OBJECTIVES
To explore the gender differences in the concomitant articular injuries after acute lateral patellar dislocation (LPD).
METHODS
Magnetic resonance images were prospectively analyzed in 166 patients after an acute LPD. Concomitant articular injuries included bone contusion, medial patellofemoral ligament (MPFL) injury, articular cartilage lesion, and vastus medialis obliquus (VMO) lesion. Statistical analyses were performed between the patient's gender and the incidence of concomitant articular injuries in adolescent and adult subgroups.
RESULTS
The incidence of partial and complete MPFL tear in adolescent males and females were (45%, 50%) and (63.2%, 29.8%), respectively. Compared with adolescent females, adolescent males showed higher incidence of complete MPFL tear (P = 0.049). The incidence of articular cartilage lesion of patella in adolescent males and females were 40% and 21.1%, respectively. Compared with adolescent females, adolescent males showed higher incidence of articular cartilage lesion of the patella (P = 0.043). No correlations were identified in other injuries in the adolescent group. The incidence of partial and complete MPFL tear in adult males and females were (34.4%, 65.6%) and (56.8%, 37.8%), respectively. Compared with adult females, adult males showed higher incidence of complete MPFL tear (P = 0.036). The incidence of articular cartilage lesion of patella in adult males and females were 56.3% and 32.4%, respectively. Compared with adult females, adult males showed higher incidence of articular cartilage lesion of patella (P = 0.047). The incidence of VMO injury in adult males and females were 59.4% and 35.1%, respectively. Compared with adult females, adult males showed higher incidence of VMO injury (P = 0.044). No correlations were identified in other injuries in the adult group.
CONCLUSIONS
Compared with females, males predispose to complete MPFL tear and articular cartilage lesion of patella after acute LPD. Compared with female adults, male adults predispose to VMO injury.
目的
探讨急性外侧髌骨脱位（LPD）后伴发关节损伤的性别差异。
方法
前瞻性分析 166 例急性 LPD 患者的磁共振成像结果。伴发关节损伤包括骨挫伤、内侧髌股韧带（MPFL）损伤、关节软骨损伤和股四头肌内侧斜肌（VMO）损伤。对青少年亚组和成年亚组中患者性别与伴发关节损伤发生率之间进行统计学分析。
结果
青少年男性和女性中部分和完全 MPFL 撕裂的发生率分别为（45%，50%）和（63.2%，29.8%）。与青少年女性相比，青少年男性完全 MPFL 撕裂的发生率更高（P=0.049）。青少年男性和女性髌骨关节软骨损伤的发生率分别为 40%和 21.1%。与青少年女性相比，青少年男性髌骨关节软骨损伤的发生率更高（P=0.043）。在青少年组中，其他损伤未见相关性。成年男性和女性中部分和完全 MPFL 撕裂的发生率分别为（34.4%，65.6%）和（56.8%，37.8%）。与成年女性相比，成年男性完全 MPFL 撕裂的发生率更高（P=0.036）。成年男性和女性髌骨关节软骨损伤的发生率分别为 56.3%和 32.4%。与成年女性相比，成年男性髌骨关节软骨损伤的发生率更高（P=0.047）。成年男性和女性 VMO 损伤的发生率分别为 59.4%和 35.1%。与成年女性相比，成年男性 VMO 损伤的发生率更高（P=0.044）。在成年组中，其他损伤未见相关性。
结论
与女性相比，男性在急性 LPD 后更易发生完全 MPFL 撕裂和髌骨关节软骨损伤。与成年女性相比，成年男性更易发生 VMO 损伤。
