Hip arthroscopy is currently being leveraged in the diagnosis and treatment of a wide range of hip joint problems. In fact, great advancements in hip arthroscopy have resulted in an ever-expanding number of indications to which it is being applied. Minimally invasive hip arthroscopy allows for quicker initiation of rehabilitation and has attracted much attention as the field becomes increasingly focused on surgeries designed to preserve joints. This review aims to summarize the recent advances, applications, and impact of hip arthroscopy.

PURPOSE: We evaluated the morphologic change of cam lesion of femoroacetabular impingement (FAI) using 3-dimensional computed tomography (3D-CT) at the minimum 2-year follow-up and estimated its relationship with clinical outcomes. MATERIALS AND METHODS: Between February 2007 and March 2014, all patients who underwent hip arthroscopic femoroplasty under the impression of FAI were retrospectively evaluated. We selected patients who received 3D-CT and were followed-up for more than 2 years. We estimated the quantitative volume of femoroplasty, alpha angle and femoral head-neck offset using 3D-CT. RESULTS: Thirty-two patients (37 cases) were selected in our study. The mean age was 31.2 years (16–69 years) and the mean follow-up duration was 47.3 months (26–119 months). The mean resection volume measured after femoroplasty using 3D-CT was 48.9 mm2 (13.2–106.4 mm2), and follow-up mean resection volume was 37.9 mm2 (7.83–90.37 mm2). A little bit of the mean volumatic overgrowth of the resection area between immediate postoperative and last follow-up was shown; however, there was no statistically significant difference in the mean values (p>0.05). The clinical outcomes showed a significant improvement during the perioperative and follow-up periods in all categories (p < 0.05). CONCLUSION: There was no significant regrowth of cam lesion after femoroplasty for FAI at maximum 9 years. Moreover, in most cases, clinical outcomes were improved. This suggests that we were able to achieve good clinical outcomes without harmful anatomical regrowth of cam deformity using arthroscopic femoroplasty.

We analyzed the causes leading to total hip arthroplasty (THA), aimed to clarify the incidence of femoroacetabular impingement (FAI) among the causes, and compared the incidence in Korea with those in other countries. From January 2000 to December 2014, 1,206 hips of 818 patients who underwent primary THA at our institute were reviewed retrospectively in terms of radiographs and electronic charts. The radiographs and radiographic parameters were reviewed and measured by 2 of the authors, who are orthopedic surgeons. Patients were categorized in terms of the causes leading to THA as primary osteoarthritis (OA), rheumatoid arthritis (RA), posttraumatic arthritis, post infectious arthritis, avascular necrosis (AVN) of the femoral head, fracture of the femoral head or neck, ankylosing spondylitis (AS), developmental dysplasia of the hip (DDH), Legg-Calvé-Perthes disease (LCPD), FAI, and others. There were 32 patients (3.91%) in the primary OA group, 41 (5.01%) in the RA group, 84 (10.27%) in the posttraumatic arthritis group, 39 (4.77%) in the post infectious arthritis group, 365 (44.62%) in the AVN group, 39 (4.77%) in the fracture group, 21 (2.57%) in the AS group, 52 (6.36%) in the DDH group, 71 (8.68%) in the LCPD group, 52 (6.36%) in the FAI group, and 22 (2.69%) in the ‘other’ group. The causes leading to THA in Korea differ from those in Western countries. FAI could be causes of severe secondary OA that requires THA in Korea, therefore symptomatic FAI should not be neglected.

PURPOSE: To report the radiographic and clinical results of 6.5 mm cancellous full threaded buttress screw or Steinmann pin fixation to maintain a reduction of calcaneal posterior facet depression fracture. MATERIALS AND METHODS: From June 2009 to June 2012, 50 consecutive cases with calcaneal joint depression fracture that underwent open reduction and screw or pin fixation were enrolled in this study. A 6.5 mm cancellous full threaded screw was inserted from the posteroinferior aspect of the calcaneal tuberosity to the posterior facet (group A) or Steinman pin was inserted from the posterosuperior aspect of the calcaneal tuberosity to the calcaneocuboidal joint (group B). Both preoperative and postoperative Bohler and Gissane angles were measured radiographically, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale on the final follow-up were assessed. RESULTS: The mean age of patients was 44.1 years, and the mean follow-up period was 27.2 months. According to the Sanders classification, 28 cases were type II and 22 cases were type III. In Sanders type II, Bohler and Gissane angles improved significantly from 10.1degrees and 126.2degrees preoperatively to 27.2degrees and 117.1degrees, respectively, in the immediate postoperative radiograph, and at the final follow-up, 26.6degrees and 118.6degrees, respectively. In Sanders type III, Bohler and Gissane angles improved significantly from 5.0degrees and 129.8degrees to 29.9degrees and 119.3degrees, respectively, in the immediate postoperative radiograph, and 26.9degrees and 120.2degrees at the final follow-up. All cases achieved bony union, and the average period until complete union was 13.3 weeks. AOFAS ankle-hindfoot scale was 82.6 in Sanders type II and 77.3 in Sanders type III at the final follow-up. CONCLUSION: A 6.5 mm cancellous full threaded buttress screw or Steinman pin fixation is a noninvasive treatment method with a merit of being able to maintain the bearing capacity of the posterior facet comparable to plate fixation.

