Abstract
INTRODUCTION Options for soft tissue coverage in revision total knee arthroplasty (rTKA) range from primary wound closure to complex muscle flap reconstructions. The purpose of this study was to investigate the institutional experience of wound coverage options for complex soft tissue defects in rTKA. MATERIALS AND METHODS 77 patients undergoing rTKA with complex wound closure by a single plastic surgeon were retrospectively reviewed. The average follow-up was 30.1 months. In 18 (23.4%) patients, an intraoperative decision for primary closure was made. Fifty-nine patients (76.6%) received either a local fasciocutaneous (N = 18), a medial gastrocnemius (N = 37), a free latissimus dorsi (N = 3) or a lateral gastrocnemius flap (N = 1). Revision-free survival and complication rates were assessed and risk factors were analyzed with Cox-regression analysis. RESULTS Medial gastrocnemius flaps had significant lower cumulative revision-free survival rates than local fasciocutaneous flaps (P = 0.021) and primary closures (P < 0.001) (42.5% vs. 71.5% vs. 100%,respectively). Comparing the most common complex closure procedures medial gastrocnemius flaps had the highest rate of prolonged wound healing (29.7%) and infection/reinfection (40.5%). Infection-associated flap procedures had significant lower cumulative revision-free survival rates (30.5%) than non-infection associated flap procedures (62.8%,P = 0.047). A history of more than two prior surgeries (HR = 6.11,P < 0.001) and an age ≥ 65 years (HR = 0.30,P = 0.018) significantly increased the risk of revision. CONCLUSIONS The results of this study indicate that primary closure -if possible- should be preferred to early proactive muscle flap coverage. Even in the hands of an experienced plastic surgeon muscle flaps have high revision and complication rates. The study highlights the need to clarify flap indications and to investigate alternative approaches.

Abstract
INTRODUCTION Soft tissue defects are a devastating complication of prosthetic joint infections (PJI) after total knee arthroplasty (TKA). Rotational flaps are commonly utilized to address these defects with variable reports of success. This study aimed to identify predictors of poor outcomes in rotational muscle flap placement after prosthetic knee infections. The authors hypothesized that outcomes may vary based on infecting pathogen and treatment characteristics. METHODS 44 cases of rotational muscle flaps for prosthetic knee infection were retrospectively evaluated at a tertiary referral hospital from 2007 to 2020. Muscle flap types included 39 medial and four lateral gastrocnemius, and one anterior tibialis. Minimum follow-up was 1 year (median: 3.4 years). Primary outcome was flap-related complications. Secondary outcomes included recurrent infection requiring additional surgery, final joint outcomes, and mortality. RESULTS One-year complication-free flap survivorship was 83.9%, recurrent infection-free survivorship was 65.7%, and amputation-free survivorship was 79%. Multivariable cox regression revealed that rheumatoid arthritis diagnosis (HR: 3.4; p = .028) and methicillin-resistant Staphylococcus aureus-positive culture (HR: 4.0; p = .040) had increased risk, while Coagulase-negative Staphylococcus infections had reduced risk for recurrent or persistent infection (HR: 0.2; p = .023). Final joint outcome was retained TKA implant in 18 (40.9%), amputation in 15 (34.1%) patients, and definitive treatment with articulating spacer in 10 (22.7%). 5-years survivorship from death was 71.4%. CONCLUSION Rotational muscle flaps for soft tissue coverage of the knee are often performed in limb salvage situations with poor survivorship from flap complications, reinfections, and amputation. When considering surgical options for limb salvage, patients should be counseled on these risks.

