Hello,
In Moderate Knee Osteoarthritis(OA) visco supplement/gel injection might give temporary relief. The duration of effect varies person to person depending on various other factors. In some patients it might last for few months and in some for a year or more.
For better results you have to adapt some lifestyle modification such as avoid sitting cross legged, avoid squatting, avoid/restrict climbing stairs, use western commode, weight reduction(if over weight). These lifestyle modifications go hand in hand with any treatment modality of OA KNEE.
Along with this appropriate physiotherapy exercise (as advised by an orthopaedic doctor and supervised by qualified physiotherapist) play a major role.
Ice fomentation will also help to reduce pain and swelling
Side effects such as injection site pain and swelling, rarely infection or allergic reaction may be seen in some patients.
(Note: This opinion is based on the assumption that an qualification orthopaedician has reached to the said diagnosis and staging mentioned in the query)
