The 1985–1988 stretch of a heavy playing schedule, and lack of rest, took a significant toll on Sabonis' future health and durability. Various leg injuries were not given much time to heal, due to the Cold War climate that surrounded international competition, as well as the intense rivalry of the Žalgiris Kaunas versus CSKA Moscow games in the USSR Premier League. In a 2011 interview, Sabonis expressed an opinion, that overuse by the coaches of the Soviet national program, was a major contributing factor to his first Achilles' tendon injury, back in 1986. Another key moment for his future health, took place in 1988, when Sabonis had a surgical Achilles procedure performed in Portland, but was rushed back on the floor with the USSR Olympic team, before a full recovery. The decision to include a limping Sabonis, on the USSR roster for the 1988 Olympic Games, was protested at the time by the Portland medical staff, and was later heavily criticized. While the Soviets cleared him to play professionally in 1989, when his Soviet national teammate, Šarūnas Marčiulionis, went to North America, Sabonis postponed his travel, over feeling that he was not physically ready for the NBA. Eventually, Sabonis would develop chronic knee, ankle and groin issues, that substantially limited his mobility and explosiveness, by the mid-1990s.
