Abstract. Objective. A common orthopaedic pain found in a wide spectrum of individuals, from young and active to the elderly is anterior knee pain (AKP). It is a multifactorial disorder which is thought to occur through muscular imbalance, overuse, trauma, and structural malalignment. Over time, this can result in cartilage damage and subsequent
Arthroscopic management of femoroacetabular impingement (FAI) has become the mainstay of treatment. However,
Femoroacetabular impingement is a prearthritic deformity frequently associated with early chondral damage. Several techniques exist for restoring larger cartilage defects. While AMIC proved to be an effective treatment in knee and ankle, there are only short-term data available in hip. This study aimed to investigate the mid-term clinical outcome of patients with
Introduction and Objective. Platelet-Rich-plasma (PRP) has been used in combination with stem cells, from different sources, with encouraging results both in vitro and in vivo in osteochondral defects management. Adipose-derived Stem Cells (ADSCs) represents an ideal resource for their ease of isolation, abundance, proliferation and differentiation properties into different cell lineages. Furthermore, Stem Cells in the adipose tissue are more numerous than from other sources. Aim of this study was to evaluate the potential of ADSCs in enhancing the effect of arthroscopic mesenchymal stimulation combined with infiltration of PRP. Materials and Methods. The study includes 82 patients. 41 patients were treated with knee arthroscopy, Steadman microfractures technique and intraoperative PRP infiltration, Group A. In the Group B, 41 patients were treated knee arthroscopy, Steadman microfractures and intraoperative infiltration of PRP and ADSCs (Group B). Group A was used as a control group. Inclusion criteria were: Age between 40 and 65 years, Outerbridge grade III-IV

Abstract. Objective. Articular cartilage damaged through trauma or disease has a limited ability to repair. Untreated, these focal lesions progress to generalized changes including osteoarthritis. Musculoskeletal disorders including osteoarthritis are the most significant contributor to disability globally. There is increasing interest in the use of mesenchymal stem cells (MSCs) for the treatment of focal
Chondral damage within the knee commonly occurs during sport following direct trauma or following degeneration through overuse. Radio frequency energy chondroplasty (RFC) can be used as an alternative to mechanical chondroplasty in the arthroscopic treatment of
Abstract. Introduction. Active, middle-aged patients with symptomatic cartilage or osteochondral defects can find themselves in a treatment gap when they have failed conservative measures but are not yet eligible for conventional arthroplasty. Data from various cohort studies suggests that focal knee resurfacing implants such as HemiCAP, UniCAP, Episealer or BioBoly are cost-effective solutions to alleviate pain, improve function and delay or eliminate the need for conventional replacement. A systematic review and meta-analysis were conducted in order to(i) evaluate revision rates and implant survival of focal resurfacing; (ii) explore surgical complications; and (iii) evaluate various patient reported clinical outcome measures. Methodology. PubMED, Cochrane Library and Medline databases were searched in February 2022 for prospective and retrospective cohort studies evaluating any of the available implant types. Data on incidence of revision, complications and various patient reported outcome measures was sourced. Results. A total of 24 unique studies were identified with a total of 1465 enrolled patients. A revision rate of 12.97% over a 5.9 year weighted mean follow-up period was observed across all implant types. However, in one series a Kaplan-Meir survival as high as 92.6% at a 10-year follow-up period was noted. A statistically significant improvement was documented across multiple subjective clinical outcomes scores. There was a low reported incidence of post-operative complications such as aseptic loosening or deep wound infection. Conclusions. Focal femoral resurfacing appears to be a viable treatment option for focal symptomatic

Aims. Medial unicompartmental knee arthroplasty (UKA) is associated
with successful outcomes in carefully selected patient cohorts.
We hypothesised that severity and location of patellofemoral cartilage
lesions significantly influences functional outcome after Oxford
medial compartmental knee arthroplasty. Patients and Methods. We reviewed 100 consecutive UKAs at minimum eight-year follow-up
(96 to 132). A single surgeon performed all procedures. Patients
were selected based on clinical and plain radiographic assessment.
All patients had end-stage medial compartment osteoarthritis (OA)
with sparing of the lateral compartment and intact anterior cruciate ligaments.
None of the patients had end-stage patellofemoral OA, but patients
with anterior knee pain or partial thickness chondral loss were
not excluded. There were 57 male and 43 female patients. The mean
age at surgery was 69 years (41 to 82). At surgery the joint was
carefully inspected for patellofemoral chondral loss and this was documented
based on severity of cartilage loss (0 to 4 Outerbridge grading)
and topographic location (medial, lateral, central, and superior
or inferior). Functional scores collected included Oxford Knee Score
(OKS), patient satisfaction scale and University College Hospital
(UCH) knee score. Intraclass correlation was used to compare chondral
damage to outcomes. Results. All patients documented significant improvement in pain and improved
functional scores at mid-term follow-up. There were four revisions
(mean 2.9 years, 2 to 4; standard deviation (. sd). 0.9) in
this cohort, three for tibial loosening and one for femoral loosening.
There was one infection that was treated with debridement and insert exchange.
The mean OKS improved from 23.2 (. sd. 7.1) to 39.1 (. sd. 6.9);

scale. On the UCH scale, patients reported significantly decreased
mean overall scores (7.3, . sd. 1.2 vs 9, . sd. 2.3)

