Active clinical trials for "Tibial Meniscus Injuries"

This study is a post-market follow-up study. The data collected from this study will serve the purpose of confirming the safety and performance of the JuggerStitch Device used for meniscal repair according to the product labelling (Instruction For Use).

Comparison of intra-articular administration of synovial fluid-derived mesenchymal stem cells-derived exosomes with synovial fluid-derived mesenchymal stem cells on the same patient.

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.

The purpose of this study is to evaluate post-operative outcomes after meniscus surgery in participants undergoing blood flow restriction training as a rehabilitative adjunct compared to those with standard rehabilitation.

The purpose of this study is to determine differences in pain, functional patient reported outcomes, and objective imaging parameters following non-operative and meniscus root repair treatment. Furthermore, the long-term goal of this research proposal is to understand the natural history of meniscal root tears and their subsequent repair, in order to better determine risk factors for inferior outcomes and progression to osteoarthritis (OA).

This observational study will compare the clinical value of weight-bearing CT arthrography (WBCTa) with that for MRI in evaluating meniscal and cartilage lesions of the knee joint. The MRI Osteoarthritis Knee Score (MOAKS) and modified MOAKS for WBCTa will be used to compare findings between MRI and WBCTa of the knee while comparing with surgical measurements using the ICRS scoring system. The study hypothesis is that meniscal and cartilage lesions may be missed by non-weight-bearing MRI, but detected by WBCTa.

The purpose of this study is to determine if extended-release triamcinolone acetonide treatment alters the progressive changes in bone shape previously demonstrated after anterior cruciate ligament (ACL) reconstruction with partial meniscectomy or meniscal repair.

The menisci of the knee are essential fibro-cartilaginous structures that contribute in static weight bearing, distributing compressive forces during joint movement, joint lubrication, joint stabilization, and proprioception. The menisci are commonly torn, interfering with these vital functions, with an estimated mean annual incidence as high as 60-70 per 100,000 knee injuries. When torn, the odds of developing future osteoarthritis within 2 years of follow-up can be as high as 5.92. The management of meniscal tears remains a challenge given the poor intrinsic healing capacity of tears occurring in the inner, avascular, portion of the meniscus where direct surgical repair techniques are commonly unsuccessful. Autologous adipose tissue injection has recently emerged as a promising new treatment for joint pain and soft tissue injury. Adipose can be used to provide cushioning and filling of structural defects and has been shown to have an abundance of bioactive elements and regenerative perivascular cells (pericytes).The aim of this study is to explore the potential of Lipogems® micro-fragmented adipose tissue as a meaningful treatment option for meniscus tears. Patients treated with MFAT with intra-meniscal injections under continuous ultrasound guidance are expected to report clinically meaningful improvements in knee pain and knee function after one year. Knee pain and function will be measured using a numerical pain scale (NPS) and the Knee Injury and Osteoarthritis Outcome Scale (KOOS).

After a cartilage or meniscus repair in the knee joint, the patients experience a pronounced and persistent decrease of knee-extension strength in the operated leg, which negatively affect patients' functional performance and quality of life. A possible novel exercise modality to increase muscle strength early is a moderate blood flow restriction with low-load strength training (BFR-LLST) exercise. BFR-LLST involves application of a wrapping device to restrict the blood flow to the muscle(s) during exercise. BFR- LLST requires much less load than traditional strength training and has shown to produce positive training adaptations such as muscle hypertrophy and strength in the lower extremity in healthy subjects and patients with a knee surgery. To our knowledge, early rehabilitation with BFR-LLST has never been investigated in a population with weight bearing restrictions, such as patients recovering from cartilage or meniscus repair in the knee joint. Fear of symptom exacerbation and adverse events have precluded BFR-LLST early after knee surgery. The purpose of this study is to examine the feasibility of 9 weeks of supervised rehabilitation with BFR-LLST early after cartilage or meniscus repair in the knee joint.

The utilization of arthroscopic surgery to treat meniscus injuries has continued to increase in recent years, partly due to a younger, more active population, and improved technology and technique. However, pain management in the post-operative period is critical to the ability to perform this procedure as an outpatient surgery. Traditionally, oral narcotic agents have been the preferred analgesic postoperatively in orthopaedic surgery. However, these agents are associated with several side effects, including nausea/vomiting, constipation, and somnolence. In addition, opioid agents have a significant potential for abuse in comparison to non-narcotic analgesics. In light of the rising opioid epidemic and nationwide initiatives to limit narcotic usage, surgeons must explore alternate pain modalities in the acute postoperative period. Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) with analgesic and anti-inflammatory properties.1 Multiple prior studies have examined the beneficial effect of oral and intravenous (IV) ketorolac as an analgesic in the postoperative period,1-3 including arthroscopic meniscus surgery. However, the beneficial effects of this agent following arthroscopic meniscus surgery have not been extensively described.
