Abstract

Background: The menisci are crucial for knee joint health and longevity, but injuries to them are common, accounting for up to seventy-five percent of internal knee complications.
Aim and objectives: To assess the outcome of Arthroscopic meniscal repair using the outside-in technique and to evaluate its impact on meniscal healing at 3-6 months of follow-up.
Patients and methods: This prospective research involves twenty patients with meniscal tear surgery in AL-Azhar University Hospitals (Al-Hussein and Bab Alshaaria Hospitals) and Nasser Institute for research and treatment between May 2023 and May 2024.
Results: Post-operative 3 months and 6 months Lysholm scores and Post-operative 6 months IKDC scores showed significant increases compared to preoperative scores, p-value < 0.001. There was a statistically significant increase in preoperative Lysholm score (p-value = 0.002), 3 months (p-value = 0.013), and 6 months (p-value = 0.023) post-operative Lysholm score in patients with 10-15 mm tears when compared with patients with 16-20 mm tears. There was a statistically significant (p-value = 0.016) increase in preoperative Lysholm score in acute patients compared with chronic patients. Also, there was a statistically significant (p-value < 0.001) increase in 3 months and 6 months post-operative Lysholm score in Acute patients when compared with chronic patients.
Conclusion: Meniscal repair improves outcomes for recent vascular longitudinal tears, with factors like tear length and pattern influencing outcomes. The outside-in technique with vertical sutures is minimally invasive, simple, and cost-effective.
