In this study, twenty patients were consecutively treated for their cartilage lesions with the synthetic plug technique. These patients were prospectively clinically evaluated with a mean follow-up of 34.15 months. Magnetic resonance imaging (MRI) was used for morphologic analysis of the cartilage repair. The patients included in this study showed a significant gradual clinical improvement after the osteochondral scaffold plug. However, this clinical improvement was not confirmed by the MRI findings of this cohort study. Subchondral bone changes were seen in all patients on MRI and deficient filling of the defect was noticed in in 30.7% of the cases at 24 months of follow-up. There was no evidence found to support osteoconductive bone ingrowth. Therefore, the use of this type of osteochondral scaffold plug in osteochondral repair is questionable.

Valgus stress radiography following superficial medial collateral ligament reconstruction using a modified LaPrade technique with adjustable loop femoral fixation / Aad Dhollander in Acta Orthopaedica Belgica, Vol. 86/2 (Juin 2020)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol. 86/2 (Juin 2020) . - p. 280-286 Titre : Valgus stress radiography following superficial medial collateral ligament reconstruction using a modified LaPrade technique with adjustable loop femoral fixation Type de document : texte imprimé Auteurs : Aad Dhollander, Auteur Année de publication : 2020 Article en page(s) : p. 280-286 Langues : Anglais (eng) Résumé : Purpose of this study was to assess postoperative laxity of MCL reconstructions utilizing a modified LaPrade superficial MCL reconstruction. We retrospectively reviewed post-operative valgus stress radiographs in 23 multiligament injured patients who underwent concurrent sMCL and cruciate ligament reconstruction by a single surgeon. Post- operatively, 23 patients underwent valgus stress radiographs that were assessed at a mean of 8.7 months (range: 4-13 months), and mean SSD was 0.64mm ± 0.42mm. Eight patients underwent both pre- and post-operative valgus stress radiographs. Post-operative (0.09mm ± 0.63mm) SSD was found to be significantly reduced compared to pre-operative (2.07mm ± 0.44mm) SSD (mean diff. = 1.98mm, 95% CI = 0.72-3.24, P=0.007). Inter-observer reliability value for medial compartment gap measurement was 0.91 with a 95% confidence interval of 0.34- 0.97. In conclusion, presented technique results in excellent static stability of the knee as measured by valgus stress radiography at a minimum of 6 months postoperative.
