Purpose: Since the pathomechanism of patellofemoral malalignment is complex, multifactorial and varies individually, the ideal treatment has been a matter of controversy. The purpose of this study was to demonstrate the clinical outcome and radiographic changes of knees with patellofemoral malalignment treated with Fulkerson osteotomy after a minimum follow-up of 24 months. Materials and Methods: Sixty knees in 40 patients (32 female and 8 male) were examined with a mean of 55 20 (25 97) months after having undergone medialization of the tibial tubercle using Fulkerson osteotomy for patel-lofemoral malalignment. Mean age at surgery was 20 7 (12 42) years. Prior surgery of medial retinacular plication in 4 knees and lateral retinacular release in 1 knee had been performed. During surgery, amount of tibial tubercle transfer was determined by examining the patellar tracking over full range of knee motion. After Fulkerson osteotomy, proximal realignment procedures were added depending on arthroscopic appearance of the patellofemoral adaptation. The clinical outcome was evaluated using Fulkersons knee instability scale. The radiographic parameters including congruence angle, lateral patellofemoral angle, tilting angle and lateral shift ratio were measured in Merchant view. Results: Mean distance of medial transfer of tibial tubercle was 12.8 3.1 (8 22) mm. Lateral retinacular release in 54 knees and adductor magnus tenodesis (Avikainen procedure) in 2 knees were simultaneously performed combined with Fulkerson osteotomy. All radiographic parameters at the final follow-up were significantly improved compared to the preoperative values (p < 0.05 in a paired t-test), that is, from 23.0 14.6 to 0.4 13.7 degrees in congruence angle, from −6.3 9.0 to 0.4 6.9 degrees in lateral patellofemoral angle, from 25.1 11.5 to 16.3 5.6 degrees in tilting angle and from 35 24 to 17 9% in lateral shift ratio. Mean score in Fulkersons knee instability scale was 96 5 points at the final follow-up. All knees except 3 were ranked as excellent, very good or good. Two knees with moderate osteoarthritis of the patellofemoral joint were ranked as fair. One knee that had postoperative recurrence of patellar subluxation underwent a revision surgery with Avikainen procedure. Discussion: In the clinical study with a minimum 2-year follow-up, Fulkerson tibial tubercle osteotomy provided excellent or good overall outcome in 93% of patients in combination with proximal realignment surgeries. Although all radiographic parameters were significantly improved, it was found that the lateral shift of the patella was more effectively corrected compared to the lateral tilt. It was suggested that reconstruction of the medial patellofemoral structures might be more suitable than Fulkerson osteotomy for some knees characterized by significant lateral tilt

Objectives. To assess the effectiveness of a modified tibial tubercle osteotomy as a treatment for arthroscopically diagnosed chondromalacia patellae. Methods. A total of 47 consecutive patients (51 knees) with arthroscopically proven chondromalacia, who had failed conservative management, underwent a modified Fulkerson tibial tubercle osteotomy. The mean age was 34.4 years (19.6 to 52.2). Pre-operatively, none of the patients exhibited signs of patellar maltracking or instability in association with their anterior knee pain. The minimum follow-up for the study was five years (mean 72.6 months (62 to 118)), with only one patient lost to follow-up. Results. A total of 50 knees were reviewed. At final follow-up, the Kujala knee score improved from 39.2 (12 to 63) pre-operatively to 57.7 (16 to 89) post-operatively (p < 0.001). The visual analogue pain score improved from 7.8 (4 to 10) pre-operatively to 5.0 (0 to 10) post-operatively. Overall patient satisfaction with good or excellent results was 72%. Patients with the lowest pre-operative Kujala score benefitted the most. Older patients benefited less than younger ones. The outcome was independent of the grade of chondromalacia. Six patients required screw removal. There were no major complications. Conclusions. We conclude that this modification of the Fulkerson procedure is a safe and useful operation to treat anterior knee pain in well aligned patellofemoral joints due to chondromalacia patellae in adults, when conservative measures have failed

