Mensicus is a cushion in the knee between your thigh bone and your shin bone. There are two of them in each knee and can get damaged or torn during activities. For years the only procedure done to repair or manage this damaged/torn cartilage was arthoscopy, but as evidence started surfacing over the years, it has become quiet clear that arthoscopic surgeries where pieces of knee meniscus are cut out, is not helpful for the patients and can be more harmful in the long run.
The Evidence
The concept for meniscus damage surgery was straight forward- clean up the tissue which is damaged like you clean up your table after a big lunch at the office. It came under question as early as 2002 when a highly rated journal New England Journal of medicine https://www.nejm.org/doi/full/10.1056/NEJMoa013259 started doubting its long term benefits. Another recent article in same journal shows that arthoscopic surgery for knee osteroarthritis provides no additional benefit to optomized physical and medical therapy (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6289903/pdf/main.pdf)
Arthroscopic knee surgery again came under review with yet one more article in New England Journal (https://www.nejm.org/doi/full/10.1056/NEJMoa0800777) which stated that upto 60% of people who had meniscus tears on their MRI actually suffered from no knee pain, of those with arthritis and knee pain, 63% had meniscal tears. The math is pretty clear that most of patients end up getting an unnecessary arthroscopic knee surgery to repair the painless tear that could have multiple of non-surgical causes for their pain and land up in early arthritis .
Joint Preservation and Regenerative medicine
The above confusion of meniscal and arthritis management can be easily avoided, if evaluated from a perspective of joint preservation and regenerative medicine point of view. In this, the knee joint is looked into as a whole unit including muscles, ligaments, joints and pain triggers are first smoothened out before going ahead with Prp and bone marrow concentrate procedures.