Abstract
BACKGROUND Soft tissue defects or periprosthetic infections after total knee arthroplasty (TKA) are severe complications that may lead to loss of the arthroplasty or the limb. Reconstructions with medial gastrocnemius flaps (MGF) are occasionally used to provide soft tissue coverage around the knee. AIMS The study aimed to establish the rate of implant survivorship after MGF reconstruction for soft tissue coverage in the treatment of exposed or infected TKA and to establish functional outcome. METHODS A retrospective analysis was performed on all patients who received soft tissue coverage with an MGF of an exposed or infected TKA between 2000 and 2017 at the Department of Hand and Plastic Surgery at Umeå University Hospital. The outcomes were implant survivorship and patient-reported outcome measures (PROMs) using the five-level EQ-5D version and The Knee Injury and Osteoarthritis Outcome Score. RESULTS Forty-seven patients (mean age = 67 years, 30 women) were included. The mean time between flap coverage and follow-up was 6.7 (±3.4) years. Implant survivorship was observed in 28 of 47 (59.6%) patients at follow-up. Flap failure was rare, with only 3 of 47 (6.4%) cases. Of the 20 patients who answered the PROMs, 10 of 20 experienced moderate to severe pain or discomfort. CONCLUSIONS Due to unfavorable underlying conditions, MGF reconstruction after TKA is often associated with a compromised functional outcome. Because donor site morbidity is limited and flap failure is unusual, the procedure can be considered prophylactically in a small subset of patients with risk factors to prevent soft tissue defects and periprosthetic joint infection.

Abstract
BACKGROUND Prosthetic joint infection (PJI) is a challenging complication of knee arthroplasty, which can require amputation in severe cases. This study analyzes the utility of flap reconstruction in PJIs requiring hardware removal and extensive soft tissue debridement. METHODS This was a retrospective analysis of patients who were treated according to a multistage extremity salvage protocol between 2018 and 2022. The protocol involved at least 3 planned surgeries including (1) hardware removal with antibiotic spacer placement and soft tissue debridement, (2) spacer exchange with flap coverage, and (3) hardware reimplantation with simultaneous or delayed extensor mechanism reconstruction. All patients had large periprosthetic tissue defects that would necessitate an amputation if not reconstructed. Primary outcomes were extremity salvage and successful defect coverage. RESULTS Fifty-two patients (25 female) underwent 62 reconstructions (52 primary, 10 salvage). Flap techniques included pedicled muscular (n = 32), fasciocutaneous (n = 4), combined muscular and fasciocutaneous (n = 2), and free flaps (n = 24). Overall rate of successful defect coverage was 95% (98% in primary and 80% in salvage reconstructions). At a median follow-up of 11 months, 41 patients completed the treatment protocol with a 68% (n = 28) extremity salvage rate (reimplantation arthroplasty, n = 15; permanent knee fusion, n = 13). On the multivariate model including demographic factors, defect size, and flap type, no single factor independently predicted limb salvage. CONCLUSIONS Alongside intensive orthopedic surgical treatment, flap coverage may aid in extremity salvage in severe knee PJIs by reestablishing healthy soft tissue coverage and allowing reimplantation arthroplasty. We recommend a multispecialty approach including plastic surgeons for this challenging condition.

Abstract
BACKGROUND Wound complications following revision TKA can be catastrophic and can compromise joint and even limb. The purpose of this study was to determine the prevalence of superficial wound complications requiring return to the OR in revision TKA, rates of subsequent deep infection, factors that increase the risk of superficial wound complications, and the outcomes of revision TKA following development of superficial wound complications. METHODS We retrospectively reviewed 585 consecutive TKA revisions with at least two years follow-up, including 399 aseptic revisions and 186 reimplantations. Superficial wound complications without deep infection requiring return to the OR within 120 days were compared to controls. RESULTS Fourteen patients following revision TKA (2.4%) required return to the OR for a wound complication, including 7 of 399 (1.8%) patients who underwent aseptic revision TKA and 7 of 186 (3.8%) patients undergoing reimplantation TKA (p = 0.139). Aseptic revisions with wound complications were more likely to develop subsequent deep infection (HR 10.04, CI 2.24-45.03, p = 0.003), but this did not hold true for reimplantations (HR 1.17, CI 0.28-4.91, p = 0.829). Risk factors for wound complication included atrial fibrillation when all patients were combined (RR 3.98, CI 1.15-13.72, p = 0.029), connective tissue disease in the aseptic revision group (RR 7.1, CI 1.1-44.7, p = 0.037), and a history of depression in the re-implantation group (RR 5.8, CI 1.1-31.5, p = 0.042).

