Unicondylar osteoarticular allograft reconstruction of the distal femur in a patient with a traumatic osteoaticular defect of the lateral femoral condyle

PurposeThe objective of this study was to report the clinical results for a patient with a post-traumatic osteoarticular defect of the lateral femoral condyle treated with unicondylar osteoarticular allograft reconstruction.MethodWe describe the case with a massive osteoarticular loss of the lateral femoral condyle combined with a grade IIIA open distal femoral diaphyesal fracture. The patient underwent unicondylar osteoarticular reconstruction with an allogenic fresh-frozen condyle.ResultsThere were no complications after the reconstructive procedure. At the five year follow-up, the patient showed a favorable clinical outcome with a full range of motion of the knee joint. Degenerative changes were seen in the graft compartment, but they did not cause serious functional limitations.ConclusionUnicondylar allograft reconstruction appears to be a surgical option for patients who suffer from a post-traumatic distal femoral osteoarticular defect in which only one condyle is absent or severely damaged.

Radial tears in the roots of the posterior horns of both the medial and lateral menisci combined with anterior cruciate ligament tear: a case report

We report a rare case of radial tears in the roots of the posterior horns of both the medial and lateral menisci associated with a chronic anterior cruciate ligament tear. Treatment included an arthroscopic pullout suture combined with anterior cruciate ligament reconstruction. At the 3-year postoperative follow-up, a second-look arthroscopic examination showed the posterior horns of both menisci to be well healed on the tibia. Manual knee laxity tests were negative and no side-to-side difference was detected by a KT-1000 arthrometer. The patient was able to perform outdoor activities without residual symptoms.