The aim of this study was to evaluate the functional and clinical outcome following medial patello-femoral ligament reconstruction using autogenous hamstring tendon grafts for patellar instability. Over a 4 year period the senior author operated on 35 patients for lateral instability of the patella. The predominant initiating event was a sporting injury. Each patient had either failed conservative management including physiotherapy, or failed surgical management including tibial tuberosity transfer. Post-operatively, all patients were allowed full flexion and extension. Sporting activity was restricted until 4-6 months post-operatively. Patients were evaluated clinically and functionally. The Fulkerson score was utilised pre- and post-operatively. The minimum follow-up was 6 months, the mean follow-up was 20 months. There were 18 males and 17 females. The mean age was 24.6 years. The mean pre-operative Fulkerson score was 59.3 (range 6-100). The mean post-operative Fulkerson score was 83.6 (range 25-100), the mean improvement was 24.3. 24 patients returned to sporting activities. The main complications were one patient with a patella fracture that was stabilised with internal fixation, one patient requiring exploration and reinforcing the ligament which had attenuated. Both patients finally had a good clinical outcome. Our study has shown that symptomatic lateral instability of the patella can be effectively treated with a medial patello-femoral ligament reconstruction and result in overall good clinical and functional outcome. We would recommend this technique

Patella recurrent dislocation and patellofemoral pain syndrome instability many young people and especially athletes. In the present study we present the results of the extension mechanism realignment through the Fulkerson oblique osteotomy of the tibial tuberosity and soft tissue balancing. During the last two years 10 patients (7 men, 3 women, mean age 29.3/ range 20–39) were treated operatively for recurrent dislocation of the patella using the Fulkerson procedure. All patients underwent knee arthroscopy for the treatment of potential chondral damage or loose bodies and for lateral retinacular release. After that we performed oblique tibial tuberosity osteotomy, medialization and internal fixation with 2 cortical screws. This oblique osteotomy allows also the anteriorization of tibial tuberosity as we move it medially. In addition, we performed medial placation. All the patients used functional knee brace locked to 0° right after the operation and with gradual ROM increase till the 8th p.o. week. The patients had no initial or long term complication. During their last follow up examination had a painless knee with full ROM and marked improvement of the patella tracking. The mean Lysholm score was 90.5. No patella dislocation was referred. Our findings show that the Fulkerson osteotomy procedure, with an additional intervention on the lateral and medial patella retinacular, is an excellent option for the treatment of recurrent patella instability and relief of the patellofemoral pain

Introduction. Recurrent patellar dislocation is often reported in bilateral knees in young active individuals. The medial patellofemoral ligament (MPFL) tear is the attributable cause behind many of them and warrants reconstruction of the ligament to stabilize the patellofemoral joint. Besides, trochleoplasty and Fulkerson's osteotomy are some other procedures that are performed to treat this problem. This study aimed to compare the clinical and functional outcomes in a cohort of patients with single-stage bilateral realignment procedures vs staged procedures. Methods. It was a retrospective matched cohort study with prospectively collected data. A total of 36 patients (mean age-26.9 years, range 13 years to 47 years) with recurrent patellar dislocations, who underwent a surgical correction in both the knees, were divided into two matched groups (age, sex, follow-up, and type of procedure). Among them, 18 patients had surgeries in one knee done at least six months later than the other knee. The remaining 18 patients had surgical interventions for both knees done in a single stage. Lysholm, Kujala, Tegner, and subjective knee scores of both groups were compared and analyzed. The rate of complications and return to the theatre were noted in both groups. Results. With a mean follow-up of 7.3 years (2.0 years to 12.3 years), there was a significant improvement in PROMS observed in both the groups (p<0.05). No significant difference could be found between the two groups in terms of the Lysholm, Kujala, and subjective knee scores (p> 0.05). The rate of complication and the re-operation rate was comparable in both the groups (p>0.05). Conclusion. The outcomes of staged vs simultaneous surgeries for bilateral patellofemoral instability are comparable. Our results indicate that simultaneous bilateral surgical correction is safe. This can potentially be an option to reduce the surgical cost and perioperative morbidity. However, careful selection of cases, choice of the patient, and the scope of rehabilitation facilities are some of the other factors that should be considered

