BACKGROUND: Total knee arthroplasty (TKA) is one of the most common orthopaedic surgical procedures in the advanced stages of knee arthritis. OBJECTIVE: The purpose of this study was to define the sex differences in the Turkish population’s morphological measurements of the distal femoral and proximal tibial surfaces that form the knee joint and to compare their compatibility with conventional prosthetic implants commonly used in TKA for advanced-stage knee arthritis. METHODS: Anthropometric data for a total of 240 knees from 240 patients were measured using 3-dimensional computed tomography (3D CT). All morphological data were compared with the dimensions of four conventional knee prostheses commonly used in Turkey. RESULTS: A comparison of the four tibial components revealed that the majority of female proximal tibias matched with smaller-sized tibial components, whereas those of males matched the larger sizes. Comparing the morphological data with similar values for the four femoral components currently used in Turkey, we found that all the prostheses had similar values. CONCLUSION: The four conventional prosthetic brands included in this study matched the distal femoral dimensions of both sexes. On the other hand, we need smaller size tibial components for our female population.

Rotating-hinge knee implants are fully constrained knee prostheses commonly used for revision total knee arthroplasty. Nevertheless, rotating-hinge devices have been increasingly utilized in primary setting. Complications are inevitable in orthopedic surgery, however, implant breakage after RHK arthroplasty has been rarely described in medical literature. We present a rare case of 70-year-old Caucasian, male patient who suffered an atraumatic femoral stem breakage in a primary NexGen ® Rotating Hinge Knee (Zimmer-Biomet ® , Warsaw, IN, USA).

Abstract Total Knee Arthroplasty is one of the most commonly performed orthopedic procedures and it is expected to grow in the next future. In the last past years, computer-assisted procedures represent one of the trends that are transforming the way of practicing medicine. Cornering the Total Knee Arthroplasty, digital models of the joints have been used to carry out simulation of their kinematics and mechanical performance. Whilst for the 3D digital reconstruction of the patient geometry several studies have been conducted, an approximated geometry of the prosthesis has been several times employed, with undeniable consequences on the final results. This paper aims at comparing two non-contact reverse engineering technologies to acquire the shape of femoral components employed for total knee arthroplasty. A high-level device (Konika Minolta Vivid 9i) and a mid-low cost laser (NextEngine) has been compared. For the comparison, a systematic procedure of acquisition and elaboration of the results has been adopted in order to have as unbiased as possible results. The procedure involves the use of the proprietary software of the scanners for the elaboration of the raw data and the meshing procedure has been kept the same for all the models. Since the as-is acquired mesh is of high-resolution, a decimation procedure has been carried out in order to make the 3D models lighter and easier to be handled. Once the decimation procedure has been evaluated comparing the original and the simplified models to one another, the digitalized models have been compared with the measurements taken from a coordinate measuring machines. As a preliminary result, the two lasers seem to be adequate to accomplish the reverse engineering process as required by this application. Of course, the mid-low cost laser would be preferable whether the performance will be confirmed to be (statistically) equal.

The purpose of this study was to determine the concentrations of cobalt, chromium, and molybdenum in the serum of paediatric tumour patients after fixed hinge total knee arthroplasty. Further, these metal ion levels were compared with serum metal ion levels of patients with other orthopaedic devices such as hip and knee prostheses with metal-on-metal or metal-on-polyethylene articulation to find differences between anatomical locations, abrasion characteristics, and bearing surfaces. After an average follow-up of 108 months (range: 67 to 163) of 11 paediatric patients with fixed hinge total knee arthroplasty, the mean concentrations for Co and Cr were significantly increased while Mo was within the limits compared to the upper values from the reference laboratory. Furthermore, these serum concentrations were significantly higher compared to patients with a standard rotating hinge device (P=0.002andP<0.001) and preoperative controls(P<0.001). On the other hand, the serum levels of patients following MoM THA or rotating hinge arthroplasty using megaprostheses were higher. Therefore, periodic long-term follow-ups are recommended due to the rising concerns about systemic metal ion exposure in the literature. Upon the occurrence of adverse reactions to metal debris the revision of the fixed hinge implant should be considered.

