A three-year-old intact female Great Pyrenees underwent total knee replacement for the treatment of osteoarthritis. The dog contracted septic arthritis 10 weeks following the procedure. Treatments including implant subtraction, debridement of tissue, and insertion of bone cement with antibiotics into the joint space were completed in the joint cavity. A temporary external skeletal fixator was used to stabilise the joint for four weeks. A second attempt at total knee replacement failed due to severe muscle contracture and bone loss. Therefore, it was decided to perform arthrodesis as a salvage procedure. At the 17 month follow-up examination, the patient was able to use the limb while standing and at all gait speeds. Based on these findings, two-stage arthrodesis can be a viable salvage procedure for infected total knee replacements.

Patella Tracking

Rotating platform total knee replacement implants have been marketed to allow more precise approximation of normal knee kinematics and enhance patella tracking. At liberty of rotation, the distinct mobile polyethylene insert design does have its pitfalls in spite of purported merits. We report a case of lateral knee pain following rotating platform total knee replacement, attributable to iliotibial band impingement by the rotating polyethylene insert. Prompt treatment via arthroscopic release circumvented a traumatic and costly revision procedure.

♦ Understanding the reason for failure of the original knee replacement is crucial prior to revision♦ The surgery should be a revision and not a repeat of the failed arthroplasty♦ There are eight reasons for failure of original knee replacements which should each be approached individually♦ Unexplained pain relating to a knee replacement requires further investigation before revision surgery can occur♦ Successful revision surgery is performed in three steps – preparation of a tibial surface, the knee in flexion and the knee in extension

Abstract Total knee replacement has become an accepted treatment for diseased and damaged joints with over 150,000 surgeries performed annually in the United States alone. The popularity of knee replacement stems from the excellent clinical results, which in some reported series exceeded ninety percent at twenty years follow-up [1]. The high level of clinical success in elderly populations has spurred surgeons to extend the indications to younger patients; today, about a third of total knee replacements are implanted in individuals under sixty-five years of age.

Posterior Direction

Prosthetic total knee replacements rarely dislocate. When dislocation does occur, it is usually in a posterior direction in association with a posterior stabilised, cruciate-sacrificing prosthesis. Neurovascular injury is unusual. In this report, we describe a case of anterior dislocation of a cruciate-retaining total knee replacement in a 67-year-old woman. The dislocation occurred in the absence of overt trauma and resulted in severe neurovascular injury.

Abstract Background Many patients experience bilateral knee osteoarthritis and require bilateral total knee replacement (TKR). Same-stage, bilateral TKR is proposed to be a cost-effective and safe solution compared to two-stage, but conflicting results in the literature are reported. We aim to compare the costs, safety, and rehabilitation performance of patients in same-stage versus two-stage, bilateral TKR with our centre’s perioperative protocol. Materials and methods We retrospectively reviewed 175 patients (95 same-stage, 80 two-stage) who had undergone bilateral TKR in our centre. Patient selection for same-stage, bilateral TKR was strictly protocol-driven and required fulfilment of all criteria, including age < 75 years, American Society of Anesthesiologists (ASA) grade 1 or 2, body mass index (BMI) < 40, and having non-complex arthritis. All patients followed a standardised pre-operative, intra-operative, and post-operative Enhanced Recovery After Surgery (ERAS) protocol. The cost, safety profiles, and rehabilitation outcomes were compared between the same-stage and two-stage groups. Results The same-stage, bilateral TKR reduced the length of hospital stays by 5.71 days per patient, decreased the operation time by 27.4 min, saved 3.34 (18.6%) physiotherapy sessions, and 3.78 (51.5%) occupational therapy sessions. The same-stage group experienced a higher haemoglobin drop but no significant difference in transfusion percentage, transfusion volume, complication rate, and readmission rate. The two-stage subgroup with anaesthetic risk, age, and BMI similar to the same-stage group showed the same results. Same-stage, bilateral TKR patients experienced no significant difference in final post-operative pain levels and rehabilitation outcomes as two-stage TKR patients. Conclusion This study showed that same-stage, bilateral TKR can reduce costs, with similar safety profiles and rehabilitation outcomes compared to the two-stage, bilateral TKR.

We analyzed the kinematics of two rotating platform total knee replacement designs using KneeSIM, a commercially available computer code (LifeModeler, San Clemente, CA) in which we could manipulate the location of the axis of rotation of the rotating bearing.
