AbstractLateral compartment cartilage deterioration is the most common complication affecting medial unicompartmental knee arthroplasty (UKA) survivorship. The purpose of this study was to determine the best method of judging the degeneration of cartilage in the lateral compartment after medial UKA through analysis of different radiographic views. Forty-two participants were divided into two groups. Patients in Group A were followed for at least 10 months after undergoing a medial UKA (mean: 17.67 ± 7.65 months, range: 10–24 months), whereas those in Group B were evaluated 3 days after surgery. Joint space width in the lateral compartment of all patients was evaluated using three types of knee radiographs: weight-bearing anterior posterior (AP), supine AP, and supine valgus stress. No difference in joint space width in the lateral compartment after medial UKA was found for the three kinds of radiographs in Group A (F = 0.97, p = 0.39) and Group B (F = 1.499, p = 0.233). After evaluating the patients 3 days after surgery or following them for approximately 18 months after medial UKA, we determined that weight-bearing AP, supine AP, and supine valgus stress knee radiographs were comparable when used to assess residual cartilage thickness of the lateral compartment.

AbstractEffect of patellofemoral (PF) chondromalacia on results of high tibial osteotomy (HTO) has not been identified. Therefore, the objective of the present study was to analyze the effect of PF chondromalacia on relatively short-term radiographic and clinical outcomes of HTO. Patients who underwent open wedge HTO (OWHTO) from February 2010 to January 2015 were enrolled. A total of 101 knees were divided into two groups: 56 knees without PF chondromalacia in group A, while 45 knees with PF chondromalacia extended to subchondral bone in group B. Radiologic outcomes were compared using mechanical tibiofemoral angle, ratio of weight-bearing line (WBL), and minimal joint space width of the lateral compartment. Clinical outcomes were compared using range of motion in affected knee, visual analog scale, modified Lysholm score, and Kujala score. The mean mechanical tibiofemoral angle was 4.6 degree in group A and 4.8 degree in group B. The mean ratio of WBL was 63.8% in group A and 63.6% in group B at final. The mean minimum joint space width of the lateral compartment was 5.8 mm in group A and 5.8 mm in group B on standing AP radiograph. It was 5.3 mm in group A and 5.4 mm in group B on Rosenburg view at final. The mean ROM was 137.2 degree in group A and 137.5 degree in group B. The mean visual analog scale was 2.1 in group A and 2.3 in group B at final. The mean modified Lysholm score was 90.6 in group A and 89.1 in group B at final. The mean Kujala score was 90.2 in group A and 89.1 in group B at final. PF chondromalacia does not influence short-term radiographic and clinical outcomes following OWHTO.

Aim: Medial meniscus posterior root tear (MMPRT) causes meniscal extrusion, loss of meniscus function, arthritic changes. Clinical history, physical examination and magnetic resonance imaging (MRI) findings are useful for the diagnosis of MMPRT. The aim of this study is to evaluate the utility of stress X-rays in the diagnosis of MMPRT. Methods: Twenty patients who had undergone high tibial osteotomy between March 2015 and May 2016 and whose preoperative bilateral varus and valgus stress x-rays (Telos device) along with weight bearing x-rays were available were included. These patients were grouped into two according to integrity of posterior roots of their medial menisci; there were ten patients both in the study and control groups. Lateral joint space width (LJW) on varus stress x-rays, medial joint space width (MJW) on valgus stress x-rays as well as LJW and MJW on weight bearing x-rays were measured bilaterally. Intragroup comparisons of joint space widths between index and opposite knees were performed. Differences of MJW and LJW between index and opposite knees were calculated. Differences of joint space widths between stress x-rays and weight bearing x-rays were also calculated. The changes in joint space widths between the two groups were compared. Statistical analyses were performed utilizing SPSS 18.0. Significance level was set at 0.05. Results: In MMPRT group, opening of LJ space of index knees under varus stress was greater than that of opposite knees (Index: (mean±SD) 10,27±1,17 mm, opposite: 8,61±1,37 mm; p<0,0001). In the control group the difference was not significant (Index: 9,29±2,55 mm, opposite: 9,68±1,44 mm; p=0,566). The difference in the opening of LJW (under varus stress) between index and opposite knees was significantly greater in the study group (p=0,013). The difference between LJW under weight-bearing and varus stress conditions was significantly greater in the study group. (Study: 3,64±0.217 mm, control:2,28±0,182 mm, p=0.018). Conclusions: The findings of this study showed that in patients who had MMPRTs, an increased opening in the LJW was observed under varus stress conditions. This may be relevant with the fact that when varus stress is applied, meniscal extrusion is increased in case of a MMPRT. Stress x-rays could be a useful tool in the diagnosis of MMPRTs. Further studies are needed to determine the sensitivity and specificity of this diagnostic tool.

