Osteoarthrosis knee: Need for a simplified prognostic knee score

Abstract

Osteoarthrosis is the commonest joint disorder. There may be variations depending upon the type of joint involved and amount of loading of joint. Weight bearing joints appears to have a higher predisposition as compared to other joints. The treatment modalities for symptom relief vary from nonpharmacological to pharmacological and surgical interventions. The type of intervention required depends mainly on the amount of joint destruction which can be quantified clinically and radiologically. Knee joint is one of most common joints affected in destructive pathology and taken for the most invasive procedure i.e joint replacement. Treatment choice is based on clinical evaluation,radiological changes and patient specific scores. Osteoarthritis of knee can be primary or secondary and symptoms complex can be quantified using various scales like WOMAC, HSS, KOOS, OKS and KSS. The radiological criteria of Kellgren and Lawrence can be applied to assess the extent of destruction. The two extremes of all criteria explains the normal and worst conditions. No criteria explains the amount or the type of intervention needed for a particular stage of disease. All criteria being nonuniform and diverse. The other most important thing being difficult utility and tredious scoring system. The present need is a single, easy,clinically validated scoring system which combines clinical,radiological and patient reported variables which can guide treatment interventions and has the ability to prognosticate the disease. New score (KALIA AND RAINA Score) can be recognised as a new assessment tool in evaluating a patient for osteoarthrosis knee in future.
