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.

Return to regular sports activity was evaluated in a retrospective review of 160 patients who had undergone total knee replacement surgery by a single surgeon (208 knee replacements). Mean age of the patients was 68 years (range, 27 to 87) at surgery and 73 years (range, 33 to 91) at review at a mean follow-up of 5 years (range, 3 to 7). Seventy-nine patients regularly participated in sports, at least once per week, before surgery, and 51 patients regularly participated in sports after surgery. Only eight patients took up sports after surgery who were not regularly involved in sports in the year before surgery. Patients were more likely to return to low-impact activities such as bowls (29 of 32, or 91%) than to high-impact activities such as tennis (6 of 30, or 20% returned). Forty-three of 56 patients (77%) who had participated in regular exercise in the year before surgery returned to sports. Eighty patients did not participate in sports before surgery and 54 of these had coexisting disease that prevented sports. None of these patients returned to sports.

♦ 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

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 Aim In knee replacements, restoration of mechanical alignment is essential. Patients with extra-articular deformities (EAD) pose challenges in planning knee replacements. We present a method, based on our experience and review of literature on planning knee replacement surgery, in the presence of extra-articular coronal plane deformity of the tibia. Method Retrospective analysis was made of six patients with EAD of the tibia who underwent knee replacement at our centre. Mechanical axis of the tibia is considered and positioning of the tibia component is planned perpendicular to the mechanical axis of the tibia. The integrity of the collaterals determines the need for correction. Tibial resection >15mm from medial or lateral aspect of the tibia is an indication for corrective osteotomy prior to replacement surgery. The hip knee ankle angle (HKA) was noted. Pre-operative, post-operative clinical score, degree of constraints and post-operative complications were recorded. A post-operative long leg alignment radiograph was obtained. Result All patients had total knee replacement without correction of deformity. Adequate alignment of the limb and restoration of mechanical axis was achieved in all six patients without the need for correction of tibial deformity. All patients had improvement in their HKA angle and Oxford knee score. No re-operations were required, and no complications recorded. Conclusions Our study will help provide guidance on operative planning and decisions making for patients with extra-articular coronal plane tibial deformities.

INTRODUCTION The effect of primary total knee replacement on the employment status of 56 patients under 60 years of age was examined at a mean follow-up of 64 months. PATIENTS AND METHODS A total of 56 primary total knee replacements performed on patients under the age of 60 years by two surgeons between 1996 and 2003 were retrospectively assessed by postal questionnaire. Patients were selected from databases held at Holly House and Newham Hospital NHS Trust. RESULTS Overall, 97.5% of patients who were employed before their operation, returned to their previous work. However, in patients not working prior to total knee replacement none were employed after their operation. CONCLUSIONS Total knee replacement may be a valuable tool to help some patients to continue working but may not affect patients who are already unemployed.

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.
