“…(1) The PCL is nourished by the middle geniculate artery and innervated by branches of the tibial nerve. (2) The PCL functions to restrict posterior translation of the tibia in relation to the femur. It also contributes to the restraint of internal rotation (with the knee in flexion of 90° or more).…”

A 21-year-old man presented with left knee pain and instability from an injury sustained in a road traffic accident three months prior. He had been riding a motorcycle when he self-skidded, landing on the left side of his body. Besides the left knee injury, he had also sustained fractures of the left little and middle fingers (not elaborated here). Physical examination of the left knee revealed a positive posterior drawer test. Anterior drawer and pivot tests were negative. Magnetic resonance (MR) imaging of the left knee was performed. What do the serial medial-tolateral sagittal images of the knee (Fig. 1) show? What is the diagnosis? CMEArticle

“…Cruciate ligament tears are frequent in humans (incidence of 68.6 per 100.000 person‐years for the cranial cruciate ligament (Sanders et al, ); incidence unknown for caudal cruciate ligament). Caudal cruciate ligament tears are less common than cranial cruciate ligament tears and occur mainly in a multi‐ligament‐injured knee (Vaquero‐Picado & Rodriguez‐Merchan, ); it can be torn at its tibial or femoral attachments or more commonly through its substance. Isolated caudal cruciate ligament tears are uncommon and are often associated with meniscal tears and future symptomatic OA (Sanders et al, ).…”

Though the ovine stifle is commonly used as a model in research, there is no description of its anatomy at ultrasonography (US). The objective of this study was to provide reference US images of the ovine stifle that are relevant in musculoskeletal research. Four pairs of hindlimbs were scanned, whilst four other pairs were frozen and cut in different planes to compare gross anatomy to US scans. In another pair, the synovial compartments of the stifle were injected and scanned. This study demonstrated that US could be used to assess the ovine stifle. Several structures of clinical interest could be identified with cranial, lateral and medial approaches, such as (a) the tendons of m. quadriceps femoris, m. gluteobiceps, m. popliteus, (b) the common tendon of m. peroneus tertius–extensor longus digitorum–extensor digiti III proprius, (c) the patellar ligament, (d) the medial and lateral collateral ligaments, (e) the cranial horn and middle segment of medial and lateral meniscus, and (f) the synovial recesses. However, the caudal approach was not successful to identify caudal anatomical structures of the joint, due to the muscular mass, that is the caudal aspects of the articular surfaces of the femoral and tibial condyles, the caudal horns of the menisci and the supracondylar synovial recesses. In addition, US remained challenging to assess the internal structures such as cruciate ligaments and articular surfaces. The feasibility of US needs to be tested in vivo.

“…Diffusion is also one of the governing equations used to track the propagation of light through the biological tissues when scattering effect of the tissues assumed higher than absorption effect particularly 600 nm to 1000 nm range of the light spectrum.

“…6 Ligament, cartilage injuries and OA are the most common chronic knee pain and cause of disabilities. [2][3][4][5] In USA, there are about 60 acute meniscal tears per 100000 people 7 and around 200000 ALC injuries per year. 8 According to national health survey around 3 persons have OA per 10 people with disabilities.…”

Photo-diagnosis of knee diseases can provide noninvasive, contrasted, deep penetrating and higher resolution optical and temperature images. In this study, knee joint was modeled and simulated using finite element method, optical images and temperature images were generated for injured, osteoarthritis (OA) and normal knee conditions. Monte Carlo and diffusion approximation equation were used for absorption mapping and bioheat transfer equation to generate temperature information. Furthermore, the results found by Monte Carlo and diffusion approximation equation for the same parameters were compared. The results obtained in both Monte Carlo and diffusion approximation revealed that temperature mapping is capable for differentiating injuries of knee, OA and normal knee joints compared with optical absorption images. In the study, the average net temperature rise scored was 0.12 Kelvin for normal and 0.13 Kelvin for OA joints at 3μs, which is significant and become more significant at its logarithmic value to produce temperature images and small to produce thermal damage on the tissue. To conclude, photo diagnosis knee joint model mimics for detecting injuries and analyzing diseases of knee and other similar boney-ligament/cartilage complex body structures in diagnostic imaging and monitoring procedures by using the combination of thermal and optical absorption properties of joints. This work has valuable impact for optical diagnostic imaging.Citation: Muluneh MB, ElGohary SH. Thermal effect for optical imaging of knee osteoarthritis.Citation: Muluneh MB, ElGohary SH.