Abstract
Different factors have to be considered and weighted in the treatment algorithm of lower extremity reconstruction. A combination of both clinicians' and patients' perspectives is necessary to provide a conclusive picture. Currently, there aren't any standardized and validated measurement data sets for lower extremity reconstructions. This makes it necessary to identify the relevant domains. We, therefore, performed a systematic review and metanalysis of outcome measurements and evaluated their ability to measure outcomes after lower extremity reconstruction. A systematic review and metanalysis according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' protocol were performed for studies reporting at least one structured outcome measurement of lower extremity reconstruction. Both Patient (PROMs)- and Clinician reported outcome measurements (CROMs)were analyzed. Of the 2827 identified articles, 102 were included in the final analysis. In total 86 outcome measurements were identified, 34 CROMs, 44 PROMs and 8 (9.3%) outcome measurements that have elements of both. Twenty-four measure functional outcome, 3 pain, 10 sensations and proprioception, 9 quality of life, 8 satisfaction with the result, 5 measure the aesthetic outcome, 6 contours and flap stability and 21 contain multidomain elements. A multitude of different outcome measurements is currently used in lower extremity reconstruction So far, no consensus has been reached on what to measure and how. Validation and standardization of both PROMs and CROMs in plastic surgery is needed to improve the outcome of our patients, better meet their needs and expectations and eventually optimize extremity reconstruction by enabling a direct comparison of studies' results.

Abstract
Background Flap reconstruction with perforator, fasciocutaneous, muscular, and/or free microvascular flaps is utilized to cover wound defects and improve vascularization and antibiotic/nutrient delivery. Flap use in revision procedures for total knee arthroplasty has been explored previously; however, current data are limited and studies comparing healing and complication rates between different flap types are lacking. Methods A literature review was performed using PubMed on 13 January 2022. Studies were included if they reported healing and complication rates for either gastrocnemius, rectus abdominis, latissimus dorsi, fasciocutaneous, chimeric, or gracilis flaps in the setting of revision total knee arthroplasty (TKA). Results The final cohort included gastrocnemius (n = 421, healing rate 73.8%, complication rate 59.9%), gracilis (n = 9, healing rate 93%, complication rate 55.6%), latissimus dorsi (n = 41, healing rate 67%, complication rate 46.3%), rectus abdominis (n = 3, healing rate 100%, complication rate 0%), fasciocutaneous (n = 78, healing rate 70%, complication rate 19.2%), and chimeric flaps (n = 4, healing rate 100%, complication rate 25%). There was no significant difference when comparing healing rates across flap types (p = 0.39). There was a significant difference when comparing complication rates across flap types (p < 0.0001), with a significant difference being noted between gastrocnemius and fasciocutaneous complication rates (p < 0.0001). All other comparisons between flap types by complication rate were not significantly different. Conclusions Gastrocnemius flaps are the workhorse flap in the setting of revision TKA, as evidenced by this review. Healing rates did not vary significantly across flap types, which suggests that determining the appropriate flap for coverage of soft-tissue defects in revision TKA should be driven by defect size and location as well as physician experience and patient tolerance.

Abstract
In the multiply operated on knee replacement, no one soft tissue procedure is vastly superior to another. The most extensive literature available is in relation to muscle flaps, which will continue to be the workhorse technique for orthopedic and plastic reconstructive surgeons for the foreseeable future. Closed incision negative pressure wound therapy may prove to be a superior method in time but further large-scale studies are required to expand our understanding of this technique. The continued use of a combination of these techniques, tailored to the specific patient, is likely to be the best approach to the multiply operated on knee into the future.

Abstract
Pathologic fractures secondary to metastatic disease are an increasingly prevalent problem. Such patients require multidisciplinary collaboration to optimize clinical outcomes. An established algorithm for clinical, laboratory, and radiographic work-up will ensure that each patient achieves the best outcome while avoiding catastrophic complications. Metastatic disease to the region of the knee is less commonly encountered than in other regions of the body, but it presents unique difficulties that merit discussion. Part one of this two-part article series will discuss the appropriate work-up of patients with suspected or impending pathologic fracture of the distal femur, highlight biopsy principles, address perioperative nonsurgical treatments that will optimize patient outcomes, and discuss available surgical treatment modalities.

