Abstract
Osteoarthritis (OA) is the most common degenerative joint disease. Knee OA (KOA) is the most common disability due to pain and dysfunction, it typically affects the medial tibiofemoral joint compartment. The use of orthosis as lateral wedge insoles (LWI) insole help reduction of symptoms and improvement of function, can reduce many of the biomechanical risk factors for disease development in OA patients. The study aims to determine the possible mechanical and clinical effects of the different lateral wedge insoles to assess its role in management of the medial compartment KOA. The study included 48 knees divided into three groups, group A received only conventional physiotherapy, group B received LWI and group C received subtalar strapped (STS) LWI for four months. The Western Ontario and Mcmaster Universities (WOMAC) score showed high significance P˂0.001 for most subscales, femorotibial angle (FTA) and planter pressure peaks at the five metatarsal areas (M1, M2, M3, M4, M5), midfoot (MF), medial and lateral heel areas (MH, LH) and Centre of pressure (COP) showed high significance P˂0.001 for both insoles . The positive outcomes suggested that LWI and STSLWI insert are viable alternative in the conservative management of patients with medial KOA. The use of LWI and STSLWI help to prevent progression of medial KOA if used in early grades of medial KOA as grade 2 and 3. The results not only suggested clinically symptomatic improvement with an inexpensive conservative therapy, but also a less complicated comfortable orthosis of alignment benefit to KOA.
