Objectives. Nylon sutures and skin staples are used commonly in total knee arthroplasty (TKA) surgical wound closure. However, there is no study that compares the wound healing efficacy and patient satisfaction scores of both techniques in the same knee. Methods. We randomised 70 patients who underwent primary TKA into two groups. In one group of 34 patients, the skin at the upper half of the wound was closed with skin staples and the lower half of the wound was closed with simple interrupted nylon sutures. In the other group of 36 patients, the skin at the upper half of the wound was closed with nylon stitches and the lower half of the wound was closed with skin staples. We recorded the wound closure time, pain score at the time of stitch removal, wound complication rate, patient satisfaction score, and the Hollander wound evaluation score at the post-operative periods of five days, 14 days, six weeks, three months, and six months. Each half wound was analysed separately. Results. The mean patient body mass index was 26.8 kg/m. 2. (standard deviation 6.3). A total of 70 nylon stitched wounds and 70 skin stapled wounds were analysed. There were no significant differences in wound complication rates, patient satisfaction score, and the Hollander wound evaluation score between both types of wounds (p > 0.05). The wound closure time for skin stapled wounds was significantly lower than the nylon stitched wounds (p < 0.001). However, the skin stapled wounds had a significantly higher pain score at the time of stitch removal (p < 0.001). Conclusion. Skin staples and nylon stitches had comparable results with respect to wound healing and patient satisfaction in TKA wound closure in non-obese patients. The benefit of skin staples over nylon stitches was a decrease in operative time, but was more painful upon removal. Cite this article: V. Yuenyongviwat.

Introduction. Wound closure following orthopaedic surgery is an important step requiring careful technique and suitable suture material. The use of subcuticular sutures has been advocated following use in animal models and has also been reported in the literature having been used in specialities such as Orthopaedic Surgery, Plastic Surgery and Obstetrics. Aims. The aim of this study is to assess the use of absorbable subcuticular INSORB® sutures in THR when compared with the standard Autosuture. TM. Signet. TM. metal skin staples. Patient satisfaction with wound appearance was measured at the six week review stage. Wound healing was also noted in the initial stages of recovery and at the six week review stage. Methods. A Randomised Control Trial of patients undergoing Primary Total Hip Arthroplasty (THR) was undertaken. Parameters measured included wound length, time taken for staple insertion, GP appointment for suture removal and patient satisfaction with wound appearance at 6 weeks post-operation. No exclusion criteria were applied in terms of the age, medical history, thromboembolic prophylaxis therapy or type of hip prosthesis. Results. 50 patients were recruited for this study. 25 patients had their wounds closed with INSORB® sutures and 25 patients had their wounds closed with skin staples. Wound healing was satisfactory at six weeks post operation. All patients in both groups described themselves as being satisfied or very satisfied with their wounds post-operation. Conclusion. INSORB® subcuticular skin staples act as an adequate method of skin closure in primary hip arthroplasty. They also provide an excellent cosmetic result and high levels of patient satisfaction

We carried out a blinded prospective randomised controlled trial comparing 2-octylcyanoacrylate (OCA), subcuticular suture (monocryl) and skin staples for skin closure following total hip and total knee arthroplasty. We included 102 hip replacements and 85 of the knee. OCA was associated with less wound discharge in the first 24 hours for both the hip and the knee. However, with total knee replacement there was a trend for a more prolonged wound discharge with OCA. With total hip replacement there was no significant difference between the groups for either early or late complications. Closure of the wound with skin staples was significantly faster than with OCA or suture. There was no significant difference in the length of stay in hospital, Hollander wound evaluation score (cosmesis) or patient satisfaction between the groups at six weeks for either hips or knees. We consider that skin staples are the skin closure of choice for both hip and knee replacements

Liquiband is a new tissue adhesive: It works like super glue – it is attached to the wound edges, it sets within seconds and lasts for about two weeks. The glue then flakes off automatically as the skin regenerates. There is no need for suture removal. A second step forms a waterproof layer over the wound. We compared in a prospective randomized trial the Liquiband glue to skin staples. Over a 9 month period (May 2005 to January 2006) we enrolled a total of 80 patients, 40 in each group. The patients were booked for elective limb surgery and agreed to participate in the study. The surgical wounds were closed in layers. The skin was then either closed with Liquiband or skin staples. A follow up was a weeks 2, 6 and 18. The wound healing was photographically documented. The wounds were assessed according to the Hollander wound scoring system and a patient satisfaction score. Ethical approval was obtained. The two groups were matched for sex, age, body-mass index and smoking. There was a similar total wound length in both groups. All wounds healed. In the Liquiband group 4 superficial infections occurred, one dehiscence due to glue removal by the patient. In the skin staples group we had 6 superficial infections. The patient satisfaction score was lower in the skin staple group (7.0 compared to 8.3 in the Liquiband group) and on the Hollander wound scoring system there were 10% more step-off borders and 12% more edge inversions in the skin staple group. The glue did not stain the skin or leave visible marks. The authors conclude that the Liquiband skin glue is safe and effective for elective surgery. The Liquiband skin glue does not require staple removal after wound healing and the waterproof closure of the wound provides additional safety