Background. Patellofemoral replacement is an established intervention in selected patients with severe isolated patellofemoral osteoarthritis. FPV (Wright Medical, UK) is a third generation patellofemoral arthroplasty implant and is the second most used after AVON in National Joint Registry for England and Wales. Reports of survivorship and functional of this implant are scarce in literature. Aim. Evaluation of functional outcome and survivorship following FPV patellofemoral arthroplasty. Methods. FPV patellofemoral arthroplasties performed by multiple surgeons in a teaching hospital between 2004- 2008 were followed up (mean 3.5 years) with radiographs and functional outcome scores (Oxford Knee Score, Kujala score and Fulkerson score) and survival analysis was performed. Results. One hundred consecutive FPV patellofemoral joint arthroplasties were performed during this period in 81 patients (70 female). The mean age at the time of the surgery was 62 years (Range 44-82 years). Latest functional outcome was Oxford Knee Score (mean 29 out of 48), Kujala score (mean54 out of 100) and Fulkerson score (mean 65 out of 100). Three patients were lost to follow up due to death, none of these had been revised. There were 14 revisions, twelve of which were converted to total knee replacement and two revised to further FPV. The cumulative five year survival analysis was 84.1%. Conclusion. Although inferior to total knee replacement results, the results from our study are comparable to those in the national joint registry. FPV patellofemoral arthroplasty gives satisfactory initial results and can be considered as a bone ligament sparing option in patients with isolated patellofemoral arthritis which can be readily be revised to total knee replacement if necessary

Introduction. There are numerous surgical techniques for medial patellofemoral ligament (MPFL) reconstruction. Problems with certain techniques include patellar fracture and re-rupture. Aim. To investigate the functional outcomes of MPFL reconstructions performed using a free gracillis tendon graft, oblique medial patella tunnel and interference screw femoral fixation. Patients were selected for MPFL reconstruction if they had recurrent patellar dislocations, and with the use of clinical and radiographic evaluation. Methods. A prospective case series of 31 consecutive knees in 28 patients underwent reconstruction of the MPFL using a free gracillis tendon graft, oblique medial patella tunnel and interference screw femoral fixation. Our primary outcome measure was the Kujala patellofemoral questionnaire. This was assessed preoperatively and postoperatively at 6 weeks and 3, 6, 9, 12, 18, 24 months and at final follow up. Secondary outcome measures included Fulkerson patellofemoral scores at the same time intervals, return to work, return to preoperative sport and complications. Results. The median follow up time was 25 months (range 12 – 44 months). Kujala scores improved from 58 to 93 (p < 0.002) and Fulkerson scores improved from 58 to 95 (p < 0.002) pre- and postoperatively respectively. The median return to work was 8 weeks and return to preoperative sport was 11 weeks. There were 2 revisions as a result of trauma. There were no instances of patellar fracture in this case series. Conclusions. MPFL reconstruction using a free gracillis tendon graft, oblique medial patella tunnel and interference screw femoral fixation appears to be an effective surgical intervention for patellar instability. This technique also reduces the risk of patellar fracture, a common shortcoming with many other techniques

