Can dynamic knee valgus predict ACL graft failure?

New in : Dynamic valgus during return-to-sport testing was an independent predictor of graft re-rupture after ACL reconstruction—especially in male patients.

🔑 Key findings:

• Higher dynamic valgus increased risk of graft failure

• A threshold of 18–20° identified high-risk men

• No meaningful differences across graft types

New in : The Persian IKDC-SF has now been fully validated for patients with degenerative and sports-related knee injuries.

🔑 Key findings:

• Excellent reliability and validity across OA and ligament/meniscus injuries

• Strong correlations with Lysholm and SF-36 physical scores

• Clear minimal detectable change thresholds for clinical use

Can LET lower failure risk in revision ACLR—without sacrificing function?

New in : Adding a lateral extra-articular tenodesis (LET) to revision ACL reconstruction significantly reduced graft failure—while maintaining functional outcomes and return-to-sport rates.

🔑 Key findings:

• Graft failure: 3.3% with LET vs 18.3% without

• IKDC and Tegner scores were comparable between groups

• Return-to-sport rates were similar, including return to preinjury level

New in : After ACL reconstruction with lateral meniscus repair, cartilage degeneration may still progress—particularly in patients with radial/flap tears or higher BMI.

➡️ Meniscus injury and BMI were independent risk factors for cartilage deterioration.

New in : Among patients undergoing total knee arthroplasty, those with non-alcoholic fatty liver disease (NAFLD) had fewer postoperative complications than matched patients with non-alcoholic cirrhosis (NAC) — including lower rates of infection, pulmonary embolism, acute kidney injury, and reoperation.

➡️ Findings suggest non-cirrhotic NAFLD may not represent the same perioperative risk as cirrhosis.

This new video article details unicompartmental knee arthroplasty with simultaneous ACL reconstruction, using an image-based robotic platform for personalized planning and implant positioning. A joint-preserving option for carefully selected young, active patients.

💡 Key takeaway: ACL deficiency doesn’t have to rule out UKA.

Knee arthrofixation is a critical salvage option for patients facing chronic PJI and severe bone loss. 🩹🦾

This modular nail technique offers a functional alternative to amputation. Despite an average of nine prior surgeries, patients reported moderate-to-good quality of life scores at one year. While complication risks are high, it remains a vital pathway for limb preservation in complex revision scenarios.

New findings show: Patients with an ACL reconstruction and a concomitantly treated grade I or II MCL injury achieve results comparable to those with isolated ACL injuries. ⚽🦾

At the 2-year mark, data showed no significant differences in patient-reported scores or return-to-sport rates. Despite higher initial strength deficits, nonoperative management of the MCL does not compromise long-term recovery or psychological readiness.

New in - Preoperative osteoarthritis severity is a primary factor in how much patients improve after hip arthroscopy for FAIS.

While all groups improved, patients with no or mild osteoarthritis (KLG 0–1) saw steady, long-term gains. In contrast, those with moderate-to-severe osteoarthritis tended to plateau early and were less likely to reach a "patient-acceptable" symptom state.

Does biological augmentation really matter in acute patellar tendon repair? 🦵

New in : At ≥2-year follow-up, biological augmentation did not improve PROMs compared with isolated repair—but it significantly reduced failure rates.

🔑 Key findings:

• Functional outcomes were similar between techniques
• All failures occurred in the isolated repair group
• Augmentation was linked to lower (but normal) patellar height
• No increase in complications

25 years of ACLR—how have expert opinions changed? 🦵📊

New in : A 25-year survey of the ACL Study Group reveals how graft choice, surgical technique, and rehab philosophies have evolved alongside emerging evidence.

🔑 Key trends:

• Shift away from BTB toward hamstring and rising quadriceps autograft use
• Growing use of anteromedial femoral drilling and suspensory fixation
• More aggressive meniscus repair and a move toward 9-month return-to-sport

New video article outlines derotational tibial osteotomy for symptomatic patients with external tibial torsion >35°, restoring alignment, reducing Q angle, and correcting the lateral quadriceps vector.

💡 Key takeaway: Excessive external tibial torsion can drive anterior knee pain—and it’s correctable.