Abstract
Soft tissue defect coverage has always been a challenge for the orthopaedic surgeon. Over the last decades the surgery of flaps has completely changed the prognosis for large defects. The purpose of this study is to retrospectively review our experience with the gastrocnemius muscle as pedicled local flaps for reconstruction of knee and upper third of the tibia soft tissue defects. Twenty-seven patients underwent reconstruction of soft tissue defects around the knee using pedicled gastrocnemius muscle flaps. There were eighteen men and nine women ranged in with a mean age of 50.3 years. Medial gastrocnemius was used in 21 cases, and lateral gastrocnemius in 5 cases. In one patient, soleus and medial gastrocnemius were transferred simultaneously. All but one had at the same time split thickness skin graft for coverage of the muscle. All muscle flaps transferred were successful. There were no complications and all flaps survived completely without vascular compromise, satisfactory coverage of the defect, and good primary wound healing. There has been no recurrence of osteomyelitis. The donor sites healed perfectly with no remarkable resultant functional disability. A mean follow-up of 4.4 years revealed acceptable cosmetic results with high patient satisfaction. Our results indicate that the gastrocnemius muscle transfer is a useful technique for coverage of soft tissue defects in the upper tibia and around the knee in our orthopaedic practice. It is a reliable option for the coverage of exposed bone, the filling up of deep cavities and the treatment of bone infection. The principal advantage of a muscle flap is to bring a real blood supply to the recipient site and to improve the trophicity of the surrounding tissues. The pedicled muscle flap is our preference for the management of soft tissue defects around the knee, when no other procedure, apart from free flap is suitable. The pedicle flap is easier, quicker and with less complications than a free flap. Orthopaedic surgery has gained much from the use of island flap, however, it requires knowledge of the vascular anatomy and its variations promoted through cadaveric dissections and flap dissection courses.

Abstract
BACKGROUND Free flap coverage in the setting of a total knee arthroplasty is rare. The purpose of the current study was to evaluate the outcome of patients who underwent a free flap to assist with soft-tissue coverage following a complex total knee arthroplasty. METHODS The authors used their institutional total joint registry to retrospectively review patients undergoing a free soft-tissue flap in the setting of complex primary and revision total knee arthroplasty. Among 29,069 primary and 6433 revision total knee arthroplasties from 1994 to 2017, eight (0.02 percent) required a free flap for wound coverage. This included three primary total knee arthroplasties (0.01 percent) for posttraumatic arthritis and five revision total knee arthroplasties (0.07 percent) in the setting of infection. Median follow-up was 4 years. RESULTS Free flaps included vertical rectus abdominis (n = 3), anterior lateral thigh (n = 2), latissimus (n = 2), and transverse rectus abdominis (n = 1). There were no total flap losses; however, one patient required additional skin grafting. Reoperation occurred in six patients, of which four were revisions of the total knee arthroplasty for infection (n = 2) and tibial component loosening (n = 2). One patient ultimately underwent transfemoral amputation for persistent infection. Following reconstruction, there was improvement in the median Knee Society Score (49 versus 82; p = 0.03) and total range of motion between preoperative and postoperative assessments (70 degrees versus 85 degrees; p = 0.14). CONCLUSION Free flap coverage in the setting of total knee arthroplasty was associated with a high rate of reoperation; however, the limb was able to be preserved in the majority of patients, with a reasonable functional outcome. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
PURPOSE Gastrocnemius flaps provide reliable reconstructive solutions to soft-tissue loss of the knee and proximal tibia following orthopedic procedures. While this technique has been used and studied, little is known about its prophylactic application. Single-stage and delayed approaches were compared with respect to the timing of débridement, complications, and relationship between microorganisms and complications. METHODS Gastrocnemius flaps for soft-tissue defects of the knee joint were retrospectively reviewed. Success of the flap procedure was defined as a healed soft-tissue envelope, no evidence of infection, a good blood supply to the flap, and adherence of the flap to its bed. Independent sample t test was used to compare the corresponding parameters (level of statistical significance was 0.05). RESULTS Of 43 flaps (43 patients), 18 were performed during a single-stage procedure along with the orthopedic procedure and 25 were delayed. Success of the single-stage (100%) and delayed flaps (88%) was not significantly different (p = 0.083). Complication rate did not differ significantly for single-stage (11%) and delayed flaps (24%) (p = 0.272). We were unable to establish a relationship between complications and microorganisms. CONCLUSION Results indicate both approaches are reliable. Single-stage gastrocnemius flaps may eliminate the need for a second surgery. LEVEL OF EVIDENCE Level III (Therapeutic, Retrospective cohort).