The purpose of this modified Delphi study was to obtain consensus on wound closure (including best practices for each tissue layer of closure) and dressing management in total hip arthroplasty (THA), using an evidence-based approach. The Delphi panel included 20 orthopedic surgeons from Europe and North America. Eighteen statements were identified (14 specific to THA and 4 relating to both THA and total knee arthroplasty) using a targeted literature review. Consensus was developed on the statements with up to three rounds of anonymous voting per topic. Panelists ranked their agreement with each statement on a five-point Likert scale. An a priori threshold of 75% was required for consensus. In Round 1, 15 of 18 statements achieved consensus via a structured electronic questionnaire. In Round 2, the 3 statements that did not achieve consensus were revised during a virtual face to face meeting. An additional 2 statements were edited for clarity. In Round 3, the 5 revised statements achieved consensus via a structured electronic questionnaire. Wound closure related interventions that were recommended for use in THA included: 1) barbed sutures over non-barbed sutures (shorter closing times and overall cost savings); 2) subcuticular sutures over skin staples (lower risk of infections and higher patient preference); 3) mesh-adhesives over silver-impregnated dressings (lower rate of wound complications); 4) negative pressure wound therapy over other dressings (lower wound complications and reoperations and fewer dressing changes); 5) triclosan coated sutures (lower risk of surgical site infection). Using a modified Delphi approach, a panel of 20 orthopedic surgeons achieved consensus on 18 statements pertaining to multi-layer wound closure and dressing management in THA. This study forms the basis for identifying critical evidence gaps within wound management to help reduce variability in outcomes during THA

Background. Surgical wound closure is not the surgeon”s favorite part of the total knee arthroplasty (TKA) surgery however it has vital rule in the success of surgery. Knee arthoplasty wounds are known to be more prone to infection, breakdown or delayed healing compared to hip arthroplasty wounds, and this might be explained by the increased tensile force applied on the wound with knee movement. This effect is magnified by the enhanced recovery protocols which aim to obtain high early range of movement. Most of the literature concluded that there is no difference between different closure methods. Objectives. We conducted an independent study comparing the complication rate associated with using barbed suture (Quill-Ethicon), Vicryl Rapide (polyglactins910-Ethicon) and skin staples for wound closure following TKA. Study Design & Methods. Retrospective study where the study group included all the patients admitted to our unit for elective primary knee arthroplasty in 2015, we excluded patients admitted for partial knee arthroplasty, revision knee arthroplasty or arthroplasty for treatment of acute trauma due to the relatively higher complication rates. All the patients notes were reviewed to identify wound related problems such as wound dehiscence, wound infection and delayed healing (defined as delayed wound healing more than 6 weeks). Results. 327 patients were included in this study; 151 in Quill group, 99 in staples group and 77 in the last group where the wound closed with Rapide. We identified 9 (5.9%) cases of wound dehiscence in the Quill group, 3 cases of wound dehiscence in each of other two groups (3.8%) with Rapide and (3%) with staples. On the other hand superficial wound infection was higher with staples with 6 (6%) cases of wound infection compared to the other groups, wound infection occurred in 2 patients (2.5%) with Rapide and 5 patients (3.3%) in the Quill”s group. Most of the delayed wound healing happened after using Quill where it is reported in 5 patients (3.3%) and the lowest was in staples group with 1 patient (1%) and slightly higher percentage in Rapide group 2 patients (2.5%). The total figure of wound related problems was the highest in Quill”s group with 19 reported cases (12.5%), lower in staples” group with 10 cases (1.1%) and the lowest in Rapide”s group with 7 cases (9%). Conclusions. Our study showed different results to the reported literature suggesting that each closure method has its own advantages and disadvantages. Quill is quick, knotless and absorbable but on the other side it is significantly more expensive than other alternatives and it is associated with the highest complication rates. On the other hand Rapide is cheap absorbable alternative with the lowest percentage of wound problems but on the negative side it is time consuming. Finally staples method is the quickest, relatively cheap and rarely associated with wound dehiscence but it is not absorbable which might cause inconvenience to patients

