Realignment osteotomies are reliable procedures that have been tried and tested for decades for the treatment of isolated focal cartilage injuries, unicompartmental OA of the femorotibial joint and, in rarer cases, for the femoropatellar joint also. In practice, most realignments osteotomies are performed for the treatment of knee OA with degenerative, poorly defined and extensive cartilage damage. In these cases, unloading of the affected knee joint compartment is the primary surgical procedure and is usually combined with an arthroscopic resection of the meniscus which is almost always also affected and smoothing or debridement of the damaged cartilage areas. For extensive fourth-degree cartilage damage, a careful chondroplasty might be performed, which is not suitable for focal special cartilage restoration procedures. Very good results can be achieved with this combined technique for knees with OA after an appropriate deformity analysis of the leg axis and precise surgery technique. 
Defined, deep-seated cartilage defects should be treated with various cartilage restoration procedures. Also for these cartilage repair techniques the key for successful treatment is the as-sessment of the load-bearing axis of the leg. If there is malalignment causing stress...