Purpose: the aim of the study was to compare the minimal joint-space (MJS) width of the tibiofemoral joint (TFJ) in weight-bearing radiograms with the patient in two different positions Material and Methods: from a study of 54 patients with chronic knee pain (aged 42–59 years, mean 52 years), we selected 21 consecutive patients for this study. in these 21 patients, both knees were examined by means of p.a. weight-bearing radiograms in semiflexion with fluoroscopic guidance. the patient stood with the weight: 1) almost entirely on the examined leg; and 2) equally distributed on both legs. the MJS was measured with a scale loupe in tenths of a millimeter in the medial and lateral compartments of the TFJ Results: with the patient standing on one leg, the MJS was 0.18 mm wider (p<0.006) in the medial compartment and 0.18 mm narrower (p<0.029) in the lateral compartment as compared to standing on both legs Conclusion: with the technique used, the assessment of the MJS width in the p.a. view of the TFJ in weight-bearing examinations should be performed with equal weight on both legs. Standing on only the examined leg might be an option in cases of suspected narrowing in the lateral compartment

Background: Osteoarthritis (OA) of the knee is one of the major causes in musculoskeletal condition leading to functional loss in patients. Determining the progression of the disease is a useful tool which will help in the planning of the exercise programme to slow or halt the disease progression. Measuring the joint space width of the tibiofemoral joint is one of the best options for knowing the disease progression and helps in designing an exercise programme. Aim: Retrospective measurement of joint space width in patients with bilateral tibiofemoral osteoarthritis of the knee joint. Methodology: Data was retrieved from the picture archiving and communication system (PACS) from 1st of February to 22nd of June 2018. Radiographs that were showing OA knee features by using Kellegren Lawrence (KL) grading system were considered and the joint space between the tibial and femoral compartment was measured. Result: The joint space width showed more reduction in the medial compartment of the joint as compared to the lateral compartment. Conclusion: In the rural population of Maharashtra the medial joint space is markedly decreased as compared to the lateral compartment of the tibiofemoral joint and as the KL grade increases the joint space width decreased. Keywords: Osteoarthritis; Knee; Joint space width; Rural Maharashtra.

Background: A high prevalence of osteoarthritis (OA) progression in patients with lateral meniscal defects has been reported. However, optimal management techniques for active patients remain ill-defined. Hypothesis: Meniscoplasty by capsular advancement with the application of the centralization technique would improve clinical and radiological outcomes in patients with lateral compartment OA attributed to lateral meniscal defects. Study Design: Case series; Level of evidence, 4. Methods: A total of 27 patients were enrolled who had undergone meniscoplasty by capsular advancement for lateral compartment OA attributed to lateral meniscal defects. In these patients, the meniscotibial capsule was released from the tibia and advanced with the remaining meniscus onto the rim of the tibial plateau to reform a meniscus-like configuration. Measures of clinical outcomes included clinical examination, Lysholm score, International Knee Documentation Committee (IKDC) subjective score, Knee injury and Osteoarthritis Outcome Score (KOOS), subjective rating scales regarding recovery of the operated knee, and sports performance level. Measures of radiographic outcomes included meniscal extrusion width or regeneration of the meniscus-like tissue on magnetic resonance imaging and lateral joint space width on standing extension anteroposterior and Rosenberg views. All clinical and radiographic outcomes were reported preoperatively and 2 years postoperatively, except magnetic resonance imaging findings, which were reported preoperatively and 1 year postoperatively. Results: The clinical outcomes were significantly improved 2 years postoperatively as compared with baseline: Lysholm score, IKDC subjective score, and KOOS subscores (all P < .0001). The patients’ subjective recovery ( P < .0001) and sports performance level ( P < .0001) were also improved. One year postoperatively, 10 of 11 patients who had no meniscus remaining at the middle segment showed more than one-third the volume of meniscal tissue–like regeneration, and meniscal extrusion width was significantly reduced as compared with baseline in the remaining 16 patients ( P = .0006). Joint space width increased at 2 years on the standing anteroposterior view ( P < .0001) and the Rosenberg view ( P = .0001). Conclusion: Meniscoplasty of the lateral meniscus by capsular advancement improved clinical and radiographic outcomes at 2-year follow-up in patients with lateral compartment OA attributed to lateral meniscal defects.
