Temporary hemiepiphysiodesis is the procedure of choice to correct ankle valgus deformity in a skeletally immature patient. However, the literature is inconclusive regarding the ideal choice of implant and the timing of the surgery. In the current case report, a 9-year-old girl with multiple hereditary exostoses and unilateral ankle valgus deformity underwent tension band plate (TBP) hemiepiphysiodesis, and gained a modest correction at a rate of 0.61°/month. After 18 months of follow-up, there were no implant-related complications, and the functional outcome was also good. This case report shows a promising result of medial malleolar temporary hemiepiphysiodesis using a TBP for ankle valgus deformity in the pediatric population.

Underlying Pathology

Patellar dislocation is considered to be an infrequent complication post total knee arthroplasty, however identifying the exact underlying pathology that led to this condition is critical, rupture medial structure could result inpatellar subluxation or permanent dislocation. We present this case report of medial patellofemoral ligament rapture reconstruction that was done to treat this unfortunate event of chronic patellar permanent dislocation following total knee arthroplasty that was neglected for four months after sustaining a twisting injury.

Skeletally Immature Patient

Background: Adult medial patellofemoral ligament (MPFL) reconstruction techniques are not appropriate for the skeletally immature patient given the proximity of the distal femoral physis. Biomechanical consequences of reconstructions aimed at avoiding the physis have not been adequately studied. Purpose: To quantify the biomechanical effects of MPFL reconstruction techniques intended for skeletally immature patients. Study Design: Controlled laboratory study Methods: Four MPFL reconstruction techniques were evaluated using a computationally augmented cadaveric model: (1) Schoettle point: adult-type reconstruction; (2) epiphyseal: socket distal to the femoral physis; (3) adductor sling: graft wrapped around the adductor tendon; (4) adductor transfer: adductor tendon transferred to patella. A custom testing frame was used to cycle 8 knees for each technique from 10° to 110° of flexion. Patellofemoral kinematics were recorded using a motion camera system, contact stresses were recorded using Tekscan pressure sensors, and MPFL length was computed using an inverse kinematics computational model. Change in MPFL length, patellar facet forces, and patellar kinematics were compared using generalized estimating equation modeling. Results: Schoettle point reconstruction was the most isometric, demonstrating isometry from 10° to 100°. The epiphyseal technique was isometric until 60°, after which the graft loosened with increasing flexion. The adductor sling and adductor transfer techniques were significantly more anisometric from 40° to 110°. Both grafts tightened with knee flexion and resulted in significantly more lateral patellar tilt versus the intact state in early flexion and significantly higher contact forces on the medial facet versus the epiphyseal technique in late flexion. Conclusion: In this cadaveric simulation, the epiphyseal technique allowed for a more isometric ligament until midflexion, when the patella engaged within the trochlear groove. The adductor sling and adductor transfer grafts became tighter in flexion, resulting in potential loss of motion, pain, graft stretching, and failure. Marginal between-condition differences in patellofemoral contact mechanics and patellar kinematics were observed in late flexion. Clinical Relevance: In the skeletally immature patient, using an epiphyseal type MPFL reconstruction with the femoral attachment site distal to the physis results in a more isometric graft compared with techniques with attachment sites proximal to the physis.