Abstract. Introduction. Elite athletes sustaining a graft re-rupture after ACL reconstruction (ACL-R) undergo revision reconstruction to enable their return to elite sport. The aim of this study was to determine the rate of return to play (RTP) and competition levels at 2 and 5 years post revision ACL-R. Methodology. A consecutive series of revision ACL-R in elite athletes undertaken by the senior author between 2009 and 2019 was retrospectively reviewed. Outcome measures were RTP rates and competition level. Results. Forty-nine athletes underwent revision ACL-R and were included. 87.8% returned to elite sport of which 75.5% were at the same level. At 2 years post-surgery, 79.6% were still playing, 51% at the same level; and at 5 years 44.4% were still playing, 20% at the same level. Athletes with > 50% thickness
Introduction. Femoroacetabular impingement(FAI) is a relatively common cause causes of hip pain and dysfunction in active young adults. The concept of FAI was popularized by Ganz et al in early 2000s. Surgical treatment for FAI has been widely employed over the last two decades. The long term outcome of femoroacetabular osteoplasty (FAO) and risk factors for long-term failure of FAO is less studied. The goal of this single surgeon series is to identify the long term outcome of FAO (minimum 10-year follow-up) and risk factors for surgical treatment failure in these patients. Methods. The prospective database on hip joint preservation identified 1,120 patients who have undergone FAO between January 2005-June 2019. Of these 164 patients (178 hips) have a minimum 10-year follow-up (range, 10–14). The database collects detailed information on patient demographics, clinical history, radiographic and cross sectional imaging findings, intraoperative findings (site and size of
Knees of patients with chronic anterior cruciate ligament instability and who were awaiting surgery were examined with respect to increasing co-morbidity following diagnosis and subsequently during surgical reconstruction. 141 patients were included in this study. All had undergone initial arthroscopic evaluation of their unstable knees following diagnosis and subsequently a further arthroscopy was performed at a later stage during hamstring anterior cruciate ligament reconstruction. All injuries to the menisci and articular cartilage were recorded using a standardised evaluation form. The Lysholm and Tegner scores were obtained as well as knee stability using the KT-2000 arthrometer. Successive deterioration in the Lysholm and Tegner scores and the arthrometric side to side difference was noted with time since injury. Initial arthroscopic examination of the knee revealed that 66 patients (46%) had at least one meniscal injury necessitating treatment whilst 67 (47.5%) had at least one

Introduction and Objectives: Currently ACL reconstruction is one of the most frequent procedures in Trauma and Orthopedic Surgery. The aim of our study is to analyze the epidemiology of this lesion in the workplace. Materials and Methods: We retrospectively reviewed 268 cases of ACL reconstruction using autologous semitendinosus and rectus medialis muscles. All these surgeries were performed at Fremap Majadahonda during 2005–2006. We excluded patients with concomitant lesion of the PCL and revision surgeries of ACL plasties. We compared the findings of the preoperative MRI and findings during surgery with respect to existent meniscal and
Background. Cartilage lesions in chronic lateral ligament deficiency are common with the incidence rates mentioned in the previous literature up to 30%. However, other intra-articular pathologies in the unstable ankle have received little attention. Anterolateral impingement associated with synovitis and scarring is a less recognised feature in the treatment of chronic instability. The aim of our study was to ascertain the incidence of chondral and anterolateral impingement lesions in the symptomatic lateral ligament complex deficiency. Methods. We performed a retrospective study of all consecutive patients who underwent modified Brostrom repair for symptomatic recurrent instability of the ankle. All patients underwent a MRI scan prior to surgery. Arthroscopy was performed in all the patients before lateral ligament reconstruction. Seventy seven patients with 78 ankles were included in the study. Patients who had previous ankle surgery or inflammatory arthropathy were excluded. Data was obtained from clinical and radiological records. Arthroscopic findings were recorded in detail during the surgery. Results. The mean age was 29.8 years (Range 18.2–58 yrs). There were 44 females and 34 males in the study. The incidence of
