In a prospective study, we evaluated the clinical results of 23 patients with a cryopreserved non-tissue-antigen matched meniscal transplant at a follow-up of from two to five years. These early results were satisfactory in 20 patients.
We describe a prospective survival analysis of 63 consecutive meniscal allografts transplanted into 57 patients. The lateral meniscus was transplanted in 34, the medial meniscus in 17, and both menisci (combined) in the same knee in six. For survival analysis we used persistent pain or mechanical damage as clinical criteria of failure. A total of 13 allografts failed (5 lateral, 7 medial, 1 medial and lateral). A significant negative correlation (p = 0.003) was found between rupture of the anterior cruciate ligament (ACL) and successful meniscal transplantation. A significant difference (p = 0.004) in the clinical results was found between lateral and medial meniscal transplants. The cumulative survival rate of the lateral, medial and combined allografts in the same knee, based on the life-table method and the Kaplan-Meier calculation, was 76%, 50% and 67%, respectively. The survival of medial meniscal allografts may improve when reconstruction of the ACL is carried out at the same time as meniscal transplantation in an ACL-deficient knee.
We have studied the results of reconstruction of a large skeletal defect using a vascularized fibula graft in 62 consecutive cases. We were particularly interested in factors that may significantly influence the outcome of union. In at least 90% of cases, eventual union can be expected in the reconstruction of large skeletal defects resulting from tumour resection, traumatic bone loss, or nonunion. The results of reconstruction for osteomyelitis were less favorable. Statistical analysis of the influences of bone graft polarity, internal fixation, additional bone graft polarity, internal fixation, additional bone graft material, and the length of the graft on the outcome of union revealed that the use of stable fixation and additional bone graft material significantly enhanced bone union, whereas the length or polarity of the graft had no influence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