Introduction. Current problem – Multiple surgical interventions for patellar instability and no defined criteria for use of medial patellofemoral ligament (MPFL) reconstruction. Aims. Investigate the functional outcomes of MPFL reconstructions that had been performed following selection for treatment based on a defined patellar instability algorithm. Methods. Study design – prospective case series. Treatment number – 19 knees in 17 patients. Intervention – medial patellofemoral ligament reconstruction using free gracillis tendon graft. Inclusion critieria – Recurrent patellar dislocation with a trochlear groove - tibial tubercle (TG-TT) offset of 20mm or less, and trochlear dysplasia and patellar alta classed as normal, mild or moderate. Primary outcome measure – Kujala patellofemoral questionnaire, assessed preoperatively and postoperatively at 6 weeks and 3, 6, 9, 12, 18, 24 months and at final follow up. Secondary outcome measures – Fulkerson patellofemoral scores, return to work, return to preoperative sport and complications. Results. Median follow up time was 24 months (range 12 – 36 months). Kujala scores improved from 58 to 96 (p < 0.05) and Fulkerson scores improved from 56 to 95 (p < 0.05) pre- and postoperatively respectively. The median return to work was 8 weeks and return to preoperative sport was 12 weeks. There was one complication of post-operative stiffness, which settled with intensive physiotherapy. There were no instances of repeat dislocation or patellar fracture. There were no cases needing further surgery. Conclusions. MPFL reconstruction, when performed following selection using our defined treatment algorithm is safe and effective for the treatment of patellar instability. Longer follow up is required to see long term outcomes

Aim: The purpose of this study is to evaluate the long term results of modified Elmslie-Trillat procedure. We have also reviewed the various modifications and its outcome seen in the literature to the original conventional Elmslie-Trillat procedure. Our modified surgical technique is described. Materials and Methods: The patients were evaluated functionally using Kujala and Fulkerson scoring system. Clinical examination was performed to look for patella apprehension, tracking of patella, crepitus and range of movement. X rays were done to look for degenerative changes. The primary end point in our study was evidence of recurrent instability and the secondary end point was functional scoring and evidence of degenerative changes. Results: Out of 38 patients and 42 knees available from our records from 1991 to 2005, 16 patients and 20 knees were available for functional and clinical review. The mean age at operation was 27 years. The average follow up was 9 years. 74% of the knees scored excellent to good with kujala and Fulkerson scoring. There was no episode of recurrent dislocation post-operatively in our series. Minimal degenerative changes were noted in 15% of knees. 37% of knees needed removal of screw. 58% of knee had some numbness around the scar. 80% of them returned back to original occupation. 60% of them went back to original sporting levels. All patients felt happy to recommend the operation. Conclusion: We conclude that our modified Elmslie-Trillat surgical procedure is very successful in eliminating recurrent patellar dislocation and instability. We present the literature available on the various modifications of Elmslie-Trillat procedure and its outcome

Aim. We report the results of a modified Fulkerson technique of antero-medialisation of the tibial tubercle, combined with microfracture or abrasion arthroplasty in patients under 60 with patello-femoral osteoarthritis. Methods. All patients operated between September 1992 and October 2007 were reviewed by an independent observer in clinic or by postal questionnaire, using the Oxford Knee Score, Melbourne Patella Score and a Satisfaction Score. Only patients with Outerbridge Grade 3-4 osteoarthritis of the patello-femoral joint were included. They were assessed pre-operatively with plain x-rays, MRI scans (as well as tracking scans in the last 10 years) and arthroscopically. All patients with tracking scans showed lateral subluxation of the patella. The surgical procedure was a modification of Fulkerson's tibial tubercle osteotomy, with an advancement of 1-1.5cms and a medialisation of 1.5cms. The exposed bone of the patella and trochlea was drilled in the early cases and in the later cases an arthroscopic microfracture or abrasion using a power burr was carried out. Results. Between September 1992 and October 2007, 103 procedures were carried out in 84 patients, 19 patients having staged bilateral procedures. The mean follow-up was 84 months (range 24-204 months). The mean age was 45 (range 26-59) and the female to male ratio was 7.6:1. 70 patients were reviewed (follow-up rate of 82%). The mean Oxford Knee Score was 18.5 pre-operatively (range 3-32) and 34.3 post-operatively (range 11-47). The Melbourne Patella Score was 9.6 pre-operatively (range 3-30) and 20 post-operatively (range 11-30). Patient Satisfaction Scores were excellent (54%), good (29%), fair (8.5%) and poor (8.5%). 4 knees in 3 patients were converted to a patello-femoral arthroplasty, giving a 10 year survival rate of 96.1%. Conclusion. This procedure offers an alternative to patello-femoral arthroplasty for younger patients with isolated patello-femoral arthritis

