Detail Understanding :-
Osteo-arthritis of knee joint ends with deformed knee joint. A deformity is mall alignment(displacement) of bones causes abnormal position of joints which is irreversible. Two main deformities associated with Osteo-arthritis of knee joint are :-
1) Flexion deformity
Flexion deformity of knee is very common in Osteo-arthritic patients. The main cause is muscle imbalance. The muscles that lies on calf & back of thigh (posterior aspect of leg) become tight & that of on front of leg (anterior aspect of leg) becomes week.
2) Genu Varum (Bow leg)
Genu Varum is a condition where alignment of leg passes through medial compartment rather than center, which leads to increase in stresses on medial compartment of knee.
Both of above two deformities causes abnormal bio mechanics of whole lower limb which further damages the knee. Knee deformities also affect the joints that lie below & above the knee ( i.e ankle joint & hip joint).
