Brief Summary

Medial meniscus tears requiring surgical interventions are mostly being done by arthroscopic procedures. During the arthroscopy, accessing the medial joint space is challenging. Because of this situation, pie-crusting of the medial collateral ligament (MCL) of the knee is described. This procedure is to release the MCL 1 cm distal to its origin with a needle-tip. This release provides enough space for both identifying the tear and also provides enough space to introduce necessary equipment in the joint space for repair. But there are some doubts about MCL release. Some authors suspected ongoing valgus instability after this procedure. Our aim is to identify the tension of MCL with USG shear wave elastography before the procedure, and 3 weeks, 6 weeks and 3 months postoperatively.

Study Population

Patients with medial meniscal injury

You may qualify if:

• Being 18 years of age or older
• Having a medial meniscus laceration detected in the magnetic resonance imaging taken due to the application for knee complaints and therefore having an indication for surgery
• Having consented to the surgical consent form explaining surgical and non-surgical options, accepting the surgical procedure
• Having consented to the research volunteer consent form presented to him/her verbally and in writing after giving his/her consent for surgery

You may not qualify if:

• Having had a previous fracture, meniscus tear, anterior or posterior cruciate ligament tear, medial or lateral collateral ligament tear in the same or opposite knee.
• Having had arthroscopic or open surgery around the knee due to or outside of the above reasons.
• Having had or not had surgery on the same lower extremity or the opposite lower extremity, having a fracture sequela or deformity.
• Having grade 1 or higher arthrosis according to the Kellgren-Lawrence arthrosis classification on direct radiographs taken before surgery.
• Patients who do not require medial collateral ligament release to access the medial joint space during surgery and therefore do not require pie-crusting medial collateral ligament release.
• Patients who wish to withdraw their consent given to the research volunteer consent form at any time during the study.
