Despite the great evolvement of sports medicine, there is still a lack of consensus among sports physicians regarding the decision of return to sports after knee injury, especially in non-elite sports. Currently, no sport-specific reference data for an objective reliable evaluation of functional knee stability exist. The purpose of this study was to assess objective measures on knee joint stability from an established test battery in non-elite handball. It was assumed that players' knee stability differs depending on their field position.
One-hundred and sixty-five non-elite handball players with a mean age of 24.3 ± 5.5 years underwent a test battery including two-legged and one-legged stability tests, two-legged and one-legged counter movement jumps, two-legged plyometric jumps, one-legged speedy jumps, and a quick feed test.
Athletes' physical performance differs in terms of field position. Significant differences between handball players of different positions were found in regard to two-legged stability (p < 0.036) and one-legged stability in the dominant leg (p < 0.009). Players of different positions differed in ground contact time of the plyometric jumps (p < 0.017), whereas the other functional tests did not show significant differences.
This study is first to report differences in functional knee stability of non-elite handball players on the basis of objective data. Significant differences of functional performance were noted, which were in congruence with position-specific demands. These findings demonstrate the importance of position-specific screening and training to prevent injuries.

尽管运动医学有了很大的发展，但运动医学医生在膝关节损伤后重返运动的决策上仍缺乏共识，尤其是在非精英运动中。目前，还没有针对特定运动的参考数据来客观可靠地评估膝关节稳定性。本研究的目的是评估非精英手球中从已建立的测试组合中得出的膝关节稳定性的客观指标。假设球员的膝关节稳定性因场上位置而异。
165 名平均年龄为 24.3±5.5 岁的非精英手球运动员接受了一项测试组合，包括双腿和单腿稳定性测试、双腿和单腿反向运动跳跃、双腿增强式跳跃、单腿快速跳跃和快速传球测试。
运动员的身体表现因场上位置而异。不同位置的手球运动员在双腿稳定性（p<0.036）和优势腿单腿稳定性（p<0.009）方面存在显著差异。不同位置的运动员在增强式跳跃的触地时间（p<0.017）方面存在差异，而其他功能测试则没有显示出显著差异。
本研究首次基于客观数据报告了非精英手球运动员膝关节稳定性的差异。功能性表现存在显著差异，与特定位置的需求一致。这些发现表明，针对特定位置的筛查和训练对于预防受伤至关重要。
