The purpose of this study is to review seven years of medical experience with injuries to players of a profes sional basketball club. One of the authors was in volved with all injuries occurring during this period of time. All 71 athletes participating with this club were evaluated, and their specific injuries were studied with regard to incidence, time loss due to injury, and treat ment. Foot, ankle, knee, back, and hand injuries were found to occur most often. The most common as well as the most severe injuries were those of the ankle and knee. The average time loss from play due to injury was amazingly consistent for each specific in jury. Rehabilitation of injuries varied from no playing time loss to two years. Even though knee injuries carry a poor prognosis, the authors conclude that the inci dence of severe injury in professional basketball is low. This study will hopefully serve as useful informa tion for those involved with the care of basketball players.
