Giannis Antetokounmpo, star forward for the Milwaukee Bucks, has had his share of injuries over the years. When fans ask what did Giannis injure, the answer depends on which injury and which timeline you refer to. He has injured different parts of his body-knees, calf muscles, foot, shoulder-at various points. Some were minor and temporary, others more serious and requiring rest or altered play. Below, we explore the most notable injuries Giannis has sustained, what they involved, and how they impacted his performance and recovery.
Major Knee Hyperextension in 2021 Playoffs
One of the most dramatic injuries in Giannis’s career occurred during the 2021 Eastern Conference Finals against the Atlanta Hawks. In Game 4, he landed awkwardly and hyperextended his left knee. Initially, there was concern about torn ligaments, but medical scans later revealed that while he didn’t suffer a tear, the hyperextension forced him out of the remainder of that game and sidelined him for subsequent games in the series.
That injury was a clear reminder of how even elite athletes can be vulnerable to joint trauma under intense pressure. Although it did not lead to catastrophic structural damage, it required rest and precaution as the Bucks pushed onward to win the series without him.
Recent 2024-25 Season Injuries
In the 2024-25 season, Giannis has faced several injury issues that affected his availability across games. These include calf strain, foot sprain, patella (knee) tendinopathy, and shoulder issues. Many of these were listed in official injury reports, and some incurred missed games.
Left Calf Strain
In early February 2025, the Bucks announced that Giannis would be out for at least a week due to a left calf strain. He had already missed several games, and this injury was serious enough to keep him out of the All-Star Game. The injury recurred as a lower-body concern that the team monitored carefully, especially given his physical style of play.
Foot Sprain
Later in the season, Giannis was listed as questionable due to a foot sprain. This affected his availability for matchups such as the game against the New York Knicks, where he was designated as game time decision. Foot sprains are tricky for high-impact athletes, since they affect stability and mobility-crucial qualities for Giannis’s style.
Right Knee / Patella Tendinopathy
In February 2025, the Bucks ruled Giannis out of a game against the Oklahoma City Thunder due to a right knee issue-specifically patella tendinopathy. Patella tendinopathy is an overuse injury of the tendon connecting the kneecap to the shinbone, often causing pain during jumping and running. This type of injury can flare up under heavy workloads, so rest and careful load management are essential parts of recovery.
Left Shoulder Tendinopathy
Giannis was also listed as doubtful at times due to left shoulder tendinopathy. The shoulder is less frequently injured in his case compared to lower-body problems, but it matters for rebounding, passing, and physical contact. This shoulder condition appeared in reports prior to games, sometimes restricting his full motion or making him more cautious in certain movements.
Other Past Injuries
Giannis’s injury history extends beyond these recent issues. Earlier seasons saw strains, knee soreness, and occasional minor injuries. According to compilations of injury logs, he has had hamstring issues, Achilles concerns, and other knee or leg complaints. These injuries were usually managed and did not require long-term absence, but they underscore how a high-level basketball career involves constant wear and tear.
Impact and Recovery Considerations
The common thread among Giannis’s injuries is that they tend to affect his lower body-calves, knees, feet-areas that endure a lot of stress in basketball. Recovery and prevention, therefore, focus on
- Rest and load management, allowing healing and avoiding re-injury
- Physical therapy targeting strength, flexibility, and tendon resilience
- Monitoring workload, especially in back-to-back games or extended minutes
- Proper warm-up, conditioning, and recovery protocols
Teams often hold players out during noncritical games to preserve their health for playoffs, something the Bucks have done with Giannis when managing calf or knee issues.
So, what did Giannis injure? Over his career he has sustained injuries to his knee (notably the hyperextension in 2021), calf strains, foot sprains, patella tendinopathy in the knee, and shoulder tendinopathy. While none of these setbacks have derailed his career permanently, they have required caution, rest, and adjustment. For a player of his physical style, keeping those joints and tendons healthy is a continuous challenge. As of the 2024-25 season, the most recent injuries-left calf strain, foot sprain, right knee tendinopathy, and left shoulder tendinopathy-are the ones most relevant to fans wondering what Giannis has injured now.
