Shoaib recently underwent a successful surgery by noted knee and sports injuries specialist Dr David Young in Melbourne to remove floating pieces of cartilage and drain excess fluid from the knees.
He said he will return home on Friday from Australia after doctors completed a successful surgery on his injured knees.
''I have started slowly walking again and I shall return home by Friday. I am feeling comfortable after the operations which the doctors say have been good for me but they have asked me to follow a strict exercise regimen in my rehabilitation process,'' Shoaib was quoted as saying from Melbourne by The News today.
''It is good that my problem has been diagnosed so early as now I have considerable time to recover for the England tour in late June,'' the fast bowler, who had taken 165 Test and 199 ODI wickets, added.
