[Clinical natural development in human meniscus injury]

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Histology

Background:

• Meniscus injuries are common in knee trauma.
• The natural healing process and histological changes of untreated meniscus injuries are not fully understood.

Purpose of the Study:

• To investigate the clinicopathological changes of untreated meniscus injuries.
• To provide a theoretical basis for clinical treatment strategies.

Main Methods:

• 32 patients with meniscus injuries underwent arthroscopy and total meniscectomy.
• Histological analysis of meniscus wound edges using light and electron microscopy.
• Preoperative and postoperative Lysholm scores were used for clinical evaluation.

Main Results:

• Significant improvement in Lysholm scores post-treatment.
• Arthroscopy revealed typical differences in wound edges in 28 cases.
• Microscopic analysis showed cellular changes indicative of attempted healing and atrophy at the wound edges.

Conclusions:

• Untreated meniscus injuries can worsen with activity, leading to increased symptoms.
• Early diagnosis, treatment, and immobilization are vital for meniscus injury healing.
• Total meniscectomy is a satisfactory treatment for irreparable meniscus injuries.
