ACL seems to more closely restore normal function and control of rotational stability of the knee with implant-free or press-fit techniques, creating a f...

J Knee Surg DOI: 10.1055/s-0039-3402075Anterior cruciate ligament (ACL) reconstruction is considered as a successful orthopaedic procedure that attempts to help patients return to their preinjury level of activity. However, some patients may need to undergo revision surgery, and this potentially may be associated with certain surgery-specific or patient risk factors. Therefore, the purpose of this study was to assess the potential role of (1) demographics, (2) family history, (3) graft choice, (4) sport, and (5) mechanism of injury (contact vs. noncontact) in the risk for needing a revision ACL for improved clinical outcom...

ConclusionThis study demonstrated that some anthropometric measurements had a positive correlation with the hamstring graft length and diameter in male patients. Hence, these results provide preliminary support for the use of some anthropometric measurements in the preoperative planning and prediction of the hamstring graft length and diameter in anterior cruciate ligament reconstruction.

Conclusions: Bone-patellar tendon-bone and hamstring autografts both are viable options for ACL reconstruction. The occurrence of cyclops lesions is a potential complication that has not been previously compared between these two graft options. We found no statistically significant difference in the frequency of cyclops lesions between the two groups, minimizing any concern for an increased risk of a cyclops lesion when choosing BPTB autograft or hamstring autograft. Surgeons should be cognizant that the relative risk of a cyclops lesion is four times higher in female patients than in male patients with either graft. Le...

Publication date: Available online 18 December 2019Source: Arthroscopy TechniquesAuthor(s): Angelica Marie van Gogh, Xingguang Li, Gun Min Youn, Alyssa Alvarez, Sophia Yin, Moyukh O. Chakrabarti, Patrick J. McGahan, James L. ChenAbstractAnterior cruciate ligament (ACL) tears are detrimental to knee stability and normal function. Although the standard of treatment is an ACL reconstruction, technical improvements are sought to enhance clinical outcomes due to the appreciable failure rate. The use of autologous biologic substances as carriers of stem cells are desirable because of their multipotent properties. Traditionally, ...

ConclusionsQTB was recommended to be used even over the BPTB and 4S-HT autografts. BPTB autograft was more effective on restoring the knee stability than 4S-HT autograft. Non-irradiated allografts could be safely used as alternatives to autografts. However, artificial ligaments were not recommended for primary ACLR for significantly increased risk of knee laxity.

A recent investigation using the Swedish National Knee Registry large database showed that “The risk of ACL revision did not differ between HT and PT autografts in patients undergoing ACL reconstruction with a non-surgically treated MCL injury. However, the use of ST-G was associated with poorer two-year patient-reported knee function compared with the ST.” However, the Swedish Health care system is so unique that the results may not be universally applicable. Sweden provides universal health care, which is laudable, but there was an average delay of 314 days between injury and surgical intervention.