We report the results of a modified Fulkerson technique of antero-medialisation of the tibial tubercle, combined with microfracture or abrasion arthroplasty in patients under 60 with patello-femoral osteoarthritis.

We performed an advancement and medial transfer of the tibial tuberosity based on Fulkerson's principle to treat intractable anterior knee pain associated with patellofemoral maltracking diagnosed by dynamic MRI. Between January 1998 and July 2000 twenty-two patients had 28 knees operated for anterior knee pain. There were 4 men and 18 women with a mean age of 28 years (range 18-41). Indications for surgery were [a] failure to improve after six months of physiotherapy and [b] patellofemoral maltracking evident in dynamic MRI. Mean follow-up was for 37 months (23 – 42). Knee instability score modified by Fulkerson was employed for objective and subjective assessment. Objectively 22 (79%) knees achieved good to excellent results. Four knees (14%) had fair, and two (7%) had poor results. Excellent and very good results were seen in 20 knees. These patients were a younger age group (mean age 21 years) and had minimal degeneration (grade I-II) of the patellofemoral joints. Two patients achieved good results. One of them had moderate (grade III) and one minimal (II) arthritis. Three knees with fair results had advanced (grade IV or V) and one had moderate (grade III) arthritis. Out of two patients who had a poor result, one had advanced degeneration (grade V) that later required a patellofemoral joint resurfacing. The other was a 24 year old woman with grade II changes. She was treated by the pain therapy team. Anterior displacement of the tuberosity in the presented study was kept to 5 mm to avoid the possible complications of wound break down. The overall length and depth of the osteotomy was also reduced to minimise risk of fracture and commence early mobilisation. Based on our results there is a strong case of justification for Anteromedialisation of tibial tuberosity using a smaller length of osteotomy and lesser degree of anteriorisation in carefully selected patients with Patellofemoral arthralgia associated with maltracking patella

Aims: Patellar instability and painful patellar mal-tracking are common challenging conditions faced by a knee surgeon. Our purpose was to describe an arthroscopy assisted method of medial patellofemoral ligament reconstruction to address these conditions present our results using this modified technique. Materials & Method: Between April 2001 and December 2003, 22 knees in 20 consecutive patients underwent arthroscopically assisted MPFL reconstruction using an autologous hamstring tendon. There were 12 female and 8 male patients passed with a mean age of 29.9 years. The knees were assessed using Fulkerson’s and Kujala’s scoring systems and the mean follow-up period was 20.8 months (range 12–35). The technique uses a single hamstring tendon with undisturbed biological distal attachment, where the free end is routed through a longitudinal tunnel in the dorso-medial aspect of the patella and fixed to an isometric point near the medial femoral epicondyle using an interference screw. The position of femoral attachment is the most important factor in achieving an isometric graft. Results: There was a significant increase (p=< 0.0001) in mean Fulkerson score of 35.4 from a pre-operative value of 47.4 to a post-operative value of 82.9. Sixteen patients rated their knees as good or excellent and there was only one complication of complex regional pain syndrome. 11 of 13 patients who were keen on sports returned to their sports at a mean of 3.9 months (range 1–10). Conclusion: We report good results with this technique of medial patello femoral ligament reconstruction and would advocate it as an effective surgical option for patients with recurrent lateral instability as well as those with painful lateral mal-tracking

