Summary
Arthroscopic subscapularis tendon repair offers potential benefits over open surgery. This study presents a novel arthroscopic technique using an angled suture passer for improved outcomes in rotator cuff repair.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Musculoskeletal Research
Background:
- Arthroscopic rotator cuff repair has surpassed open procedures due to technological advancements.
- Subscapularis tendon tears, often partial or associated with other rotator cuff injuries, are more prevalent than commonly recognized.
Purpose of the Study:
- To present a refined arthroscopic technique for subscapularis tendon repair.
- To potentially improve upon existing arthroscopic methods for rotator cuff injuries.
Main Methods:
- A novel arthroscopic technique for subscapularis tendon repair is described.
- The technique utilizes an angled suture passer and a single anterior working portal.
Main Results:
- The presented technique aims to optimize operative time, reduce scarring, and minimize postoperative pain.
- Long-term comparative outcome data between arthroscopic and open subscapularis repair are currently lacking.
Conclusions:
- The described arthroscopic technique offers a promising approach for subscapularis tendon repair.
- Further studies are needed to compare the long-term efficacy of this technique against open repair.

Mismatch Repair
6.6K
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.

Hepatic Portal System
6.1K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Overview of DNA Repair
33.8K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Base Excision Repair
26.4K
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.

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:
