Effect of posteromedial corner injury on stability and second-look arthroscopic findings after posterior cruciate ligament reconstruction using allograft.

PURPOSE: The purpose of our study was to assess effect of posteromedial corner(PMC) injury on clinical outcomes and second-look arthroscopic findings after posterior cruciate ligament(PCL) reconstruction using Achilles tendon allograft. METHODS: A total of 51 patients who underwent arthroscopic PCL reconstruction for PCL rupture and second-look arthroscopy were retrospectively enrolled in our study from 2009 to 2019. The subjects were divided into two groups: PMC intact group included 31 patients; and PMC injured group included 18 patients. At least 1 years follow-up, clinical outcomes and arthroscopic findings including synovial coverage, tension were evaluated. RESULTS: Arthroscopic findings including the synovial coverages, tension showed significantly better at PMC intact group. (p < 0.005) but, no statistic difference was seen in clinical outcomes including KT-2000 value, last Lysholm score, posterior drawer test. CONCLUSION: For PCL ruptures with PMC injuries, treatment for PMC should be considered due to graft status. LEVEL OF STUDY: IV.

Tendon Subluxation After Surgical Release of the First Dorsal Compartment in De Quervain Disease.

We aimed to determine whether dorsoulnar incision elevating radial flap and immobilization for the treatment of de Quervain disease have an advantage over simple midline incision and early mobilization, respectively, in terms of tendon subluxation and clinical outcomes. Forty-six patients with de Quervain disease were randomly divided into 2 groups (midline incision vs dorsoulnar incision) and 2 subgroups (immobilization vs early mobilization). Subluxation of intracompartmental tendons was measured in dynamic wrist positions at 12 and 24 weeks using ultrasonography. The DASH (Disabilities of the Arm, Shoulder, and Hand) and visual analog scale scores and grip and pinch strengths were evaluated. At 24 weeks, the tendons were displaced voloradially in wrist volar flexion (1.25 mm in midline incision vs 0.36 mm in dorsoulnar incision, P = 0.001), whereas the tendons were displaced dorsoulnarly in wrist extension (0.95 mm in midline incision vs 1.78 mm in dorsoulnar incision, P = 0.041). There were no significant differences in tendon displacement between early mobilization and immobilization groups. Clinical outcome measures showed no variation between the groups, and no significant correlation occurred with tendon subluxation. Dorsoulnar incision and postoperative immobilization do not have advantage over midline incision and early mobilization, respectively. However, tendon subluxation after release of the first dorsal compartment for de Quervain disease does not affect clinical outcomes.
