Clinical follow-up studies have shown that approximately 5% of all patients who receive press-fit cobalt-chromium alloy femoral implants experience failure of the intramedullary stem component as a result of septic loosening or stem breakage. For stem breakage, stem diameter and the occurrence of infectious events were identified as risk factors. We began regularly utilizing the standard German press-fit endo-exo cast cobalt-chrome implant in 2009, but changed to the forged titanium version in 2014 (BADAL X, OTN Implants) because of the breakages associated with the former implant. No breakages have been reported since making the switch, and as such we currently still utilize the titanium implant. Current Commission Européenne-certified bone-anchored implants for transfemoral amputation include a screw-type stem and a press-fit stem. The revision technique demonstrated in the present article may apply to both types of implant system, but this video is limited to demonstrating the use of a press-fit implant. We describe the 3 stages of debridement, removal, and subsequent implantation of a bone-anchored prosthesis in a revision setting.</p><p><strong>Description: </strong>We perform this procedure in up to 3 stages, with 10 to 12 weeks between removal of the failed implant and implantation of the revision prosthesis. For stage 1, in case of mechanical failure, the broken remnants of the implant, which may dangle in the soft tissues, are removed. The stoma is debrided, after which spontaneous stoma healing is achieved. In cases of septic loosening, stage 1 includes removal of the implant by retrograde hammering, followed by multiple debridements with flexible reamers and jet lavage until negative cultures are obtained. In stage 2, the broken osseointegration implant is removed with use of a custom-made titanium water-cooled hollow drill. With the use of this drill, we have always been successful in removing the broken implant while maintaining sufficient bone stock for future implant revision. If the corer fails, a larger approach is needed to remove the implant. The corer drill should have a wall that is as thin but as robust as possible in order to avoid cortical perforation, and should be manufactured from a strong material in order to resist the usage against the implant. We utilized a steel corer when initially performing this procedure, which was frequently unsuccessful, necessitating a larger approach to remove the implant. We currently utilize a 3D-printed corer drill with integrated water-cooling system with greater success (Xilloc Medical). This corer is custom-made and needs about 6 weeks for designing and manufacturing. This tool is utilized in the present video article.

The ulnar nerve is identified and protected during the entire surgical procedure. In case of severe (>30°) and long-standing cubitus varus deformity, anterior transposition of the ulnar nerve is additionally performed to prevent nerve stretching after the deformity correction. A midline triceps-splitting approach is utilized along with subperiosteal dissection to expose the metaphyseodiaphyseal region of the distal humerus.

When avoiding the risks of cement use, a press-fit arthroplasty stem that has been implanted may not feel immediately stable, especially if the medullary canal size is in between standard stem diameters. To help surgeons improve fixation and avoid overstuffing the medullary canal, we present the matchstick autograft augmentation technique. The use of humeral autograft, analogous to impaction grafting in hip arthroplasty, has been reported to have promising short-term outcomes<sup>2,3</sup>. This technique of using humeral autograft material, dubbed matchstick autografts because of their shape and size, allows for optimization of humeral stem stability with the option of smaller cementless humeral implants.

The canal is sequentially broached with implant trials until the tactile feedback demonstrates axial and rotational stability. In cases in which tactile feedback during implantation demonstrates slight movement, the smaller implant size can be selected and augmented with matchstick autograft. An oscillating saw is utilized to cut the edges of the previously resected humeral head in order to expose the subchondral bone surface. Graft sticks about 20 mm in length and 1 to 3 mm in width are then fashioned. Humeral trials are then implanted with the matchstick grafts placed lengthwise alongside the humeral stem. Axial and rotational press-fit is again assessed. If adequate, the formal humeral implant is selected and implanted in position.

The fundamental principles include a strong initial biomechanical fixation, cuff footprint anatomy restoration, and maximization of biological factors to promote healing of the rotator cuff. Rotator cuff repair was originally performed as an open procedure, which allows for direct visualization of the tear and repair; however, open repair requires some level of deltoid splitting, which can potentially affect postoperative early mobilization. Single-row and double-row cuff repairs can both be performed arthroscopically. Proponents of the double-row procedure prefer that technique for its footprint restoration and stronger biomechanical fixation; however, the double-row procedure can result in overtensioning of the repair and can lead to medial-based rotator cuff failures. Proponents of the single-row procedure prefer that technique for its ease of operation, fewer implants, lower cost, and low repair tension; however, the single-row procedure fixes the tendon at a single point, limiting the repaired footprint, and can be associated with lower fixation strength.

