ACL Reconstruction with Autologous Hamstring Tendon: Comparison of Short Term Clinical Results between Rigid-fix and PINN-ACL Cross Pin

PURPOSE: To compare the short term clinical results of anterior cruciate ligament (ACL) reconstruction with autologous hamstring tendon between Rigid-fix and PINN-ACL Cross Pin for femoral side fixation. MATERIALS AND METHODS: 127 patients who underwent arthroscopic ACL reconstruction using autologous hamstring tendon and had been followedup for over than one year were enrolled for the present study. Rigid-fix was used in 71 cases (group 1), and PINN-ACL Cross Pin was used in 56 cases (group 2). Clinical and radiological results, operation time, and perioperative complications were compared amongst the two groups. RESULTS: The International Knee Documentation Committee subjective score and Lysholm score were 94 and 95 in group 1 and 87 and 91 in group 2, with no statistical difference (p=0.892, p=0.833), respectively. However, significant difference was observed in one-leg hop test between the two groups (p=0.032). Five cases in group 1 and 40 cases in group 2 were found to be associated with perioperative complications with statistical difference (p<0.0001). CONCLUSIONS: There was no resultant difference between the employment of PINN-ACL Cross Pin and Rigid-fix as femoral graft fixation for ACL reconstruction with hamstring tendon. However, PINN-ACL Cross Pin led to complications with extensive operation times. Hence, it needs further improvement of tools for minimization of complications.

Osteoarthritis of Hip in a Hypogammaglobulinemia Patient / 대한정형외과학회잡지

Hypoglobulinemia is characterized by functional or quantitative abnormalities of one or more components of the immune system. It is typically manifests as recurrent infections that usually start in childhood. These recurrent infections cause various clinical symptoms. Infectious or aseptic arthritis can develop, and especially in bone and joint abnormalities. No case of arthritis in a patients with hypogammaglobulinemia has been reported, so we report on the management of osteoarthritis of the hip in a hypogammaglobulinemia patient.
