Ultrasound-Guided Injections for Meniscal Injuries in Active-Duty Military

• Status: Recruiting
• Trial end date: 2022-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Knee injuries are common among active-duty military personnel. One of the most common knee injuries is a meniscus tear, which can have several consequences. Immediately, the soldier may be separated from the military for over one year or assigned a permanent activity limiting duty profile. Over time, meniscal tears may also increase the risk of other knee injuries, such as osteoarthritis, which is one of the most common medical reasons for discharge from active duty service. The current standard of care includes conservative treatments, such as physical therapy and rest. Once conservative treatments fail, surgery is generally the next option. However, there is limited evidence that surgery is effective and some studies suggest it can accelerate the development of osteoarthritis. The goal of this study is to evaluate the efficacy of a regenerative treatment for meniscal tears termed micro-fragmented adipose tissue in reducing pain and restoring activity levels. We will recruit active-duty military personnel and civilians with meniscal tears and provide them with either the adipose tissue treatment or a control treatment consisting of saline. We will then follow these individuals for up to one year and evaluate differences in pain and function between the two groups. The ultimate goal is to show that micro-fragmented adipose tissue is a viable alternative for the treatment of meniscal tears in active-duty military personnel.

Criteria

Inclusion Criteria:

• 18-45 years old.

• At least one of the following symptoms consistent with torn meniscus: joint line pain, clicking, popping, pain with pivot or torque.

• Physical examination findings consistent with a meniscal tear: joint line tenderness; localized pain with flexion; and other provocative tests such as McMurray's and Thessaly test.

• MRI or arthroscopic evidence of meniscal tear without significant additional joint pathology.

• Failed conservative treatment for a minimum of 4 weeks, which has included rest, ice, anti-inflammatory or other medications for pain; physical therapy; with or without/ injections, including corticosteroid and/or hyaluronic acid injections.

Additional criteria: Patients who have been told by an orthopedic surgeon that they would be a candidate for arthroscopic partial meniscectomy.

Exclusion Criteria:

• Chronically locked knee.

• Greater than Kellgren-Lawrence Grade II.

• Prior surgery performed on the effected knee.

• Assessment showing anything other than degenerative tears of the medial meniscus requiring surgical intervention.

• Recent (within 6 weeks) treatment with PRP, cortisone (oral or injection), or hyaluronic injection.

• Any disease or condition the investigator feels would hinder treatment.

• Any contra-indication to lipoaspirate, including a bleeding disorder, infection, pregnancy, or allergy to anesthetic agents.

• Chronic inflammatory diseases such as rheumatoid arthritis.

• Possible joint infection including Lyme disease of the joint.

• Malignancy within the last 5 years.
