How does periprosthetic joint infection after TKA in sub-Saharan Africa compare globally?

A two-centre cohort study from southern Nigeria found a PJI incidence comparable to high-income countries, and identified key modifiable perioperative risk factors.

🔑 Key findings:

· PJI incidence: 2.6% across 392 primary TKAs
· Staphylococcus aureus was the most common causative organism
· Patients treated for PJI still demonstrated meaningful functional improvement

Does pelvic width influence patellofemoral pain in Asian patients?

A study of 100 patients with anterior knee pain found no significant link between pelvic width and patellofemoral alignment—local knee anatomy is the real driver.

🔑 Key findings:

· No association between pelvic width and patellofemoral alignment or tracking

· No clinically meaningful sex-based difference in pelvic width

· Female patients had a higher prevalence of shallow trochlear morphology

Can hip dysplasia actually improve access to posterior CAM lesions? 🦴

New in JISAKOS: In dysplastic hips with a rare pistol-grip deformity, an arthrotomy via the Hueter approach allowed complete correction of large posterolateral CAM lesions prior to PAO.

🔑 Key findings:
• Posterior undercoverage facilitated access to the CAM deformity
• 100% elimination of the pistol-grip deformity
• Combined procedure increased operative time vs isolated PAO

Is an elevated TT–TG really just a “distance” problem?

New in : This study breaks the TT–TG into translational (bony morphology) and rotational (tibiofemoral rotation) components in patients with recurrent patellar instability.

🔑 Key findings:

• Both components independently elevate TT–TG

• Rotational alignment was the main driver in PFI patients

• Components were not correlated, suggesting distinct patient phenotypes

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.
