No Clear Difference in Clinical Outcomes Between Knotted and Knotless Arthroscopic Bankart Repair: A Systematic Review.

PURPOSE: To analyze whether the arthroscopic Bankart repair using a knotless suture anchor has a better functional outcome than the conventional knot-tying Bankart repair. METHODS: A comprehensive literature search was done in the PubMed, Scopus, Embase, and Cochrane databases in May 2023. Studies comparing the clinical outcome of Bankart repair using knotless and knot-tying techniques were included in the study. In vitro, animal, and Level IV and V studies were excluded. The risk of bias in randomized controlled trials was calculated according to the RoB 2 tool, and for nonrandomized studies, Methodological Index for Non-Randomized Studies criteria were used. Statistical analysis was done using RevMan software. RESULTS: A total of 9 studies, including 2 randomized controlled trials and 7 nonrandomized comparative studies involving 720 patients, were included in the systematic review. The ROWE score ranged from 81.7 to 94.3 in the knot-tying group and 86 to 96.3 in the knotless group. Visual Analog Scale scores at the final follow-up ranged from 0.1 to 1.7 in the knot-tying group and 0.7 to 2.5 in the knotless group. The rate of redislocation, subluxation, and revision surgery in the knot-tying group ranged from 0% to 14.7%, 16.7% to 29.7%, and 1.6% to 17.6%, respectively, whereas that in the knotless group ranged from 2.4% to 23.8%, 7.4% to 22.2%, and 2.4% to 19%, respectively. The mean external rotation was 54° to 65° in the knot-tying group and 61° to 99° in the knotless group. The mean forward-flexion was 164 to 172 in the knot-tying group and 165 to 174 in the knotless group. Our subjective synthesis does not reveal any difference in the outcome between the 2 groups. CONCLUSIONS: The available literature does not demonstrate a clear difference in functional outcomes, residual pain, and rate of complications as redislocation, subluxation, and revision surgery between Bankart repairs performed with knotted and knotless anchors. LEVEL OF EVIDENCE: Level III, systematic review of Level I to III studies.

Shortening dome osteotomy for correction of severe cubitus varus secondary to malunited supracondylar fractures in children.

The results of conventional corrective procedures remain suboptimal for severe cubitus varus deformities (> 30°) in children. We present the results of shortening dome osteotomy for the correction of such deformities. PATIENTS AND METHODS: We present retrospective review of prospectively collected data of 18 patients (11 boys and 7 girls) who underwent shortening dome osteotomy between January 2011 and December 2019 for severe cubitus varus deformities (> 30°) secondary to malunited supracondylar fracture. The procedure involved the removal of convexo-concave bone (5-8 mm wide) between the two domes. Humero-ulnar angles, lateral condylar prominence index (LCPI), and elbow range of movements were recorded preoperatively and postoperatively. RESULTS: Mean age was 7.5 years (range 5 years-11 years). Indication for surgery was poor cosmesis in all the patients and tardy ulnar nerve symptoms in three patients. Mean preoperative humero-ulnar angle was 26.1° varus (range 22°-34°), while it was 7.1° valgus (range 0°-12°) for contralateral normal elbow. They were followed for a mean duration of 2.2 years (range 12 months-5.8 years). The mean postoperative valgus angle achieved was 7.3° (range 2°-12°) as total angular correction achieved was 34.4° (range 30°-44°) (p < 0.001). Radiological healing was observed in all the patients at mean duration of 7.1 weeks (range 5 weeks-9 weeks). Mean preoperative and postoperative LCPI were - 2.4 (range +4.7 to - 10.5) and - 1.7 (range +4.5 to - 5.1), respectively (p = 0.595). Three patients had pin tract infections and two of them responded to aseptic dressings and oral antibiotics, while another required early pin removal and additional protection in splint. All patients regained preoperative arc of motion within 6 months after the procedure. CONCLUSION: Shortening dome osteotomy is a safe and effective method for correcting severe cubitus varus deformities (> 30°) secondary to malunited supracondylar fracture in children.

Preventable iatrogenic cause of foot-drop in knee injuries with literature review.

PURPOSE: Common peroneal nerve palsy is quite disabling and every effort should be made to prevent its injury during the treatment. METHODS: We retrospectively reviewed the prospectively collected data of 7 cases of tibial plateau fractures in association with proximal fibula fracture from January 2019 to September 2019 who presented to emergency room of our hospital. RESULTS: In addition to fibular neck fracture, the first case had type 6 tibial plateau displaced fracture and the second case had displaced acetabular fracture with instability of knee with tibial tuberosity avulsion. common peroneal nerve palsy developed following application of distal tibial skeletal traction in both the cases. Other 6 such cases remained neurologically intact as traction was not applied to them. CONCLUSION: Such iatrogenic complication could have been prevented if the injury pattern of "concomitant medial and lateral columns" of the proximal leg is kept in mind by the treating surgeon before applying skeletal traction.

