Case: We report a case of a right knee lateral bucket-handle meniscal tear repair in a 25-year-old woman bilateral below-knee amputee. At the 4-year follow-up, the patient was ambulatory in a prosthesis with a successful outcome.
Conclusion: Meniscus repair in below-knee amputees requires careful evaluation and surgical management. Specific consideration should be given to evaluating limb alignment, maintaining the stump integrity, surgical technique, modified bracing, and rehabilitation. This case report demonstrates that bucket-handle meniscus repair can be successful in a below-knee amputee.

Background: Meniscal injuries that fail to heal instigate catabolic changes in the knee's microenvironment, posing a high risk for developing posttraumatic osteoarthritis (PTOA). Previous research has suggested that human cartilage-derived progenitor cells (hCPCs) can stimulate meniscal repair in a manner that depends on stromal cell-derived factor 1 (SDF-1) pathway activity.
Hypothesis: Overexpressing the SDF-1 receptor CXCR4 in hCPCs will increase cell trafficking and further improve the repair efficacy of meniscal injuries.

Medial meniscus root tears (MMRTs) are serious injuries that disrupt knee biomechanics, often accelerating cartilage degeneration and osteoarthritis when left untreated. These injuries are increasingly recognized as a major cause of knee pain and functional limitations, particularly among middle-aged and older adults. This systematic review and meta-analysis aimed to evaluate the outcomes of conservative management compared to surgical intervention for MMRT, focusing on pain relief, functional recovery, and the progression of osteoarthritis.

Osteochondritis dissecans is a rare condition characterized by the deterioration of a small area of bone and cartilage without infection. Its exact cause is unclear, though factors such as abnormal bone development, joint pressure, repetitive injuries, inadequate blood supply, and genetic links have been observed. In this case, a 27-year-old woman experienced chronic right knee pain following a twisting injury, which led to reduced mobility and mild pain.

Tears of the posterior medial meniscus root (PMMR) are common in older patients and reportedly contribute to rapid joint degeneration over time. Recognition of these tear types and the appropriate diagnosis through clinical exam and diagnostic imaging have improved significantly in recent years, as have surgical techniques to address them. Standardized post-operative rehabilitation protocols specific to PMMR repair have not been established or well understood in the scientific literature.

In anterior cruciate ligament (ACL) repair methods, the continuous enzymatic erosion of synovial fluid can impede healing and potentially lead to repair failure, as well as exacerbate articular cartilage wear, resulting in joint degeneration. Inspired by the blood clot during medial collateral ligament healing, we developed a composite scaffold comprising collagen (1 %, w/v) and polyvinyl alcohol (5 %, w/v) combined with platelet-rich plasma (PRP). The composite scaffold provides a protective barrier against synovial erosion for the ruptured ACL, while simultaneously facilitating tissue repair, thereby enhancing the efficacy of ACL repair techniques.
