Summary
Anterior cruciate ligament (ACL) repair using FiberTape sutures and an adjustable cortical button offers outcomes comparable to reconstruction for specific patient groups. However, younger athletes may experience higher failure rates with this ACL repair technique.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Anterior cruciate ligament (ACL) restoration involves repair versus reconstruction.
- ACL rupture necessitates restoration for knee function.
- ACL repair is indicated for acute tears, specific tear types, and older, less active patients.
Purpose of the Study:
- To present a novel ACL repair technique using FiberTape sutures and an adjustable cortical button.
- To evaluate the outcomes of this ACL repair method.
Main Methods:
- Identification of ACL tear.
- Femoral wall preparation and creation of drill tunnels.
- Passage of FiberRing sutures through the ACL.
- Insertion of ACL Tightrope and adjustable cortical button.
- Use of FiberTape sutures as an internal brace.
Main Results:
- ACL repair with Tightrope implants shows comparable functional knee scores to reconstruction.
- Patient-reported outcomes (IKDC, KOOS, Lysholm) are similar between repair and reconstruction.
- Younger patients undergoing ACL repair demonstrate a higher failure rate compared to reconstruction.
Conclusions:
- ACL repair is a viable adjuvant treatment for acute femoral-sided ACL tears.
- Caution is advised for younger, high-activity athletes due to potential higher failure rates.
- Adjustable cortical button fixation minimizes bone loss while ensuring adequate fixation.

01:54Base Excision Repair
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

01:02Long-patch Base Excision Repair
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
02:04Fixing Double-strand Breaks
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...
02:31Homologous Recombination
The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...
02:37Restarting Stalled Replication Forks
DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart, a...
01:20Mismatch Repair
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
