[Meniscus transplantation as an option in case of painful arthrosis following meniscectomy].

The menisci play a role as shock absorbers and distribute the pressure uniformly over the joint cartilage. Other functions are: the nutrition of the joint cartilage, secondary stability and proprioception. In case of a torn meniscus, one should first attempt to suture the meniscus, followed by arthroscopic partial meniscectomy if suturing is impossible. In a large proportion of patients, arthrosis with pain and loss of function of the knee develops several years after the meniscectomy. In order to alleviate the symptoms of such arthrosis, a trial of meniscus transplantation was undertaken. In two long-term studies without a control group, the results of meniscus transplantation were reasonable. The results of medial meniscus transplantation are dependent upon the presence of an intact anterior cruciate ligament. The accepted indication for meniscus transplantation after meniscectomy is: disabling pain following (sub)total meniscectomy in a patient younger than 45-50 years of age with a normal alignment and a stable knee joint.

Human meniscal transplantation. Preliminary results at 2 to 5-year follow-up.

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. Three transplantations failed and the allografts were removed after 12, 20 and 24 months. Post-transplantation arthroscopy showed that most meniscal transplants had healed to the knee capsule. Histological examination showed revascularisation of the transplant and evidence of viable meniscal chondrocytes. The failures were probably caused by malalignment, resulting in impaired revascularisation of the graft.

Human meniscus transplantation.

The short term results of 15 cryopreserved non-tissue-antigen matched meniscus transplantations are described. The clinical outcome is satisfactory. Histological and histochemical studies showed that meniscuschondrocytes can survive cryopreservation and transplantation.

[Arthroscopic suturing of the meniscus].

A retrospective study (n = 12) was made of the results of arthroscopical suturing of menisci. Suturing is indicated in peripheral longitudinal meniscal tears in young, active people. Recurrent locking symptoms were found in one patient and quadriceps atrophy in another. The mean follow-up period was 8.2 (6-12) months. There were no complications. Our findings show that the method is feasible; the results were comparable with those reported in the literature and are encouraging for meniscus-sparing therapy.

[The physician at wit's end; a bezoar].

The case is described of a three-year-old Moroccan girl with iron deficiency anaemia and a bezoar resulting from trichotillomania and trichophagy leading to a slowly developed obstruction ileus. Causes, symptoms and treatment of the various forms of bezoar are discussed.

Meniscal allografts: evaluation with magnetic resonance imaging and correlation with arthroscopy.

PURPOSE: To correlate clinical results to magnetic resonance imaging (MRI) and arthroscopy after cryopreserved nontissue-antigen-matched meniscal transplantations. TYPE OF STUDY: Blinded; the observers were blinded for each others' assessment. MATERIALS AND METHODS: Sixteen consecutive patients were included in the protocol. First, clinical evaluation and MRI were performed. Second, within 24 hours, arthroscopy was performed. RESULTS: The clinical results showed better correlation between clinical results and arthroscopy than between clinical results and MRI. In the present study, MRI was not beneficial in evaluating meniscal transplants. CONCLUSIONS: Using more sophisticated MRI techniques, the correlation between clinical results, arthroscopy, and MRI could probably be improved.