Purpose: Surgical staples are routine in closure of surgical incisions. Staples allow for expeditious closure and removal compared to suture materials. Concern exists, however, in obtaining an MRI scan when staples are present. The study analyzes common issues related to MRI scanning in the presence of surgical staples. Method: Thirty pig feet had one-inch surgical incisions made and repaired with five standard stainless steel surgical staples. Two parameters were analyzed: temperature change on the skin surface and staples displacement. Once placed, each skin staple position was marked for later referencing. A surface temperature laser device (Fluke 62 Mini) recorded pre-scan skin surface temperature. A 35-minute MRI scan was performed using a 1.5 Tesla magnet with a standard knee coil for each of the pig feet in an MRI suite at ambient room temperature. Immediately afterwards, the skin surface temperature was recorded and distance measurements were made in relation to the pen markings. A paired T-test was utilized to analyze the pre and post-scan data. Results: The mean temperature before the scans was 16.45 degrees Celsius with a standard deviation of 0.7 degrees. The median pre-scan temperature was 16.4 degrees. The minimum temperature was 14.6 degrees and maximum was 18.2 degrees. After scanning, the mean temperature was 16.02 degrees Celsius with a standard deviation of 0.63 degrees. The median post-scan temperature was 15.8 degrees. The minimum temperature was 15.0 and maximum temperature 17.6 degrees. The skin surface temperature showed a significant drop of 0.43 degrees Celsius (p=0.001). No change was recorded in staple position for any of the thirty pig feet pre-scan compared to post-scan. Conclusion: Occasionally, patients require MRI scans after having surgery where staples have been used to repair the incision(s). Concern exists over heat generation or movement of the staples during the magnetic process. This study demonstrated no recordable increase in skin surface temperature or displacement of staple position after a standard extremity MRI scan. Based on the findings of this study, MRI scanning in the presence of surgical staples appears safe

Introduction. Skin closure methods are various in total knee arthroplasty (TKA). Subcuticular skin closure techniques, which do not require postoperative stitch removal, are considered to be useful for excellent cosmesis and patients' satisfaction. Basically, subcuticular skin closure provides the tightness and water-tight seal, which leads to loss of postoperative normal physiologic drainage. As a routine wound closure, we performed the subcuticular skin closure with use of absorbable sutures or barbed sutures without staples. According to some previous reports, subcuticular skin closure using barbed sutures resulted in worse clinical outcomes, comparing with conventional skin staples. However, little attention has been paid to the differences between conventional absorbable and barbed sutures in both capsular and subcuticular skin closures. Our purpose was to investigate the efficacy and safety of the barbed suture, comparing to conventional absorbable sutures in TKA. Methods. A total of 81 knees in 75 patients (60 females and 15 males) were enrolled in the current investigation. Mean age was 73 (58–89) years old. All the subjects underwent unilateral or staged bilateral TKA using Balanced Knee System, posterior stabilized design (Ortho Development, Draper, UT). All knees were divided into two groups, as presented in Table 1. In conventional group, capsule was repaired using interrupted number 1 braided absorbable sutures, followed by closure of subdermal layer using a 3-0 monofilament absorbable suture with inverted interrupted knots. Thereafter, subcuticular skin closure was done using 4-0 monofilament absorbable suture, followed by adhesive tape. On the other hand, in barbed suture group, 1-0 and 4-0 unidirectional barbed suture (V-Loc, Covidien, Mansfield, Massachusetts) was used for capsule and subcuticular skin closure, respectively. Drains were removed on postoperative day 2. We evaluated closure time from capsule to skin, range of motion (ROM), Hollander Wound Evaluation Score (HWES: maximum score 6/6), and complications. Postoperative ROM and HWES were evaluated on postoperative day 14. As a statistical analysis, the data was compared between groups using Mann-Whitney U-test and Fisher exact probability test. P-values of < 0.05 were considered as significant. Results. 20 knees were allocated to conventional group and 61 knees were allocated to barbed suture group. Preoperative patients' demographics were seen in Table 2. No significant differences were found between groups preoperatively. In terms of clinical results, surgical closure time was significantly fast in barbed suture group, while postoperative range of motion and HWES were not significantly different between groups. In each group, wound related complication was not found. Discussion. According to previous reports, V-Loc provided worse clinical outcomes in wound related complications. However, in the current investigation, barbed suture was safe in wound cosmesis and effective in surgical closure time, comparing to conventional closure. We considered that barbed suture would be safe and effective as a closure method in TKA

