The knee joint is often twisted and uncomfortable like a misalignment. It may be a meniscus lock after a meniscus injury. It is also possible that the cruciate ligament of the knee joint is torn and the knee joint is unstable. If a meniscus or cruciate ligament problem is considered, an MRI of the knee can be completed to determine the cause more accurately. For more severe meniscal damage, arthroscopic meniscal suturing or partial resection can be performed. If the knee is unstable due to a ruptured cruciate ligament, arthroscopic reconstructive knee surgery can be considered to restore the stability of the knee joint, which can help to significantly improve such a phenomenon.
