Ligoniai ir metodai 1998–2002 metais KMU Ortopedijos ir traumatologijos klinikoje atliktos 87 autologinės mozaikinės transplantacijos operacijos esant kelio sąnario kremzlės ir kaulo pažeidimams. Pacientų amžiaus vidurkis operacijų metu buvo 24,74 ± 7,20 metų (14–40 metų). Simptomai vidutiniškai truko 21,32 ± 5,57 mėnesio, o pacientai įvertinti praėjus vidutiniškai 24,4 mėnesio (nuo 12 iki 60 mėnesių) po operacijos. Rezultatai apibendrinti naudojant ICRS (International Cartilage Repair Society) anketą, 13 (15%) atvejų – remiantis kartotinių artroskopijų metu atliktu makroskopiniu įvertinimu, 9 (11%) atvejais – histologiniu tyrimu, 57 (67%) atvejais – BMR ir visais atvejais – rentgeno tyrimais. Visus anketinius įvertinimus atliko nepriklausomas gydytojas ortopedas prieš operacijas ir po operacijų praėjus dvylikai, dvidešimt keturiems, trisdešimt šešiems, keturiasdešimt aštuoniems ir šešiasdešimčiai mėnesių. Nepriklausomi nuo tyrimo gydytojai, radiologas ir patologas, atliko visus BMR ir histomorfologinius įvertinimus. Rezultatai Praėjus vidutiniškai 24,4 mėnesio po mozaikinės transplantacijos, ICRS anketos būdu nustatytas klinikinis rezultatų pagerėjimas (p < 0,05). Funkcinis ir objektyvus įvertinimas pagal ICRS anketą buvo toks: 93% atvejų gauti geri ir labai geri operacinio gydymo rezultatai, kitais atvejais (7%) gydymo rezultatai buvo patenkinami. Kartotinių artroskopijų metu (remiantis ICRS protokolu), po operacijų praėjus vidutiniškai 12,4 mėnesio, 11 (84%) iš 13 atvejų buvo nustatytas geras ir labai geras sąnario kremzlės makroskopinis atsitaisymas. Sąnario kremzlės biopsijos ir histologinis tyrimas buvo atliktas 11% pacientų, ir daugumos jų (remiantis ICRS protokolu) sąnario kremzlės ir pokremzlinio kaulo atitaisymo koeficientas buvo geras. BMR tyrimas parodė, kad 94% pacientų sąnario paviršius atkurtas gerai arba labai gerai. Išvados Mūsų tyrimas parodė, kad po mozaikinės autologinės transplantacijos praėjus vidutiniškai 24,4 mėnesio (nuo 12 iki 60 mėn.) fiziškai aktyvių pacientų, kuriems buvo pažeista kelio sąnario kremzlė, klinikinė ir funkcinė būklė labai pagerėjo. Dauguma pacientų po kremzlės mozaikinės autologinės transplantacijos atgauna prieš pažeidimą buvusį fizinio aktyvumo lygį. Histomorfologinis persodintų transplantatų tyrimas parodė, kad visais tirtais atvejais išsilaikė hialininės kremzlės struktūra ir fibroelastinio audinio intarpai tarp transplantatų. Reikšminiai žodžiai: sąnario kremzlės pažeidimai, mozaikinė transplantacija Mosaic-like autologous osteochondral transplantation for the treatment of knee joint articular cartilage injuries Rimtautas Gudas1, Romas Jonas Kalesinskas1, Giedrius Bernotavičius1, Eglė Monastyreckienė2, Angelija Valančiūtė3, Darius Pranys4 Objective The purpose of this prospective clinical study was to evaluate the outcomes of mosaic type autologous osteochondral transplantation procedure for the treatment of the articular cartilage defects of the knee joint. Patients and methods Between 1998 and 2002, a total of 85 patients underwent an osteochondral autologous transplantation (mosaicplasty) procedure for osteochondral or chondral knee joint injury. The patients were evaluated using the ICRS score, arthroscopically, histologically, with MRI and X-ray examinations. The mean duration of symptoms was 21.32 ± 5.57 months and the mean follow-up was 24.4 months (range, 12 to 60 months). The mean age of the patients during the surgery was 24.74 ± 7.20 years (range, 14 to 40 years). An independent observer performed a follow-up examination after six, twelve, twenty-four, thirty-six and forty-eight months. In 13 (15%) of 85 cases 12.4 months postoperatively, arthroscopy with biopsy for histological evaluation was carried out. A radiologist and a pathologist, both blinded to each patient’s treatment, did the radiological and histological evaluations. Results After 24.4 months all the patients showed a significant clinical improvement (p < 0.05). The cartilage Repair Society (ICRS) score, functional and objective assessment revealed 93% to have excellent or good results after mosaicplasty; 7% were fair 24.4 months (range, 12–60 months) after the operations. The ICRS evaluation showed a significant improvement after the mosaicplasty procedure 24.4 months following operations (p = 0.005). No serious complications were reported. The ICRS for macroscopic evaluation during arthroscopy 12.4 months after mosaicplasty demonstrated excellent or good repair in 11 (84%) of 13 cases. Biopsy specimens were obtained from 9 (69%) of 13 patients, and histological evaluation of repair showed good scores (according to ICRS) for most samples after mosaicplasty. A MRI evaluation demonstrated excellent or good repairs in 94% after mosaicplasty. Conclusions On an average after 24.4 months (range, 12 to 60 months) of follow-up, our clinical study has shown a significant improvement of the clinical status of the physically active patients after the mosaic type autologous osteochondral transplantation for the repair of articular cartilage defects in the knee. Histologically, the osteochondral cylinder transplants retained hyaline cartilage. Keywords: articular cartilage injury, osteochondral mosaic-like transplantation

