Background: In cases of recurrent anterior shoulder instability with a glenoid defect, Latarjet procedures are widely used for stabilization. Although complications with this procedure have been reported, few studies have comprehensively analyzed issues related to the Latarjet procedure. Purpose: To identify the overall complication rate of the Latarjet procedure used for anterior shoulder instability and to compare the rate of complications between arthroscopic and open approaches. Study Design: Systematic review; Level of evidence, 4. Methods: PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed by using the PubMed, EMBASE, Scopus, and Cochrane Library databases. Data on complications were extracted and classified as intraoperative, postoperative, or instability-related for further analysis. Quality assessments were performed with criteria from the Methodological Index for Nonrandomized Studies (MINORS). A quantitative synthesis of data was conducted to compare the complication rates between arthroscopic and open approaches. Results: A total of 35 articles were included in this analysis. The MINORS score was 11.89. A total 2560 Latarjet procedures (2532 patients) were included. The overall complication rate was 16.1% (n = 412). The intraoperative complication rate was 3.4% (n = 87) and included a 1.9% (n = 48) incidence of nerve injuries and a 1.0% (n = 25) incidence of iatrogenic fractures. Screw problems, vascular injuries, and conversion arthroscopic to open surgery each occurred at a rate of <1%. The postoperative complication rate was 6.5% (n = 166), and the most common complication was nonunion (1.3%; n = 33). The instability-related complication rate was 6.2% (n = 159) and included a 1.5% (n = 38) rate of redislocation, a 2.9% (n = 75) rate of positive apprehension test, and a 1.0% (n = 26) rate of instability. Overall, 2.6% (n = 66) of patients required an unplanned secondary operation after the initial surgery. The arthroscopic approach was associated with a higher rate of intraoperative complications compared with the open approach (5.0% vs 2.9%; P =.020) and a lower rate of instability-related complications (3.1% vs 7.2%; P < .001). Conclusion: The Latarjet procedure for anterior shoulder instability results in an overall complication rate of 16.1% and a reoperation rate of 2.6%. However, serious complications at short-term follow-up appear rare. When the arthroscopic approach was used, the rate of intraoperative complications was higher, although instability-related complications were lower when compared with the open approach.
Background Accurate measurement of the lower limb alignment is one of the most crucial factors in advanced knee osteoarthritis patients scheduled for surgery. Recently, EOS biplanar stereoradiography with three-dimensional reconstruction was developed. The purpose of this study was to compare radiographic parameters between conventional scanography and EOS in patients with advanced knee osteoarthritis who need surgical treatment. Methods A total of 52 consecutive patients (104 knees) with bilateral knee osteoarthritis of advanced stage (Kellgren-Lawrence [KL] grade 3 or 4) were retrospectively reviewed. We measured the hip-knee-ankle angle (HKA) on conventional scanograms. In EOS, we measured HKA, hip-knee-shaft angle, mechanical lateral distal femoral angle, and mechanical medial proximal tibial angle. To evaluate sagittal and axial plane alignment, knee flexion angle (KFA), and knee joint rotation (KJR) were also measured. Results Ninety knees were KL grade 4, and 14 knees were grade 3. The average HKA was 10.14° ± 6.16° on conventional scanograms and 11.26° ± 6.21° in EOS. HKA was greater in EOS than on conventional scanograms, and the difference (1.12°; range, −1.07° to 3.22°) was statistically significant ( p < 0.001). Significant correlations were observed on the difference in HKA and mechanical medial proximal tibial angle ( r = –0.198, p = 0.044), KFA ( r = 0.193, p = 0.049), and KJR ( r = 0.290, p = 0.003). In multivariable linear regression analysis, the difference in HKA had significant relationship with KFA (β = 0.286, p = 0.003) and KJR (β = 0.363, p < 0.001). Conclusions HKA measured on conventional scanograms and in EOS differed significantly and the difference had a significant correlations with KFA, KJR, and medial proximal tibial angle. Surgeons can consider these results before orthopedic surgery in patients who have advanced knee osteoarthritis.
