Key Takeaway
In elite athletes with PTS ≥10° and failed ACLR, combining supratuberosity slope-reducing osteotomy with revision ACLR achieved 100% return to preinjury sport level at a mean of 12.1 months with no graft failures at mean 58.8-month follow-up.

Summary
This retrospective two-center case series evaluated revision ACLR combined with supratuberosity slope-reducing osteotomy in 19 elite athletes with failed ACLR and PTS ≥10°. All 19 athletes returned to preinjury competition level at a mean of 12.1 months, with IKDC improving from 44.2 to 92.3 and Lysholm from 46.8 to 96.9 (both P<.001). Mean PTS was reduced from 14.9° to 4.5° with no graft failures, no coronal malalignment, and no change in patellar height.
Key Limitation
The absence of a concurrent control group of high-PTS athletes undergoing revision ACLR alone prevents any causal inference about the osteotomy's contribution to the favorable outcomes.
Original Abstract
BACKGROUND
Increased posterior tibial slope (PTS) has been identified as a major risk factor for failure after anterior cruciate ligament reconstruction (ACLR). In athletes with high PTS undergoing revision ACLR, slope-reducing osteotomy (SRO) has been proposed to reduce anterior cruciate ligament graft forces and improve outcomes, but data regarding return to sport in elite athletes remain limited.
PURPOSE
To evaluate whether combining SRO with revision ACLR would allow elite athletes with increased PTS to return to their preinjury level of sport and, further, to assess clinical, functional, and radiographic outcomes.
STUDY DESIGN
Case series; Level of evidence, 4.
METHODS
This retrospective study included elite athletes with failed ACLR and PTS ≥10° who underwent revision ACLR combined with supratuberosity SRO between 2011 and 2023 at 2 centers. Return-to-sport (RTS) rate and time, clinical and functional outcomes (International Knee Documentation Committee [IKDC], Lysholm, Tegner, Anterior Cruciate Ligament-Return to Sport After Injury scale [ACL-RSI]), and radiographic parameters (PTS, hip-knee-ankle angle, and Caton Deschamps index) were evaluated.
RESULTS
Of the 22 ACLRs with SRO performed, 19 patients met the inclusion criteria. All athletes returned to competition at their preinjury level after a mean of 12.1 ± 2.3 months (range, 10-20 months), with a mean ACL-RSI score of 87.2 ± 6.7. Final scores, obtained at a mean follow-up of 58.8 ± 38.7 months (range, 24-169 months), showed excellent outcomes: IKDC score improved from 44.2 ± 10.7 preoperatively to 92.3 ± 6.7 postoperatively ( P < .001; 95% CI, 42-54), and Lysholm score improved from 46.8 ± 14.2 to 96.9 ± 3.1 ( P < .001; 95% CI, 35.2-65). Postoperative Tegner score corresponded to elite participation (mean, 9.7). Mean PTS decreased from 14.9°± 3° to 4.5°± 2.8°, with no significant changes in coronal alignment or patellar height. No graft failure or major complications occurred; reoperations were limited to staple removal for local discomfort.
CONCLUSION
In elite athletes with high PTS and failed ACLR, combining SRO with revision ACLR was safe and effective, enabling RTS with excellent clinical and functional outcomes.
