Aidiniou was born on 2 February 1948 in Psarades.[1][2] Although he was a track and field athlete, he was talked into signing for Iraklis by two teachers of him, themselves fans of the club.[1] After joining the youth ranks of Iraklis in 1963, Aidiniou made his first team debut in 1965, scoring against Olympiacos in a 2–1 away defeat of Iraklis.[1][3] Aidiniou was the star player of Iraklis until 1974, when he signed for Olympiacos for 11,000,000 drachmas.[4][5]
Aidiniou could not compete for the 1974–75 season as his transfer was considered overdue.[3] For the whole season he only contested in friendly matches and training courses and that humped his adaptation to his new club.[3] In Olympiacos Aidiniou failed to demonstrate the same level of football as he did in Iraklis and he was released from Olympiacos after the 1977–78 season.[3][4] Aidiniou appeared in a total of 40 league matches for Olympiacos, scoring 7 goals.[1][3][4]
Aidiniou returned to Iraklis for the 1978–79 season appearing in 13 matches and failing to score any goals.[6] He retired after that season, aged 31.[1] In his two spells with Iraklis Aidiniou totalled 232 appearances and 57 goals.[1]
Aidiniou scored in his debut for Greece in a 4–1 win against Egypt in Athens.[7] His last match for Greece came on 15 May 1974, under Alketas Panagoulias, in a friendly match against Poland.[8] Aidiniou appeared in seven matches of Greece, managing to score three goals.[9]
Aidiniou had a stint as Iraklis' manager together with Giorgos Koudas in 1987.[4][10] He has also held several positions in the club's technical staff.[4]
Aidiniou wanted to become a doctor, before deciding to stick at football.[1] After retiring from football he was involved in "Iraklis Former Footballer's Club" becoming its president.[1][11]