A midline incision to the knee is made over the quadriceps tendon defect, exposing the distal quadriceps and proximal patella. Irrigation is utilized to evacuate the residual hematoma, and the distal quadriceps and proximal patella are debrided of degenerative tissue. When utilizing transosseous tunnels, a nonabsorbable suture is passed full-thickness through the medial or lateral half of the quadriceps tendon in a locked, running pattern (i.e., Krackow). A second nonabsorbable suture is passed full-thickness through the other half of the tendon. There should then be 4 loose strands at the distal quadriceps. The anatomic insertion of the quadriceps tendon is roughened with a sharp curet to expose fresh cancellous bone. Three parallel bone tunnels are created along the longitudinal axis of the patella. The knee is placed in full extension, with a bump under the heel in order to provide slight recurvatum at the knee and to allow for a properly tensioned repair.

Primary repair or reconstruction is selected, and an 8-0 or 9-0 nonabsorbable monofilament suture is utilized to anastomose the appropriate structures under magnification with use of a single or double stitch<sup>6</sup>. A tubular nerve conduit is placed prior to epineurial suturing, or a nerve conduit wrap is applied circumferentially around the repair site and augmented with a fibrin glue. The wound is then irrigated and closed in a standard fashion, as determined by the presence of any soft-tissue or structural injury.</p><p><strong>Alternatives: </strong>Alternatives to primary repair include the use of cond","PeriodicalId":44676,"journal":{"name":"JBJS Essential Surgical Techniques","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11392468/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TKA is one of the most commonly performed orthopaedic surgical procedures in the United States and is associated with substantial improvements in pain, function, and quality of life<sup>1-3</sup>. The procedure may be performed with cemented, cementless, or hybrid cemented and cementless components<sup>4,5</sup>. Cementless TKA utilizing contemporary implant designs has been demonstrated to have excellent long-term survival and outcomes in patients who are appropriately indicated for this procedure<sup>5-8</sup>. The preference of the senior author is to perform this procedure with use of a cruciate-retaining implant design when feasible, and according to the principles of mechanical alignment to guide osseous resection. It should be noted that nearly all recent studies on outcomes following cementless TKA utilize traditional mechanical alignment<sup>7-9</sup>. Alternative alignment strategies, such as gap balancing and kinematic alignment, have not been as well studied in cementless TKA; however, preliminary short-term studies suggest comparable survivorship with restricted kinematic alignment and gap balancing compared with mechanical alignment in patients undergoing cementless TKA<sup>10,11</sup>.</p><p><strong>Description: </strong>Our preferred surgical technique for cementless TKA begins with the patient in the supine position. A thigh tourniquet is applied, and a valgus post is set at the level of the tourniquet. A flexion pad is also placed at 90°, with a bar at 20°. After sterile skin preparation and draping, a time-out is conducted, and the tourniquet is raised. The surgeon makes a medial parapatellar incision, which begins from 1 cm medial to the medial edge of the patella, extending from the tibial tubercle to 2 fingers above the proximal pole of the patella, using a knife and with the knee at 90° of flexion. Scissors are then used to find the fat above the fascia and dissect distally in the same plane. A knife is used to perform a high vastus-splitting, medial parapatellar arthrotomy. Pickups and scissors are then used to perform a partial medial synovectomy, and electrocautery is used to perform a medial peel. As the procedure progresses further medial, the infrapatellar fat pad is excised, followed by the anterior femoral synovial tissue. The surgeon then cuts through the anterior cruciate ligament footprint and origin with the knee flexed before sawing through the tibial spines to decrease the height of the tibial bone block. To prepare the femur, a step drill is inserted into the femoral canal, and the intramedullary alignment guide is placed with the distal femoral cutting guide set to 5° of valgus. The distal femoral cutting guide is then pressed firmly against the distal femur, making sure that the medial side is touching bone, and threaded pins are ","PeriodicalId":44676,"journal":{"name":"JBJS Essential Surgical Techniques","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11392501/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
