Answer by taking a quote from the following article:

Bjorn Borg was born in Stockholm, Sweden, on 6 June 1956, as the only child of Rune and Margaretha Borg. He grew up in nearby Sodertalje. As a child, Borg became fascinated with a golden tennis racket that his father won at a table-tennis tournament. His father gave him the racket, beginning his tennis career.

Borg had one of the most distinctive playing styles in the Open Era. He played from the baseline, with powerful ground-strokes. His highly unorthodox backhand involved taking his racket back with both hands but actually generating his power with his dominant right hand, letting go of the grip with his left hand around point of contact, and following through with his swing as a one-hander. He hit the ball hard and high from the back of the court and brought it down with considerable topspin, which made his ground strokes very consistent. There had been other players, particularly Rod Laver and Arthur Ashe, who played with topspin on both the forehand and backhand, yet Laver and Ashe used topspin only as a way to mix up their shots to pass their opponents at the net easily. Borg was one of the first top players to use heavy topspin on his shots consistently.  Complementing his consistent ground-strokes was his fitness. Both of these factors allowed Borg to be dominant at the French Open.  One of the factors that made Borg unique was his dominance on the grass courts of Wimbledon, where baseliners since World War II did not usually succeed. Some experts attributed his dominance on this surface to his consistency, an underrated serve, equally underrated volleys, and his adaptation to grass courts. Against the best players, he almost always served-and-volleyed on his first serves (but he naturally played from the baseline after his second serves).  Another trait usually associated with Borg is his grace under pressure. His calm court demeanor earned him the nickname of the "Ice Man" or "Ice-Borg."  Borg's physical conditioning was legendary and unrivalled. He could outlast most of his opponents under the most grueling conditions. Contrary to popular belief, however, this wasn't due to his exceptionally low resting heart rate, often reported to be near 35 beats per minute. In his introduction to Borg's autobiography My Life and Game, Eugene Scott relates that this rumor arose from a medical exam the 18-year-old Borg once took for military service, where his pulse was recorded as 38. Scott goes on to reveal Borg's true pulse rate as "about 50 when he wakes up and around 60 in the afternoon." Borg is credited with helping to develop the style of play that has come to dominate the game today.

Did his style cause him physical injuries?
