Tarsometatarsal (Lisfranc) joint injuries commonly occur in National Football League (NFL) competition; however, the career effect of these injuries is unknown.
To define the time to return to competition for NFL players who sustained Lisfranc injuries and to quantify the effect on athletic performance.
Case-control study; Level of evidence, 3.
Data on NFL players who sustained a Lisfranc injury between 2000 and 2010 were collected for analysis. Outcomes data included time to return to competition, total games played after season of injury, yearly total yards and touchdowns for offensive players, and yearly total tackles, sacks, and interceptions for defensive players. Offensive power ratings (OPR = [total yards/10] + [total touchdowns × 6]) and defensive power ratings (DPR = total tackles + [total sacks × 2] + [total interceptions × 2]) were calculated for the injury season and for 3 seasons before and after the injury season. Offensive and defensive control groups consisted of all players without an identified Lisfranc injury who competed in the 2005 season.
The study group was composed of 28 NFL athletes who sustained Lisfranc injuries during the study period, including 11 offensive and 17 defensive players. While 2 of 28 (7.1%) players never returned to the NFL, 26 (92.9%) athletes returned to competition at a median of 11.1 (interquartile range [IQR], 10.3-12.5) months from time of injury and missed a median of 8.5 (IQR, 6.3-13.0) regular-season games. Analysis of pre- and postinjury athletic performance revealed no statistically significant changes after return to sport after Lisfranc injury. The magnitude of change in median OPR and DPR observed in offensive and defensive Lisfranc-injured study groups, -34.8 (IQR, -64.4 to 1.4) and -13.5 (-30.9 to 4.3), respectively, was greater than that observed in offensive and defensive control groups, -18.8 (-52.9 to 31.5) and -5.0 (-22.0 to 14.0), respectively; however, these differences did not reach statistical significance (P = .33 and .21, respectively). Evaluation of the durability of injured players after the season of injury revealed no statistically significant difference in career length compared with controls.
More than 90% of NFL athletes who sustained Lisfranc injuries returned to play in the NFL at a median of 11.1 months from time of injury. Offensive and defensive players experienced a decrease in performance after return from injury that did not reach statistical significance compared with their respective control groups over a similar time period.
跗跖(Lisfranc)关节损伤在国家橄榄球联盟(NFL)比赛中较为常见;然而,这些损伤对职业生涯的影响尚不清楚。
确定遭受Lisfranc损伤的NFL球员恢复比赛的时间,并量化对运动表现的影响。
病例对照研究;证据等级,3级。
收集2000年至2010年间遭受Lisfranc损伤的NFL球员的数据进行分析。结果数据包括恢复比赛的时间、受伤赛季后参加的总比赛场次、进攻球员每年的总码数和达阵次数,以及防守球员每年的总擒抱数、擒杀数和抄截数。计算受伤赛季以及受伤赛季前后3个赛季的进攻功率评级(OPR = [总码数/10] + [总达阵次数×6])和防守功率评级(DPR = 总擒抱数 + [总擒杀数×2] + [总抄截数×2])。进攻和防守对照组由2005赛季所有未确诊Lisfranc损伤的参赛球员组成。
研究组由28名在研究期间遭受Lisfranc损伤的NFL运动员组成,包括11名进攻球员和17名防守球员。28名球员中有2名(7.1%)从未重返NFL,26名(92.9%)运动员在受伤后中位数为11.1个月(四分位间距[IQR],10.3 - 12.5)时恢复比赛,平均错过8.5场(IQR,6.3 - 13.0)常规赛。对受伤前后运动表现的分析显示,Lisfranc损伤后恢复运动后,在统计学上没有显著变化。在进攻和防守Lisfranc损伤研究组中观察到的中位数OPR和DPR的变化幅度分别为 - 34.8(IQR, - 64.4至1.4)和 - 13.5( - 30.9至4.3),大于在进攻和防守对照组中观察到的变化幅度,分别为 - 18.8( - 52.9至31.5)和 - 5.0( - 22.0至14.0);然而,这些差异没有达到统计学显著性(P分别为0.33和0.21)。对受伤球员受伤赛季后的耐久性评估显示,与对照组相比,职业生涯长度没有统计学上的显著差异。
超过90%遭受Lisfranc损伤的NFL运动员在受伤后中位数为11.1个月时重返NFL比赛。进攻和防守球员受伤后恢复比赛时,与各自对照组在相似时间段内相比,表现有所下降,但未达到统计学显著性。
