Objective To identify whether the medial or lateral approach is superior for patients with valgus knees undergoing primary total knee arthroplasty (TKA). Methods Studies evaluating the 2 approaches were sourced from the PUBMED, EMBASE, Web of Science, and OVID databases. The quality of included studies was assessed using a modified quality evaluation method, and differences between approaches were systematically reviewed. Results Seventeen observational studies were included. The studies were published between 1991 and 2016, and included 5 retrospective studies and 12 prospective studies. Sixteen evaluation methods for the study outcomes were identified. Twelve and eight complication types were identified by studies reporting the lateral and medial approaches for valgus knee, respectively. Several studies showed that pain scores and knee function were superior using a lateral approach. Conclusion The lateral approach (combined with a tibial tubercle osteotomy or proximal quadriceps snip) was more useful and safer than the medial approach in the treatment of severe uncorrectable valgus knee deformity in patients undergoing TKA. Most of the available evidence supports the use of a lateral approach provided that the surgeon is familiar with the pathological anatomy of the valgus knee.

Introduction: To invest the auxiliary role of Patient specific Instrument(PSI) used as osteotomy guide plate in total knee arthroplasty(TKA) with valgus knee. Hypotheses: PSI osteotomy guide plate is applicable for total knee arthroplasty with valgus knee. Methods: A retrospective analysis was performed on 21 patients with valgus knee, including 5 males and 16 females, who underwent TKA in joint surgery department I of ZhengZhou Orthopaedic Hospital from March 2016 to February 2018. All the operations were performed with the assistance of PSI, and the radiographic and clinical evaluations including femoral tibial joint ectropion angle(FTA) before and after operation, range of motion(ROM) and the Hospital for Special Surgery (HSS) knee score were reviewed, and surgical complications were recorded. Results: All the 21 patients werefollowed up for 10 ˜ 26 months (mean 16 months).All the incisions healed by first intention. The FTA was reduced significantly to 6.3 °±1.2° after operation from 17.6 ° + 5.7 °(P < 0.05), the ROM was improved significantly from preoperative 71.3° ±5.8° to postoperative 102.4°±7.5° (P < 0.05), the HSS score at the last follow-up was improved from 38.2±5.7 to 87.5-3.5(P < 0.05). During the follow-up, no complications such as infection, loosening, sinking and valgus were observed. Conclusion: Providing accurate osteotomy, effective correction of the force line, simple operation and satisfactory clinical effect, the PSI osteotomy guide plate is applicable for total knee arthroplasty with valgus knee.

Background: The constrained knee prosthesis has the basic indication in revision arthroplasty, but the latest literature reveals that it takes place also in primary total knee arthroplasty in cases of knee osteoarthritis associated with major deformities. Material and methods: Present study is based on the surgical treatment, using the constrained knee prosthesis in the primary total knee arthroplasty, during 2019-2021, of 28 patients with knee osteoarthritis associated with severe deformities in varus or valgus, in the Big Joint Replacement Department, Clinical Hospital of Traumatology and Orthopedics, Chisinau. Results: In this study, the following criteria were evaluated: the type of deformity – valgus (10 cases) and varus (18 cases); the degree of deformation – for varus knees was on average 300 , and for valgus knee – 250 ; bone attrition – 11 cases with bone defects where it was necessary to use augmentations; affected side – in 19 cases the right knee was affected and 9 cases the left one; the women/men ratio was 4/1; the mean age of the patients was 67.5 years; average duration of the intervention – 140 minutes; in 5 cases a lateral para-patellar approach was performed, of which 2 cases with tibial tuberosity osteotomy; complications – 1 case with intra-operative periprosthetic fracture and 2 cases with superficial infections of the operated joints. Conclusions: Osteoarthritis of the knee progresses rapidly, leading to severe deformities, significant bone defects and joint instability, which are indications to use the constrained prosthesis in the primary total knee arthroplasty, long-term follow-up is necessary to obtain the last conclusion, but from this study the constrained knee prosthesis like primary implant for special indication had promising results.

Malalignment of the components affects long term total knee arthroplasty (TKA) survival. One of the options for achieving better TKA alignment may be a detailed preoperative radiological assessment. The aim of the study – to investigate the femoral valgus angle variations and affecting factors in patients with knee osteoarthritis (OA). Material and methods: We prospectively investigated severe OA patients, admitted for elective TKA. The standardized radiological assessment was performed – long standing hip-knee- ankle radiographs and the measurements were taken. We evaluated the relationship between the patients’, radiological parameters and femoral valgus angle. Results: 110 patients were included in the study and the mean measured femoral valgus angle was 6,7±1,3° and ranged from 4° to 10°. It was not significantly different between genders or varus/ valgus knee deformation. There was a significant relation between femoral valgus angle and neck-shaft, femoral bowing angles. Femoral valgus angle significantly increased with larger femoral bowing and smaller neck-shaft angles. Conclusions: Lithuanian patients with knee OA scheduled for TKA had a mean femoral valgus angle of 6,7±1,3° which ranged from 4° to 10°. Femoral neck-shaft and bowing angles significantly affects the femoral valgus angle.
