Traumatic anterior knee dislocation after total knee arthroplasty.

ABSTRACT: This article describes a traumatic complete anterior knee dislocation of a previously well-functioning total knee arthroplasty. A thorough physical examination with appropriate radiographic imaging study is required for proper evaluation and treatment of this injury, as it is often associated with neurovascular injury and subsequent global instability of the injured knee is likely.

Rare Case of Traumatic Anterior Knee Dislocation of Total Knee Arthroplasty With a Serious Neurovascular Injury.

Project description:Traumatic anterior dislocation of a total knee arthroplasty (TKA) is an extremely rare occurrence. There are only a few known cases of this type of dislocation which discuss the high risk of a neurovascular complication. This article describes a traumatic anterior dislocation of the TKA with a severe vascular lesion in a 75-year-old severely comorbid patient. Further complications led to the development of a compartment syndrome. Despite the repeated effort in performing a well-functioning anastomosis of the popliteal artery tear by the vascular surgeon, reperfusion of the lower extremity was not effective. Furthermore, multiorgan system failure due to the reperfusion syndrome evolved. This led to an above-knee amputation as a lifesaving procedure. Despite thorough intensive care therapy, the patient did not survive this complication. Presently there are no reported cases with such severe complications after the luxation of a previously well-functioning TKA leading to the death of the patient.

Traumatic Lateral Knee Dislocation of a Well-Functioning Total Knee Arthroplasty: A Case of Medial Collateral Ligament Rupture.

Project description:Tibiofemoral dislocation can be a devastating complication after total knee arthroplasty. Much of the literature on tibiofemoral dislocations state they result from iatrogenic causes, with a very limited number of case reports on traumatic dislocation. Most of the time, these cases will require surgical revision and increased constraint to treat the inherent instability. In addition, collateral ligament disruption increases the complexity of the treatment algorithm for these patients. We report the case of a lateral tibiofemoral total knee arthroplasty dislocation with associated medial collateral ligament injury treated successfully without surgical interventions.

Total Knee Arthroplasty as the Primary Surgical Treatment After Knee Dislocation.

Project description:Traumatic knee dislocation (KD) is a rare but serious injury, and a missed diagnosis or incorrect treatment can be limb-threatening due to a significant risk of neurovascular injury. The mechanism of injury is often high-energy trauma, but there is a rising tendency of KD after low-energy trauma in the obese patient. KD often results in multiligament injury which can be a complicated surgical task with long recovery time, especially in older patients. This report presents 4 cases where patients older than 50 years with traumatic KD have been treated with a total knee arthroplasty of revision type as an alternative to multiligament reconstruction.

Total knee arthroplasty for treatment of osteoarthritis with prolonged patellar dislocation.

Project description:Prolonged dislocation of the patella is a rare condition and is often related to severe osteoarthritis (OA) of the femorotibial (FT) joint. For this condition's treatment, numerous surgical techniques using total knee arthroplasty (TKA) have been published. To the best of our knowledge, this case report is the first description of the use of lateral release alone to treat recurrent patellar subluxation with TKA. An interesting point in this case is that the patient had a good recovery after TKA in spite of quite a long-term (a duration of almost 55 years) dislocation of her patella and development of secondary OA. We describe a case that we treated by TKA for FT-OA with a prolonged patellar dislocation. We were able to obtain good patellar reduction without additional surgery by performing adequate lateral release of the patellar retinaculum. This clinical case indicates the usefulness of lateral patellar retinaculum release for obtaining stable patellar tracking in TKA for FT-OA with remaining lateral patellar dislocation.

Posterior dislocation of a constrained total knee arthroplasty: A case report.

Project description:IntroductionDislocation of the knee after primary total knee arthroplasty is rare in a posterior stabilized knee and extremely rare in a constrained total knee arthroplasty. Constrained total knee prostheses are used for severe knee deformities and to provide stable and mobile knees.Presentation of caseIn this case, we describe a dislocation of a primary constrained total knee arthroplasty using the Genesis II (Smith & Nephew, Memphis Tennessee, USA) prosthesis. Without any significant trauma, the constrained insert dislocated fifteen months after surgery and revision surgery with a bigger insert was needed. Surgical error may have been the cause of dislocation, but we were unable to establish a clear reason behind this dislocation.DiscussionKnee dislocation after TKA is rare but easily overlooked and can lead to serious complications and permanent disability. This system should provide stable and mobile knees to correct collateral ligament laxity.ConclusionHere, we report the first case, to our knowledge, of dislocation with a constrained prosthesis without any history of trauma.