This study is a prospective analysis of clinical outcome in 201 consecutive patients treated with medial patellofemoral ligament reconstruction using an autologous semitendinosus graft between October 2005 and January 2011. Patients received pre and post-operative clinical evaluation, radiological assessment and outcome scoring systems. 193 patients (92 male, 119 female) underwent 211 procedures, with mean age 26 (16–49) and follow-up 16 months (6–42 months). Indications were atraumatic recurrent patella dislocation (68%), traumatic recurrent dislocation (22.8%), instability (5%), single dislocation (2.7%) and anterior knee pain (1.4%). Trochlea dysplasia was moderate in 57% and mild in 35%. There have been no recurrent dislocations/ subluxations. 10 patients have required further surgery. The mean pre-op Kujala Scores were 55 (SE 5.21) and post-op scores improved to mean 82 (31–100) (SE 1.18)(p < 0.001). This improvement and significance is mirrored with Oxford (27 to 41), WOMAC (76 to 93), Fulkerson (53 to 83), IKDC (46 to 75), Tegner (4.1 to 5.3) and SF12 (38 to 51) scores (p < 0.005). 93% of patients were satisfied with their operation. History of prior realignment surgery was associated with significantly worse outcomes compared to patients where MPFL reconstruction was their first realignment procedure (p < 0.05). This series is the largest reported in the literature for any technique of MPFL surgery. This technique allows for objective intra-operative evaluation of the required graft tension to optimise patella tracking

To assess the clinical outcomes of patients undergoing ACI in the patellofemoral joint. Level of evidence. Therapeutic study, Level II-1 (prospective cohort study). In a prospective study to determine the clinical effectiveness of autologous chondrocyte implantation 130 patients reached a minimum follow up of two years (range, 2–9 years, average 56.5 months) after treatment involving the patellofemoral articulation. There were 77 men (59%) and 53 women (41%) with an average age of 37.5 years (range, 15-57years). The treatment groups included I) isolated patella, n = 14; II) isolated trochlea, n = 15; III) patella plus trochlea, n = 5; IV) weight bearing condyle plus patella n = 19; V) weight bearing condyle plus trochlea, n = 52; VI) weight bearing condyle plus patella plus trochlea n = 25. The average surface area per patella, n = 63, was 4.72 cm2 and per trochlea, n = 98, was 5.8cm2. The average resurfacing per knee, n = 130, was 11.03cm2. This prospective outcome study demonstrated a significant postoperative improvement in quality of life as measured by the SF-36; WOMAC, Knee Society Score, modified Cincinnati Score and a patient satisfaction survey. There were 16 failures (12%) as a result of a patella or trochlea failure. Eighty percent of patients rated their outcomes as good or excellent, 18% rated outcome as fair, and 2% rated outcome as poor. ACI is effective in the patellofemoral joint and specifically is a complementary intervention for those patients that will predictably do poorly with an isolated Fulkerson Tibial Tubercle osteotomy

Aims: Anterior knee pain is a common complaint of mixed aetiology, and in many cases no demonstrable cause is identified. For patients with persistant anterior knee pain, tibial tubercle transfer (TTT) can be a surgical option. The aim of this study is to assess the effectiveness of TTT for chronic anterior knee pain resistant to conservative treatment. Method: All patients with arthroscopically proven Chondromalacia patellae (CMP) without clinical evidence of patella instability, who have failed to respond to conservative treatment such as physiotherapy were included in the trial. They underwent TTT with a modified Fulkerson technique and then routine post-operative care with a cricket pad splint for 2–4 weeks. Pre and post-operative scores were obtained using a Kujala patello-femoral score, a visual analogue score for pain and a patient satisfaction score. The Outerbridge grading was used to score the severity of CMP at arthroscopy. Results: There were 50 TTT’s followed up (7 staged bilaterals) with a mean follow up of 32.4 months (5–88 months). There were significant improvement in the pre-operative and post-operative Kujala (p> 0.001) and visual analogue pain scores (p> 0.001). Of the 50 TTT’s 70% had an excellent or good result and 30% a fair or poor result. Moreover 76% claimed that they would have the same operation again for their condition. There was no significant correlation between Outerbridge grading and post-operative outcome. Complications include late anterior knee pain (10 cases), superficial wound infection (1 case), non-union of osteotomy (1 case) and tuberosity fracture (1 case). Conclusion: Anteromedial tibial tubercle transfer is a reliable and effective treatment for peristant anterior knee pain

