Background:
Pullout repairs of medial meniscus posterior root tears (MMPRTs) have many surgical options. However, there has been no reliable clinical study conducted to compare the superiority of each pullout repair technique. The current study hypothesized that pullout repairs using a modified Mason-Allen suture with FasT-Fix (F-MMA) would have several advantages in postoperative clinical outcomes and meniscal healing compared with single FasT-Fix. The aim of this study was to investigate the clinical usefulness of these two techniques in treating MMPRTs.
Methods:
Thirty-eight patients who had complete MMPRTs were included. All patients underwent transtibial pullout repairs. To compare the clinical usefulness between pullout repairs using single FasT-Fix and F-MMA techniques, patients were divided into two groups. Second-look arthroscopic evaluations of meniscal healing were performed at one year postoperatively. Clinical outcomes were assessed using: Lysholm and visual analogue scale (VAS) pain scores, and Knee Injury and Osteoarthritis Outcome Score (KOOS).
Results:
Single FasT-Fix and F-MMA pullout repairs improved clinical outcomes in patients with MMPRTs. At second-look arthroscopy, VAS pain, KOOS pain, and arthroscopic meniscal healing scores following F-MMA pullout repairs were superior to those after single FasT-Fix pullout repairs.
Conclusions:
This study demonstrated that F-MMA suture configuration obtained better meniscal healing and superior clinical outcomes compared with single FasT-Fix repairs in patients with MMPRTs. These results suggest that the F-MMA pullout repair may possibly reduce knee pain in arthroscopic treatments of MMPRTs.
Insights
The modified Mason-Allen suture with FasT-Fix (F-MMA) pullout repair technique demonstrated superior meniscal healing and better clinical outcomes for medial meniscus posterior root tears (MMPRTs) compared to single FasT-Fix repair.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Knee joint biomechanics
Background:
- Medial meniscus posterior root tears (MMPRTs) present diverse surgical repair options.
- A lack of comparative clinical studies hinders the determination of optimal pullout repair techniques for MMPRTs.
Purpose of the Study:
- To compare the clinical usefulness of modified Mason-Allen suture with FasT-Fix (F-MMA) versus single FasT-Fix pullout repair techniques for MMPRTs.
- To evaluate postoperative clinical outcomes and meniscal healing rates between the two techniques.
Main Methods:
- A prospective study involving 38 patients with complete MMPRTs undergoing transtibial pullout repairs.
- Patients were divided into two groups: single FasT-Fix and F-MMA repair.
- Second-look arthroscopy at one year assessed meniscal healing; clinical outcomes evaluated using Lysholm, VAS pain, and KOOS scores.
Main Results:
- Both single FasT-Fix and F-MMA pullout repairs led to improved clinical outcomes in MMPRT patients.
- The F-MMA technique showed superior results in VAS pain, KOOS pain, and arthroscopic meniscal healing scores compared to single FasT-Fix.
Conclusions:
- The F-MMA suture configuration achieved superior meniscal healing and clinical outcomes for MMPRTs compared to single FasT-Fix.
- F-MMA pullout repair may offer reduced knee pain in arthroscopic treatment of MMPRTs.
