Abstract:Single compartment osteoarthritis is a commonly encountered condition in the middle-aged population, with the medial compartment being the most commonly involved compartment. Medial compartment osteoarthritis becomes seriously disabling for these active patients, with a very few definitive solutions. These patients quickly stop responding to the conservative methods such as lifestyle modification, drugs, physiotherapy, and rehab programs. Less invasive procedures such as intra-articular injections or joint deb… Show more
“…34 Although no clinical association can be drawn between our findings and future degenerative changes, it is interesting to acknowledge the articular cartilage on the posterior aspect of the medial condyle was found to be the most affected area in advanced osteoarthritic knees. 35 Our findings are also consistent with a previous study by Goyal et al, 36 who showed that on the tibial surface, the medial, or posteromedial half of the medial tibial plateau, are the most common areas to suffer chondral damage.…”
Objective: While articular cartilage defects are common incidental findings among adult athletes, the effect of running on the cartilage of adolescent athletes have rarely been assessed. This study aims to assess the variations in the articular cartilage of the knees in healthy adolescent basketball players using quantitative T2 MRI (magnetic resonance imaging). Design: Fifteen adolescent basketball players were recruited (13.8 ± 0.5 years old). Girls were excluded to avoid potential gender-related confounding effects. Players underwent a pre-run MRI scan of both knees. All participants performed a 30-minute run on a treadmill. Within 15 minutes after completion of their run, players underwent a second, post-run MRI scan. Quantitative T2 maps were generated using the echo modulation curve (EMC) algorithm. Pre-run scans and post-run scans were compared using paired t test. Results: Participants finished their 30-minute run with a mean running distance of 5.77 ± 0.42 km. Pre-run scans analysis found statistically significant ( P < 0.05) changes in 3 regions of the knee lateral compartment representing the cartilaginous tissue. No differences were found in the knee medial compartment. Post-run analysis showed lower T2 values in the medial compartment compared to the pre-run scans in several weight-bearing regions: femoral condyle central (pre/post mean values of 33.9/32.2 ms, P = 0.020); femoral condyle posterior (38.1/36.8 ms, P = 0.038); and tibial plateau posterior (34.1/31.0 ms, P < 0.001). The lateral regions did not show any significant changes. Conclusions: Running leads to microstructural changes in the articular cartilage in several weight-bearing areas of the medial compartment, both in the femoral and the tibial cartilage.

“…The barrel vault osteotomy was subsequently published in 1976 by Maquet 5 (Fig 1A). More recently, opening wedge 6 and combination (opening/closing) valgus 7 tibial osteotomies have been described.Fig 1(A) Diagram of the Maquet barrel vault osteotomy with pins, left knee, premanipulation. (B) Diagram of the Maquet barrel vault osteotomy with parallel pins, left knee, postmanipulation.…”
The barrel vault tibial osteotomy performed for knee varus osteoarthritis avoids the complications of the opening wedge osteotomy and minimizes the potential complications of the lateral closing wedge osteotomy. It allows correction of large varus deformities in knee medial compartment osteoarthritis.