Abstract
BACKGROUND Soft tissue deficiency in total knee arthroplasty infection is a potentially devastating complication. Gastrocnemius muscle flaps can be used to address this problem. We aim at reporting survival rates of these reconstructions and identify risk factors for failure. METHODS A retrospective evaluation of all flaps performed at a single center between 2006 and 2019 was performed. Clinical and microbiological results were assessed in 43 cases after a median follow-up period of 53 months (25%-75% interquartile range 18-79). Function was assessed using the Oxford Knee Score. We analyzed the infection-free survival and identified risk factors using survival comparison and (non-)parametric testing. RESULTS Infection-free survival was 71% at 2 years and 63% at 5 years. The rate of subsequent amputation was 16% with a mortality rate of 26% during follow-up. Four patients did not undergo reimplantation and 11 patients received an arthrodesis implant. There were no failures of the flap itself. The Charlson Comorbidity index was the only relevant risk factor for reinfection. Coagulase-negative staphylococci were most common organisms identified. Postoperative function was limited with a mean Oxford Knee Score of 20. CONCLUSION Gastrocnemius flap coverage is a valid option for soft tissue reconstruction in periprosthetic infections to retain a functioning limb despite a high complication rate and the risk of subsequent amputation.

Abstract
BACKGROUND Treatment goals for pathologic fractures about the knee include pain relief and unrestricted weight bearing. In cases of condylar destruction, these fractures may not be amenable to internal fixation, and arthroplasty may be considered. The purpose of this study was to analyze the outcomes of knee arthroplasty for primary treatment of impending or pathologic fractures of the distal femur or proximal tibia. METHODS Fifteen (8 males and 7 females) patients, mean age 62 ± nine years, undergoing arthroplasty for management of a pathologic peri-articular distal femur (n = 11) or proximal tibia (n = 4) fracture between 2001 and 2017 were reviewed. Implants included tumour endoprostheses (n = 11) and rotating hinged total knees (n = 4). Pathology included metastatic disease (n = 14) and lymphoma (n = 1). Eight (53%) patients presented with a fracture while the remainder had large impending lesions. RESULTS Mean follow-up was 19 months. At final follow-up, 11 patients had died with overall five year survival of 33%. Two (13%) patients required re-operation; including wound irrigation and debridement (n = 1) and above knee amputation for local recurrence (n = 1). An additional two (13%) patients developed post-operative VTE. MSTS, KSS, and KSS-F scores improved from a mean 12 ± 16%, 30 ± 11, and 14 ± 24 pre-operatively to 69 ± 26%, 75 ± 16, and 67 ± 25 at final follow-up, respectively (P < 0.001). Thirteen (87%) patients had severe pain prior to surgery with no patients (0%, P < 0.001) reporting severe pain at last follow-up. CONCLUSION Knee arthroplasty provided improved function and full weight-bearing making it an effective treatment for pathologic periarticular fractures of the distal femur and proximal tibia.

Abstract
BACKGROUND Wound complications associated with soft tissue defects following total knee arthroplasty present challenges for the orthopedic surgeon. The scale of early complications include less morbid problems, such as quickly resolving drainage and small superficial eschars, to persistent drainage and full-thickness tissue necrosis, which may require advanced soft tissue coverage. METHODS This review outlines current wound management strategies and provides an algorithm to help guide treatment and clinical decision-making. CONCLUSION A surgeon's understanding of soft tissue coverage options is essential in protecting the knee prosthesis from a deep infection and to obtain an optimal functional outcome.
