๐Ÿšจ Exciting Clinical Milestone

๐Ÿฆต OrthoPureยฎXT from Tissue Regenix Group is a safe, off-the-shelf product in ACL Reconstruction!

The first-in-human 5-year clinical study of a novel porcine xenograft for ACL reconstruction has just been published in the Journal of Experimental Orthopaedics.

โœ… Key Highlights:
- 40 patients treated with a decellularized porcine tendon graft
- No immunogenic response observed
- Clinical outcomes comparable to autografts and allografts
- Graft ruptures limited to young male patients
- MRI and radiographic results support safety and performance

This study marks a significant step forward in expanding graft options for ACL surgery, offering a biomechanically sound and immunologically safe alternative.

Cartilage Image of the month โ€“ September 2025 ๐Ÿ๐Ÿ‚

๐Ÿ–ผ๏ธ Selected as the Cartilage Image of the Month September, this case was submitted by Dr. Andrejs Finogejevs (LV).
A 42-year-old active female office worker presented with pain, stiffness, and limited knee motion for two months (VAS 4โ€“6). Conservative treatment included NSAIDs and a knee brace. Imaging revealed a 1.5 x 2.5 cm cartilage defect on the medial femoral condyle.

Dr. Finogejevs performed a mini-open chondroplasty and microfracture. At 6 months post-op, the patient reported no pain, had returned to sports activities, and was fully weight-bearing without crutches.

At 6 months post-op, the patient was pain-free, active in sports, and walking without crutches. The one-year follow-up image shows a well-filled defect, with cartilage regeneration reaching the level of the surrounding tissueโ€”indicating a successful outcome and excellent tissue remodeling.

ย 
Congratulations to the Course Directors Jos Malda, Roel JH Custers, and Jasmijn Korpershoek for putting together an exciting program!
Participants enjoyed insightful lectures on chondrocytes, cartilage ECM, in vitro and in vivo models, and cutting-edge bioprinting technologies. The hands-on lab sessions featured cell seeding on a collagen membrane, bioprinting, on-chip systems, and cartilage and bone scoring.
Participants had the opportunity to see the fantastic infrastructure of the labs at UMC Utrecht and the Regenerative Medicine Centre Utrecht. ๐Ÿฅ๐Ÿ”ฌ

Off to new heights with Chondro-Gideยฎ! โ›ท๏ธ

Our this monthโ€™s Cartilage Image of the Month speaks almost for itself. Alexandra Schรถllkopf (Germany) explored the mountains of Georgia (Miketi Mountain, Gudauri) on 3.200 meters above sea level and was ready enough in case of a cartilage defect. ๐Ÿ˜‰

As high as Chondro-Gideยฎ can go, as high is the pile of evidence that speaks for AMICยฎ in cartilage repair. More than 140 peer-reviewed studies document the good outcomes of AMICยฎ. ๐Ÿ“š

๐Ÿ‘‰ More than 10 years of follow-up data has been published and there is good evidence for AMICยฎ in the knee, the ankle, the MTP and the hip joint.

๐Ÿ–ผ๏ธ Our this monthโ€™s Cartilage Image of the Month is coming from Kailash Devalia, UK.

๐Ÿ‘‰ Freibergโ€™s disease is a rare condition affecting the metatarsal head, often leading to pain and functional impairment. We present a case of a 17-year-old female who initially presented with persistent pain and stiffness in her left second toe, unresponsive to conservative management. MRI confirmed Freibergโ€™s disease of the second metatarsal head.
Due to failure of nonoperative treatments and significant impact on daily activities, she underwent theย AMICยฎ procedure with calcaneal bone grafting as a joint-sparing approach, reserving arthroplasty as a potential future option.

๐Ÿ™Œ The patient experienced complete pain relief and returned to full daily and recreational activities within six months postoperatively. One year later, she developed Freibergโ€™s disease of the second metatarsal of the contralateral foot and underwent the same surgical procedure. Serial postoperative imaging at 1, 3, 5, and 7 years demonstrated stable results, with near-complete remodeling of the metatarsal head and no need for revision surgery.

๐Ÿ’ก This case highlights the efficacy of the AMICยฎ technique with bone grafting as a durable joint-preserving strategy for Freibergโ€™s disease, offering excellent long-term outcomes.
