Case ReportsA novel technique for reconstruction of the medial patellofemoral ligament in skeletally immature patients.
Habitual or recurrent dislocation of the patella in the skeletally immature patient is a particularly demanding problem since the etiology is frequently multifactorial. The surgical techniques successfully performed in adults with patellar instability may risk injury to an open growth plate if applied to children. We present a technique that preserves femoral and patellar insertion anatomy of medial patellofemoral ligament (MPFL) using a free semitendinosus autograft together with tenodesis to the adductor magnus tendon without damaging open physis on the patellar attachment of MPFL. ⋯ Aftercare includes immobilization of the joint limited to 30° flexion using an above-knee splint for 2 weeks. No recurrent dislocation was observed in three patients (4 knees) at a mean follow-up time of 17.7 months. Both range of motion and radiological finding were restored to normal limits.

Calcium phosphate bone cement: a possible alternative to autologous bone graft. A radiological and biomechanical comparison in rat tibial bone.
Donor site morbidity is a problem after autologous bone transplantation. An injectable CaP bone cement indicates properties similar to bone. ⋯ The injectable CaP bone cement confirms its similarities to bone, implying that it can be used as an adjunct to secure bone fragments and as a possible alternative to autologous bone transplantation in clinical practice.