Expression data from total knee arthroplasty patients

Project description:Ischaemic preconditioning is a method of protecting tissue against ischaemia-reperfusion injury. It is an innate protective mechanism that increases a tissue's tolerance to prolonged ischaemia when it is first subjected to short burst of ischaemia and reperfusion. It is thought to provide this protection by increasing the tissue's tolerance to ischaemia, therby reducing oxidative stress, inflammation and apoptosis in the preconditioned tissue. We used microarrays to investigate the genomic response induced by ischaemic preconditioning in muscle biopsies taken from the operative leg of total knee arthroplasty patients in order to gain insight into the ischaemic preconditioning mechanism. Patients undergoing primary knee arthroplasty were randomised to control and treatment (ischaemic preconditioning) groups. Patients in the treatment group received a preconditioning stimulus immediately prior to surgery. The ischaemic preconditioning stimulus consisted of three five-minute periods of tourniquet insufflation on the lower operative limb, interrupted by five minute periods of reperfusion. All patients had a tourniquet applied to the lower limb after the administration of spinal anaesthesia, as per normal protocol for knee arthroplasty surgery. Muscle biopsies were taken from the quadriceps muscle of the operative knee at the immediate onset of surgery (T0) and at 1 hour into surgery (T1). Total RNA was extracted from biospies of four control and four treatment patients and hybridised to the Affymetrix Human U133 2.0 chip.

Knee-Spanning External Fixation for Recurrent Traumatic Anterior Prosthetic Knee Dislocation With Associated Vascular Injury.

Project description:Traumatic anterior prosthetic knee dislocation after total knee arthroplasty is a rare event. We report the case of an 88-year-old female who presented with right traumatic anterior knee dislocation and concurrent popliteal artery injury requiring an emergent bypass graft. Postoperatively, the patient had redislocated her prosthetic knee, requiring urgent re-reduction and stabilization with an external fixator. We review her case, as well as additional reported cases of anterior knee dislocation. We also review the clinical considerations surrounding arterial injury, vascular bypass, and external fixation as a proposed management in unstable cases refractory to bracing.

Total knee arthroplasty after anterior cruciate ligament reconstruction: a narrative review.

Project description:Background and objectiveKnee replacement following anterior cruciate ligament (ACL) reconstruction can be demanding due to altered anatomy, soft tissue scars, bone loss, extensor mechanism complications, and knee instability. This narrative review summarizes the strategies and approaches to managing operative challenges in total knee arthroplasty (TKA) following ACL reconstruction.MethodsStudies reporting outcomes of patients who underwent TKA after ACL reconstruction were retrieved and assessed to be included in this review that synthesizes the available evidence highlighting the pitfalls encountered during surgery, the intraoperative challenges posed by ligament balancing and exposure, and the leading role of modular and retained implants.Key content and findingsTKA following ACL reconstruction has a high rate of intra-operative complications such as instability, bone loss, difficult exposure and demanding soft tissue balancing, representing a revision surgery rather than routine primary knee arthroplasty and a revision-oriented skill set and modular components are recommended to significantly optimize both surgical strategy and patient outcomes. With a rising incidence of ACL injuries and growing reconstructions, anticipating an increase in TKA procedures, this review aims to provide a call for rethinking clinical approaches to ensure effective and patient-centric care.ConclusionsThis narrative review seems to indicate that TKA after ACL reconstruction should be considered as revision surgery and modular components should be used. However, future prospective and high-quality studies are required to better clarify risk factors and give strong recommendations for this complex surgery.

Primary Complex Total Hip Arthroplasty in Neglected Anterior Hip Dislocation With Comminuted Pertrochanteric Femur Fracture.

Project description:Neglected anterior hip dislocation combined with comminuted pertrochanteric ipsilateral fracture of the femur is rare, with few reports in the literature. The present report describes the case of a 7-month-old neglected anterior hip dislocation with a pertrochanteric femoral fracture in a 45-year-old male patient. The patient was treated with total hip arthroplasty with proximal femoral reconstruction. The 2-year follow-up showed good clinical and radiological outcomes with a painless and mobile hip joint. The Harris-Hip score improved from 10 (preoperatively) to 89 (postoperatively) after 2 years. The patient was satisfied with the intervention and showed minimal lurch with ambulation with no leg-length discrepancy. However, long-term results from periodic follow-up are warranted.
