1.
The Relationship Between the Optical Properties of Articular Cartilage and the Biomechanical Parameters of the Tissue
Kafian-Attari I, Ebrahimi M, Nippolainen E, Mirhashemi A, Paakkari P, Bergmann F, et al.
J Biophotonics . 2025 Feb; :e202400460. PMID: 39891344
This study investigates the relationship between the optical properties of articular cartilage with its biomechanical parameters. The absorption and reduced scattering coefficients of articular cartilage, and average maximum penetration depth,...
2.
The human patellar tendon is mechanically homogenous at its mid-substance
Kositsky A, Stenroth L, Nippolainen E, Torniainen J, Makela J, Paakkari P, et al.
J Mech Behav Biomed Mater . 2025 Jan; 163:106875. PMID: 39818097
The human patellar tendon contains distinct fascicle bundles across its mediolateral and anteroposterior regions. Studies have suggested region-specific behaviour during in vivo actions, but it is unclear whether such regional...

Machine Learning Approaches for the Fusion of Near-Infrared, Mid-Infrared, and Raman Data to Identify Cartilage Degradation in Human Osteochondral Plugs
Tafintseva V, Nippolainen E, Virtanen V, Solheim J, Zimmermann B, Saarakkala S, et al.
Appl Spectrosc . 2024 Nov; 79(3):385-395. PMID: 39512222
Vibrational spectroscopy methods such as mid-infrared (MIR), near-infrared (NIR), and Raman spectroscopies have been shown to have great potential for in vivo biomedical applications, such as arthroscopic evaluation of joint...

Comparison of site-specific tensile, compressive, and friction properties of human tibiofemoral joint cartilage and their relationship to degeneration
Ristaniemi A, Tuppurainen J, Jantti J, Nippolainen E, Afara I, Mononen M, et al.
J Biomech . 2024 Nov; 177:112386. PMID: 39492148
Site-specific differences in the compressive properties of tibiofemoral joint articular cartilage are well-documented, while exploration of tensile and frictional properties in humans remains limited. Thus, this study aimed to characterize...

Relationship between depth-wise refractive index and biomechanical properties of human articular cartilage
Khan B, Nippolainen E, Shahini F, Nonappa , Popov A, Toyras J, et al.
J Biomed Opt . 2024 Sep; 29(9):095003. PMID: 39309245
Significance: Optical properties of biological tissues, such as refractive index (RI), are fundamental properties, intrinsically linked to the tissue's composition and structure. We hypothesize that, as the RI and the...

Infrared Spectroscopy Can Differentiate Between Cartilage Injury Models: Implication for Assessment of Cartilage Integrity
Shahini F, Oskouei S, Nippolainen E, Mohammadi A, Sarin J, Moller N, et al.
Ann Biomed Eng . 2024 Jun; 52(9):2521-2533. PMID: 38902468
In order to improve the ability of clinical diagnosis to differentiate articular cartilage (AC) injury of different origins, this study explores the sensitivity of mid-infrared (MIR) spectroscopy for detecting structural,...

Estimation of Photon Path Length and Penetration Depth in Articular Cartilage Zonal Architecture Over the Therapeutic Window
Kafian-Attari I, Nippolainen E, Bergmann F, George A, Paakkari P, Mirhashemi A, et al.
IEEE Trans Biomed Eng . 2024 May; 71(8):2300-2310. PMID: 38748530
Objective: The key characteristics of light propagation are the average penetration depth, average maximum penetration depth, average maximum lateral spread, and average path length of photons. These parameters depend on...

Site-specific elastic and viscoelastic biomechanical properties of healthy and osteoarthritic human knee joint articular cartilage
Linus A, Tanska P, Nippolainen E, Tiitu V, Toyras J, Korhonen R, et al.
J Biomech . 2024 May; 169:112135. PMID: 38744145
Articular cartilage exhibits site-specific biomechanical properties. However, no study has comprehensively characterized site-specific cartilage properties from the same knee joints at different stages of osteoarthritis (OA). Cylindrical osteochondral explants (n ...

Non-neotissue constituents as underestimated confounders in the assessment of tissue engineered constructs by near-infrared spectroscopy
Elkadi O, Abinzano F, Nippolainen E, Gonzalez O, Levato R, Malda J, et al.
Mater Today Bio . 2023 Dec; 24:100879. PMID: 38130429
Non-destructive assessments are required for the quality control of tissue-engineered constructs and the optimization of the tissue culture process. Near-infrared (NIR) spectroscopy coupled with machine learning (ML) provides a promising...

Broadband scattering properties of articular cartilage zones and their relationship with the heterogenous structure of articular cartilage extracellular matrix
Kafian-Attari I, Nippolainen E, Bergmann F, George A, Paakkari P, Mirhashemi A, et al.
J Biomed Opt . 2023 Dec; 28(12):125003. PMID: 38094709
Significance: Articular cartilage exhibits a zonal architecture, comprising three distinct zones: superficial, middle, and deep. Collagen fibers, being the main solid constituent of articular cartilage, exhibit unique angular and size...
