BACKGROUND Generally, a glenoid bone loss greater than 20% to 25% is considered critical for poor surgical outcomes after a soft tissue repair. However, recent studies have suggested that the critical value should be lower. PURPOSE To determine the critical value of anterior glenoid bone loss that led to surgical failure in patients with anterior shoulder(More)
PURPOSE The purpose of this article was to assess the clinical outcome of high tibial osteotomy (HTO) with articular cartilage surgery compared with unicompartmental knee arthroplasty (UKA) in unicompartmental osteoarthritis (OA). METHODS We designed retrospective study and evaluated 47 patients with unicompartmental OA (Kellgren-Laurence [K-L] grade ≥III(More)
PURPOSE To introduce an arthroscopically assisted coracoclavicular (CC) fixation technique using a cortical fixation button device and to evaluate the clinical and radiologic outcomes in patients with acute acromioclavicular (AC) dislocation who were treated with the technique. METHODS Twenty-one consecutive patients with grade III and V acute AC(More)
BACKGROUND Recently, minimally invasive plate osteosynthesis (MIPO) has been widely used for the treatment of proximal humeral fractures. However, there is concern about whether the MIPO in comminuted proximal humeral fractures is also comparable to open plating. The purpose of this study was to compare the clinical and radiographic outcomes of open plating(More)
BACKGROUND The repair of anterior L-shaped tears is usually difficult because of the lack of anterior rotator cuff tendon to cover the footprint. The biceps tendon is usually exposed from the retracted anterolateral corner of the torn tendon and can be easily used to augment rotator cuff repair. Hypothesis/Purpose: This study compared the clinical outcomes(More)
BACKGROUND The authors analyzed clinical and radiological 6-year follow-up results after total knee arthroplasty (TKA) with NexGen LPS-flex® and implant survivorship. METHODS The medical records of 80 patients that underwent 122 TKAs using NexGen LPS-flex® from February 2005 to November 2008 and followed up for at least 6 years were reviewed. The Internal(More)
BACKGROUND There have been numerous reports of clinical outcomes associated with tendon healing after repair that suggest a nonhealed tendon has a negative effect on postoperative clinical outcomes. However, to our knowledge, there has been no report on the relationship between tear size progression of nonhealed tendons and clinical outcomes. (More)
Purpose The purpose of this study was to evaluate the mid-term outcomes of anatomic anterior cruciate ligament (ACL) reconstruction using two anteromedial (AM) portals by comparing with short-term follow-up results. Materials and Methods Fifty patients who were treated by ACL reconstruction using a two AM portal technique were evaluated retrospectively.(More)
BACKGROUND Bleeding control is critical after total knee arthroplasty (TKA). The purpose of this study was to evaluate the optimal time to release the clamped drain after TKA. METHODS We performed unilateral TKA in 120 patients using three methods of drainage. Group A (N = 40) had a 3-hour clamp applied, and group B (N = 40) had a 4-hour clamp applied.(More)
PURPOSE The purpose of this study was to compare the prevalence of concomitant intra-articular pathologies and clinical manifestations after arthroscopic stabilization between patients with symptomatic anterior instabilities following recurrent shoulder subluxations and dislocations. METHODS Among patients who underwent arthroscopic stabilization, 28(More)
