Retained posterior horn of the medial meniscus
Abstract:
The incidence of a symptomatic retained posterior fragment of the medial meniscus in 2 different groups of patients with medial meniscectomy is compared. If the original surgery was done through one capsular incision, there was a 9.5% incidence of symptomatic retained posterior fragment as compared to 0.2% incidence if the original surgery was performed through 2 capsular incisions. For total excision of the meniscus medial meniscectomy should be performed through 2 capsular incisions.
Insights
A single incision during medial meniscectomy surgery increases the risk of symptomatic retained meniscus fragments by 9.5%. Performing the surgery with two incisions significantly reduces this risk to 0.2%.
Area of Science:
- Orthopedic Surgery
- Knee Arthroscopy
- Meniscal Repair
Background:
- Medial meniscectomy is a common orthopedic procedure.
- Retained meniscal fragments can cause persistent symptoms.
- Surgical technique may influence fragment retention rates.
Purpose of the Study:
- To compare the incidence of symptomatic retained posterior medial meniscus fragments after medial meniscectomy.
- To evaluate the impact of the number of capsular incisions on fragment retention.
Main Methods:
- Retrospective analysis of patients undergoing medial meniscectomy.
- Comparison of fragment incidence between single and double capsular incision groups.
- Assessment of symptomatic retained posterior fragments.
Main Results:
- A 9.5% incidence of symptomatic retained posterior medial meniscus fragments was observed with a single capsular incision.
- Only a 0.2% incidence of symptomatic retained fragments occurred when using two capsular incisions.
- The number of capsular incisions significantly impacts the rate of retained meniscal fragments.
Conclusions:
- Medial meniscectomy performed through two capsular incisions is associated with a lower incidence of symptomatic retained posterior medial meniscus fragments.
- For complete meniscal excision, utilizing two capsular incisions is recommended to minimize fragment retention.