Background: Uncontained-type osteochondral lesions of the talus (OLTs) have been shown to have inferior clinical outcomes after treatment with bone marrow stimulation. While autologous osteochondral transplantation (AOT) is indicated for larger lesions, no study has reported on the prognostic significance of the containment of OLTs treated with the AOT procedure. Purpose: To clarify the effect of the containment of OLTs on clinical and radiological outcomes in patients who underwent AOT for OLTs. Study Design: Case control study; Level of evidence, 3. Methods: A retrospective cohort study comparing patients with contained-type and uncontained-type OLTs was undertaken to include all patients who underwent AOT for the treatment of OLTs between 2006 and 2014. Analyses were performed by grouping the patients according to the containment type. Clinical outcomes were evaluated using the Foot and Ankle Outcome Score (FAOS) and the 12-Item Short Form Health Survey (SF-12) preoperatively and at final follow-up. Magnetic resonance imaging (MRI) at 2 years’ follow-up was evaluated with the modified magnetic resonance observation of cartilage repair tissue (MOCART) score. Multivariate regression models were used to evaluate factors affecting postoperative FAOS, SF-12, and MOCART scores. Results: Ninety-four patients were included: 31 patients with a contained-type OLT and 63 patients with an uncontained-type OLT. The median patient age was 34 years (interquartile range [IQR], 28-48 years) in the contained-type group and 36 years (IQR, 27-46 years) in the uncontained-type group. The median follow-up time was 45 months (IQR, 38-63 months) in the contained-type group and 52 months (IQR, 40-66 months) in the uncontained-type group. The median FAOS and SF-12 scores improved significantly after surgery in both contained-type and uncontained-type lesions ( P < .001). The median postoperative FAOS score of patients with contained-type OLTs was higher than that of patients with uncontained-type OLTs (91.7 vs 85.0, respectively; P = .009), but no significant differences were found between the contained-type and uncontained-type groups for postoperative SF-12 and MOCART scores. The multivariate regression models showed that patients with contained-type OLTs had an approximately 10-point better score on the FAOS compared with patients with uncontained-type OLTs ( P = .006). There was a nonsignificant trend for the rate of cystic occurrence in uncontained-type OLTs to be higher than that of contained-type OLTs (55.6% vs 38.7%, respectively; P = .125). Conclusion: Patients with contained-type OLTs experienced better clinical outcomes than those with uncontained-type OLTs after AOT for the treatment of OLTs. However, the AOT procedure still provided good clinical and MRI outcomes in both contained-type and uncontained-type OLTs at midterm follow-up.

Category: Ankle Introduction/Purpose: Autologous osteochondral transplantation (AOT) is an established treatment for large-sized OLT, typically greater than 107mm2. Several studies have demonstrated favourable outcomes following AOT at short- and mid-term follow-up. However, the majority of the literature on AOT has short-term follow-up and little evidence exists on the mid-term and longer-term follow-up. Additionally, few studies include a large number of patients or have a high level of evidence, limiting the ability to draw broad and meaningful conclusions about the effectiveness of the AOT procedure for the treatment of OLT beyond short-term follow-up. The purpose of the current systematic review was to evaluate the clinical outcomes analysing level and quality of evidence of the AOT procedure in the treatment of OLT at mid-term and long-term follow-up. Methods: A systematic search of the MEDLINE, EMBASE and Cochrane Library databases was performed in October 2017 based on the PRISMA guidelines. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Clinical outcomes, and complications were also evaluated. Results: Eleven studies, with 500 ankles were included at a mean 62.8 months follow-up. There were 3 studies of LOE III, and 8 studies of LOE IV. There were 3 studies of fair quality and 8 studies of poor quality. The weighted mean preoperative AOFAS score was 55.1 ± 6.1, and the postoperative score was 86.2 ± 4.5, with 87.4% of patients being reported as excellent or good results. In total, 54 of the 500 patients (10.8%) had complications. The most common complication was donor site morbidity with 18 patients (3.6%) at final follow-up. Thirty-one patients (6.2%) underwent reoperations, and the authors deemed a total of 5 ankles (1.0%) failures. Only 5 studies (45.5%) used MRI for follow-up evaluation. Conclusion: The current systematic review demonstrated that good clinical and functional outcomes can be expected following AOT procedure for the treatment of OLT, with a failure rate of only 1.0% at 63 months follow-up. MRI and radiographs showed restoration of articular surface as well as a minimal presence of osteoarthritis at mid-term follow-up. However, there is still lack of data from high LOE and QOE studies, and further high quality studies are necessary.
