To compare the wound healing after total knee replacement wound closure with staples versus subcuticular prolene suture.

.Informed consent will be taken from all the patients who meet the inclusion and exclusion criteria and then will be randomized into one of the two study arms (Arm 1: will undergo wound closure with staples and Arm 2 wound closure with subcuticular prolene suture).

before the start of surgery. The primary investigator will open the sealed envelopes provided by the Indus Hospital Research Center's Clinical Research Unit (CRU) that provides the study arm allocation. The envelopes will follow the SNOSE protocol i.e. they will be sequentially numbered, opaque sealed envelopes. Before opening the envelope, the primary investigator will write the patient's medical record number, date and will sign the envelope. The envelope will contain carbon paper which will transfer the data allocation paper inside.