Traumatic hip fracture-dislocations are associated with chondral and labral pathology as well as loose bodies that can be incarcerated in the hip joint. Incarceration, such as interposed labrum between acetabulum and femoral head that is not readily visualized preoperatively, is a rare but important cause of pain and can potentially be a source for early degeneration and progression to osteoarthritis. We present three cases, arthroscopic surgery of incarcerated acetabular osseo-labral fragment following reduction of traumatic hip fracture-dislocation.

PURPOSE: The aim of this study was to assess the feasibility and safety of laparoscopic multivisceral resection of colorectal cancer adherent to adjacent organs. METHODS: We reviewed retrospectively 32 patients undergoing elective laparoscopic multivisceral resection for colorectal cancer adherent to adjacent organs between June 2003 and May 2009. Survival curves were generated by Kaplan-Meier method. RESULTS: The median age of 32 patients was 73 years. In 10 of 17 rectal cancer patients (59%), neoadjuvant chemoradiation was performed. All the surgeries were completed laparoscopically. The postoperative complications occurred in 21.9% and there was no operative mortality. The median length of hospital stay was 15.5 days. In 23 of 32 patients (72%), the resection was considered curative. Median follow-up period of all patients and curatively resected patients was 22 (range, 2~65) months, 34 (range, 4~65) months respectively. Local recurrence rate, the 3-year overall survival rate and the 3-year disease free survival rate of 23 curatively resected patients was 4.3%, 92.9% and 84.4%, respectively. CONCLUSION: Laparoscopic multivisceral resection is feasible and safe in highly selected patients with colorectal cancer adherent to adjacent organs. Further validation is needed.

PURPOSE: The purpose of this study is to evaluate the risk factors for clinical anastomotic leakage after laparoscopic resection for rectal cancer. METHODS: From March 2001 and February 2006 in Seoul Veterans' Hospital, the prospective laparoscopic colorectal resection database identified 101 patients who a had laparoscopic rectal resection with colorectal or coloanal anastomosis. The associations between clinical anastomotic leakage and patient-, tumor-, surgery- and laparoscopic-related variables were studied. RESULTS: The rate of clinical anastomotic leakage was 4 percent (4 of 101). The patient-related variable significantly associated with clinical anastomotic leakage was preoperative radiotherapy. The surgery-related factor that turned out to be significant was anastomosis situated less than 5 cm from the anal verge. No tumor- or laparoscopic-related variables were significantly associated with clinical anastomotic leakage. CONSLUSIONS: A protective ileostomy should be considered after a laparoscopic rectal resection for an rectal cancer for anastomosis situated less than 5 cm from the anal verge, particularly when preoperative radiotherapy is being used.

PURPOSE: The purpose of this study is to assess the periopertive morbidity and mortality rates in relation to the principal variables in aged patients who undergo laparoscopic colorectal resection. METHODS: From March 2001 to March 2006, the prospective laparoscopic colorectal resection database was used to identify 233 patients. Among them, 132 were 70 years of age or older and they were classified as the aged group. 101 were younger than 70 years of age and they were classified as the younger group. RESULTS: Comorbidity was more common in the aged group than in the younger group (67.4% and 53.5%, respectively) (P=0.030). There were higher ASA scores in the aged group (I: 2.3% II: 68.2% III: 29.5%) than in the younger group (I: 27.7% II: 56.4% III: 15.8%) (P<0.0001). There was a higher postoperative complication rate for the aged group than for the younger group (25.0% and 8.9%, respectively) (P=0.002). Only one case of mortality (0.8%) was found in the aged group. The period of the postoperative hospital stay was longer for the aged group than that for the younger group (21.9+/-3/416.3 days and 16.3+/-3/48.1days, respectively) (P= 0.002). For the aged group, univariate analysis revealed that the operative procedure, disease, the T stage and the operation time were significant variables for the postoperative complications, and multivariate analysis identified the operation time as an independent variable faor the postoperative complications. CONCLUSION: More prudent care is needed to prevent postoperative complications for the aged patients who undergo laparoscopic colorectal resection, and particularly for those who can be expected to have a longer operation time.

Subchondral bony cyst, large solitary or multiple cysts in acetabular dome usually exacerbate progression to degenerative osteoarthritis in the hip joint. But it can be treated through arthroscopic intervention. We report two cases that treated by arthroscopic curettage and bone graft for subchondral bony cysts in early osteoarthritis of the hip joint, and it may delay progression to moderate osteoarthritis.