Introduction. Joint reconstruction remains a successful and popular surgery with advances in approaches, implants and techniques continually forthcoming. Various methods of skin closure exist to address issues in efficiency, aesthetics, and barrier to infection. While subcuticular skin closure techniques offer an aesthetic advantage to conventional skin stapling, no measurable differences have been reported. Furthermore, newer barbed sutures, such as the V-loc absorbable suture, theoretically distribute tension evenly through the wound and help decrease knot-related complications. To our knowledge, no literature exists on the rate of wound complications in joint arthroplasty with the use of V-loc suture for skin closure. We hypothesize that despite theoretical gains, skin closure with a V-loc (Covidien, Mansfield, MA) absorbable suture should be performed with caution. Methods & Materials. A retrospective chart review was conducted of 278 consecutive primary joint reconstruction cases performed by a single surgeon in 12 months from July 2009 through June 2010. Pre-operative history & physical reports were evaluated for co-morbidities (i.e diabetes mellitus), smoking status and body mass index (BMI). Operative dictations by the attending surgeon provided information on the surgical procedure, use of drain, wound closure technique and type of suture/staple used for skin closure. Skin was closed by the primary surgeon and his chief resident. Wounds were closed via staple gun or subcuticular stitch (3-0 Biosyn vs V-Loc) in a consecutive manner, depending on the surgeon's preference in that period. Post-operative clinic notes were reviewed to determine the occurrence of wound complications, issuance of antibiotic prescriptions, or return to the operating room. The cohort consisted of 106 males and 161 females at an average age of 63 years (range: 18–92). Overall, there were 153 procedures at the knee (including TKA, uni-compartmental arthroplasty, patello-femoral arthroplasty) and 125 procedures at the hip (including THA and hemi-arthroplasty). Results. In review of 278 consecutive primary joint reconstruction cases, there were 17 (6.1%) post-operative wound complications noted, including cellulitis, stitch abscesses, wound dehiscence, and deeper infections requiring OR irrigation and debridement. In 181 cases, staples were used for skin closure; in these cases, seven wound complications were noted (7/181, 3.9%). In 49 cases closed via a subcuticular Biosyn suture there were 4 wound complications noted (4/49, 8.1%). Six wound complications occurred in cases closed with a V-loc suture (6/45, 13.3%). Discussion. Aesthetics and efficiency often are the driving forces of innovation. We present the rate of wound complications in various superficial wound closure methods, including the V-loc, an innovative absorbable barbed suture. Based on our clinical experience, we promote consideration of wound and infectious complications when choosing a method of skin closure in joint reconstruction procedures

Aims

The Birmingham Hip Resurfacing (BHR) was introduced in 1997 to address the needs of young active patients using a historically proven large-diameter metal-on-metal (MoM) bearing. A single designer surgeon’s consecutive series of 130 patients (144 hips) was previously reported at five and ten years, reporting three and ten failures, respectively. The aim of this study was to extend the follow-up of this original cohort at 25 years.

Aims

Periprosthetic joint infections (PJIs) are rare, but represent a great burden for the patient. In addition, the incidence of methicillin-resistant Staphylococcus aureus (MRSA) is increasing. The aim of this rat experiment was therefore to compare the antibiotics commonly used in the treatment of PJIs caused by MRSA.

Objectives

Wound complications are reported in up to 10% hip and knee arthroplasties and there is a proven association between wound complications and deep prosthetic infections. In this randomised controlled trial (RCT) we explore the potential benefits of a portable, single use, incisional negative pressure wound therapy dressing (iNPWTd) on wound exudate, length of stay (LOS), wound complications, dressing changes and cost-effectiveness following total hip and knee arthroplasties.

We live in troubled times. Increased opposition reliance on explosive devices, the widespread use of individual and vehicular body armour, and the improved survival of combat casualties have created many complex musculoskeletal injuries in the wars in Iraq and Afghanistan. Explosive mechanisms of injury account for 75% of all musculoskeletal combat casualties. Throughout all the echelons of care medical staff practice consistent treatment strategies of damage control orthopaedics including tourniquets, antibiotics, external fixation, selective amputations and vacuum-assisted closure. Complications, particularly infection and heterotopic ossification, remain frequent, and re-operations are common. Meanwhile, non-combat musculoskeletal casualties are three times more frequent than those derived from combat and account for nearly 50% of all musculoskeletal casualties requiring evacuation from the combat zone.