Prospective comparative evaluation of intraoperative joint stability and component placement between posterior approach to hip and its quadriceps coxae sparing modification for primary hip arthroplasty.

Background: Efforts at minimizing the propensity of posterior approach of hip for post-operative dislocation after total hip arthroplasty have been a subject of continual research. We comparatively evaluated the posterior approach to hip and its quadriceps coxae sparing (QCS) modification with regard to joint stability and component placement.Questions/Purposes: (1) Does sparing of Quadriceps Coxae tendons vis a vis their sectioning in posterior approach help in achieving better intraoperative stability? (2) Does sparing of Quadriceps Coxae tendons come in the way of adequate surgical exposure sufficient to place hip components accurately? (3) Does sparing of Quadriceps Coxae tendons result in better early functional outcome? Methods: Seventy-two patients requiring THA were enrolled prospectively and randomized into two groups: group A (posterior approach) and group B quadriceps coxae sparing (QCS) approach. They were compared for intraoperative joint stability, accuracy of component placement, duration of surgery, blood loss, any event of hip dislocation, and functional outcome. Results: QCS approach resulted in better intraoperative hip stability as the hips tolerated a higher value of 43.50±3.5° mean internal rotation (at 90° of flexion and 20° of adduction) in this group versus a mean value of 33.50±5.5° in posterior approach group (p < 0.01). No significant difference was observed for femoral version, acetabular inclination, and acetabular version in the two groups (p > 0.05). There was no difference between the two groups in terms of duration of surgery, intraoperative blood loss, and functional outcome at one year (p > 0.05). No event of hip dislocation was observed in QCS approach, whereas, one such event happened in the posterior-approach group. Conclusion: Preservation of the QC tendons improves the intraoperative stability of THA and they do not cause any hindrance in the exposure required for optimum component placement.

Association of Various Spinopelvic Parameters and the Quality of Life in Those With Degenerative Lumbar Scoliosis in the Indian Population.

Purpose The current study aimed to find any association between various spinopelvic parameters and the quality of life in patients with degenerative lumbar scoliosis (DLS) measured as per the Oswestry disability index (ODI) and visual analog scale (VAS) in the Indian population. Methods We included 20 DLS patients of more than 40 years with a Cobb angle of more than 10° and without any trauma, tumour, infection, or congenital scoliosis presented in our tertiary care centre in the study. The VAS and ODI were calculated for each patient. Radiological parameters were recorded for every patient, including sagittal balance, coronal balance, Cobb angle, pelvic incidence, pelvic tilt, and lumbar lordotic angle. We evaluated the results and sought any association between clinical and radiological variables for DLS. Results Patients with positive sagittal balance had significantly higher disability than those with neutral sagittal balance (p-value 0.007). Furthermore, patients with coronal imbalance had more severe pain (p-value 0.013) and disability (p-value 0.038) than those with neutral coronal balance. We also found that the ODI and VAS were not associated with any other spinopelvic parameters. Conclusion From the present study, we can conclude that in the Indian population, both positive sagittal and coronal imbalances are associated with poor functional status in patients with DLS. Therefore, while planning surgical correction for these patients, both coronal and sagittal balance are important and need to be considered.

A Comparative Evaluation of Combined Nerve Block Versus Periarticular Infiltration on Postoperative Pain Relief in Total Hip Arthroplasty.

Introduction: To minimize the side effects of the central neuraxial blockade to obtain postoperative pain relief, there has been an increasing preference for targeting the peripheral structures in patients undergoing total hip arthroplasty (THA). Patients and Methods: This prospective study was performed between September 2019 and September 2021 and involved 30 patients that were randomized to two groups. One group (n = 15) received combined nerve block (CNB) [obturator nerve, nerve to quadratus femoris, superior gluteal nerve, and femoral nerve], while another group (n = 15) received periarticular infiltrative analgesia (PIA). All the patients were given the same volume and composition of the drug cocktail (20 ml 0.5% ropivacaine, 1 ml (100 mcg) dexmedetomidine, and 29 ml normal saline). Results: The patients in group CNB had a significantly lower visual analog score (VAS) at 6, 12, 18, 24, 30, 36, 42 and 48 h after surgery (p < 0.05). Patients in group CNB required fewer (p < 0.001) doses of the rescue analgesic (1.67 ± 0.90 doses) as compared to group PIA (3.53 ± 0.64 doses). Time to the first rescue analgesia was significantly longer (p = 0.01) in group CNB (6.71 ± 2.36 h) as compared to group PIA (4.80 ± 1.26 h). However, patients in group PIA had significantly faster sensory (p < 0.001) and motor recovery (p < 0.001) as compared to group CNB. It took significantly longer (p < 0.001) to administer the nerve block (16.87 ± 1.80 min) as compared to periarticular infiltration (6.53 ± 1.18 min). There were no complications in either group. Conclusion: CNB registered significant superiority over PIA with respect to postoperative pain relief and time to rescue analgesia. However, the time taken to administer CNB was significantly higher and the patients in the PIA group had early recovery in sensory and motor modalities. Level of Evidence: III (therapeutic).

