Traumatic or degenerative meniscal lesions are a frequent problem. The meniscus cannot regenerate after resection. These lesions often progress and lead to osteoarthritis. Collagen meniscal implants have been used in clinical practice to regenerate... 

Fig. 21.19 (a) Model of a semi-circular cartilaginous disk (Meniscus) that resides in the knee joint, (b) Molded bacterial cellulose meniscus, (c) Implantation of the construct into a created meniscal lesion in vivo. The traction sutures are visible on the outer third of the meniscus. The seeded implant (Arrow 1) is inserted into the created meniscal lesion with an Adson forcep. The insertion of the implant is facilitated by the use of a hemostat, opening the lesion (arrow 2)...

In cases of isolated meniscus lesion, there is a lack of evidence to support the theory that repair of the meniscus prevents progression of osteoarthritis [22, 59]. However, concomitant ACL reconstruction is usually described as one of the most favorable factors of successful meniscal repair. Several studies [15, 60, 61] showed a high success rate of meniscal repair with concurrent ACL...

Radiographs can identify associated avulsion injuries, such as Pelegrini-Stieda lesions (avulsion of the medial femoral condyle at the origin of the medial collateral ligament) and Segond lesion (avulsion fracture of the lateral tihial plateau). Segond fractures are associated with LCL, ACL and meniscal tears (Sferopoulos et al. 2006). 

Meniscal cysts are parameniscal lesions filled with thick mucoid fluid that are usually secondary to degenerative meniscal tears. They affect more commonly the lateral meniscus and the right knee and are associated with horizontal or oblique cleavage meniscal tears. From the pathomechanical standpoint, the synovial fluid enters the meniscal body and produces a small intrameniscal cyst. Fluid... 

Meniscal ossicles are rounded bodies embedded within a meniscal horn, the posterior horn of the medial meniscus being the most commonly affected. These rare lesions, which consist of a peripheral bony...