Introduction

Negative pressure wound therapy (NPWT) and vessel loop assisted closure are two common methods used to assist with the closure of fasciotomy wounds. This retrospective review compares these two methods using a primary outcome measurement of skin graft requirement.

We prospectively randomised 78 patients into two groups, ‘drains’ or ‘no drains’ to assess the effectiveness of suction drains in reducing haematoma and effusion in the joint and its effect on wound healing after total knee replacement. Ultrasound was used to measure the formation of haematoma and effusion on the fourth post-operative day. This was a semi-quantitative assessment of volume estimation. There was no difference in the mean effusion between the groups (5.91 mm in the drain group versus 6.08 mm in the no-drain, p = 0.82). The mean amount of haematoma in the no-drain group was greater (11.07 mm versus 8.41 mm, p = 0.03). However, this was not clinically significant judged by the lack of difference in the mean reduction in the post-operative haemoglobin between the groups (drain group 3.4 g/dl; no-drain group 3.0 g/dl, p = 0.38). There were no cases of wound infection or problems with wound healing at six weeks in any patient.

Our findings indicate that drains do not reduce joint effusion but do reduce haematoma formation. They have no effect on wound healing.

Patients considered suitable for total hip resurfacing arthroplasty often have bilateral disease. The peri-operative complications, transfusion requirements, hospital stay, outcome and costs in patients undergoing one-stage bilateral total hip resurfacing were compared with a group of patients undergoing a two-stage procedure. A total of 92 patients were included in the study, of which 37 (40%) had a one-stage and 55 (60%) had a two-stage resurfacing. There were no significant differences in age, gender, or American Society of Anaesthesiologists grade between the groups (p = 0.31, p = 0.23, p = 0.13, respectively). There were three systemic complications in the one-stage group (8.1%) and one in the two-stage group (1.8% of patients; 0.9% of procedures). There was no significant difference in the complication rate (p = 0.72) or the transfusion requirements (p = 0.32) between the two groups. The one-stage group had a reduced total hospital stay of five days (95% confidence interval 4.0 to 6.9; p < 0.001), reduced length of time to completion of all surgery of five months (95% confidence interval 2.6 to 8.3; p < 0.001), and the reduced cost was 35% less than that of a two-stage procedure. However, the total anaesthetic time was significantly longer for the one-stage group (p < 0.001; 95% confidence interval 31 to 52).

This study demonstrates that consideration should be given to one-stage surgery for patients with bilateral symptomatic disease suitable for metal-on-metal hip resurfacing. A one-stage procedure appears to have benefits for both the patient and the hospital without additional complications.

Limb lengthening by callus distraction and external fixation has a high rate of complications. We describe our experience using an intramedullary nail (Fitbone) which contains a motorised and programmable sliding mechanism for limb lengthening and bone transport. Between 2001 and 2004 we lengthened 13 femora and 11 tibiae in ten patients (seven men and three women) with a mean age of 32 years (21 to 47) using this nail. The indications for operation were short stature in six patients and developmental or acquired disorders in the rest.

The mean lengthening achieved was 40 mm (27 to 60). The mean length of stay in hospital was seven days (5 to 9). The mean healing index was 35 days/cm (18.8 to 70.9). There were no cases of implant-related infection or malunion.

We compared the safety and outcome of one-stage bilateral total hip arthroplasty with those of a two-stage procedure during different admissions in a prospective, randomised controlled trial in an Asian population. Of 168 patients included in the study, 83 had a single- and 85 a two-stage procedure. Most of the patients (59.9%) suffered from inflammatory arthritis.

The intra-operative complications, early systemic complications, the operating time, positioning of the components, the functional score, restoration of limb length and survival rates at 96 months were similar in the two groups. The total estimated blood loss was significantly lower in patients undergoing a one-stage procedure than in patients who had a two-stage procedure, but the transfusion requirements were significantly higher in the former group (p = 0.001). The hospital stay was significantly shorter in the one-stage group, 7.25 days (sd 1.30; 5 to 20) compared with 10 days (sd 1.65; 8 to 24) in the two-stage group (p = 0.023). We believe that a one-stage procedure is safe and appropriate in our population.