Aim: To evaluate the prevalence of self-directed cannabidiol (CBD) use in patients with end-stage degenerative hip and knee arthritis who underwent total hip arthroplasty and total knee arthroplasty. Materials & methods: Anonymous surveys for 109 patients were completed at 6 weeks follow-up after either total hip arthroplasty or total knee arthroplasty at a single tertiary care US orthopedic hospital. Results: Within the perioperative window encompassing both preoperative and postoperative periods, 22% (95% CI: 14–30%) of patients used CBD. Conclusion: There was no difference in pain satisfaction between patients who used CBD and patients who did not. Given high rates of self-directed perioperative CBD use and the mixed body of evidence, further research is needed to better understand whether CBD is safe and effective.

Introduction: The primary goal of total knee arthroplasty (TKA) is to resolve knee destruction and associated problems at the end stages of diseases such as osteoarthritis and rheumatoid arthritis. High satisfactory rate has been reported in terms of pain relief and correction of deformity. However, the method for objective assessment of the outcome, such as range of motion (ROM) and quantitative evaluation of the clinical outcome of TKA, is to be confirmed. The purpose of this study was mandatory to investigate the ROM objectively and the newly designed prostheses. Materials and methods: The study was done in randomly selected patients who received dynamic measurement of knee function. Twenty-six patients participated in the study. They were divided into two groups (13 patients in A and 13 patients in B group), according to the knee prostheses they had received. Basic knee functions were evaluated in various dynamic activities, including nonweight bearing status of knee flexion, level walking, kneeling, and squatting, using computerized gait analysis techniques (Vicon 512 system). Passive knee ROM and static alignment were measured using traditional goniometer. HSS scores, physical, and neural examination were recorded. Results: After comparing patients in almost similar criteria, results have shown that there was no significant difference between two types of knee prostheses in randomly selective patients. Conclusion: Newly designed prostheses for achieving higher flexion angle cannot guarantee to provide better knee flexion for every patient. A patient, who can achieve higher knee flexion in pre-operative status, will have high flexion results in post-operative result. In other words, poor knee flexion function in pre-operation will lead to poor knee flexion function in post-operation status. Minor prosthesis design has little to do with the surgical outcome of knee flexion.

AbstractOrthopaedic surgeons commonly have the misconception that patients with tibial plateau fractures will likely go on to posttraumatic knee arthritis requiring total knee arthroplasty (TKA). In younger patients, osteochondral allograft (OCA) transplantation is an alternative method to address posttraumatic knee arthritis. The purpose of this study was (1) to identify our institutional failure rate following tibial plateau open reduction and internal fixation (ORIF) (failure was defined as conversion to TKA or OCA); (2) to determine if there are patient- or injury-related risk factors predictive of failure; and (3) to characterize differences between patients treated with TKA versus those treated with OCA transplantation. A 10-year retrospective review was conducted to identify patients treated at our institution with a tibial plateau fracture. Patients included in the final analysis were at least 18 years of age with an articular fracture (AO/OTA 41 B/C). The primary outcome was subsequent ipsilateral OCA or TKA. There were 350 patients (359 tibial plateau fractures) with a mean follow-up of 22.3 months (range, 6–133 months) who met inclusion criteria. Twenty-seven fractures (7.5%) were subsequently converted to a TKA or OCA at an average of 3.75 ± 3.1 years following their initial surgery. Patients who consumed tobacco were 2.3 times more likely to require a joint replacement (confidence interval [CI], 1.0–5.2; p = 0.04). Those patients who received an OCAs were significantly younger as compared with their TKA peers, both at time of initial injury (37 vs. 51 years, p = 0.02) and at time of surgery (41 vs. 55 years, p = 0.009). The joint replacement rate in this study is similar to those studies in the published literature that focused solely on the prevalence of conventional TKA. Tobacco is a risk factor for failure following tibial plateau ORIF. Patients who were treated with an OCA were younger at time of injury and failure.
