The main objective of the research project is to evaluate the results of the treatment of chondromalacia of the cartilage in the knee joint with the use of: autogenous transplantation of fragmented adipose tissue taken from the abdominal wall - (MyStem, Lipogems, Arthrex). PRP GF (platelet-rich plasma with growth factors) (Ycellbio, ACP Arthrex, Neoregen, FrankPharma), Mesenchymal cells centrifuged from bone marrow cells taken from the iliac crest - (Harvest, Arthrex), Hyaluronic acid - low molecular weight (Synvisc, Biolevox, ArtiAidPlus), Hyaluronic acid - cross-linked Arti Aid Plus, Synovial, Durolain, StavOn, Collagen - Guna, Orthokine. The specific objectives are: to compare the results of treatment of analogous zones of cartilage defects in the knee joint obtained in the study groups using two methods: microfractures and microfractures with simultaneous intra-articular injection of autogenous cartilage graft and PRP GF (Auto Cart-Arthrex method). The results for the operated limb in both groups will be compared both between the groups and with the results of clinical and biomechanical tests for the non-operated limbs.
The study will be prospective, randomized. The study groups will consist of 30 people with damage to analogous cartilage zones of the knee joint qualified for arthroscopic treatment. After surgery, patients will be improved according to the same rehabilitation protocol. The follow-up examination will include: subjective assessment and clinical examination on day 1, then after 3 and 6 months, MRI imaging, ultrasound after 6 months, biomechanical examination after 3 and 6 months. A detailed interview will be conducted in the study groups, supplemented with pain assessment on the 1st day after the procedure using the Visual Analogue Scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), then with the TAS activity level scale (TAS). Tegner Activity Level Scale), three parts of the 2000 International Knee Documentation Committee (2000 IKDC) questionnaire: Demographic Form, Current Health Assessment Form, percentage of drugs used acute treatment initiation, withdrawal rates due to knee pain, knee range of motion, and adverse events. The MRI examination will be carried out on a 1.5 Tesla apparatus, the ultrasound examination on a apparatus with the option of elastometry and BMI. Measurements of the range of motion of the knee joint, measurements of the circumference of the knee joint and thigh, measurements of the torques of the extensor and flexor muscles of the knee joint as well as the muscles responsible for the internal and external rotation of the lower leg relative to the thigh in the knee joint in static and isokinetic conditions, measurements of proprioception on the Biodex 4 measuring stand System, measurements of gait kinetics and kinematics using the BTS Smart optoelectronic system for three-dimensional movement analysis and two Kistler strain gauge platforms, as well as the squat test.

Tegner Activity Level Scale (TAS)
The Tegner Activity Scale (TAS) aims to provide a standardized method in determining the level of activity prior to injury and level of activity post injury that can be documented on a numerical scale. The Tegner activity scale is a one-item score that graded activity based on work and sports activities on a scale of 0 to 10. Zero represents disability because of knee problems and 10 represents national or international level soccer.
Time frame: 1 day

Visual Analogue Score (VAS)
In this method, the examined person marks a point on a line with a length of (for example) 10 cm, where the value 0 is assigned to the complete absence of pain, and the value 10 to the strongest pain imaginable.

Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is defined as a disease-specific instrument used for assessing quality of life, particularly focusing on activity limitation in individuals with osteoarthritis. The WOMAC consists of three subscales and has a total possible score range of 0 to 96: pain (five questions), stiffness (two questions), and physical function (17 questions). The subscale scores can vary, with pain ranging from 0 to 20 points; stiffness, 0 to 8 points; and physical function, 0 to 68 points. Lower scores indicate better health status (less pain, stiffness, and functional limitations), while higher scores represent worse outcomes ( worse pain, stiffness, and functional limitations).

Magnetic resonance imaging (MRI) of the knee joint
MRI (1.5 Tesli) will be used to assess the cartilage healing process following arthroscopic surgery. Radiological assessment will include cartilage defect fill, tissue integration, surface smoothness, and signal intensity of repair tissue. An imaging appearance indicative of effective healing is interpreted as a better outcome.
Time frame: 6 months after procedure
Ultrasound examination (USG) of the knee joint
Ultrasound examination on the apparatus with the option of elastometry will be used to assess postoperative tissue regeneration and intra-articular conditions. USG will be performed using a linear transducer with a frequency of 7-10 MHz. The evaluation will include: cartilage surface regularity and thickness, presence or absence of joint effusion, synovial membrane hypertrophy (synovitis), swelling or inflammatory changes in Hoffa's fat pad, signs of active inflammation. An imaging appearance indicative of effective healing is interpreted as a better outcome.
