how did ronaldo injured his knee when playing for inter

Ronaldo Nazário injured his knee at Inter during a match against Lecce in November 1999, when he ruptured a tendon in his right knee. He later re- injured it badly on April 12, 2000, during the Coppa Italia final first leg against Lazio , when the patellar tendon in the same knee completely gave way.

What happened

• The first injury came in a league game against Lecce, and it sidelined him for months.

• When he returned in April 2000 against Lazio, the knee collapsed again just minutes into his comeback.

• Reports describe it as a catastrophic tendon rupture, not a simple knock or twist.

Why people still talk about it

The second injury was viewed as career-defining because it happened right after his comeback and kept him from playing at full capacity for a long stretch afterward.

Short version

He first hurt the knee against Lecce, then suffered a much worse rupture on his return against Lazio, which is the injury most people remember from his Inter years.

TL;DR: Ronaldo’s Inter knee problems started with a tendon rupture against Lecce and escalated into a major patellar tendon tear against Lazio in April 2000.
