Arthroscopic Medial Meniscal Transplant Using Multiple Fixation Techniques
Publication date: Available online 12 September 2019Source: Arthroscopy TechniquesAuthor(s): Michael DeFrance, Elizabeth Ford, Sean McMillanAbstractThe critical role of the meniscus in the biomechanics of the knee and articular cartilage preservation has led to an increased awareness of the importance of the meniscus. Meniscal allograft transplantation is a challenging surgical intervention that is saved as a last resort for patients who meet stringent criteria for salvage from meniscal deficiency. Proper arthroscopic implantation of a meniscal allograft takes precision and implementation of multiple fixation techniques to obtain a successful outcome.
Meniscal allograft transplantation has been reported to be an excellent treatment for young patients with symptoms related to meniscal deficiency. To date, several studies reporting on extrusion or shrinkage after a meniscal transplant have failed to correlate these findings with clinical outcomes. However, longevity, graft durability, and overall joint health have yet to be determined in the context of graft extrusion and shrinkage. Given a growing body of evidence showing varying degrees of shrinkage over time with no effect on functional outcome, allograft morphologic changes may not be as clinically important as once t...
To evaluate the incidence and degree of shrinkage of transplanted fresh-frozen meniscal allografts in a long-term period of>8 years and to investigate whether the shrinkage of allograft progresses and is associated with inferior clinical and radiologic outcomes after meniscal allograft transplantation (MAT) in the long term.
To assess the survivorship, clinical outcomes, and radiographic outcomes of patients who have undergone revision osteochondral allograft (OCA) to the knee in a retrospective case series.
To evaluate the influence of age on midterm clinical outcomes and failures of meniscal allograft transplantation (MAT), aiming at investigating the efficacy of MAT in patients older than 50 years.
We describe a technique for osteochondral allograft transplantation to the patella for an isolated patellar chondral lesion (unipolar).
J Knee Surg DOI: 10.1055/s-0039-1692999Osteochondral autograft transplantation (OAT) is a surgical option for repairing cartilage damage in knees, and can be performed using open or arthroscopic procedures. The aim of this review was to report clinical outcomes, postoperative complications, defect location, and defect size between open and arthroscopic OATs. Three electronic databases (EMBASE, PUBMED, and MEDLINE) were searched for relevant articles. In regard to eligibility criteria, knee articular damage cases solely treated with OAT were included and cases concomitant with ligament reconstruction, limb realignment, and ...
(1) To assess the incidence of postoperative opioid prescription refills in patients undergoing osteochondral autograft transplant (OAT) and osteochondral allograft transplant (OCA) procedures of the knee; (2) to evaluate the effect of filling preoperative opioid prescriptions on the incidence of postoperative filling; and (3) to assess the impact of age, sex, and diagnosis of low-back pain on postoperative opioid prescription filling.
When it comes to return to high-level sports participation, articular cartilage surgical treatment outcomes were historically abysmal, whereas osteochondral allografts have allowed return to sport at rates as high as 88%. However, although osteochondral allograft transplantation effectively reconstructs the damaged articular surface in affected knees, the grafts themselves do nothing to re-establish normal joint homeostasis, resulting in high reoperation rates. Return to sport should require recovery of nearly normal motion and strength, as well as magnetic resonance imaging showing intact cartilage, bony incorporation, and no effusion.
ConclusionThere is a large variety of pathology and procedures involving the use of various types of allografts in orthopedic reconstructive surgery of the elbow and forearm.
To report current data on return-to-sport rates and sports-specific patient-reported outcomes after osteochondral allograft (OCA) transplantation for cartilage defects of the knee.
