Background: The incidence of Achilles ruptures has been on the rise in National Collegiate Athletic Association (NCAA) football players, but the career impact of this injury is not fully understood. In this study, we analyzed a large series of Achilles tendon injuries in NCAA Football Bowl Subdivision (FBS) defensive football players who required repair in order to determine their return to play, performance, and career outcomes afterward. Methods: FBS defensive football players who required Achilles repair from 2010 to 2016 were identified. The return to play of the eligible underclassmen athletes was then determined and the preinjury and postoperative performances of players who met criteria were compared with matched controls. The number of underclassmen who went on to participate in the National Football League (NFL) Combine or play in at least 1 NFL game was also determined and compared with controls. Results: Fifty-seven total Achilles ruptures were identified, 40 of which occurred in underclassmen, who returned at a rate of 92.5%. Of the players who met performance criteria, only defensive backs differed from matched controls in terms of solo tackling ( P = .025) and total tackling (P = .038), while still increasing compared with preoperative performance. Only 5.0% of underclassmen performed at NFL Combine and only 7.5% competed in at least 1 NFL game (20.0% and 21.3%, respectively, for matched controls). Conclusion: Defensive FBS players returned at a high rate following Achilles rupture and did not seem to experience a significant drop-off in performance upon return. An Achilles rupture did appear to impact their chances of playing professionally in the future, however. Level of Evidence: Level III, retrospective comparative study.

Background. First metatarsophalangeal (MTP) arthrodesis is the “gold standard” treatment for hallux rigidus. Recently, there has been increased interest in new synthetic cartilage implants to preserve joint motion while eradicating pain. With current health care economics, the cost of a treatment is gaining particular importance. This study set out to perform a cost comparison between MTP arthrodesis and synthetic hydrogel implant to determine which treatment modality is more cost-effective based on direct aggregate costs. Study design. Economic and decision analysis. Methods. Studies in the available literature were analyzed to estimate hardware removal rates for MTP fusion and failure rates for a synthetic hydrogel implant and MTP fusion. Costs were determined by examining direct costs at a single institution for implants and data reported in the literature for operating room time. Sensitivity analysis and Monte Carlo simulation were performed to examine cost and measurement uncertainty. Results. Assuming a 4.76% MTP arthrodesis revision rate and 7.06% hardware removal rate, the total direct cost of MTP joint arthrodesis was $3632. Using a 9.2% failure rate with subsequent conversion to MTP arthrodesis, the total cost of synthetic hydrogel implant was $4565. Sensitivity analysis revealed that MTP fusion was more cost-effective even if the failure rate increased to 15% and synthetic hydrogel implant failure rate was 0%. The synthetic cartilage implant cost would have to be reduced 28% or approximately 200% the cost of MTP fusion implants to be comparable to MTP arthrodesis. Conclusion. Hallux rigidus treatment with a synthetic hydrogel implant resulted in a higher direct aggregate cost than MTP arthrodesis. Level of Evidence: Level II: Cost analysis
