“…Although the overall lifespan of the TKA prosthesis is affected by numerous patients and prosthetic technology-related factors, in all, the average service life is 15-20 years. Clinicians are encouraged to ensure that after all nonsurgical treatments are exhausted, excellent treatment results can be expected in population [77].…”

Knee osteoarthritis is a chronic degenerative disease companied with chronic knee pain and dysfunction. However, the etiology and pathogenesis of knee osteoarthritis were unclear. Currently, age, diet, trauma, obesity, and inheritance are the main risk factors. The major pathological hallmarks of knee osteoarthritis included subchondral bone sclerosis, articular cartilage degeneration, arthrosynovitis, and osteophyte. With the acceleration of the aging process in China, the treatment of knee arthritis and the methods to improve the quality of life have become the focus of medical staff. Currently, therapies in clinical practice include surgery and nonoperative treatment; however, the clinical effects of different individuals at different stages will still be very different. This article reviews the recent advances in the treatment of knee osteoarthritis from three aspects: nonsurgical treatment, surgical treatment, and modern new medical means.

“…The first modality is appropriate for delaying the patient’s years of joint replacement, but is appropriate for younger patients with less severe OA. The second modality requires asymmetric intra-articular osteotomy and ligament balancing to correct lower extremity force lines, but is limited by the site and severity of deformity, which is often ineffective for severe extra-articular deformities[ 6 ]. The third modality prolongs patient hospitalization and recovery time, increases the number of procedures, and also increases the odds of incisional infection and economic burden.…”

BACKGROUND Surgical treatment of knee osteoarthritis (KOA) complicated by extra-articular deformity has always been controversial regardless of whether it is simultaneous or staged. Simultaneous total knee arthroplasty (TKA) combined with supracondylar osteotomy without plate for treatment of KOA complicated by femoral varus deformity has not been reported in the literature. CASE SUMMARY A 53-year-old Chinese woman complained of left knee pain for 6 years that worsened for 4 mo during her visit on April 3, 2020, accompanied by instability in walking, which seriously affected quality of life. According to her medical history and preoperative imaging, the patient was diagnosed with left KOA with varus deformity. We used the angular center of rotation principle for osteotomy of the femur deformity and placed a poststabilized femur prosthesis into the knee joint. At the same time, a 13 mm × 130 mm femur extension rod was used instead of a steel plate to fix the end of the femur osteotomy, reducing the possible complications caused by steel plate implantation and reducing the economic burden on patients. The operation successfully solved two major problems of KOA and varus deformity, and the clinical and imaging evaluation of postoperative follow-up were satisfactory. CONCLUSION TKA and supracondylar femoral osteotomy can be used for simultaneous KOA treatment and deformity correction.

Background : Presence of an extra-articular deformity in the femur or tibia poses a challenge to the surgeon undertaking knee replacement procedure. The conundrum is whether to correct the deformity beforehand, or accept the deformity and compensate for this through placement of the implant. Material and Methods : This is a retro-spective study comprising six patients who had a knee replacement in the presence of an extra-articular deformity of the tibia treated at our centre. All six had the knee replacement without correction of deformity. The data evaluated included clinical outcome, mechanical axis correction, type of implant, and the use of any software / computer guidance. The deformity was managed through planning of tibial resection without the need for pre-operative deformity correction. Results : Mean age was 66.5 years. Mean coronal plane deformity in the tibia was 8.6 degrees. The hip- knee-ankle improved from a mean 12.6 degrees to 4 degrees. Mean Oxford knee score improved from a mean of 19 to 33.6. Conclusion : Planning the tibial resection on the basis of mechanical axis of tibia allows correction of alignment without the need for preoperative correction. Correction of the deformity may not be needed if the maximum tibial resection is less than 15 mm.

Outcomes after knee arthroplasty in extra-articular deformity

Abstract: In patients with extra-articular deformities, TKA with asymmetric intra-articular resection and ligament balancing can relieve pain and realign the mechanical axis of the lower limb.