Introduction: Regional anaesthesia is used recently more often in minor and intermediate orthopaedic procedures. This study evaluates regional anaesthesia in knee arthroscopy. Patients and Method: From September 2002 to February 2003, sixty three patients had knee arthroscopy by regional blockade, (mean age 28, 3 years). Thirty ml Ropivacaine 5% and 10 ml Lidocaine 2% were used to block sciatic and femoral nerve with nerve stimulator help. Results: They were realized 31 meniscectomies, 8 meniscal repairs, 6 primary ACL reconstructions, 2 ACL revisions, 5 chondroplasties, 6 lateral releases, 2 Fulkerson osteotomies, 4 plica removals, 2 adhesionlysis, 2 localized villonodular synovitis, one total synovectomy and one arthroscopic removal prepatellar bursa. There was no complication concerning the nerve blockade. Two of 8 ACL patients required general anesthesia and one had sedation during the procedure. Sedation also was necessary in three patients with lateral release and two meniscal repairs. The remaining 55 patients were tolerated the arthroscopic procedure without any additional help. All patients hospitalized less than 24 hours except patients with ACL reconstruction. They needed 1, 2 analgesic pills per person. The cost for the anesthetic procedure was 40 euros. Conclusion: Regional anesthesia has the advantage of avoiding the complications of general anesthesia, is of low cost and well bearable from the majority of patients. It offers prolonged postoperative analgesia and has no complications

Introduction and Aims: To describe the arthroscopically assisted technique of medial patello-femoral ligament reconstruction using a hamstring tendon and evaluate the results of the procedure. Since April 2001 the senior author has performed 20 cases. One was bilateral. Average age was 30 years (range 17–52). Method: The study group comprised nine males and 11 females. The indication for surgery was recurrent lateral dislocation in 13 and lateral mal-alignment in the remaining seven. Thirteen of the 20 had undergone prior surgery, eight an isolated lateral release and five a lateral release combined with open extra-synovial medial retinacular plication. Key features of this technique are use of the 70-degree arthroscope in the supero-lateral portal, endoscopic lateral release and use of semitendinosis or gracilis tendon attached distally. The tendon is passed through drill holes in the medial aspect of the patella and attached to a clinically isometric point near the medial femoral condyle. The tension is assessed arthroscopically and clinically before attachment. The semitendinosis tendon was used in 11 cases and gracilis in 10. Results: All had subjective improvement with regard to patellar instability, activity level and relief of pain. There were no recurrent dislocations. The only patient in whom the tendon was attached to the distal adductor magnus required revision surgery with improvement after attachment of another tendon to bone at the isometric point. Mean follow-up was 17 months (range 4–33 months). The mean time to return to work was five weeks (range five days–12 weeks) and return to sport 10 weeks (range 3–16 weeks). The Fulkerson patello-femoral joint evaluation score improved from 46/100 pre-operatively to 74/100. Only four described the state of the knee subjectively as fair and the rest good or excellent. All patients regained full range of motion. Conclusion: This arthroscopically assisted technique of medial patello-femoral ligament reconstruction using a hamstring tendon allows the patella to be seen and felt to articulate in the trochlea groove. It allows early rehabilitation, minimal post-operative pain, provides patella stability and significant functional improvement with rapid recovery and a low incidence of skin numbness

Objectives

The objective of this study was to determine if the use of fascia lata as a tendon regeneration guide (placed into the tendon canal following harvesting the semitendinosus tendon) would improve the incidence of tissue regeneration and prevent fatty degeneration of the semitendinosus muscle.
