Mulberry Knot Technique for Arthroscopic Meniscus Repair

Abstract

Background: Meniscus treatment varies on factors such as age of the patient, cause of injury, time since injury, clinical features, site of torn meniscus and financial capacity. The treatment ranges from conservative in form of visco supplements, analgesics and physiotherapy to surgery in form of open or arthroscopic repair or partial menisectomy. We aim to show ten cases of arthroscopic meniscus repair using mulberry knot technique. Material And Methods: Meniscus tear was reduced using probe and long spinal needle. Conventional instruments used were meniscus repair set which includes needle and dart sheath with canula. The repair was done using 2-0 prolene with mulberry knot. Observation And Results: The average follow up period in our study was 3±1.2 months. As per knee society score, we have achieved 80% excellent and 20% good results at 3 months as shown in table 1. We did not encounter any complication in our study as far as intra operative or post operative events are concerned. Discussion: There are different ways and suturing techniques to repair the meniscus. Mulberry knot provides sliding, stable and secured knot formation which is less bulky and more reliable. It has been used frequently to repair rotator cuff in shoulder arthroscopy. It does not cause post operative impingement during movements in rehabilitation process. Conclusion: Mulberry knot technique is unique, stable, secure knot which is done using Prolene 2-0 to be used for meniscus during arthroscopic procedures outside in and inside out repair techniques.
