Summary
The modified Mason-Allen (MMA) and two simple stitches (TSS) techniques for medial meniscus posterior root tear repair show similar clinical outcomes and healing. Further research is needed to determine long-term differences between these suture methods.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Sports Medicine
Background:
- Medial meniscus posterior root tears (MMPRT) can be repaired using various suture techniques.
- The modified Mason-Allen (MMA) technique is proposed as an alternative to the conventional two simple stitches (TSS) technique for MMPRT repair.
- MMA is suggested due to its potentially superior biomechanical properties.
Purpose of the Study:
- To conduct a systematic review and meta-analysis comparing MMA and TSS techniques for MMPRT repair.
- To evaluate differences in clinical outcomes, medial meniscal extrusion (MME), and postoperative healing between MMA and TSS.
- To identify the optimal suture configuration for MMPRT repair.
Main Methods:
- A systematic review and meta-analysis were performed following PRISMA criteria.
- Searches were conducted in Cochrane, PubMed, Medline, and Embase databases using relevant keywords.
- Data on patient-reported outcomes, MME, healing, and osteoarthritis progression were extracted and analyzed.
Main Results:
- Six studies with 291 patients (160 MMA, 131 TSS) were included.
- No significant differences were found between MMA and TSS in patient-reported outcomes at 14.2 months.
- Postoperative MME and meniscal healing rates were similar for both techniques.
Conclusions:
- Both MMA and TSS suture configurations demonstrate equivalent clinical outcomes, MME, and postoperative healing for MMPRT repair.
- The TSS technique may offer benefits regarding a shorter learning curve and operative time.
- Further randomized controlled trials with larger sample sizes and longer follow-up are necessary to definitively assess differences, especially concerning chondral degeneration and osteoarthritis.

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:
01:15Mass Spectrometry of Amines
In mass spectroscopy, amines undergo fragmentation to give parent ions with odd molecule weights. This observed mass spectrum follows the nitrogen rule; a molecule with an odd number of nitrogen atoms produces a molecular ion with an odd molecular weight. Amines undergo fragmentation through α cleavage, producing nitrogen-containing cations—iminium ions—and alkyl radicals. Mass spectra of aromatic and cyclic aliphatic amines exhibit strong molecular ion peaks, but acyclic aliphatic amines show...
01:03Mass Spectrometry: Alcohol Fragmentation
Alcohols (R-OH) ionize to lose one non-bonded electron from the oxygen atom, forming molecular ions. Due to their tendency to fragment rapidly, the intensity of the molecular ion peak in the mass spectrum is weak or sometimes absent. The fragmentation patterns for alcohols occur in two ways, i.e. ⍺-cleavage and dehydration. During ⍺-cleavage, the bond at the ⍺-position adjacent to the hydroxyl group cleaves to give a resonance-stabilized cation and a radical. However, intramolecular dehydration...
00:55Mass Spectrometry: Amine Fragmentation
Amines can be identified using mass spectroscopy based on their characteristic fragmentation patterns. The molecular ions of amines undergo fragmentation via ⍺-cleavage. The ⍺-cleavage of the carbon-carbon bonds in amines generates an alkyl radical and resonance-stabilized nitrogen-containing cation.
In amines, the number of nitrogen atoms affects the mass of the molecular ion, which is described by the nitrogen rule of mass spectrometry. This rule states that a compound containing a single or...

01:01Mass Spectrometry: Carboxylic Acid, Ester, and Amide Fragmentation
The fragmentation patterns observed for compounds such as carboxylic acids, esters, and amides in the mass spectra include ⍺-cleavage and McLafferty rearrangement. Fragmentation by ⍺-cleavage preferentially occurs at the carbon-carbon bond at the ⍺-position next to the carboxylic group to generate a neutral radical and a cation. Long chain compounds with hydrogen at their γ-carbon undergo McLafferty rearrangement to give a radical cation and a neutral alkene.
For example, the fragmentation of...

01:18Effects of EDTA on End-Point Detection Methods
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