Is Posterior Femoral Neck Cortex an Obstacle in Achieving Sagittal Plane Balance of Uncemented Straight Femoral Stem?

Summary of Background Data: There is a paucity of the literature that aims to improve sagittal plane balance of femoral stem in hip arthroplasty. We have comparatively evaluated the effect of trimming the posterior cortex left in situ after femoral neck osteotomy and counter-clockwise rotation of starting awl with respect to their ability to achieve neutral alignment of femoral stem in sagittal plane. Questions/Purposes: (1) Which of the two techniques under reference is more reliable in achieving a sagittal plane balance of the femoral stem in the femoral canal? (2) Does either of the two techniques have the potential to adversely affect other parameters for the optimum placement of femoral stem? Patients and Methods: This prospective study involved a total of 60 patients (age group of 18 to 60 years) who underwent primary total hip arthroplasty (THA) through a standard posterolateral approach. They were randomized into groups (1) PNCT (n = 30): femoral canal preparation was done by posterior neck cortex trimming method; (2) CCRA (n = 30): femoral canal preparation was done by counter-clockwise rotation of starting awl. Postoperatively, radiographs and computed tomography were obtained and angle of femoral stem with the femoral canal in coronal and sagittal plane, femoral stem tip deviation in coronal and sagittal plane, anteversion of the femoral stem, duration of canal preparation and blood loss were analyzed between the two groups. Results: Based on our results, there is a significantly better sagittal alignment of the femoral stem within the femoral canal, both in terms of angle of the femoral stem with the femoral canal (p < 0.001) and the deviation of the femoral stem tip from the center of the medullary canal (p < 0.001) when the posterior neck cortex was trimmed. Canal preparation by trimming the posterior neck cortex took a mean of 11.93 min (range 8-15 min) against the mean duration of 6.87 min (range; 5 min to 9 min) in the other group (p < 0.001). Conclusion: Trimming the posterior femoral neck cortex after neck osteotomy results in better sagittal plane balance of uncemented straight femoral stem. Level of Evidence: III.

Short term results with the use of PLA antibiotic coated nail in open tibia fractures: A prospective study.

Background: Antibiotic impregnated cement coated nails have been described in literature with promising success rates. However, they need removal at a later stage. This study focuses on use of a PLA-precoated antibiotic nail that stops eluting antibiotic after a while and can be retained later as it behaves as a standard interlocking nail in the long run. Purpose: To study if PLA (polylactic acid) -antibiotic coated nails reduces infection and non-union rates and improve the functional outcome in open tibial shaft fracture cases. Materials and methods: In this prospective cohort study, we included 54 patients with open tibia shaft fractures treated with wound debridement and internal fixation using a reamed PLA (polylactic acid)-antibiotic coated nail (CE-certified, OSSIPRO, MatrixTM). Results: Forty patients with a Grade 2 and ten with grade 3A open tibial fracture, according to the Gustilo-Anderson classification, completed a minimum of six months of follow-up and were included in the analysis. At the final follow-up, four patients (all with grade 3A fracture) had an active infection, 10 (four of grade 2 and six of grade 3A) had non-union, the mean physical component score (SF-36 score) was 55.2 ± 20.10 (grade 2; 58.95 ± 9.99, grade 3A; 40.19 ± 16.37, P value 0.002), and the mean mental component score (SF-36 score) was 54.96 ± 23.5 (grade 2; 57.96 ± 16.63, grade 3A; 42.94 ± 23.75, P value 0.04). Furthermore, Multivariate analysis showed age and grade of fracture to be independently related to the development of infection and non-union. Conclusion: Although the use PLA-antibiotic coated nail looks promising, short-term results have revealed no additional benefit in terms of reduced infection rates, improved union rates or functional outcomes. Large multicentric randomized controlled trials and a long term follow up are advised to further explore the role of PLA coated antibiotic nails in open tibial fractures.

Shortening Dome Osteotomy for Correction of Complex Multiplanar Elbow Deformities: A New Surgical Technique.

Despite surgical advances in fracture management, it is not uncommon to find pediatric or adolescent patients with elbow deformities. Correction of severe deformities, often leaves the ingenuity of the treating surgeon asking for more. Various osteotomy techniques have been described in the literature for the correction of elbow deformities. Although, the concept of dome osteotomy did address certain inadequacies of the existing osteotomy techniques for distal humerus, but correction of complex deformities associated with deformation of trochlea and olecranon fossa still remain a surgical challenge which has not been adequately addressed in the literature so far. Our experience with the existing osteotomies for distal humerus led to the development of a new surgical technique of shortening dome osteotomy for correction of such complex multiplanar elbow deformities. Surgical steps, indications, and expected outcome is described.
