After 25 years of computer-navigated total knee arthroplasty, where do we stand today?

Background: Limb and implant alignment along with soft tissue balance plays a vital role in the outcomes after total knee arthroplasty (TKA). Computer navigation for TKA was first introduced in 1997 with the aim of implanting the prosthetic components with accuracy and precision. This review discusses the technique, current status, and scientific evidence pertaining to computer-navigated TKA.

COL4A1 mutation in an Indian child presenting as 'Cerebral Palsy' mimic.

The COL4A1 gene () plays an important role in vascular basement membrane function and pathogenic mutations have been reported in mice and humans. The gene is expressed mainly in the human brain, eyes and kidneys. Pathogenic mutations result in a vast array of manifestations that can present throughout life including the foetal period.

Survival and outcomes of different head sizes in primary total hip arthroplasty.

The femoral head size influences dislocation, range of motion (ROM), functional outcome, wear, and survival after total hip arthroplasty (THA). These aspects of different head sizes with contemporary bearings in primary THA have been reviewed. Based on the existing evidence, for highly-cross-linked polyethylene (HXLPE) bearings, a 32 mm cobalt chromium (CoCr) or ceramic head appears to be a suitable choice.

Technical and surgical causes of outliers after computer navigated total knee arthroplasty.

Background: Navigated total knee arthroplasty (TKA) improves implant and limb alignment but outliers continue to exist. This study aimed to determine the technical and surgical causes of outliers.

Methods: This retrospective cohort study included 208 patients who had undergone navigated TKA.

Ankle and Hindfoot Symptoms after Medial Open Wedge High Tibial Osteotomy.

Medial open wedge high tibial osteotomy (MOWHTO) is a commonly performed procedure for symptomatic medial compartment osteoarthritis (OA). However, little is known about its effects on ipsilateral ankle or hindfoot. The aim of our study was to determine the incidence of ankle or hindfoot problems after MOWHTO and examine its association with radiological indices.

Changes in spinopelvic indices after hip arthroplasty and its influence on acetabular component orientation.

Objective: To evaluate spinopelvic changes after hip arthroplasty in standing and ready-to-rise positions.

Methods: We compared pelvic tilt, sacral slope, cobb's angle, and hip flexion on pre and postoperative spinopelvic radiographs.

Results: Standing: All postoperative indices were similar to preoperative ones except sacral slope (mean difference:1.

Late Dislocations After Total Hip Arthroplasty: Is the Bearing a Factor?

Background: Dislocation is a leading cause of revision after primary total hip arthroplasty (THA). Although more common in the first few years after the procedure, dislocation can occur at any time. This study investigated the difference in late dislocation in ceramic-on-ceramic (CoC) bearings compared with metal-on-polyethylene and ceramic-on-polyethylene bearings in THA.

Computer Navigation Helps Reduce the Incidence of Noise After Ceramic-on-Ceramic Total Hip Arthroplasty.

Background: Noise after ceramic-on-ceramic (CoC) total hip arthroplasty (THA) is a well-recognized problem. Computer navigation has been shown to achieve desired implant orientation. Our aim was (1) to compare the incidence of noise between navigated and conventional CoC THAs and (2) to determine the factors associated with noise.

Annulo-nucleoplasty using Disc-FX in the management of lumbar disc pathology: early results.

Background: Back pain due to Lumbar Disc Disease is a major clinical problem. The treatment options range from physiotherapy to fusion surgery. A number of minimally invasive procedures have also been developed in the recent past for its management.

Cemented cruciate-retaining total knee arthroplasty in osteoarthritis: a comparison of pegged and stemmed tibial designs.

We compared the clinical, functional, and radiographic outcomes between pegged (37 knees in 37 patients) and stemmed (33 knees in 31 patients) tibial designs in patients undergoing primary cemented total knee arthroplasty (TKA) for osteoarthritis (OA). Outcomes were evaluated using the knee society score (KSS-Clinical and Function scores) and knee injury and osteoarthritis outcome score (KOOS-pain, symptoms, stiffness, and function scores) at 6, 12, and 24 months postoperatively. Pre- and postoperative radiographs were evaluated for alignment and tibial coverage.

Discogenic axial back pain: is there a role for nucleoplasty?

Study Design: A prospective observational study.

Purpose: To evaluate the role of nucleoplasty in the management of discogenic axial back pain; to determine the influence of concordant pain during provocative discography, annular tear and loss of disc height on the outcome of nucleoplasty.

Overview Of Literature: The role of nucleoplasty in the management of radicular leg pain due to disc herniation is known.

CT based evaluation of odontoid morphology in the Indian population.

Background: Anterior fixation using two 3.5 mm screws is typically recommended for type II odontoid fractures. However, it is unsuitable in patients with an odontoid diameter of <9.

Bicompartmental versus total knee arthroplasty for medio-patellofemoral osteoarthritis: a comparison of early clinical and functional outcomes.

Severe medio-patellofemoral osteoarthritis (MPFOA) is often managed with a total knee arthroplasty (TKA). Bicompartmental knee arthroplasty (BKA), as compared with TKA can offer a bone and ligament preserving solution for MPFOA. We aimed to compare the early clinical and functional outcomes of modular BKA (n = 16) with TKA (n = 20) in MPFOA.

Atlantoaxial arthrodesis using C1-C2 transarticular screw fixation in a case of Morquio syndrome.

Prophylactic or therapeutic arthrodesis is recommended for atlantoaxial instability in Morquio syndrome. Occipitocervical fusion, the common approach for upper cervical fusion in Morquio syndrome sacrifices the movements at the occipitoatlantal joints. The use of C1-C2 transarticular screws for achieving C1-C2 arthrodesis, without compromising mobility at the occipitoatlantal joint in Morquio syndrome has not been reported.