With the rising number of anterior cruciate ligament (ACL) reconstructions, revision ACL reconstructions are becoming increasingly common. A revision procedure may be performed to improved knee function, correct instability, and facilitate a return to normal activities. When performing a revision reconstruction, the surgeon decides between a single-stage or a two-stage revision. Two-stage revisions are rarely performed, but are particularly useful when addressing substantial tunnel-widening, active infection, and concomitant knee pathology (e.g., malalignment, other ligamentous injuries, meniscal or chondral lesions). Among these potential scenarios requiring a two-stage revision, tunnel-widening is the most common cause; the first stage involves graft removal, tunnel curettage, and bone grafting, followed by revision ACL reconstruction in the second stage. The purpose of this article is to review the preoperative planning, surgical considerations, rehabilitation, and outcomes of two-stage revision ACL reconstructions and summarize the recent literature outlining treatment results.
The purpose of this study is to provide a systematic review of the definition, ideal surgical method, complications, and prognosis of trans-olecranon fracture dislocations. An electronic search was performed in the PubMed, EMBASE, Scopus, and MEDLINE databases. The eligibility criteria included retrospective clinical study and review article in subjects older than 18 years with trans-olecranon fracture dislocations. Trans-olecranon fracture dislocations are defined as fractures in which the stability of the ulnohumeral joint is lost due to the intra-articular fracture of the olecranon without disruption of the proximal radioulnar joint. The seven papers were included that met the eligibility criteria for the quantitative synthesis. Findings indicate that a pre-contoured plate was used in 88.3% of cases (68 of 77 reports), with no reports of complications, suggesting that the pre-contoured 3.5 mm plate is the first choice of treatment. Postoperative mean elbow range of motion for the flexion–extension arc was 121.1° and 146.5° for the pronation-supination arc. Methods for postoperative clinical scores included the Broberg/Morrey rating with a result of excellent or good in 82.9% of cases, the ASES score with a mean of 88.7, and the DASH score with a mean of 11.75. Complications included heterotopic ossification in 21.9% (23/105) of cases, arthrosis in 25.7% (27/105) of cases, nerve damage in 18.1% (19/105) of cases, and osteoarthritis in 14.3% (15/105). With better understanding of the mechanism of injury and proper diagnosis and treatment, findings of the current review suggest a positive outcome. PROSPERO registration No.: CRD42019126568.
Background The best option for the treatment of Neer type IIB lateral clavicle fractures remains controversial. The aim of this study was to compare outcomes and complications between pre-contoured locking plate osteosynthesis (PLPO) and coracoclavicular stabilization (CCS) using a TightRope for the treatment of type IIB fractures. Methods Forty-six consecutive type IIB fractures were treated with PLPO (17 cases) or CCS (29 cases). The mean follow-up period was 33.7 months (range, 12–144 months). Radiographic outcomes were evaluated using serial plain radiographs. Clinical outcomes were evaluated using the University of California, Los Angeles (UCLA) score, the American Shoulder and Elbow Surgeons (ASES) score, and subjective shoulder value (SSV). Results Of the 46 cases, complete bony union within 6 months after surgery was achieved in 42 cases (91.3%). The union rate was 100% (17/17) in the PLPO group and 86.2% (25/29) in the CCS group, showing a statistically significant difference ( p = 0.043). No significant differences in terms of UCLA score (32.8 vs. 32.1), ASES score (93.2 vs. 90.8), or SSV (89.1% vs. 90.3%) were observed between the PLPO and CCS groups. The complication rates were 17.6% (3/17; 2 cases of screw breakage and 1 case of stiffness) in the PLPO group and 37.9% (11/29; 4 cases of nonunion, 3 cases of stiffness, 2 cases of skin irritation, 1 case of superficial infection, and 1 case of coracoid button migration) in the CCS group, showing no statistically significant difference ( p > 0.05). Four cases with nonunion after CCS did not require reoperation because they had good to excellent clinical outcomes without radiographic progression. Conclusions Although a higher nonunion rate was observed in the CCS group compared with the PLPO group, satisfactory clinical outcomes were obtained for both groups. Both techniques can be regarded as useful options for the treatment of Neer type IIB lateral clavicle fractures.
