Opening-Wedge High Tibial Osteotomy Using Autograft versus Allograft: A Systematic Review and Meta-Analysis

J Knee Surg DOI: 10.1055/s-0039-1681065Bone grafting is a good alternative for filling the inevitable void that is created following opening-wedge high tibial osteotomy (OWHTO). This systematic review and meta-analysis evaluated whether bone grafting is necessary for OWHTO and the successful outcomes of OWHTO using either autograft (AU) or allograft (AL). All analyzed studies were acquired from PubMed, Medline, Embase, CNKI, Google Scholar, and Cochrane Library. Data were independently extracted by two coauthors and were analyzed using RevMan5.3. Mean differences, odds ratios, and 95% confidence intervals were calculated. Cochrane Collaboration's Risk of Bias Tool and Newcastle–Ottawa Scale were used to assess the risk of bias. In total, 10 studies were assessed including three randomized controlled trials and seven observational studies. The methodological quality of the trials ranged from low to high. The overall estimate demonstrated that the difference between OWHTO using AU and AL groups and OWHTO using no filling group was not statistically significant for the loss of correction, and complications, but OWHTO using no filling group statistically showed better knee society score. Pooled results of reoperations, lateral cortex breaches, complications, and clinical function assessments showed no significant difference between AU and AL materials. Using AL statistically reduced the operative time compared with using AU. OWHTO with or without bone graft does not affect ...

AbstractPurposeTo compare the “all-inside technique” for anterior cruciate ligament (ACL) reconstruction using a short, quadrupled semitendinosus tendon (ST4) autograft and suspensory cortical fixation on both the femoral and tibial side vs the “conventional technique” using a semitendinosus/gracilis (ST/G) autograft fix ed with a suspensory device on the femoral side and with an interference screw on the tibial side, in terms of clinical and functional outcomes.MethodsA total of 90 patients were enrolled, randomised into two groups, and prospectively followed. Group A comprised 45 patients treated ...

ConclusionsPost-meniscectomy pain syndrome and post-meniscectomy knee OA are common findings after meniscus resection. Short-term pain relief is provided by non-surgical management, mid-term pain relief by meniscus scaffolds, and long-term relief by MAT, though each has differing indications. In later stages, osteotomies and joint replacements are indicated.Level of evidenceIV.

In this study, fabricated composite scaffolds are made from polysaccharide biopolymers, namely gellan and guar gum, and hydroxyapatite by freeze drying method. The developed scaffolds of optimum concentration showed a maximum percentage degradation of 13.7% only until 21 days in phosphate buffered saline solution, and minimum swelling capacity. The mechanically stable scaffolds (compressive strength equivalent to cancellous bone region, ˜3-30 MPa) amongst them were then subjected to characterization tests—scanning electron microscopy, fourier transform infrared spectroscopy, X-ray diffraction, swelling r...

Abstract Articular cartilage defects, caused by trauma, osteoarthritis, or other diseases, always lead to severe joint pain and joint dysfunction. Without access to progenitor cells and the supply of blood and nutrients, the impaired articular cartilage would be short of the capability to self-repair. Although the present clinical treatments, including autogenous and allograft osteochondral transplantation, and microfracture technique, and so forth, have shown some efficacies, their drawbacks, such as donor insufficiency and poor-integrated with adjacent tissue, limit the satisfactory repair of articular cartilage...

McGahan, James L. ChenAbstractOsteochondritis dissecans (OCD) has been recognized for over 100 years yet still poses treatment challenges owing to both the avascular nature of articular cartilage and the inability to generate hyaline cartilage. The knee is most commonly involved, and without repair, patients have chronic knee pain, loose bodies, and early-onset osteoarthritis. There are a number of surgical techniques for repai...

CONCLUSIONS: These data suggested that our technique is a successful procedure for the trapeziometacarpal joint arthrodesis. Cross-shaped bone grafts have the advantages of restoring thumb length and providing internal stabilization, especially for rotational force. No complications arose at the bone harvest site of the iliac crest. The procedure seems to be technically demanding, particularly for adapting the bone graft to perfectly match the shape of the defect. PMID: 30760141 [PubMed - in process]

ConclusionsOsteochondral allograft transplantation appears highly cost-effective though the cost per quality adjusted life year varies according to the widely varying costs of allografts. Based on one small study, revision OCA also appears very cost-effective, but more evidence is needed.Level of evidenceII.

Authors: Chompoosang T, D'Apolito R, Lacagnina C, Peretti G, Zagra L Abstract Rapidly progressive osteoarthritis (RPOA) is an uncommon subset of osteoarthritis (OA) characterized by rapid joint degeneration and destruction. The treatment of choice for these patients has traditionally been total hip arthroplasty (THA) because nonoperative treatments modalities are not effective. RPOA can lead to acetabular bone loss and consequently intraoperative technical difficulties making joint reconstruction in such patients a challenge for the surgeon. The purpose of this study was to determine the clinical and radiological r...
